Answer:

a)The sunglasses hit the ground at t=0 seconds

b)The maximum height h(t) = 1600feet

Step-by-step explanation:

Step(i):-

Given that the polynomial function

h(t) = -16 t² + 1600 ...(i)

Differentiating equation (i) with respective to 't' , we get

$\frac{dh}{dt} = -16(2t)+0$

Equating zero

$\frac{dh}{dt} = 0$

⇒ -32t =0

⇒ t =0

The sunglasses hit the ground at t=0 seconds

Step(ii):-

Again differentiating with respective to 't', we get

$\frac{d^{2} h}{dt^{2} } = -32(1) = -32$

The maximum height at t=0

h(t) = -16 t² + 1600

h(t) = 1600feet

Henry has 600 pokemon cards, he wants to sell them all for 100 dollars total, how much would it be for each pokemon card

LUCKY_DIMON [66]

Let's begin by listing out the information given to us:

number of cards = 600

Sale price = $100

Each pokemon card is worth:

$\begin{gathered} \frac{\text{Sale Price}}{Number\text{ of cards}}=\frac{100}{600}=0.167 \\ =0.17=17cents \end{gathered}$
