Step-by-step explanation:
To find an inverse function:
first, write y in place of f(x)
second, switch the x and y.
third, solve for y.
last, replace y with inverse function notation, f^-1(x)

Step-by-step explanation:
Positive Integer factors of 330 = 2, 3, 6, 5, 30, 11, 330 divided by 2, 3, 5, 11, gives no remainder. They are integers and prime numbers of 330, they are also called composite number.
Step-by-step explanation:
Number of choices = 5C2 = 5 * 4 / (1 * 2) = 10.
Using the given equation, set H to 8 meters and solve for t:
8 = 3 + 20t -5t^2
Subtract 8 from each side:
3 + 20t -5t^2 -8 = 0
Simplify:
20t - 5t^2-5 =0
Factor out -5:
-5(t^2-4t+1)=0
Divide both sides by -5:
t^2 - 4t +1 = 0
Using the quadratic formula solve for t:
t = 2 +/- √3
t = 3.73 or 0.27
