Answer:
Third side is 15cm. Perimeter is 37cm.
Step-by-step explanation:
In a triangle sum of two sides is always greater than third side. Two sides of a isosceles triangle are equal.
So if the third side is 7cm
7+7=14cm which is less than 15 cm.
hence third side is 15 cm as
15+15=30cm which is greater than 7cm
15+7=22cm which is greater than 12cm
then
perimeter=15+7+15=37cm
Answer:
- 6
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ 1, 5 ]
f(b) = f(5) = 17 - 5² = - 8
f(a) = f(1) = 17 - 1² = 16
average rate of change = 
= 
= - 6
