Answer:
d) 8
Step-by-step explanation:
It’s c because 3075/15=205, 3000/15 + 75/15 = 200+5, and 200+5=205 so 205=205 which is true. C is the answer
The area of the circle is expressed in the formula A = pi r^2 while the formula of getting the circumference of the circle is C = 2pi *r. Trying to express A in terms of C, we square C first into C2 = 4pi^2r^2. In this case, the answer to this problem therefore is A = C^2/4 pi. Answer is B
The equation of y for that expression would be y = (-4x+9)/-5.

The process of computing the "average rate of change", however, remains the same as was used with straight lines: two points are chosen, and is computed.<span>FYI: </span>You will learn in later courses that the "average rate of change" in non-linear functions is actually the slope of the secant line passing through the two chosen points. A secant line cuts a graph in two points.</span></span></span>
When you find the "average rate of change" you are finding the rate at which (how fast) the function's y-values (output) are changing as compared to the function's x-values (input).
When working with functions (of all types), the "average rate of change" is expressed using<span>function notation.</span>
