<u>Part A</u>
<u />
<u>Part B</u>
The vertex of the graph will be a maximum because the leading coefficient is negative.
The x coordinate of the vertex is 
.
When x=15/8, 
.
So, the vertex has coordinates 
<u>Part C</u>
Plot the two x-intercepts and the vertex and then draw a curve in the shape of a parabola passing through them.
The graph is in the attached image.
Answer:
10*40
80*5
20*20
Step-by-step explanation:
20*20=400
80*5=400
10*40=400
I believe the answer is b because u need to combine like terms and 6c+2c+5c is 13c.
I suppose you mean to have the entire numerator under the square root?
We can use a trigonometric substitution to start:
Then for 
, 
; for 
, 
. So the integral is equivalent to
We can write
so the integral becomes
