At the circus, a clown is shot from a cannon. This situation can be modeled by the function: h = – 16t2 + 45t + 15, where 'h' is

weeeeeb [17]

Answer:

The maximum height is 46.64 feet.

Step-by-step explanation:

If we take the derivative of h whit respect to t and equal this to zero we would find the value of t which corresponds to the maximum h.

So, we have the function h(t):

$h(t)=-16t^{2} + 45t + 15$

Taking the derivative, we have:

$\frac{dh(t)}{dt}=-32t + 45=0$

Now, we solve it for t:

$t=\frac{45}{32}=1.4\: s$

Finally, we put this value of t into the original equation.

$h(t)=-16(1.4)^{2} + 45(1.4) + 15$

$h_{max}=46.64\: ft$

Therefore, the maximum height is 46.64 feet. All the given options are wrong, the one that comes closest is option A.

I hope it helps you!

Hana makes and sells knit scarves. She will charge $12 for each scarf she sells at the craft fair next week. She will pay a $25

Aleksandr-060686 [28]

Answer:

$12s - $25

Step-by-step explanation:

Given that:

Amount charged per scarve = $12

Cost of booth used = $25

Profit made for selling 's' scarve after paying for booth

Profit = Revenue - Expenditure

Revenue = cost per scarve * number of scarves sold

Revenue = $12 * s

Revenue = 12s

Expenditure = cost of booth

Expenditure = $25

Hence,

Profit made = $12s - $25
