What is the parent function of this equation? ln (x-3) + 4 = f(x)

[ad_1]

The parent function is the first step you have to do before graphing the equation…
with that being said…
Parent function:
(In x)

additional information:
after the parent function you then could go on to the next step which is move the graph 3 units to the right…
In(x-3)
and then 4 units up…
In (x-3) + 4

The graph of f(x) = |x| is reflected across the x-axis and translated to the right 6 units. Which statement about the domain and range of each function is correct? Both the domain and range of the transformed function are the same as those of the parent function. Neither the domain nor the range of the transformed function are the same as those of the parent function. The range but not the domain of the transformed function is the same as that of the parent function. The domain but not the range of the transformed function is the same as that of the parent function.

[ad_1]

Answer:

D. The domain but not the range of the transformed function is the same as that of the parent function.

Step-by-step explanation:

We are given,

The function f(x)=|x| is reflected across x-axis, which gives -|x|.

And then the function is translated to the right by 6 units, which gives -|x-6|.

Thus, the transformed function is g(x)=-|x-6|

So, from the graph shown below, we get,

Domain of both the functions f(x) and g(x) is set of all real numbers.

Range of f(x) is {y|ygeq 0}.

But, Range of g(x) is {y|yleq 0}.

Hence, the correct option is,

D. The domain but not the range of the transformed function is the same as that of the parent function.

A 3 year-old child has tympanostomy tubes in place. the child’s parent asks the nurse if the child can swim in the family pool. how best should the nurse respond?

[ad_1]

The answer to this question is that the nurse should
instruct the patient that the medication contains a combination of medications,
and one of which is an analgesic. Topical analgesics or also known as topical
pain killers are creams, ointments, oils, lotions, and patches that are being
rubbed and put to the skin of a patient to give relief to painful joints and
muscles. The use of topical analgesics is to avoid drinking of over the counter
pain medications.

25) Answer is: less metallic and more nonmetallic.

Electronegativity increases from left to right across a period, atoms have tendency to attract electrons.

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.

26) Answer is: radioisotope.

Radioisotope has an unstable atomic nucleus and emit energy and particles when it changes to a more stable form.

Francium (Fr) is element with atomic number 87 (87 protons and 87 electrons).

27) Answer is: boils.

Boiling is the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.

The Celsius scale was based on 0°C for the freezing point of water and 100°C for the boiling point of water at 1 atm pressure.

28) Answer is: endothermic.

There are two types of reaction:  

1) endothermic reaction (chemical reaction that absorbs more energy than it releases, ΔH>0).

2) exothermic reaction (chemical reaction that releases more energy than it absorbs).  

For example, the breakdown of ozone is an endothermic process. Ozone has lower energy than molecular oxygen (O₂) and oxygen atom, so ozone need energy to break bond between oxygen atoms.  

29) Answer is: kinetic.

The average kinetic energy of molecules depends on the temperature.  

As temperature increases, molecules gain more energy from surrounding and move faster.  

Kinetic energy (standard unit is the joule J) depends on speed of the molecule.  

Solid gains kinetic energy to become a liquid and then becomes a gas.

30) Answer is: alpha particles.

This was famous Rutherford’s Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles.

Rutherford observed the deflection of alpha particles on the photographic film.  

Alpha particles are helium atom particles, consist of two protons and two neutrons.  

According to Rutherford model of the atom: atoms have their charge concentrated in a very small nucleus.  

31) Answer is: highest.

For example, calcium oxide.

Calcium oxide (CaO) has ionic bonds between calcium cations (Ca²⁺) and oxygen anions (O²⁻).

Because it has strong ionic bonds, it has high melting point (around 2600°C).

Ionic bond is the electrostatic attraction between oppositely charged ions (cations and anions).

32) Answer is: a scientific model.

A scientific model is a representation of an idea, an object, a process or a system that is used to describe and explain phenomena that cannot be experienced directly.

33) Answer is: the superscript is mass number and the subscript is atomic number.

Atomic number(Z) is the number of protons, which is characteristic of a chemical element..

Mass number (A) is the total number of protons and neutrons in a nucleus.

There are two systems in the human body that are responsible for the coordination between the functions of different systems to achieve the unity of the living organism’s body. These two systems are the nervous system and the endocrine system. The action of the nervous system is fast and takes a short time, while the action of the endocrine system is slow and takes a long time.

The functional unit of the nervous system is the nerve cell or the neuron. The neuron consists of a cell body and the axon. The cell body starts with the dendrites that receive the messages or the impulses from other neurons or from different sense organs or receptors. These impulses are then transmitted through the cell body. The cell body contains a nucleus and different organelles which help the nerve cell to perform its functions. The nerve impulse is then transmitted to the axon.

