Answer:

Option b is correct Step-by-step explanation:

The direct variation says that: , then the equation is of the form: where, k is the constant of variation.

As per the statement:

If y varies directly as x.

By direct variation: ….

If y = 18 when x = 5

Substitute these values in  we have; Divide both sides by 5 we have; or  ……

We have to find the value of y when x = 11.

Substitute x = 11 in  we have; Therefore, the value of y is, [ad_2]

Okay so you need to distribute the -7.
1.) -7 times 3e which equals -21e
*negative times a positive equals a negative
2.) -7 times -2f which will equal to 14f
*negative times a negative equals a positive
3.) -7 times 4 which equals -28

which leaves you with the equation -21e + 14f -28 + 6e – 2
now just combine like terms, like -21e and 6e or -28 and -2

1.) -21e + 6e will equal to -15e
2.) -28 + -2 will equal to -30

So at the end it will be simplified down to
Answer: -15e + 14f – 30

## What the graph of the quadratic function is

[ad_1]

Y=x²+x-6 (original form ax²+bx+c)

1) this is a parabola open upward since the coefficient of x² is positive
so it has a minimum.

2) Its symmetry line = -b/2a = -1/2 & for x=-1/2, y= 23/4
So its minimum is (-1/2, 23/4)

3) Now to see if the parabole intercepts the x-axis we calculate the roots of
x²+x-6. As you will notice Δ <0 so there is no roots & consequently it doesn’t intersect with x-axis
Your graph is wrong, and the parabola should be above the x-axis & it will intersect with the y-axis at y=23/4 =5.75nunits

i would just make this into an equation!!
t for the number of turkey sandwiches
s for the number of steak sandwiches

it’s 4 dollars for every turkey sandwich and 6 for every steak sandwich, so:
4t + 6t = 4524
you can call this your “profit” equation. it just tells you how much money they made. however many sandwiches they sold at those rates gave them the outcome of 4524

then you need a second equation, to account for the number of sandwiches, and instead of worrying about profit you need to focus on the number of sandwiches sold (which is why they gave you the number 925)
t + s = 925

the number of turkey sandwiches plus the number of steak sandwiches adds up to a total of 925 sandwiches.

so you have two equations:
4t + 6s = 4524
t + s = 925

to figure out the number of turkey sandwiches sold, you want to solve for the variable t. this can be done a few ways with your two equations, but the easiest to follow will probably be substitution in this case.

first, isolate your variable t in one of the equations. it’ll be easier with the second one.
t = 925 – s

then you plug that into your first equation:

4(925 – s) + 6s = 4524
then solve it like normal.

4(925 – s) + 6s = 4524
3700 – 4s + 6s = 4524
3700 + 2s = 4524
2s = 824
s = 412

so now you know your s variable. plug that back into the following equation, and you have the number of turkey sandwiches sold:
t = 925 – s
t = 925 – (412)
t = 513

513 turkey sandwiches were sold

Answer:

Global maxima are (3, 0) and (-3, 0),

Local minima is (0, -1.62)

Step-by-step explanation:

Here, the given function, Differentiating with respect to x, For maxima or minima,    Thus, the critical points of the function f(x) are 0, -3 and 3,

Since, f'(x) > 0 on the left side of x = -3 and f'(x) < 0 on the right side of x = -3,

⇒ x = -3 is local maxima,

Also, f(-3) = 0,

f(x) has maxima at (-3, 0),

f'(x) < 0 on the left side of x = 0 and f'(x) > 0 on the right side of x = 0,

⇒ x = 0 is the local minima,

Also, f(0) = -1.62

function f(x) has minima at (0, -1.62),

Hence, the global maxima are (3, 0) and (-3, 0),

Local minima is (0, -1.62).

f'(x) >  0 on the left side of x = 3 and f'(x) < 0 on the right side of x = 3,

⇒ x = 3 is local maxima,

Also, f(3) = 0,

function f(x) has maxima at (3, 0).

Note : function f(x) has no global minima because its end behaviour is,  [ad_2]

Answer: O₃

Explanation:

The term isoelectronic means same number of electrons.

Then you need to count the number of electrons in the given species NO₂⁻.

You have to count the number of electrons of N (nitrogen) atoms, the number of electrons of two O (oxygen) atoms, and the adjust for the negative charge of the ions.

The atomic number of N is 7, meaning that each atom has 7 protons and 7 electrons.

The atomic number of O is 8, meaning that each atom has 8 protons and 8 electrons.

The negative charge of the ion means that it has one extra electron, which is the responsible for the negative charge.

Therefore the total number of electrons of the ion NO₂⁻ is 7 + 2 (8) + 1 = 24.

Note that that 24 = 3 x 8, so 24 is the number of electrons in 3 atoms of oxygen.

The moleucle O₃ is an allotrope of the oxygen. (an allotrope is a a form of an element with different structure and physical properties in the same physical state).

Therefore, the allotrope of oxygen isoelectronic with NO₂⁻ is O₃ (ozone)

Answer:

The maximum number of acres of barley the farmer can plant and still be under budget would be of 123 acres.

Step-by-step explanation:

The farmer grows two types of seeds, with a budget of \$10,000. He has spent \$4,200 in wheat seed, and wants to know the maximum number of barley he is able to plant.

First of all, as \$10,000 – \$4,200 is equal to \$5,800, that is the amount of money he is able to spend in barley seeds.

