Answer:
242.
Step-by-step explanation:
C = 0.03 x 2 − 8 x + 700
When the marginal cost = $522 we have:
522 = 0.03 x 2 − 8 x + 700
0.03x^2 - 8x + 700 - 522 = 0
0.03x^2 - 8x + 178 = 0
Using the quadratic formula:
x = [ -(-8) +/- sqrt( 64 - 4 * 0.03 * 178)] / 0.06
= 8 +/- sqrt42.64 / 0.06
= 242 players.
ANSWER
D. Ellipse;
EXPLANATION
The given equation is
Dividing through by 9 gives
This is the equation of an ellipse centered at the origin.
If this ellipse has been translated, so that its center is now at (-1,3), then the equation of the translated ellipse becomes
We multiply through by 9 to get,
Expand to obtain;
Expand to obtain;
Regroup and equate to zero to obtain;
Since the area is 120 ft^2, and we know the length of the room is 15 ft, we can calculate the width.
120/15 = 8
To find the perimeter, we use the following formula
2l + 2w = P
2 (15) + 2 (8) = 46 ft
Answer:
No because the chairs would have to be the price of $62.00
Step-by-step explanation:
divide 558 by 9
so if the chairs had been 62 dollars then he would have enough
