An acorn drops from a tree into a pond and creates a ripple with a radius that increases at a rate of 10 cm/sec. The radius of the ripple can be expressed as the function R(t) = 10t, where t represents time in seconds. The area of the circle made by ripple can be expressed as the function A(r) = πr2 , where r represents the radius in centimeters. Which function can be used to determine the area of the ripple as a function of time?

step-by-step explanation:

every 5 customers that walk in, only 2 buy popcorn.

step-by-step explanation:

basically 2/5.

brainliest would be appreciated.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
