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
It’s a function
hope you have a good day
Lightly draw a vertical line at -3 (x= -3 is the divider) on the left side graph x + 1, on the right side graph 1/2x + 2.
because these equations don't match up at the -3 coordinate, you have to draw an open (not colored in) circle at the beginning at the 1/2x-2 equation
14x0.75=10.5
15-10.5=4.5
so she will get $4.50c
Hope this helps! :D
Answer:
1/63
Step-by-step explanation:
There are a couple of ways to do this.
<h3>1) </h3>
Look for the GCF of the numerators when a common denominator is used.
GCF(3/7, 4/9) = GCF(27/63, 28/63) = (1/63)·GCF(27, 28)
GCF(3/7, 4/9) = 1/63
__
<h3>2) </h3>
Use Euclid's algorithm. If the remainder from division of the larger by the smaller is zero, then the smaller is the GCF; otherwise, the remainder replaces the larger, and the algorithm repeats.
(4/9)/(3/7) = 1 remainder 1/63*
(3/7)/(1/63) = 27 remainder 0
The GCF is 1/63.
__
* The quotient is 28/27 = 1 +1/27 = 1 +(1/27)(3/7)/(3/7) = 1 +(1/63)/(3/7) or 1 with a remainder of 1/63.

<em>Additional comment</em>
3/7 = (1/63) × 27
4/9 = (1/63) × 28
