by the function $s = (200d)^1^/^2$ where s is the speed (in miles per hour) that the tsunami is traveling and d is the average depth (in feet) of the wave.

a. Find the inverse of the function.

b. Find the average depth of the tsunami when the recorded speed of the wave is 250 miles per hour.

Answer:

a) $d = \frac{s^2}{200}$

b) 312.5 ft

Step-by-step explanation:

Given:

Average speeds, $s = (200d)^1^/^2$

a) To find the inverse of the function.

$s = (200d)^1^/^2$

s² = 200d

200d = s²

$d = \frac{s^2}{200}$

Therefore, inverse of the function =

$d = \frac{s^2}{200}$

b) average depth when speed is 250 miles per hour.

Average depth = d

Therefore, let's use the formula :

$d = \frac{s^2}{200}$

$= \frac{250^2}{200}$

$= \frac{62500}{200}$

d = 312.5 feet

The average depth when speed is 250 miles per hour is 312.5 ft

Answer:

Answer Below

Step-by-step explanation:

Triangle #1

To solve this answer we need to multiply then divide by 2

$3$ x $8=24$

$24$ ÷ $2=12$

Triangle #2

Now we do the same thing!

$3$ x $8=24$

$24$ ÷ $2=12$

Rectangle #1

Now we solve for the rectangle!

$6$ x $8 = 48$

Now we add all these together!

$12 + 12 + 48 = 72$

The answer is D. 72 Square Units
