3(k + 1) + 5k = -1 +5(k-1)
- 35
3k+3+5k= -1+5k-5-35
3k-5k+5k= -1-5-3-35
3k=-44
k= -14.6
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
This is combination problem since the order or arrangement matters. This is easily solvable with your scientific calculator. The formula would be nCr, where n is the total number of persons, and r is the number of persons in a group. So, using your calculator,
7C3 = 35
There can be 35 different groups.
Answer: Q = 124 and P = 29
Step-by-step explanation:
Triangles always = 180 degrees so do straight lines.
