(0,8) I think is correct..
Answer:
The year 2021.
Step-by-step explanation:
75% here means a the answer to our function is 75.
Thus, f(t) = 75
Now let's solve the equation for the variable t:
Solving for t using the quadratic formula we get:
t1 = 21.477
t2 = -6.124
As t is the number of years after 2000, and t can not be less than 0, our answer is t1.
This mean the percent is predicted to reach in the middle of the year 2021.
converting the number 0.477 to months we get: 0.477*12 = 5.72
This means the middle of may.
So our answer is May, 2021. And the year is just 2021.

Hello from MrBillDoesMath!
Answer:
(3b -a) / ( 1 + b^2)
Discussion:
My best guess is that we are trying to simply this fraction:
( 3 - a/b) / ( (1/b) + b) = => multiply num. and denom. by "b"
(3b - a) / ( (1/b)*b + b*b) =
(3b -a) / ( 1 + b^2)
Thank you,

Answer:
16 feet wide
Step-by-step explanation:
Use the proportion
1 in is to 8 feet as 2 inches is to 'x' feet.
1/8 = 2/x
now solve by cross multiplying
x = 16 feet
