Answer:

Step-by-step explanation:

f(x) = 6(x+2)²-6

f⁻¹(f(x)) = x

f(x) = t => 6(x+2)²-6 = t =>

=> 6(x+2)² = t+6 =>

=> (x+2)² = t/6 + 1

=> x+2 = ±√(t/6 + 1)

=> x = ±√(t/6 + 1) - 2

=> f⁻¹(x) =

{√(x/6 + 1) - 2, x > -6

{-√(x/6 + 1) - 2, x ≤ -6

a D.J. at a school dance plans to play dance music for 2 hours. she has 20 requests for songs. Each song plays for 3 1/2 minutes

viva [34]

So, put 2 hours into minutes. You get 120. Now, seeing how you have 20 song requests, and each one takes 3.5 minutes, multiply those two values. Now you have 70. After doing that, just subtract 70 from 120 and get 50.

tada

answer is 50

Find the unknown side length x write your answer in simplest radical form

Sauron [17]

Answer:

(B) $4\sqrt{37}$

Step-by-step explanation:

First, we determine the height of the triangle which we label as y.

Using Pythagoras Theorem.

$25^2=7^2+y^2\\y^2=25^2-7^2\\y^2=576\\y=\sqrt{576}\\y=24$

In the smaller right triangle with hypotenuse, x

Base = 7-3 =4 Units

Height, y= 24 Units

Therefore, applying Pythagoras Theorem.:

$x^2=24^2+4^2\\x^2=592\\x=\sqrt{592}\\ x=4\sqrt{37}$
