For this case we have the following quadratic functions:
Revenue: 
Cost: 
Then, we observe that the profit is given by the following mathematical relationship:

Substituting values we have:

Making the corresponding calculations we have:

Answer:
An expression that represents the profit is:

<span>common difference for the sequence = 1/16
cause
1/4 = 4/16
and
3/8 = 6/16
so
4/16 + 1/16 = 5/16
5/16 + 1/16 = 6/16

1. C
L=1/2(Pxl)
L=1/2(20x9)
L=1/2(180)
L=90
SA=1/2(Pxl)+B
SA=90+5^2
SA=115
B, A, C, B.
Answer:
(-4, 7)
Step-by-step explanation:
It would be the exact opposite of point R because it was rotated about 180 degrees from it's original location
If it is discounted 25%, then u r actually paying 75%
0.75(119) = 89.25 (without tax)
sales tax = 7 1/2% = 7.5% = 0.075
89.25(1.075) = $ 95.94 <===
