Answer:

y = -4x+2

Step-by-step explanation:

We have 2 points (1,-2) and (4,-14)

We can find the slope using

m = (y2-y1)/(x2-x1)

= (-14--2)/(4-1)

= (-14+2) / (4-1)

= -12/3

= -4

We can use point slope form to write an equation

y-y1 = m(x-x1)

y--2 = -4(x-1)

Distribute the -4

y+2 = -4x+4

Subtract 2 from each side

y+2-2 =-4x +4-2

y = -4x+2

This is in slope intercept form ( y= mx+b) where the slope is -4 and the y intercept is 2

M<GFN = 4x+10, m<NFE = 14x + 3, and m<3GFE = 157°. find m<NFE

pantera1 [17]

Answer:

115

Step-by-step explanation:

set up the equation to find x:

GFN+NFG=GFE

(4x+10)+(14x+3)=157

calculate for x

you'll get x=8

put 8 into NFE

14(8)+3=115

Kristen lives directly east of the park. The football field is directly south of the park. The library sits on the line formed b

klemol [59]

Imagine right triangle PHF, where P - park, H - home and F - football field, then PH, PF are legs and HF is hypotenuse . Denote point L to be library. You know that point L lies on the segment FH and FL=8, LH=2. Also you know that PL is an altitude to the hypotenuse.

Use the property of altitude drawn from the vertex of right angle to the hypotenuse (the length of the altitude is geometrical mean between legs' projections onto hypotenuse):

$PL=\sqrt{HL\cdot LF},\\ PL=\sqrt{2\cdot 8}=\sqrt{16} =4$ mi.

This means that the distance between park and libriry is 4 miles.

Consider right triangle PLF ( angle L is right angle and PF - hypotenuse). By the Pythagorean theorem,

$PF^2=PL^2+LF^2,\\ PF^2=4^2+8^2,\\ PF^2=16+64=80,\\ PF=\sqrt{80} =4\sqrt{5}$ mi. The distance between park and football field is $4\sqrt{5}$ miles.

Answer: the distance between park and libriry is 4 miles and the distance between park and football field is $4\sqrt{5}$ miles.

A cube is a rectangular prism whose edge lengths are congruent. What is the volume of a cube with an edge length of 2 feet?

leonid [27]

Think about it. The area (the two dimensional version of volume) of a two dimensional shape, like a square, can be 2 feet by two feet. Multiply these together, and you get 4 feet^2, or four feet squared, This is because in order to get the volume, you multiply the base times the height, one side by the other. You make the feet "feet squared" because you are also multiplying the measurements together, too. In three dimensional shapes though, you have three different ways to go. You have the base, the height and the width beyond it. So you multiply them together and get 8 feet^3 or 8 feet cubed (you multiply three measurements together).
