For this case we have the following equation:
w = || F || • || PQ || costheta
Where,
|| F ||: force vector module
|| PQ ||: distance module
costheta: cosine of the angle between the force vector and the distance vector.
Substituting values:
w = (60) * (100) * (cos (45))
w = 4242.640687 lb.ft
Answer:
The work done pushing the lawn mower is:
w = 4242.640687 lb.ft
Answer:
x - 9 = 19 x = 28
8y -5x = 16 idk but what i do know is this...
Step-by-step explanation:
8 x 5 - 5 x 5 = 15 & 8 x 4 - 5 x 3 = 17
so if u want to try to put in some numbers u might find it.
but it would be better if i had answer choices.
ANSWER: A & B
Reason: the lines are the same criss cross
Answer:
The last set cannot be the angles of a triangle
Step-by-step explanation: 61+61+59= 181. The angles of a triangle must always total 180°
All the other combinations meet that requirement.
