We have to calculate the x- component of vector v = 250 m/s.
α = 30° ( above the x-axis ):
v x = v · cos α
v x = 250 m/s · √3/2 = 250 m/s · 0.866 = 216.5 m/s
Answer:
v x = 216.5 m/s
Hi there!
The formula for the perimeter of a rectangle is P = 2 (l + w).
We can simplify this formula so that we can find the solutions easier.
P = 40
40 = 2 (l + w)
divide both sides by 2
40/2 = l + w
20 = l + w
So the length + width has to equal to 20.
So your answers would be B , C , D.
Hope this helped! :)
Step-by-step explanation:
r - 18 = 27
r = 27 + 18
r = 45

The GCF of 21 and 15 is 3. The are no variables in common so the factor =
3(7x -5y)
