Answer: The scale factor of ABC to DEF is 5.

Step-by-step explanation:

Knowing that the side ratios are the same because the triangles are similar, you can use ratios to solve for x and y.

Side AB and Side DE are similar. The former has a length of 3 and the latter has a length of 15, which means that the triangle on the right is 5 times larger than the triangle on the left.

Using this information, you can solve for x by dividing 38.5 by 5.

X = 7.7.

You can then multiply 8 by 5 to solve for y, so y = 40.

X = 7.7, y = 40.

Scale factor is 5.

Find the equation of the line perpendicular to y= -2x+1 that also intersects the point (8, 2)

Kay [80]

The slope of the perpendicular is the negative reciprocal of the original line, so m = -1/(-2) = 1/2.

The general line of slope m through (a,b) is

$y - b = m(x-a)$

So the line we seek is

$y - 2 = \frac 1 2 ( x - 8)$

$y = \frac 1 2 x - 2$

Answer: y = 1/2 x + -2

Find the distance, c, between (–3, –4) and (1, 2) on the coordinate plane. Round to the nearest tenth.

Anon25 [30]

Answer
7.21
Step-by-step explanation:
Data :
(-3,-4) , (1,2)
Where
x₁ = -3 , x₂ = 1
y₁ = -4 , y₂ = 2
Formula for distance
D = √{(x₂-x₁)² + (y₂-y₁)²}
= √{(l--3)² + (2--4)²} = √(16+36) =√52 =7.21

alexandr402 [8]

The net force will be 3 N to the right.

12N - 8N = 4N - 7N= -3N. 3N is the net force to the right.
