Answer:
60% off
Step-by-step explanation:
Let's try both.
1. 550 off =
935.11 - 550 = $385.11
2. 60% off =
935.11 - (.60*935.11) = $374.04
$385.11 > $374.04, so she should use the 60% off coupon.
Answer:
The slope of the line is -1/4
Step-by-step explanation:
To find the slope, we use the formula
m = (y2-y1)/(x2-x1)
We have the points (-3,2) and (5,0)
= (0-2)/(5--3)
= (-2)/(5+3)
=-2/8
= -1/4
The slope of the line is -1/4
If the mower is pulled over a flat horizontal surface, then first get the component of the force in the direction of the mower's displacement:
(120 N) cos(30°) = 60 √3 N ≈ 103.923 N
Then the work done by the boy on the mower over a distance of 12.8 m is
(103.923 N) (12.8 m) ≈ 1330.2 Nm ≈ 1330 J
