Step-by-step explanation:
<h3>
7×13=11U </h3><h3>
making U subject of formula you have </h3><h3>
91= 11U </h3><h2>
therefore U = 91/11= 8.97 </h2>
Answer:
(3*12) 36 Camcorders= $5040
1 Camcorder= $5040/36 = $140
Original= $140/1.03= $135.92
Answer:
Step-by-step explanation:
Let us assume that she makes 10 minutes of call.
Telecorp has a flat rate of 7 cents per minute. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.07 × 10 = $0.7
America's charges 25cents per call. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is $0.25
Phone busters charges 35 cents per call and 2 cents per min. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.35 + 10 × 0.02
= 0.35 + 0.2
= $0.55
The cheapest service is that of America's. Therefore, she should choose it.
Answer:
its the second one y=870x-5300
Step-by-step explanation:
Line: y = -1/2x + 4 area: is 7/3 you'll have to find the slope of the tangent line first which is: y' = 2x - 2 = 2(2) - 2 = 2 the perpendicular slope is then -1/2 y - 3 = -1/2(x - 2) y = -1/2x + 4
then you integrate, by using the line as the upper area, then subtracting the lower area parabola between 0 and 2 int(-1/2x + 4 - (x^2 - 2x + 3)) = -1/4x^2 + 4x -x^3/3 + x^2 - 3x replace 2 for x and you will get -1 + 8 - 8/3 + 4 - 6 12 - 29/3 = 7/3
