It got bigger, so the answer is 2 or 4
let's see the distance and see hw it compared
from the origin to the right side of the oriignal octogon, the distance is 2
from the origin to the right side of the new dialated octogon, the distance is 8
2 times what=8
divide both sides by 2
what=4
answer is 4
D is answer
Answer:
A
Step-by-step explanation:
e.g 10×1 = 10
10 + 8 = 18
10 × 2 = 20
20 + 8 = 28

Answer:</h3>
1. Solutions: x = 3.4, 10.6
2. Solutions: ,
3. Solutions: x = -1, 11
<h3>
Step-by-step explanation:</h3>
Quadratic formula:
Quadratic equation: ax² + bx c = 0, where a ≠ 0
1. x² - 14x + 36 = 0
a = 1, b = -14, c = 36
Substitute the given values into the formula:
Separate into two cases:
and
2. x² + 7x + 16 = 0
a = 1, b = 7, c = 16
Substitute the given values into the formula:
Imaginary number rule: For any positive real number "k",
Notes: Two imaginary solutions indicate that the graph will not intersect the x-axis. As a result, it has no real roots.
Separate into two cases:
3. x² - 10x - 11 = 0
a = 1, b = -10, c = -11
Substitute the given values into the formula:
Separate into two cases:
and

For this case we have that by definition of trigonometric relations of a rectangular triangle that, the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle.
That is to say:
We clear the length of the leg:
Answer:
Answer: 0.10289
FIRST WAY.
Step 1. Convert 10^3 into a whole number.
10^3 = 1000
Step 2. Divide 102.89 by 1000
102.89
-----------
1000
Answer: 0.10289
--------------------------------------------------------------------------------------------------------------
SECOND WAY.
To make it easier, you can move the decimal three times to the left. Which will give you the same answer. 0.10289
