Answer: The answer is 80 mph.
Step-by-step explanation: 1. Divide 14 from 571.
2. You'll get the answer 40. So it's 40 mph.
3. If she's trying to shorten by 1/2 then she should drive 80 mph because if you drive 80 mph it will take 7 hours instead of 14 hours. (She'll go 7 hours because you divide 14 hours by 2. Then you have to multiply 2 to 40.)
Answer:
5)
<2 = 79°
<1 = 101°
<3 = 101°
6)
x = 5
y = 3
Step-by-step explanation:
5)
<2 = 79°
<1 = <3 = 180 - 79 = 101°
6)
4y - 6 = 2y
2y = 6
y = 3
2x + 4 = x + 9
x = 5

Answer:
C. 10 units
Step-by-step explanation:
The distance MN can be found using the distance formula.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((2 -(-4))² +(3 -(-5))²) = √(6² +8²) = √100 = 10
The distance from M to N is 10 units.
Answer:
63568 dollars
Step-by-step explanation:
Given that in your computer store you charge $1012 per computer sold. Your costs are given by the equation
where x is the number of computers sold.
Revenue = sales price *no of computers sold
= 1012x
Profit = Revenue - cost
=
Use derivative test to find maximum profit
Equate I derivative to 0
x= 128
i.e. if 128 computers are manufactured and sold profit wouldbemaximum
Profit maximum=
