Answer:
from what i know, the answer should be 36
using the expression l*w*1/2 you find the areas of the 4 smaller triangles, then you add then together. i did that, and got 36.
i would reccomend says 40, its the closest to the truth.

Answer:
(e) f′(x)=2xg(x)+x²g′(x)
Step-by-step explanation:
The product rule applies.
(uv)' = u'v +uv'
__
Here, we have u=x² and v=g(x). Then u'=2x and v'=g'(x).
f(x) = x²·g(x)
f'(x) = 2x·g(x) +x²·g'(x)
Answer:
Area of the square = 36
We can assume that the total area of the 4 circle sections is equal to the area of one circle with a 3 inch radius.
Area of Circle = PI * 3 * 3
Area of white region = 36 - PI * 9

Answer:
The value of f(-4) = -80
Step-by-step explanation:
It is given that, f(x) = -5x²
<u>To find the value f(-4)</u>
Let f(x) = -5x²
To find the value of f(-4), substitute -4 instead of x
f(-4) = -5 * (-4)²
= -5 * 16 [ since (-4)² = -4 * -4 = 16 ]
= -80
Therefore the value of f(-4) = -80
Answer:
x=1, y=2
Step-by-step explanation:
x + 7y = 15
x + 2y = 5
Subtract the two equations
x + 7y = 15
-x - 2y =- 5
------------------------
0x +5y = 10
Divide by 5
5y/5 = 10/5
y =2
Now find x
x+2y = 5
x +2(2) = 5
x +4 = 5
Subtract 4 from each side
x-4+4 = 5-4
x = 1
