Answer:

<em>4</em>

Step-by-step explanation:

The solid triangle dilated to become the dashed triangle.

Compare two corresponding sides. For example, the vertical side of the solid triangle measures 3 units. The vertical side of the dashed triangle measures 12 units. 12/3 = 4. The dilation is 4. The scale factor is 4.

Answer:

Scale factor: 4

Step-by-step explanation:

Let m be scale factor.

We have been given two triangles such that dashed triangle is image of the pre-image solid triangle.

First of all, we will find length of bases of both triangles by counting the units.

Base of pre-image: 2 units.

Base of image: 3-(-5)=3+5=8 units.

We know that after multiplying a side of pre-image by scale factor, we get image.

2\cdot m=8

\frac{2\cdot m}{2}=\frac{8}{2}

m=4

Therefore, the scale factor for given diagram is 4.

An angle measures 130° less than the measure of its supplementary angle. What is the measure of each angle?
seropon [69]

Answer:

Angle one is 130 degrees and angle two is 50 degrees

Step-by-step explanation:

You can get this answer by knowing that supplementary angles equal 180 degrees in total. So if one angle is 130 degrees less you take that and subtract it from 180 to get 50 degrees as the second angle.

Min knows that Pi times r = 9.42 centimeters. What would she need to do to find the area?
VLD [36.1K]

Answer:

She could divide 9.42 by Pi to find the radius, then multiply 9.42 by the radius.

(Last option)

Step-by-step explanation:

We need the formula for the area of a circle:

A = πr²

Remember r² = r × r

So you could rewrite the formula like this:

A = π × r × r

If π × r = 9.42, then the area becomes:

A = 9.42 × r

"<em>Then multiply 9.42 by the radius</em>".

To find "r", divide 9.42 by π.

π × r = 9.42

r = 9.42/π

"<em>Divide 9.42 by Pi to find the radius</em>".

F(x) = 3* + 10xand g(x) = 5x - 3, find (f - g) (x)
melisa1 [442]

Answer:

(f-g)(x)= (3x + 10) - (5x -3)

f-g = 3x + 10 - 5x + 3

f-g = -2x + 13
