Answer:

After 1.5 second of throwing the ball will reach a maximum height of 44 ft.

Step-by-step explanation:

The height in feet of a ball after t seconds of throwing is given by the function  

h = - 16t² + 48t + 8 .......... (1)

Now, condition for maximum height is  

\frac{dh}{dt} = 0 = - 32t + 48 {Differentiating equation (1) with respect to t}

⇒ t = \frac{48}{32} = 1.5 seconds.

Now, from equation (1) we get

h(max) = - 16(1.5)² + 48(1.5) + 8 = 44 ft.

Therefore, after 1.5 seconds of throwing the ball will reach a maximum height of 44 ft. (Answer)

Cadie is going to toss three coins simultaneously. What is the probability that exactly two of the coins will land on heads?
Contact [7]

For each coin, there are <u>2 outcomes</u>, heads (H) or tails (T), so for the <u>3 coins</u>, the number of outcomes are:

2 x 2 x 2 = <u>8 outcomes:</u>

HHH / HHT / HTH / THH / TTT / TTH / THT / HTT

Out of all these outcomes, there are <u>3 ways</u>, we get exactly 2 Heads:

HHT / HTH / THH

So, the probability of exactly 2 coins landing on Heads is 3/8, or 0.375
