Consider an object that's not moving, like a chair at rest on the floor. There are two forces acting on it:

• its own weight, pulling it downward

• the normal force, i.e. the floor pushing upward on the chair.

Both of these forces are non-vanishing, but the net force is 0, so the chair remains at rest and its velocity stays at 0.

Y = 15 when x = 60, find y when x = 45

Ne4ueva [31]

Should be 11.25 because 15 is 1/4 of 60 . U take 1/4 away from 60 so u gotta take 1/4 away from 15 which is 3.75 . And you get 11.25

Andrey is making a garden box and wants to know how much dirt is needed to fill the box. A prism has a length of 8 feet, height

olga_2 [115]

Answer:

The space inside the box is the volume, which is 128 ft3

Step-by-step explanation:

Given the dimensions of the box as 8ft by 2ft by 8ft. We calculate it's volume and surface area to validate the statements;

$V=lwh\\\\=8\times 2\times 8\\\\=128 \ ft^3\\\\Area=2lw+2lh+2hw\\\\=2(8*2)+2(8*8)+2(2*8)\\\\=192 \ ft^2$

The volume of the box is 128 ft^3 and its surface area 192 ft^2. Hence, the correct statement is The space inside the box is the volume, which is 128 ft3

Write an equation of the line that passes through (-4,-1) and is perpendicular to the line y=4/3x+6

Sonja [21]

Answer:

$y=-\dfrac{3}{4}x-4.$

Step-by-step explanation:

If needed line is perpendicular to the line $y=\dfrac{4}{3}x+6,$ then its slope satisfies condition

$m\cdot \dfrac{4}{3}=-1\Rightarrow m=-\dfrac{3}{4}.$

Then the equation of needed line will have look

$y=-\dfrac{3}{4}x+b.$

Since this line passes through the point (-4,-1), then

$-1=-\dfrac{3}{4}\cdot (-4)+b,\\ \\-1=3+b,\\ \\b=-1-3=-4.$

Hence, the equation is

$y=-\dfrac{3}{4}x-4.$
