The surface area is 15.

The area formula for a triangle is 1/2bh
The base of the surface is not given but it’s a parallelogram so opposite sides are congruent. The base would be 7 and the height would be 5.

7 x 5 = 30

you then divide it by half

SURFACE AREA = 15

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:

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

$r = 0 + 13 + 22$

$r = 35$

Which equation represents the polynomial function with zeros –3, 1, and 2, and a y-intercept of –12?

storchak [24]

To generate the equation we set up the factors
(x+3) * (x-1) * (x-2) which equals
x^2 + 2x -3 * (x-2)
x^3 +2x^2 -3x -2x^2 -4x +6 equals
x^3 -3x -4x +6 which equals

x^3 -7x +6
