Answer: I believe the answer is around/about 56.55

Step-by-step explanation: C=2πr=2·π·9≈ 56.54 or aound 56.52

Formula: C=2πr

Simplified Equation:

2 x 3.14 x 9= 56.52 - 56.55

Good luck!! I hope this helps! All you have to do is memorize the formula, break down & simplify the numbers and equation and you're golden!!

Find the inverse of the function. f(x) = the cube root of quantity x divided by seven. - 9

elena-14-01-66 [18.8K]

To solve

replace f(x) with y
switch x and y
solve for y
replace y with f⁻¹(x)

so
I'm not sure if it is
$f(x)=\sqrt[3]{\frac{x}{7}}-9$ or
$f(x)=\sqrt[3]{\frac{x}{7}-9}$

first one
$f(x)=\sqrt[3]{\frac{x}{7}}-9$
replace f(x) with y
$y=\sqrt[3]{\frac{x}{7}}-9$
switch x and y
$x=\sqrt[3]{\frac{y}{7}}-9$
solve for y
$x+9=\sqrt[3]{\frac{y}{7}}$
$(x+9)^3=\frac{y}{7}$
$7(x+9)^3=y$
replace y with f⁻¹(x)
$f^{-1}(x)=7(x+9)^3$

2nd one
$f(x)=\sqrt[3]{\frac{x}{7}-9}$
replce f(x) with y
$y=\sqrt[3]{\frac{x}{7}-9}$
switch x and y
$x=\sqrt[3]{\frac{y}{7}-9}$
solve for y
$x^3=\frac{y}{7}-9$
$x^3+9=\frac{y}{7}$
$7(x^3+9)=y$
replace y with f⁻¹(x)
$f^{-1}(x)=7(x^3+9)$

if you meant $f(x)=\sqrt[3]{\frac{x}{7}}-9$ then the inverse is $f^{-1}(x)=7(x+9)^3$

if you meant $f(x)=\sqrt[3]{\frac{x}{7}-9}$ then the inverse is $f^{-1}(x)=7(x^3+9)$

Brady is buying two DVDs online. One site sells the DVDs for $12.75 each and if the total purchase price is more than $25, shipp

gizmo_the_mogwai [7]

Answer:

He will pay $25.5

Step-by-step explanation:

Hello, I can help you with this

you can solve this finding the total price of each option

Step 1

option 1

the DVDs for $12.75 each and if the total purchase price is more than $25, shipping is free; otherwise, shipping is $3.75.

Brady needs 2 DVDs so

2*$12.75=$25.5

and

$25.5 is more than $25, so the total price is

$25.5

Step 2

option 2

the DVDs for $11.95 each, plus $2.75 shipping.

Brady needs 2 DVDs so

(2*$11.95)+$2.75=$26.65

and

$26.65 is more than $25.5, so Bradly chooses the option 1 ($25.5), He will pay $25.5

I hope it helps, Have a great day.
