What is the scale factor from polygon A to polygon B?

Mathematics

Arada [10]3 years ago

You must divide the larger by the smaller... That will give you the scale factor.

For example: Rectangles 10 x 20 and 5 x 10

the scale factor us 10/5 = 20/10 = 2

Hope this helps.

Which graph correctly represents the equation y=−4x−3?
pentagon [3]

Idk if u got the answer or not, but It's the last graph. Just by looking at it you can point two things out.

1. The y intercept is -3 (so the graph needs to have the point (0,-3) that takes out two options.)

2. The slope is negative. (Which means the graph is going to decrease. So that takes out the other two options that have it increased.)

Find the value of y. <br> Answer options: 62, 66, 70, 74
Pie

Answer:

The value of y = 70°

Step-by-step explanation:

∵ The measure of the major arc = 160 + 60 = 220°

∵ The measure of the circle is 360°

∴ The measure of the minor arc = 360 - 220 = 140°

∵ y is the angle between a chord and a tangent

∵ The chord subtended by the arc of measure 140°

∵ y is subtended by the arc of measure 140°

∵ Angle of tangent subtended by an arc,

  its measure = half the measure of the subtended arc

∴ The measure of y = 1/2 the measure of the subtended arc

∴ y = 1/2 × 140 = 70°

Help ASAP!!What is the volume of our planet if we assume that it is a sphere with the radius 3, 950miles? Round your answer to t
zloy xaker [14]

Answer: 258023743333miles³

Step-by-step explanation:

Volume of a sphere = 4/3πr³.

where,

π = 3.14

r = radius = 3950

Volume of a sphere = 4/3πr³.

= 4/3 × 3.14 × 3950³

= 4/3 × 3.14 × 61629875000

= 258023743333miles³

The volume of our planet if we assume that it is a sphere with the radius 3,950miles will be 258023743333miles³
