Answer:

384 unit^2

Step-by-step explanation:

SA = 2(lw + wh + hl)

     = 2(8x8 + 8x8 + 8x8)

     = 2(64 + 64 + 64)

     = 2(192)

     = 384

Hope it helps!

Answer:

Switch x and y, and solve for y

f^{-1}(x) =\frac{(x -4)^3}{8}

Step-by-step explanation:

Given

f(x) = 3\sqrt{8x} + 4

Required

Complete the steps to determine the inverse function

Solving (a): Complete the blanks

Switch x and y, and solve for y

Solving (b): Determine the inverse function

f(x) = \sqrt[3]{8x} + 4

Replace f(x) with y

y = \sqrt[3]{8x} + 4

Switch x and y

x = \sqrt[3]{8y} + 4

<u>Now, we solve for y</u>

Subtract 4 from both sides

x -4= \sqrt[3]{8y} + 4-4

x -4= \sqrt[3]{8y}

Take cube roots of both sides

(x -4)^3= 8y

Divide both sides by 8

\frac{(x -4)^3}{8} = y

So, we have:

y =\frac{(x -4)^3}{8}

Hence, the inverse function is:

f^{-1}(x) =\frac{(x -4)^3}{8}

BC= <br> I need someone help... anybody know how to do this?
Tems11 [23]
<h3>Answer: 10.99</h3>

Work Shown:

Angle B = 20 is the reference angle

AC = 4 is the side opposite this reference angle

BC = x is the unknown adjacent side

tan(angle) = opposite/adjacent

tan(B) = AC/BC

tan(20) = 4/x

x*tan(20) = 4

x = 4/tan(20)

x = 10.9899 approximately (make sure your calc is in degree mode)

x = 10.99 rounding to two decimal places

BC = 10.99

If a 40-foot tree casts a 16-foot shadow, find the length of the shadow cast by a 24-foot tree
Mrrafil [7]

40/16 = 24/x

16*24 = 384

x = 384 / 40

x =9.6

 it cast a shadow 9.6 feet long
