## The brain mass of a fetus can be estimated using the total mass of the fetus by the function b equals 0.22 m superscript 0.87b=0.22m0.87?, where m is the mass of the fetus? (in grams) and b is the brain mass? (in grams). suppose the brain mass of a 2323?-g fetus is changing at a rate of 0.240.24 g per day. use this to estimate the rate of change of the total mass of the? fetus, startfraction dm over dt endfraction dm dt.

We are given
b = 0.22 m^0.87
db/dt = 0.24 g/day at b = 23 g

where
b is the brain mass of the fetus
m is the total mass of the fetus
db/dt is the rate of change of the brain mass of the fetus

We are asked to get the rate of change of the total mass of the fetus

First, we take the first derivative of the given equation with respect to time
db/dt = 0.22 (0.87) m^(0.87-1) dm/dt
Next, simplify and substitute the given values. So,
0.24 g/day = 0.22(0.87)(23)^(0.87 -1 ) dm/dt
Solving for dm/dt
dm/dt = 1.88 g/day

The rate of change of mass of the fetus is 1.88 g/day.

127=7 (mod n) means when 127 is divided by n, the division leaves a remainder of 7.

The statement is equivalent to
120=0 (mod n), meaning that n divides 120.

All divisors of 120 will satisfy the statement because 120 divided by a divisor (factor) will leave a remainder of 0.

Factors of 120 are:
n={1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120}, |n|=16.
You can count how many such values of n there are, and try to check that each one satisfies 127=7 mod n.

## The daily profit p in dollars of a company making tables is described by the function upper p left parenthesis x right parenthesis equals negative 5 x squared plus 240 x minus 2475 p(x)=?5 x 2+240x?2475?, where x is the number of tables that are manufactured in 1 day. the maximum profit of the company occurs at the vertex of the parabola. how many tables should be made per day in order to obtain the maximum profit for the? company

The following equation of parabola is given:

p(x)= – 5 x^2 + 240 x – 2475

where p(x) = y

This is a standard form of the parabola. We need to
convert this into vertex form of equation. The equation must be in the form:

y – k = a (x – h)^2

Where h and k are the vertex of the parabola. Therefore,

y = – 5 x^2 + 240 x – 2475

y = -5 (x^2 – 48 x + 495)

Completing the square:

y = -5 (x^2 – 48 x + 495 + _) – (-5)* _

Where the value in the blank _ is = -b/2

Since b = -48        therefore,

y = -5 (x^2 – 48 x + 495 + 81) + 405

y – 405 = -5 (x^2 – 48 x + 576)

y – 405 = -5 (x – 24)^2

Therefore the vertex is at points (24, 405).

The company should make 24 tables per day to attain maximum
profit.

## If 3/4 of a cup of juice equals 100% of your daily vitamin C. then what percent of your daily value of vitamin C will you get in 1 cup of juice?

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.

## According to the law of conservation of mass in a chemical reaction the total starting mass of all the reactants equals the total final mass of all the products true or false

The coefficient of CO₂ is 5.

Explanation:

Balancing the reaction:

___C₅H₁₂ + ___O₂ → ___CO₂ + ___H₂O

There are 5 C in the left side, so we put 5 on the right side:

___C₅H₁₂ + ___O₂ →  5CO₂ + ___H₂O

There are 12 H in the left side, so we put 6 as the coefficient of H₂O:

___C₅H₁₂ + ___O₂ →  5CO₂ + 6H₂O

Finally, there are 16 O in the right side, so we put 8 as the coefficient of O₂

___C₅H₁₂ + 8O₂ →  5CO₂ + 6H₂O

The coefficient of CO₂ is 5.

## Find the​ mean, variance, and standard deviation of the binomial distribution with the given values of n and p. n equals 123n=123​, p equals 0.85

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.

## HELP ASAP!!! An electron in a hydrogen atom moves from level 1 to level 4. The electron then drops from level 4 to level 2. Which statement describes the most likely result? The energy absorbed in the first move equals the energy released in the second move. The energy absorbed in the first move is greater than the energy released in the second move. The energy released in the first move equals the energy absorbed in the second move. The energy released in the first move is greater than the energy absorbed in the second move.

