Answer: c
Step-by-step explanation:
We are given the relation between the height (in feet) and the distance (in miles) as follows:
y = sqrt(1.5x + (x/5280)^2).
We want to know the height (x) that makes the distance (y) = 10 miles
So, we will simply substitute in the above equation with y = 10 and calculate x as follows:
10 = sqrt(1.5x + (x/5280)^2)
we will square both sides to get rid of the root:
100 = 1.5x + (x/5280)^2
1.5x + (x/5280)^2 - 100 = 0
(x-66.11475)(x+7986.1147) = zero
either x = 66.11475 feet (accepted solution)
or x = -7986.1147 feet (rejected solution as no height is in negative)
If you multiply 23 by 12 you will get 276.

Answer:
let's say cells is c and hours are x that means there are 15 cells each hour. the equation for that is c=15x
after 08 hours the cells have multiplied 8 times their original size. meaning that the equation changes to this: c=15x x=8 c= 15(8)
x equals 8 at that time.. literally
ok the cells have multiplied and now there are 120 cells in total
then after one day the cells have multiplied over 12 times afterwards. now x equals 24. the equation would look a little like this:
c=15x x=24 c= 15(24)
there are 360 cells now.
Explain in your own words the relationship between x=8 with x=24 in the equation.
