A. Use the center of rotation point C and roatate point P clockwise around it 90°. The image is P'.
What is the coordinate of P'?
P'=( _ , _ )
B. With center of rotation point C and roatate point P' clockwise around it 90°. The image is P''.
What is the coordinate of P''?
P''=( _ , _ )
Answers
Answer:
A. P' = (9, -2)
B. P" = (1, -4)
Step-by-step explanation:
To make it easier to understand, make point C the origin (0 , 0). From that, you will notice point P is 3 units right and 5 units up of point C, meaning the coordinates of point P is (3, 5). A 90° rotation clockwise on point P (3, 5) is (5, -3). Since point C is 4 units right and 1 unit up from the actual origin, we will add that to (5,-3); (5 + 4, -3 + 1) = (9, -2). Therefore, P' = (9, -2).
Knowing the coordinates of P' allows us to figure out the coordinates of P''. Once again, we'll make point C the origin, meaning P' would be at (5, -3). Like we did before, we will perform a 90° rotation clockwise of (5, -3) to get (-3, -5). Lastly, add back the appropriate amount of units to (-3, -5) to make point C the center of rotation in this example; (-3 + 4, -5 + 1) = (1, -4). Therefore, P" = (1, -4).

What is a quotient?A quotient is a quantity that is obtained by dividing two integers. The quotient is a term that is widely used in mathematics to refer to the integer component of a division, as well as a fraction or a ratio.

Answers
Answer:
angle 1 = 50°
angle 2 = 70°
angle 3 = 50°
Step-by-step explanation:
We know the top triangle equals 180 degrees.
angle 1 + 60 + 70 = 180
angle 1 + 130 = 180
angle 1 = 50
Because of parallel lines, we know that opposite angles will be equal.
What I mean by this is that angle 1 = angle 3 and angle 2 = 70 degrees.
angle 1 = 50°
angle 2 = 70°
angle 3 = 50°

Answers
Answer:
The slope is 5 and the slope or y intercept is 8 and the equation is y = -5x + 8.
Step-by-step explanation:
Turn it into -2y = 10x + 16
Then divide by -2
y=-5x+8
The slope is 5 and the slope or y intercept is 8 and the equation is y = -5x + 8.
Answer: y = 5x + 8
Step-by-step explanation:
-10x - 2y = 16 —> add 10x to each side
2y = 16 - (-10x) —> add the opposite & flip the numbers so the variable is closest to the equal sign
2y = 10x + 16 —> divide 2 by each side
y = 10x/2 + 16/2 —> simplify
y = 5x + 8
Harley and Natalie are each given 2 1/3 kg of clay Harley makes as many balls of clay as he can from his clay. Each ball weighs 1/6 kg. Natalie makes ten more clay balls than Harley (each weighing the same).
If Natalie used up all her clay, how much does each of her clay balls weigh?
Answers
Solution:
Note that:
One ball made by Harley = 1/6 kgEach student was given 2 1/3 kg of clayNatalie made 10 more balls (same weight) than Harley.Solving for how much balls made by Harley.
7/3 ÷ 1/6=> 7/3 x 6=> 7 x 2=> 14 balls.Solving for how much balls made by Natalie.
14 + 10 => 24 ballsFinding out the weight of each ball made by Natalie.
7/3 ÷ x = 24=> 7/3 × 1/x = 24=> 7/3x = 24=> 7 = 72x=> x = 7/72 kgNatalie's balls weigh about 7/72 kg.

Hence, section PL measures about 18.03 cm in length (rounded to the nearest hundredth digit).
what is length ?The length of a one-dimensional object, such as a line, curve, or straight segment, is measured by the fundamental physical quantity known as length. It is a way to gauge the separation between two points or the size of an object along a specific axis. The International System of Units (SI) uses metres as the unit of length (m). One of the most important ideas in geometry is length, which is used to describe the characteristics of geometric forms and shapes. For instance, the length of a circle is the distance around its circumference, whereas the length of a line segment is the distance between its endpoints.
given
(A) We must first determine the length of chord PQ in order to determine the length of segment PM. Since LM is the perpendicular bisector of PQ in the figure, PM is equal to MQ. PQ's length is 20 cm, so PM and MQ's lengths are each 50 percent of that, or:
PM=MQ=20/2=10 cm
Sqrt(PM2 + LM2) = PL
(d) When we enter the values from parts (a) and (c), we obtain:
Sqrt(10 + 15) = PL
Sqrt(100 + 225) = PL
Sqrt = PL (325)
PL ≈ 18.03 cm
Hence, section PL measures about 18.03 cm in length (rounded to the nearest hundredth digit).
