Correct question :
The average speed that a tsunami (a large tidal wave) travels is represented
by the function
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)
b) 312.5 ft
Step-by-step explanation:
Given:
Average speeds,
a) To find the inverse of the function.
s² = 200d
200d = s²
Therefore, inverse of the function =
b) average depth when speed is 250 miles per hour.
Average depth = d
Therefore, let's use the formula :
d = 312.5 feet
The average depth when speed is 250 miles per hour is 312.5 ft
Answer:
45°
Step-by-step explanation:
Well, compared to 90°, it looks like it's just smaller, but not too small. It couldn't be 15° degrees, or 60°, as it was probably too much. I Don't think it's 30° either, because it looked bigger than what a 30° angle would be.
Hope it helped!