As every acre of barley seed costs \$47 to plant, in order to know how many acres he can plant we have to do the following calculation:

5,800 / 47 = maximum of acres the farmer can plant

5,800 / 47 = 123.40

The maximum number of acres of barley the farmer can plant and still be under budget would be of 123 acres.

Answer:

Hazel has to spend \$36.36

\$36 and 36 cents.

Step-by-step explanation:

The given box is a rectangular box. To find the felt needed to cover the box, we need to find the surface area of the rectangular prism.

Surface area of a rectangular prism = 2(l*w + w*h + h*l), where “l” is the length, “w” is the width and “h” is the height of the rectangular prism.

Given: l = 11 inches; w = 8 inches; and h = 6 inches.

Now plug in these given values in the above formula, we get

Surface area of the rectangular prism = 2 (11* 8 + 8*6 + 6*11)

Let’s simplify it.

= 2(88 + 48 + 66)

= 2(202)

= 404

The surface area of the rectangular prism = 404  square inches.

The felt cost 9 cents square inches.

Convert 9 cents to dollar.

9 cents = \$0.09

To find the cost of the felt needed to cover prism multiply 404 by 0.09

The total cost = 404*0.09 = \$36.36

There are four variables which govern changes in population size.
births
deaths
immigration
emigration

A population gains individuals by birth and immigration and loses individuals by death and emigration.

Biotic Potential
Populations vary in their capacity to grow. The maximum rate at which a
population can increase when resources are unlimited and environmental
conditions are ideal is termed the population’s biotic potential. Each
species will have a different biotic potential due to variations in
the species’ reproductive span (how long an individual is capable of reproducing)
the frequency of reproduction (how often an individual can reproduce)
“litter size” (how many offspring are born each time)
survival rate (how many offspring survive to reproductive age)

There are always limits to population growth in nature. Populations
cannot grow exponentially indefinitely. Exploding populations always
reach a size limit imposed by the shortage of one or more factors such
as water, space, and nutrients or by adverse conditions such as disease,
drought and temperature extremes. The factors which act jointly to
limit a population’s growth are termed the environmental resistance. The interplay of biotic potential and density-dependent environmental resistance keeps a population in balance.
Carrying Capacity
For a given region, carrying capacity is the maximum number of
individuals of a given species that an area’s resources can sustain
indefinitely without significantly depleting or degrading those
resources. Determining the carrying capacities for most organisms is
fairly straightforward. For humans carrying capacity is much more
complicated. The definition is expanded to include not degrading our
cultural and social environments and not harming the physical
environment in ways that would adversely affect future generations.

For populations which grow exponentially, growth starts out slowly,
enters a rapid growth phase and then levels off when the carrying
capacity for that species has been reached. The size of the population
then fluctuates slightly above or below the carrying capacity.
Reproductive lag time may cause the population to overshoot the carrying
capacity temporarily. Reproductive lag time is the time required for
the birth rate to decline and the death rate to increase in response to
resource limits. In this scenario, the population will suffer a crash
or dieback to a lower level near the carrying capacity unless a large
number of individuals can emigrate to an area with more favorable
conditions. An area’s carrying capacity is not static. The carrying
capacity may be lowered by resource destruction and degradation during
an overshoot period or extended through technological and social
changes.

An example of dieback occurred in Ireland after a fungus infection
destroyed the potato crop in 1845. During this potato famine
approximately 1 million people died and 3 million people emigrated to
other countries. Increased food production due to improved agricultural
practices, control of many diseases by modern medicine and the use of
energy to make historically uninhabitable areas of Earth inhabitable are
examples of things which can extend carrying capacity. The question is
how long will we be able to keep increasing our population on a planet
with finite size and resources?

Answer:  The answer is (B), (C) and (E).

Step-by-step explanation: We are given five options out of which we are to select all those which can be modelled by exponential functions.

We can see that the options (A) and (D) cannot be modelled by exponential functions, because the rate of increasing or decreasing are not calculating compoundly.

But, in options (B), (C) and (E), the rate is increasing or decreasing each year.So, these three can be modelled by exponential functions.

In fact, the options (B) and (E) will show exponential growth because the number is increasing and option (C) will show exponential decay as the number is decreasing.

Thus, (B), (C) and (E) are the correct options.

we have the equation y = 1.09x, that describes the number of yards y in x meters.

a) Yes, if you have negative numbers of x (this means negative meters, this is used usually to denothe something that is behind the observer) then the equation transform them into negative yards.

b) in this case you want to know how many meters are in 40yd, then we replace y by 40yd in the equation:

40 = 1.09x

x = 40/1.09 = 36.7 meters

## What is the function of the electron transport chain?

[ad_1]

Passive Transport: Simple Diffusion

Diffusion across a cell membrane is a type of passive transport, or transport across the cell membrane that does not require energy. Remember that the cell membrane is a phospholipid bilayer. Although the inside and the outside of a cell are both water-based, there is a hydrophobic region in the middle, and this is an important barrier to anything large, charged, or hydrophilic. Molecules that are hydrophobic, just like the hydrophobic region, can pass through the cell membrane by simple diffusion.

Therefore, simple diffusion is the unassisted passage of small, hydrophobic, nonpolar molecules from a higher concentration to a lower concentration. Very small molecules can slip through the cell membrane, too, even if they are hydrophilic – just like a few ants might crawl through a crack in the wall just because they’re tiny.
