Answer:
its the last one
Step-by-step explanation:
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)
Answer:
153
Step-by-step explanation:
You need to find the area of the triangle first which is 63. The you want to find the area of the trapezoid which is 90. Then add them together.
Answer:
Look below.
Step-by-step explanation:
13.)
The lines are neither because the slopes are reciprocals.
14.)
The lines are perpendicular because the slopes are opposite reciprocals.
