<span>We can use a simple kinematic equation to find the velocity of the ball. v = v0 + at v = 58.5 m/s + (-9.80 m/s^2) (5.97 s) v = -0.006 m/s The negative sign means that the ball is heading down toward the ground. The small magnitude of the velocity means that the ball has reached the maximum height and is starting to fall back down toward the ground. The velocity of the ball is -0.006 m/s</span>

So use half the surface area formula: SA=2πr^2 and plug in what you already know
since you don't know the radius yet, solve for it using the circumference
C=2πr
514.96=3.14(2)r
82=r

SA=2π(82)^2
SA=6.28(6724)
SA=42,226.72
so your answer is 42,226.72 yards squared

10. The probability of a new york teenager owning a skateboard is 0. 37; of owning a bicycle is 0. 36 and of owning both is 0. 2
antoniya [11.8K]

The probability of the teenager owning a skateboard or a bicycle will be 0.46 or 46%. And the events are mutually exclusive.

<h3>What is the addition rule of size for two subsets?</h3>

For two subsets A and B of the universal set U, we have:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

The probability of a new york teenager owning a skateboard is 0.37, of owning a bicycle is 0.36, and of owning both is 0.27.

Then the probability of the teenager owning a skateboard or a bicycle will be

P(A ∪ B) = 0.37 + 0.36 - 0.27

P(A ∪ B) = 0.73 - 0.27

P(A ∪ B) = 0.46

Thus, the probability of the teenager owning a skateboard or a bicycle will be 0.46 or 46%.

The events are mutually exclusive.
