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:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
