Since each barber works 8 hours per day, it means that the barber shop conducts 112 haircuts in 8 hours. This means that it conducts
cuts per hour. Every barber can conduct two haircuts per hour. This means that a generic number 
of barbers conducts 
cuts per hour. But we already know that the shop conducts 14 cuts per hour, so the number of barbers is given by
Answer:
The inverse is sqrt(x+9)
Step-by-step explanation:
f(x)=x^2-9
To find the inverse of the function, we interchange x and y and solve for y
y = x^2 -9
x = y^2 -9
Add 9 to each side
x+9 = y^2 -9+9
x+9 = y^2
Take the square root of each side
sqrt(x+9) = sqrt(y^2)
sqrt(x+9) = y
f^-1 (x) = sqrt(x+9)
Given function is f(t)=0.4t
Let the number f days that have passed since the seed was planted = t
As mentioned, Julie measured and determined the height of plant after 30 days so initially the value of t = 30
But we have to find the value of f(t) at t = 10
so f(10) = 0.4*10
f(t) = 4
I believe yo meant c=2pir but ok
c=2r
divide both sides by 2
c/2=r
if you forgot tthe pi
c=2pir
divide by 2pi
c/(2pi)=r