A positive cahnge of enthalpy, ΔH rxn = + 55 kJ/mol, for the forward reaction means that the reaction is endothermic, i.e. the reactants absorb energy and the products are higher in energy.

Activation energy is the difference in the energy level of the reactants and the peak in the potential energy diagram (the energy of the transition state).

For an endothermic reaction, the products will be closer in energy to the transition state than what the reactans will be; so, the activation energy of the reversed reaction is lower than the activation energy of the forward reaction.

Activation energy of reverse and forward reactions is related by:

Activation energy of reverse rxn = Activation energy of forward rxn – ΔH rxn

=> Activiation energy of reverse rxn = 102 kJ/mol – 55 kJ/mol = 47 kJ/mol

## The position of a simple harmonic oscillator is given by x left-parenthesis t right-parenthesis equals left-parenthesis 0.50 mright-parenthesis cosine left-parenthesis startfraction pi over 3 endfraction t right-parenthesis where t is in seconds. what is the maximum velocity of this oscillator?

The formula for computing the orbital time period of a body is given as:

T² = 4π²r³ / GM

where T is the time period, r is the distance between the two bodies, G is the gravitational constant and M is the mass of the body that is being orbited. If we compute this time using SI units, the working is:

9.58 AU is 1.43 x 10¹² meters

T = √[(4*π²*(1.43 x 10¹²)³) / (6.67 × 10⁻¹¹ * 2 x 10³⁰)]
T = 9.30 x 10⁸ seconds which is approximately 29 years

Using the astronomical units, distance is in astronomical units and the mass is in solar masses. In these conditions, the ratio:
4π²/G = 1 so

T² = a³ (since the solar mass of the sun is 1)

T = √(9.58)³
T = 27 years

## Can you use the Law of Cosines if you are given a = 41, b = 55 and the measure of angle A equals 56 degrees ?

Step-by-step explanation:

As we know for a regular polygon sum of all interior angles is represented by  n A = 180 (n-2)

and sum of all exterior angles is represented by n A’ = 360°

Here n represents number of sides of the polygon.

Now we will go for each options given.

(A) Decagon : (Having 10 sides)

(1) 8A = 180 ( 8-2 )

8A  = 180 × 6

A = = 160°  ( interior angle )

(2) n A’ = 360°

8 A’ = 360°

A = 45°     ( exterior angle )

(B) Pentagon ( having 5 sides )

(1) 5A = 180 ( 5-2 )

5A = 180 × 3 = 540

A = 108°   ( interior angle )

(2) 5A’ = 360

A’ = 72°    (exterior angle )

(C) Dodecagon : ( having 12 sides )

(1)   12A  = 180 (12-2)

12 A = 180 × 10 = 1800

A = 150°  ( interior angle )

(2) 12 A’ = 360

A’ = 30°   ( exterior angle )

(D) 16-gon  ( having 16 sides )

(1)   16 A = 180 ( 16 – 2 )

16A = 180 × 14

16 A  = 1520

A  = 157.5°    ( interior angle )

(2)  16 A’  = 360

A’ = 22.5°

(E)  25-gon   ( having 25 sides )

(1)   25 A = 180 ( 25-2)

25A = 180  (23)

A = 165.6°     ( interior angle )

(2)  25A’  =  360

A  = 14.4°    ( exterior angle)

## There are 2 numbers. Twice the first number minus the second number equals 18. Twice the second number minus the first number equals 9. Find the numbers.

Infinite number of solutions…means it will be the same line.
you have probably heard about equivalent fractions like 1/2 = 2/4…and if u reduce 2/4, it equals 1/2. Well…there are also equivalent equations. They can also be reduced.

3y = 2x – 9 cant be reduced, but u can make an equivalent equation by multiplying it all by a number.Any number.

lets try 2…
2(3y = 2x – 9) =
6y = 4x – 18…this is an equivalent equation….the same line..infinite solutions.Notice that u can reduce it by dividing everything by 2 which would equal 3y = 2x – 9….so u see, it is like equivalent fractions….kind of…lol

or multiply it by 3
3(3y = 2x – 9) =
9y = 6x – 27….this is also equivalent…..so this is an answer as well

and u can multiply it by 4 and get another equivalent equation..or 5, or 6….and so on…

make any sense ?? Just remember, to get the result of infinite solutions, the equations have to be equivalent
