Answer:
+- square root of x+36
Step-by-step explanation:
f(x) = x^2 -36
y = x^2 -36
Exchange x and y
x = y^2 -36
Solve for y
Add 36 to each side
x+36 = y^2 -36+36
x+36 = y^2
Take the square root of each side
±sqrt(x+36) = y
±sqrt(x+36) = f^-1(x)
You can set up a ratio problem
take what you know and set it equal to what you don't know
4/6 = r/15
Cross multiply and get:
60 = 6r
divide by 6
r = 10
Answer:
<u>The correct answer is that 600 miles per hour are equivalent to 965.4 kilometers per hour</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
Convert 600 miles per hour to kilometers per hour
2. Let's proceed with the conversion:
1 mile per hour = 1.609 kilometers per hour
then:
600 miles per hour = 600 * 1.609 kilometers per hour
600 miles per hour = 965.4 kilometers per hour
<u>The correct answer is that 600 miles per hour are equivalent to 965.4 kilometers per hour</u>
