**Answer:**

The answer is 896pi in.^2

**Step-by-step explanation:**

It may seem confusing as you get an answer in the thousands by plugging in the formula, but remember they are asking you to find the answer in "terms of pi". This means you have to divide the answer by 3.14.

2814/3.14 = 896pi in^2

Hope this helped!

Solution 1

No answer choices given but i think this is it.......This budget can be modified by increasing the amount spent on food and utilities and decreasing the amount spent on clothes and rent, thereby maintaining a positive actual net income.

Question

F(x)=x 3
−6f, left parenthesis, x, right parenthesis, equals, x, start superscript, 3, end superscript, minus, 6
h(x)=\sqrt[\Large3]{2x-15}h(x)=
3
2x−15
h, left parenthesis, x, right parenthesis, equals, root, start index, 3, end index, square root of, 2, x, minus, 15, end square root
Write f(h(x))f(h(x))f, left parenthesis, h, left parenthesis, x, right parenthesis, right parenthesis as an expression in terms of xxx.
f(h(x))=f(h(x))=f, left parenthesis, h, left parenthesis, x, right parenthesis, right parenthesis, equals

Solution 1

For this case we have the following functions:

F (x) = x ^ 3-6

h (x) = 3 ^ root (2x-15)

Doing the composition of functions we have:

f (h (x)) = (3 ^ root (2x-15)) ^ 3-6

Rewriting we have:

f (h (x)) = 2x-15 - 6

f (h (x)) = 2x-21

**Answer:**

**The compound function f (h (x)) is given by:**

**f (h (x)) = 2x-21**

F (x) = x ^ 3-6

h (x) = 3 ^ root (2x-15)

Doing the composition of functions we have:

f (h (x)) = (3 ^ root (2x-15)) ^ 3-6

Rewriting we have:

f (h (x)) = 2x-15 - 6

f (h (x)) = 2x-21

Solution 2

2x - 21

Question

How does tan 135 degrees compare to tan -135 degrees

Solution 1

Evaluating the tangent function for the two values we obtain the following:

tan 135=tan(135+180)=tan 315=-1

next:

tan -135=tan(180-135)=tan 45=1

thus comparing the two we see that tan 135 is negative while tan -135 is positive

tan 135=tan(135+180)=tan 315=-1

next:

tan -135=tan(180-135)=tan 45=1

thus comparing the two we see that tan 135 is negative while tan -135 is positive

Question

Solve the system of equations below x-2y=3
2y-3y=9

Solution 1

First you solve 2y-3y=9.

Now that you have y, then you substitute y into x-2y=3 to find X

Your solution is (-15, -9)

Now that you have y, then you substitute y into x-2y=3 to find X

Your solution is (-15, -9)

Question

Instructions:Select the correct answer. Which function is the inverse of f(x)=50000(0.8)^x

Solution 1

To solve this problem you must follow the proccedure shown below:

1. You have the following function given in the problem:

f(x)=50000(0.8)^x

2. You can rewrite it as below:

y=50000(0.8)^x

3. Then, you must apply interchange the variables:

x=50000(0.8)^y

4. Now, you have:

x/50000=(0.8)^y

5. When you apply ln you obtain:

ln(x/50000)=ln(0.8)^y

ln(x)-ln(50000)=yln(0.8)

6. Now, clear y:

** y=[ln(x)-ln(50000)]/ln(0.8)**

1. You have the following function given in the problem:

f(x)=50000(0.8)^x

2. You can rewrite it as below:

y=50000(0.8)^x

3. Then, you must apply interchange the variables:

x=50000(0.8)^y

4. Now, you have:

x/50000=(0.8)^y

5. When you apply ln you obtain:

ln(x/50000)=ln(0.8)^y

ln(x)-ln(50000)=yln(0.8)

6. Now, clear y:

Question

"7 less than a number t" written as an algebraic expression is:

Solution 1

**Answer:**** The expression for the given statement is **

**Step-by-step explanation:**

**We are given a statement:**

7 less than a number t

Let the number be considered as 't'

'Less' in the above statement means subtraction operation.

The numerical value written before the 'less' operation is written after in the expression.

**Thus, the expression for the given statement is **
