Step-by-step explanation:
h = -16t² + 10t + 6
When h = 0, -16t² + 10t + 6 = 0.
=> -8t² + 5t + 3 = 0
=> (-8t - 3)(t - 1) = 0
=> t = 1 or t = -3/8 (rejected as time cannot be negative)
Hence 1 second passed before the ball hits the ground.
Step-by-step explanation:
according to the drawing,
that is an Obtuse triangle (C)
Answer:
c-60/100
Step-by-step explanation:
6x10=60
10x10=100
making 60/100
or the other way round 60÷10=6 100÷10=10
Answer:
2 two-point shots, 1 free throw
Step-by-step explanation:
If each two-point shot is worth two points, then she could have scored two of them, which would make five points. She couldn't have scored any more two-point shots, because then the number would be over 5. However, after scoring 2 two-point shots, there is still one point left, so she must have scored 1 free throw to get that point.
Use the identity sin 2x = 2 sin x cos x.
Then sin 2x + √3cos x = 2 sin x cos x + √3cos x.
We can factor cos x out of both sides:
(cos x)(2sin x + √3)
