Answer:
$1770 for 25 hours
Step-by-step explanation:
600 × 225 = 135000
135000 ÷ 90 = 1500 min
1500min=25 hours
$2.95×600= $1770
Find critical points by setting derivative equal to 0.
Derivative of polynomial is found by multiplying coefficient by exponent, then subtracting 1 from exponent.
f'(x) = 5x^4 - 30x^2 + 9 = 0
This is in quadratic form, use quadratic formula to find x^2
The graph of the function is line A
Answer:
The answer is
<h3>the last graph</h3>
Step-by-step explanation:
To find the graph which shows (f + g)(x) we must first find (f + g)(x)
That's
f(x) = - x² + 3x + 5
g(x) = x² + 2x
To find (f + g)(x) add g(x) to f(x)
That's
(f + g)(x) = -x² + 3x + 5 + x² + 2x
Group like terms
(f + g)(x) = - x² + x² + 3x + 2x + 5
We have (f + g)(x) as
(f + g)(x) = 5x + 5
Since (f + g)(x) is linear the graph which shows (f + g)(x) is <u>the last graph</u>
