There is a flu outbreak at your school that starts with 10 people. the number of ill students increases by 20% each hour. write an exponential function to represent the total number of ill students, f(x), where x is the number of hours after the outbreak. how long does it take for at least 100 people to be ill with the flu?
a. about 10 hours
b. about 13 hours
c. about 20 hours
d. not enough information

d

Step-by-step explanation:

what does ' f ' represent?

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
