If the cos of angle x is 5 over 8 and the triangle is dilated to be three times as big as the original, what would be the value of the cos of x for the dilated triangle? a. 15 over 24 b. 10 over 16 c. 5 over 8 d. the cos value cannot be determined for the dilated triangle.

Even though we triple the lengths of the sides of the original triangle, we do not change the value of the cosine of the angle x, because the ratio "adj / hyp" remains the same (5/8).

  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).
