Answer:
f(3) = 10
Step-by-step explanation:
f(x)=-x^2+19
Let x= 3
f(x)=- (3)^2+19
= -9 + 19
= 10
19/25 = x/100
Cross multiply:
1,900
Divide 1,900 by 25
Equals 76
Subtract 76 from 100
Answer: 24% change

The computation shows the radius of the circle that is inscribed in the isosceles triangle will be 3.33cm.
<h3>How to calculate the radius?</h3>
From the information given, the isosceles triangle the length of a base is 10 cm and the length of a leg is 13 cm.
Let A = area of the triangle
Let S = semi perimeter of the triangle.
The radius will be: = A/S
where,

The radius will be:

= 3.33cm
