The graph of f(x) = 2x + 1 is shown below. Explain how to find the average rate of change between x = 1 and x = 3.Graph of 2 to the power of x plus 1

Answers

Answer 1

Answer:

So we got the function of the graph f(x) = 2^x + 1 what you will need to do first is find the y-coordinates corresponding to x=1 and x=3 which can be found by substituting into the function. After that we can find the average rate of change using y2-y1/x2-x1.

f(1)=2^1+1 which would be equal to 3

1,3

f(3)=2^3+1 which would be equal to 9

3,9

9-3/3-1=6/2

6/2=3

The average rate of change is 3.

1)we calculate the volume of the right rectangular prism
volume=lenght x width x heigth
volume=12 ft * 8.5 ft * 4 ft=408 ft³

density= mass / volume ⇒ mass=volume * density.
density=0.25 pound /ft³

2) we calculate the mass of the right rectangular prism.
mass=volume * density
mass=408 ft³(0.25 pound / ft³)=102 pounds.

Miley music has a sale on music CDs all music CDs are discounted 15% Marianas receipt indicates that she saved $3 on her CD purchase what is the full price of her music CD before the discount

Answers

Answer: The original price of her music CD before discount is $20.

Step-by-step explanation:

Let x be the original price of her music CD.

Discount rate = 15%

At discount she saved = $3

So, According to question, our equation becomes

15%x= 3

0.15x= 3

x=$20

Hence, the original price of her music CD before discount is $20.

If x is the price before a sale
x-0.15x=x-3
0.85x=x-3
3=0.15x
x=20

The original price is $20

Solve the equation for Q.
R = T - RQ

Answer:

$\huge\boxed{Q=(T-R)/(R)=(T)/(R)-1}$

Step-by-step explanation:

$R = T - RQ\qquad|\text{add}\ RQ\ \text{to both sides}\n\nR+RQ=T-RQ+RQ\n\nR+RQ=T\qquad|\text{subtract}\ R\ \text{from both sides}\n\nR-R+RQ=T-R\n\nRQ=T-R\qquad|\text{divide both sides by} \ R\neq0\n\n(RQ)/(R)=(T-R)/(R)\n\nQ=(T-R)/(R)\n\nQ=(T)/(R)-(R)/(R)\n\nQ=(T)/(R)-1$
