The rate at which sand is poured into a bag is modeled by the function r given by r(t)=15t−2t2, where r(t) is measured in millil

balu736 [363]

Answer:

35 mililiters

Step-by-step explanation:

Given

$r(t) = 15t - 2t^2$

Required

Accumulated amount from t = 0 to 2

This implies that, we substitute the values of t from 0 to 2 in the function

$r(0) = 15*0 - 2*0^2= 0$

$r(1) = 15*1 - 2*1^2= 13$

$r(2) = 15*2 - 2*2^2= 22$

The accumulated sand (r) is:

$t = r(0) + r(1) + r(2)$

$r = 0 + 13 + 22$

$r = 35$

The government taxes a manufacturer $0.20 for a bottle of soda. The manufacturer raises the wholesale price an additional $0.60

alukav5142 [94]

Answer: $0.95

Step-by-step explanation:

Hi, to answer this question we simply have to add all amounts raised by the government, the manufacturer, and the retailer.

Mathematically speaking:

$0.20+$0.60+$0.15 = $0.95

So, a consumer pays $0.95 more per bottle of soda.
