A dilation has center (0,0). Find the image of the point L(-4,0) for the scale factor 9.
Andreyy89

Answer:

L' = (-36, 0)

Step-by-step explanation:

If the point (x, y) is dilated by a scale factor of k about the center (0, 0), then its image is the point (kx, ky)

∵ A dilation has a center (0, 0)

∵ The point L is (-4, 0)

∴ x = -4 and y = 0

∵ The scale factor of dilation is 9

∴ k = 9

→ By using the rule above

∵ kx = 9(-4) = -36

∵ ky = 9(0) = 0

∵ The image of the point L is (kx, ky)

∴ L' = (kx, ky)

∴ L' = (-36, 0)

Find the sum (the total measure) of the interior angles of a 17 sided polygon??
Lunna [17]

The formula in finding the sum or the total measure of the interior angles of polygon having n sides is:

Sum of interior angles = (n – 2) 180

Where n = number of sides of the polygon

In this problem, you are asked for the sum of the interior angles of a 17 sided polygon. You have to substitute the number of sides to the formula:

Sum of interior angles = (17 – 2) 180

Sum of interior angles = (15) 180

Sum of interior angles = 2,700 degrees

Round to the nearest hundredth?<br><br>A<br><br>4<br><br>?<br><br>35°<br><br>с<br><br>B
DaniilM [7]

The length of the unknown side length, |AB|, is 6.97

<h3>Trigonometry</h3>

From the question, we are to determine the value of the unknown side length

The unknown side length is the hypotenuse

Using SOH CAH TOA

We can write that

sin 35° = 4/|AB|

∴ |AB| = 4 /sin35°

|AB| = 4 /sin35°

|AB| = 6.97

Hence, the length of the unknown side length, |AB|, is 6.97
