Answers
Answer:
a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 2
Step-by-step explanation:
At Image I, we have vertex at point (3,-2), and the length of the left side is of 1 unit(from -2 to -3).
In the larger figure, this length is of 2 units, so the dilation has a scale factor of 2 units. The rotation, due to the coordinates changing, is of 90º counterclockwise(if it was across the x-axis, only the y coordinate would change, but on image II, both coordinates change).
So the correct answer is:
a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 2

Consider the complementary angles shown below. Find the value of x. X + 4 3x + 2
Answers
Answer:
x = 21
Step-by-step explanation:
For the complementary angles, the sum of two angles is equal to 90 degrees.
ATQ,
3x+2+x+4 = 90
Taking like terms together,
3x+x+6=90
4x+6=90
4x = 84
x = 21
So, the value of x is equal to 21.

( y - 10 )( y - 2 )
Explanation:
First break down the equation y^2 -12y +20.
The equation now becomes y^2 -2y -10y +20. This is called creating and using the sum-product pattern. Now you need to find the common factor between both pairs to simplify the next equation, y ( y - 2 ) - 10 ( y- 2 ). ( y - 2 ) is the common factor. Now all you do is rewrite your equation in factored form. In this case, ( y - 10 )( y - 2 ). Comes out to be your answer.

The base of a right prism is a regular hexagon with side 4. The height of the prism is 6. Find the lateral area and volume.
Answers
Answer:
(i) The lateral area of the right prism is 144 square units
(ii) The volume of the right prism is 249.42 cubic units.
Step-by-step explanation:
The lateral area of the right prism is calculated as;
Lateral area = perimeter of the base x height
Given;
a side of the hexagon base, s = 4
height of the prism = 6
perimeter of the hexagon = 6s
Lateral area = (6 x 4) x 6
Lateral area = 144 square units
Volume of the right prism is calculated as;
V = base area x height
base area of a hexagon = [tex]\frac{3\sqrt{3} \ \times \ s^2}{2}[/tex]
Volume of the right prism = [tex]\frac{3\sqrt{3} \ \times \ s^2}{2} \ \ \times \ \ h\\\\[/tex]
[tex]V = \frac{3\sqrt{3} \ \times \ (4)^2}{2} \ \ \times \ \ 6\\\\V = 249.42 \ cubic \ units[/tex]

What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
On a scale drawing of an office space floor plan, 1 inch represents 3 feet. Then the scale factor is given as,
Scale factor = 3 / 1
Scale factor = 3 feet per inches
The length of the copier room measures 7 inches. Then the number of feet that represents 7 inches is given as,
⇒ 7 x 3
⇒ 21 feet
The number of feet that represents the length of the copier room measures 7 inches on the floor plan will be 21 feet.

y=5x−10.
Explanation:
The slope of a line passing through the two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.
We have that x1=3, y1=5, x2=2, y2=0.
Plug the given values into the formula for slope: m=(0)−(5)(2)−(3)=−5−1=5.
Now, the y-intercept is b=y1−m⋅x1 (or b=y2−m⋅x2, the result is the same).
b=5−(5)⋅(3)=−10.
Finally, the equation of the line can be written in the form y=mx+b.
y=5x−10.
Answer:
The slope of the line is m=5.
The equation of the line in the slope-intercept form is y=5x−10.
The equation of the line in the point-slope form is y−5=5(x−3).
The equation of the line in the point-slope form is y=5(x−2).
The general equation of the line is 5x−y−10=0.
