Answer:

f(g(-8)) = -26

Step-by-step explanation:

Given:

f(x)=2x and g(x)=2x+3

Required:

f(g(-8))=?

Solution:

First we will find g(-8)

g(x) = 2x+3

g(-8)= 2(-8)+3

= -16 + 3

= -13.

so, g(-8) = -13

Now, for calculation f(g(-8)) we can put the value of g(-8) i.e, -13

so, f(x) = 2x

f(-13) = 2(-13)

= -26

so, f(-13) = -26

and f(g(-8)) = -26

Answer:

$\text{Volume of cat box}=3.52\text{ ft}^3$

Step-by-step explanation:

We have been given that Mrs. Backstrom built a small wooden box for her cat. The box has a length of one and one tenth feet, a width of 1.6 feet, and a height of 2 feet. We are asked to find the volume of the box.

Let us convert one and one tenth feet into decimal.

$1\frac{1}{10}=\frac{11}{10}=1.1$

Since the cat box is in form of cuboid, so its volume will be equal to the product of length, width and height as:

$\text{Volume of cat box}=1.10\text{ ft}\times 1.6\text{ ft}\times 2\text{ ft}$

$\text{Volume of cat box}=3.52\text{ ft}^3$

Therefore, the volume of the cat box is 3.53 cubic feet.

I don't know how to answer the top two and I don't know if the bottom one is correct, help me please

1) How many 3/4 does it take to make 9/2?

     Now look at this, 3/4 x 6 = 4 1/2. 4 1/2 is the same as 9/2

   3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 ---> takes 6, 3/4's to make 9/2

2) How many 3/4's go into 9/2?

    This is the same question as the 1st one so the answer is 6 :)

3) 9/2 divided by 3/4 = ??

         Use the KEEP< CHANGE< FLIP method, so it turns into I

                                                                                                    I
      9/2 x 4/3                       < -------------------------------------          I

This is equal to 36/6 which is 6 :)

The answer is 6 for numbers 1, 2, and 3 :)

D is wrong. It’s an exponential function so every year the number of stores it opens grows. Which means there can’t be one number for each year in terms of amount of new stores.