The axon is an extension from the cell body. There are some cells called Schwan cells that secrete a myelin sheath to insulate the axon from the surrounding medium. The insulated axons have more ability to conduct the impulses than non-insulated axons. The axon ends with the terminal arborizations. The terminal arborizations of a nerve cell connect to the dendrites of the next cell or to the afferent organ. The gaps between the dendrites and the terminal arborizations are called the synapses.

The nerve impulse is an electrochemical phenomenon i.e. an electrical phenomenon with a chemical nature. The membrane of the axon acts as a barrier between an outside positively charged medium and an inside negatively charged medium. This makes a potential difference of  -70mV. This state is called the resting potential. When the membrane is subjected to a stimulus, the positive charges enter to inside and the negative charges exit to the outside. The potential difference now becomes +40mV. This state is called the depolarization state. The point of stimulation acts as a new stimulus for the next point and so on. The membrane sooner gains its permeability again and the positive charges return to the outside and the negative charges to inside. This state is called repolarization.

The nerve impulse reaches the synapse. There are some neurotransmitters that are excited by the nerve impulse coming and carry the message across the membrane. Some receptors receive theses neurotransmitters on the dendrites of the next neuron. These receptors act as a stimulus for the new cell.

A child whose parent is depressed is susceptible to depression due to genetics. Please select the best answer from the choices provided. T or F

[ad_1]

1. The answer is “C”.

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.  

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

2. The answer is “A”.

Lawrence Kohlberg felt that one of the only ways individuals will accomplish the objectives in each of his six stages was to participate in “consensus democracy” in small group settings.

Lawrence Kohlberg felt that the best way to support development through these stages was by discourse of good problems and by investment in consensus democracy inside small groups. Consensus democracy was rule by understanding of the gathering, not larger part rule. This would invigorate and widen the reasoning of youngsters and grown-ups, enabling them to advance starting with one phase then onto the next.

[ad_1]

Answer:

False

Step-by-step explanation:

Suposse that we are given a function f(x) and a constant value h.

1. Case:

If we take the function g(x)=f(x)+h, then the graph of the function g(x) will be the graph of the funcion f(x) moved up or down.

2.Case:

If we take the function g(x)=hf(x), then the graph of the function g(x) will be the graph of the function f(x) just taller or shorter.

3.Case:

If we take the function g(x)=f(x-h), then the graph of the function g(x) will be the graph of the fuction f(x) moved horizontally.

4. Case:

If we take the function g(x)=f(hx), then the graph of the function g(x) will be tha graph of the function f(x) wither or thiner.

For example:

If we take f(x)=sin(x) and h=2. Then, if we take g(x)=sin(2x) then f(0)=g(0)=0, which means that the graph of the functiction is not moved up or down. However, f(π/2)=sin(π/2)=1 and g(π/2)=sin(π)=0 which gives us a hint that the graph of the function became thiner.

The blood type is B+. The blood type depends on some protein substances called antigens present on the cell membrane of the red blood cells that help the cells to identify and communicate with each other. There are four types of blood types;
1- Blood type A which have antigens A on the red blood cells.
2- Blood type B which have antigens B on the red blood cells.
3- Blood type AB which has antigens A and B on the red blood cells.
4- Blood type O which have no antigens on the red blood cells.
There is a second type of antigens present on the red blood cells which is called rhesus. Rhesus may be present, so the individual will be positive (+) rhesus), or it may be absent, so the individual will be negative (-) rhesus.
To determine the blood type, we add anti-a and anti-b serums to two samples of the tested blood.
If the anti-a coagulates only, the person is blood type A.
If the anti-b coagulates only, the person is blood type B.
If the two samples coagulate, the person is blood type AB.
If the two samples don’t coagulate, the person is blood type O.
To another blood sample from the same blood, we add anti rhesus, if it coagulates, the person is )+), if not the person is (-).

The correct answer to this would be:

“inability of many medium ground finches to feed on large,
hard seeds”

The medium ground finches feed on seeds. However, the birds
have two variations in the bill shape: some birds have wide, deep bills while others
have thinner bills. The large-billed birds feed more proficiently on large,
hard seeds, while the smaller billed birds feed more proficiently on small,
soft seeds. The reduction in number started in 1977, when a drought period
altered vegetation on the island. Due to this event, the number of seeds
declined dramatically; the decline in small, soft seeds was larger than the
decline in large, hard seeds. The large-billed birds were able to endure better
than the small-billed birds thus resulting in decline in number.

The basis to respond this question are:

1) Perpedicular lines form a 90° angle between them.

