If the center of dilation is at the origin, by what scale factor was octagon ABCDEFGH dilated?
A.) 1/2
B.) 1/4
C.) 2
D.) 4
Answers
C. 4
Look at where segment A'B' intersects, at x = 8.
Look at where segment AB intersects, at x = 2.
AB is smaller then A'B' that means the scale factor is
[tex]A'B'/AB=\frac{8}{2}=4[/tex].
Hope this helps.

have a great day
Answer:
x = 6
Step-by-step explanation:
According to the question, Suppose x is the number.
multiplying x by 3 and adding 4, you get 22.
3x + 4 = 22
Solving,
3x + 4 = 22
3x = 22 - 4
3x = 18
x = 18/3
x = 6

for positive acute angles A and B, it is known that cos A= 5/13 and sin B=12/37. find the value of cos (A+B) in simplest form
Answers
Using trigonometric identity, the value of cos (A + B) in the simplest form is 31 / 481.
How to use trigonometric identity?Cos(A + B) = Cos A Cos B - Sin A Sin B.
Using trigonometric ratios,
sin B = opposite / hypotenuse
Cos A = adjacent / hypotenuse
cos A = 5 / 13
sin B = 12/37
Using Pythagoras theorem,
13² - 5² = b²
b = √144
b = 12
37² - 12² = a²
a = √ 1225
a = 35
Therefore,
Cos(A + B) = Cos A Cos B - Sin A Sin B.
cos A = 5 / 13
sin A = 12 / 13
sin B = 12 / 37
cos B = 35 / 37
Hence,
Cos(A + B) = 5 / 13 × 35 / 37 - 12 / 13 × 12 / 37
Cos(A + B) = 175 / 481 - 144 / 481
Cos(A + B) = 31 / 481

3. what is the slope intercept form?
4. In the equation y=-2x+6 identify the slope and the y- intercept.
5. What is the slope and equation of a horizontal line? A vertical line?
Answers
1. In algebra, a function is an equation that has only one answer for y for every x present.
2. The set (3,4) (4,5) (5,6) and (6,7), represents a function because when graphed, it forms a diagonal line. The second set of coordinates forms a non-linear "line." Furthermore, a way to test if something is a function or not is through the VERTICAL LINE TEST. If a vertical line can pass through the graphed line without touching it in two places at once, then it's a function. Vertical lines automatically fail this test; the second set of ordered pairs creates a vertical line.
3. The slope-intercept form of the correct line is y = 3/3x + 1. (y = mx + b)
4. The slope is -2 and the y-intercept is 6.
5. A horizontal line has a slope of 0 (Zero Slope) because it doesn't slope! A vertical line has an undefined slope because... it does.

A triangle with sides 9, 12 and 15 is similar to a triangle whose longest side is 25. Find the perimeter of the larger triangle.
Answers
Answer:
P = 60
Step-by-step explanation:
First, to find the scale factor, or how much bigger the other shape is, you can do so by comparing the two triangles' longest sides.
25 5
---- = ----
15 3
So the larger triangle is 5/3 times bigger.
This means that all of its other sides with also be 5/3 times bigger.
So:
9 (5/3) = 45/3 = 15
12 (5/3) = 60/3 = 20
25 + 15 + 20 = 60
So the perimeter is 60.
You could have also found the perimeter of the smaller triangle, 9 + 12 + 15 = 36, then multiplied it by the scale factor, which would be:
36 (5/3) = 180/3 = 60
You would get the same thing.
In what place value will the first digit of the quotient be for 5.64 divided 15.
