Answer:
The answer is rotation 270° about the origin
Step-by-step explanation:
If (x , y) is a point in xy-coordinates
If the point rotate about the origin ⇒ (The positive direction is anti-clockwise)
1- 90°
Its image is (-y , x)
2- 180°
Its image is (-x , -y)
3- 270°
Its image is (y , -x)
If we assume A is (1 , 7)
1- ⇒ (-7 , 1) ⇒ rotation 90° about the origin
2- ⇒ (-1 , -7) ⇒ rotation 180° about the origin
3- ⇒ (7 , -1) ⇒ rotation 270° about the origin
∵ x-coordinate of point A small and +ve and y-coordinate large and +ve
∵ x-coordinate of point A' large and +ve and y-coordinate small and -ve
∴ The answer is rotation 270° about the origin
∴ The answer is rotation 270° about the origin

The circumference (perimeter) of the tire is 2 x π x r (radius= half of the diameter):
So one complete rotation is equivalent to the perimeter that is 2 x 13 x 3.1459
= 81.68 inches & if he competed 10 rotation that means he run for 10 x 81.68 ===> 816.8 In
Answer:
the worth of the house today is $392,000
Step-by-step explanation:
in 1995 --------- $200,000
and its appreciates by 4% yearly
so by 2019 the house will be
firstly we subtract 2019 from 1995 to know how many years the house has appreciated for
2019 - 1995 = 24years
therefore to get the total % the house has appreciated for we multiply the year by 4%
24 * 4% = 96%
so to get the appreciated value we multiply 96% by the initial amount of the house
96% * $200,000 = $192,000
therefore the worth of the house at present will be the initial amount plus the appreciated value
$200,000 + $192,000 = $392,000
