URGENT! - Question worth 15 points!
The triangle is this question is not drawn accurately.
Use Pythagoras' Theorem to explain why triangle A must be right-angled.

169/13=13

Step-by-step explanation:

12*12=144

5*5=25

144+25=169

Square root of 169=13

  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).
