The half-life of a certain substance is years. How long will it take for a sample of this substance to decay to % of its original amount? Use the exponential decay model, , to solve. e^8x-5 -3=25,059

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
