Answer:
Option B
Step-by-step explanation:
we know that
The critical point of a function are the points on the graph of a function where the derivative is zero or the derivative does not exist.
we have
step 1
Take the derivative of the function
step 2
Set that derivative equal to 0 and solve for x. Each x value you find is known as a critical number
<em>Alternative Method</em>
The critical point of the quadratic equation is the vertex, because the function changes from decreasing to increasing at that point (In this problem the vertex is a minimum)
we have
Convert into vertex form
the vertex is the point (-2,-15)
therefore
The x-coordinate of the critical point is x=-2
P. S. The inequality sign changed or flipped when there's a negative figure involved.

It's the same as previous question
xz=xy+yz so 16.4=xz+3.5 so xz=16.4-3.5 =12.9
Answer:
5 MPH
Step-by-step explanation:
.5/.1 = 5
I converted it to decimals but this is the answer.
you just divide 1/2 by 1/10 to get the answer.
Answer: Mary is correct.
9/8 is an improper fraction, so we change it to 1 1/8.
Mary lives less than a mile from school, so we know that Thad lives farther since he lives a mile and 1/8 away, and Mary only lives 6/10 away, which is less than a mile.
Glad I could help, and good luck!
