Answer:

f(-5) = 5

Step-by-step explanation:

Step 1: Define

f(x) = -x² - 7x - 5

f(-5) is x = -5

Step 2: Substitute and Evaluate

f(-5) = -(-5)² - 7(-5) - 5

f(-5) = -25 + 35 - 5

f(-5) = -25 + 30

f(-5) = 5

The composite figure below is a triangle and a semicircle. What is the exact area of the figure? Do NOT round at any point!
Tatiana [17]
(2,3) and (-1,-5)
Distance =√(-1-2)^2 +(-5-3)^2
Distance  =√73 (diamter)
radius = (√73) / 2
 
area of semi-circle: 
= 1/2 πr^2
= 1/2  π ((√73) / 2)^2 
= 73 π / 8
= 9.125 π 

area of triangle:
= 1/2 (8)(3)
= 12

Area of the figure = area of semi-circle  + area of triangle<span>

</span>= 9.125π  + 12

answer
9.125π  + 12
