use the function below:
trig graph with points at 0, 1 and pi over 2, negative 1 and pi, 1 and 3 pi over 2, 3 and 2 pi, 1
what are the amplitude and midline?
amplitude: 1; midline: y = 1
amplitude: 2; midline: y = 1
amplitude: 2; midline: y = 2
amplitude: 2; midline: y = 0

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
