What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

A'B'C'D' E' is the image of pentagon ABCDE under a dilation with a scale factor of 1/2.

We need to find the length of C'D'.

Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.

A dilation is a transformation which preserves the shape and orientation of the figure, but changes its size.

The Length of segment CD is units.

Length of segment A'E' = 5/2 × Length of segment AE

Therefore;

Length of segment C'D' = 1/2 ×2 = 1 units.

Hence, the  length of segment C'D' is 1 unit.

A radioactive substance decays at a rate of 3.4% per day. If it starts at 200 grams, how
many days will it take for the substance to decay to less than 150 grams?

Answers

Answer: 9

Step-by-step explanation:

Since the percent is decaying, you subtract 3.4 from 100, which gets you 96.6

200(0.966)^9 gets you 146.5 which is less than 150

Hey there!

The answer to your question is 3480

There are two ways we can do this. I will show you both, so you know how to do it in the future:

The First Way ~ Parantheses First:

Step 1.) Add [tex]86[/tex] and [tex]34[/tex]

[tex]29(120)[/tex]

Step 2.) Multiply

[tex]3480[/tex]

The Second Way ~ Distribute First

Step 1.) Multiply [tex]29[/tex] and [tex]86[/tex]

[tex]29(34)+2494[/tex]

Step 2.) Multiply [tex]29[/tex] and [tex]34[/tex]

Simplify the inequality:
-12.4x+8x > -0.4x-5.2-2.7

Answers

Answer:

x < 1.975

Explanation:

-12.4x + 8x > -0.4x - 5.2 - 2.7

Add similar elements: -12.4x + 8x = -4.4x

-4.4x > -0.4x - 5.2 - 2.7

Subtract -5.2 - 2.7: -7.9

-4.4x > -0.4x - 7.9

Multiply both sides by 10

-4.4x · 10 > -0.4x - 7.9 · 10

Refine

-44x > -4x - 79

Add 4x to both sides

-44x + 4x > -4x - 79 + 4x

Simplify

-40x > -79

Multiply both sides by -1 (Reverse the inequality)

-40x (-1) > -79 (-1)

Simplify

40x < 79

Divide both sides by 40

40x / 40 < 79 / 40

Simplify

x < ⁷⁹⁄₄₀

Turn the fraction into a decimal

x < 1.975
