Answer:
A) 106 ft^2
Step-by-step explanation:
The total surface area is the area of the base triangular face and the three lateral faces.
The base triangular face has length of its base to be b=6 ft.
The height of this triangle is 5.2 ft.
The area of this triangle is


to the nearest integer
The area of the three lateral face is

The total surface area is therefore 90+16=106 square feet

Hello!

y = 2x³ + ax² - x + 3
Find the derivative using the power rule:
y' = 6x² + 2ax - 1
Substitute in the given slope and x value to solve for a:
3 = 6(1)² + 2(1)a - 1
3 = 6 + 2a - 1
4 = 6 + 2a
-2 = 2a
a = -1
