Answer:
The arrow can be broken into a rectangle and a triangle.
And the area of the arrow is 22 ft^2
Step-by-step explanation:
Area of the rectangle:
length • width = 7 • 2 = 14 ft^2
Area of the triangle:
(base • height) / 2
You must add 1 + 2 + 1 in order to get the base which is 4
And to get the height, you must do 11 - 7 = 4 (height)
(4 • 4) / 2 = 8 ft^2
Add both areas together to get the area of the arrow:
14 ft^2 + 8 ft^2 = 22 ft^2

Answer:
<u>f(-8) = 64</u>
Step-by-step explanation:
<u>Given conditions</u> :
<h3>f(x) = { x², if x < 0}</h3><h3>or </h3><h3>f(x) = {∛x, if x > 0}</h3>
<u>We have x = -8</u>
⇒ It follows x < 0
Therefore, substituting x = -8 in the function :
- f(-8) = (-8)²
- <u>f(-8) = 64</u>
