Determine the equation of the line satisfying the following condition. Containing the point (-1,-5) and parallel to 3x+2y=9

y=-3/2x-13/2

Step-by-step explanation:

To find a line parallel to the given line, we know that the two equations must have the same slope. We first want to find the slope of the given equation.

3x+2y=9             [subtract both sides by 3x]

2y=-3x+9            [divide both sides by 2]

y=-3/2x+9/2

Now, we know the slope if -3/2. All we have to do is plug in the given point to find the y-intercept.

-5=-3/2(-1)+b      [multiply]

-5=3/2+b            [subtract both sides by 3/2]

b=-13/2

Now, we know the equation is y=-3/2x-13/2.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
