Answer:
First one equals -15
Second one equals -3
Step-by-step explanation:
(-4)*2 - 7
= (-8) - 7
= (-15)
(-4) + 1
= (-3)
Hopefully this helps.
Answer:
20736
Step-by-step explanation:
xy^4 = z
x=4 , y=3
(4*3)^4=z
12^4=z
z=20736
Those are opposite angles and opposite angles are equal to one another.
so we can say that 62 = 2 + 3x and solve x from there.
60 = 3x
x = 20
Answer:
F = 100(.5736)
= 57.36 lbs. (rounded off to 2 decimal places)
2) sin60 = .866
F = 18(.866)
= 15.59 lbs. (rounded off to 2 decimal places)
Step-by-step explanation:
F = friction
