Answer:
18 sq ft
Step-by-step explanation: all you have to do is add the sides. 5+5=10
4+4= 8
10+8=18
This makes the most sense with the answers givin
Answer:
3.5
Step-by-step explanation:
If you divide x from y on each row, you will always get 3.5
After substituting in for x and y with the given values, the answer is 10/3 or 3.3333 repeating
Answer:
Step-by-step explanation:
Given
(a) to (d)
Required
Which will give:
Equate the expression in bracket to g(x)
Replace g(x) with x in:
A critical point is just where a graph's slope is = to 0, so you can take the derivative of that function and set it equal to 0.
Using the chain rule:
f'(x) = 5(x-10)^4
0 = 5(x-10)^4
divide by 5 on both sides and take the 4th root of both sides.
0 = x - 10
add ten on both sides, and x = 10. Now, plug the x-value back into the original (you want to find the y-value on the original function ,not the derivative).
y = (10-10)^5 = 0
(10,0)
