A smoke jumper jumps from a plane that is 1700 ft above the ground. The function y = -16t2 + 1700 gives the jumper's height y in

lakkis [162]

Answer: (A) 6.6 sec (B) 6.89 sec

Step-by-step explanation:

y = -16t² + 1700

1000 = -16t² + 1700

-1700 -1700

-700 = -16t²

÷-16 ÷-16

43.75 = t²

√43.75 = √t²

6.6 = t

***********************************

y = -16t² + 1700

940 = -16t² + 1700

-1700 -1700

-760 = -16t²

÷-16 ÷-16

47.5 = t²

√47.5 = √t²

6.89 = t

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
