Answer:

28.26658805 (I included every digit in case your teacher needs you to round)

Step-by-step explanation:

In order to find x, we need to isolate x by subtracting 15^2 and taking the square root of both sides.

Thus, we have:

15^2+x^2=32^2\\x^2=32^2-15^2\\\sqrt{x^2} =\sqrt{(32^2-15^2)} \\\sqrt{x^2}=\sqrt{799}  \\x=28.26658805

3. PLEASE HELP! Jenna just opened a checking account at the bank. Within the first month, she deposited three checks for $34.98,
sashaice [31]

Answer:C) She would have $216.88.

Step-by-step explanation:

A) Deposits:  +34.98; +51.02; +51.22

Withdrawals:  -5.23; -5.22; -7.89

B) -7.89, -5.23, -5.22, +34.98, +51.02, +51.22

The smallest amount will be the largest withdrawal, as it takes away from the account; the largest amount will be the largest deposit, as it adds to the account.

98 + 34.98 = 132.98 + 51.02 = 184.00 + 51.22 = 235.22 - 7.89 = 227.33 - 5.23 = 222.10 - 5.22 = 216.88

The functions f and g are defined as follows.
g100num [7]

Answer:

f(-5)=-16\\g(2)=-11

Step-by-step explanation:

By definition, a relation is a function if and only if each input value have one and only one output value.

The input values are the x-values and the output values are the y-values.

Given the function f(x):

f(x)=3x-1

You need to substitute x=-5 into this function:

f(-5)=3(-5)-1

And now you must evaluate in order to find the corresponding output value.

You get:

f(-5)=-15-1\\\\f(-5)=-16

The function g(x) is:

g(x)=-2x^2-3

Then, you need to substitute x=2 in the function:

g(2)=-2(2)^2-3

And  finally you must evaluate in order to find the corresponding output value. This is:

g(2)=-2(4)-3\\\\g(2)=-8-3\\\\g(2)=-11

A machine used to make badges costs $120. It costs $5 to make each badge. Write a function to show the total cost f(n) of making
vladimir1956 [14]
First, I find it helpful to write the function myself.

There is a set fee of $120, and $5 per <em>n</em> badges.

<em />120 + 5<em>n
</em>
This is a basic model. Now we can see if any match.

f(n) = 5<em>n</em> + 120 matches. 

Let me know if you found any errors.