2) The product of the slopes of two any perpendicular lines is – 1.

So, from that basic knowledge you can analyze each option:

a.Lines s and t have slopes that are opposite reciprocals.

TRUE. Tha comes the number 2 basic condition for the perpendicular lines.

slope_1 * slope_2 = – 1 => slope_1 = – 1 / slope_2, which is what opposite reciprocals means.

b.Lines s and t have the same slope.

FALSE. We have already stated the the slopes are opposite reciprocals.

c.The product of the slopes of s and t is equal to -1

TRUE: that is one of the basic statements that you need to know and handle.

d.The lines have the same steepness.

FALSE: the slope is a measure of steepness, so they have different steepness.

e.The lines have different y intercepts.

FALSE: the y intercepts may be equal or different. For example y = x + 2 and y = -x + 2 are perpendicular and both have the same y intercept, 2.

f.The lines never intersect.

FALSE: perpendicular lines always intersept (in a 90° angle).

g.The intersection of s and t forms right angle.

TRUE: right angle = 90°.

h.If the slope of s is 6, the slope of t is -6

FALSE. – 6 is not the opposite reciprocal of 6. The opposite reciprocal of 6 is – 1/6.

So, the right choices are a, c and g.

Answer:  The correct option is (C). 10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared

Step-by-step explanation:  Given that the segment AB has point A located at (8, 9). The distance from A to B is 10 units.

We are to select the correct option that could be used to calculate the coordinates for point B.

Let, (x, y) be the co-ordinates of point B.

According to distance formula, the distance between two points (a, b) and (c, d) is given by

d=sqrt{(c-a)^2+(d-b)^2}.

Therefore, the distance between the points A(8, 9) and B(x, y) is given by

d=sqrt{(x-8)^2+(y-9)^2}.

Since, distance between A and B is 10 units, so

d = 10.

Therefore,

10=sqrt{(x-8)^2+(y-9)^2}.

Thus, the correct statement is

10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared.

Option (C) is correct.

Rosa is chronically exposed to her parents’ angry, unresolved conflict. Which of the following is Rosa likely to experience? A. Stress B. Overprotectiveness C. An improvement in her performance at school D. A close secure relationship with only one parent

[ad_1]

I’m guessing on this one based on experience, and things I heard over the years.

Physical activity releases chemicals, which make you calmer and (most likely) happier after the workout. Also, exercising takes up your glucose supply. Glucose gives you energy and it’s stored in your body. This is why marathon runners often build up on carbs (where glucose is found) the day/week before the marathon. Anyways, the shortage of glucose makes you hungry. Lack of glucose= lack of energy. Lack of energy means you’re tired, which makes you want to sleep. BUT. The period between finishing the workout and feeling the need to sleep are different for everyone.

Exercising increases blood flow through the body and brain, improving everything overall, including time management. Your body is better able to tell when to be awake and when to be asleep.

Hope that helped! 🙂

Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.The tailbone in human beings is so-named because it is a homologous structure to the beginning of many animals’ tails, such as monkeys. It is known as “vestigial” because it is the last vestige of what was once a tail.All mollusks have a “foot” that they use to travel. This foot is homologous although it may not appear to be immediately – close inspection demonstrates that in terms of form and function, gastropods, cephalopods, and bivalves share this homologous structure in common.Mammals share the homologous structure of the vertebrae in common. For instance, in spite of its height, the giraffe has the very same number of neck bones (seven) as a giant whale and a tiny human being.Human beings, dogs, and cats all have similar pelvises, which are homologous structures to a vestigial pair of bones that snakes have. These bones are the last remains of a pelvis, with no legs to attach. Our eyes are homologous to the eye bulbs which blind creatures who live in caves have on their heads.All organisms contain homologous plasma membranes with what is called a phospholipid bi-layer.The wrist bone of the human being is homologous with the structures of many other animals, including the dolphin and the bird. A homologous structure in the panda looks like a sixth appendage, but it is actually a modified wrist bone that helps the panda bears pick leaves off the trees more dexterously.An auditory bone that exists inside the ear of mammals is a homologous structure to the reptile’s jaw bone (including the dinosaurs) as well as the jawbone of species of fish that are still in existence today.The carpals, metacarpals, and phalanges of the human hand have homologous structures in a variety of animals, and they’re not all mammals.  For instance, these features are seen in penguins and reptiles as well as the mammals to which human beings are more closely related.The genetic code among all living things is homologous – extremely similar although other genetic codes exist.  This suggests a common ancestor.Wasps and bees have stingers that they can use when they feel they are in danger.  However, this is a homologous structure to the ovipositor of other organisms – the feature that allows these organisms to lay eggs.
