Answer:
last one
Step-by-step explanation:
You are swinging A(-1,-2) around the center which in this case is the origin. Keep in mind that points on a circle all have a equal distance from the origin. We don't want the distance from the center to change.
We want the center of that circle to be the origin.
So the answer is the last one:
"Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90° counterclockwise from point A. "
Answer:
y = 16
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 48 when x = 6, thus
k = 
= 
= 8
y = 8x ← equation of variation
When x = 2, then
y = 8 × 2 = 16
Divide 45.69 to 25 & y’all get 182.76
Find the area of the rectangle with the circles. Then find the area of each of the circles and add them together and minus that from the rectangle’s area.
A of rectangle = 30x10 = 300
A of circle = pi x r squared = pi x 25
A of shaded region = 300 - 75 pi = 68.3805cm square
Hello from MrBillDoesMath!
Answer:
k = 10
Discussion:
angle MYK = 180 and angle MYX = 180 => angle ZYX = 180 - 115 - 65
Trialing XYZ has 180 degrees so
180 = (4k + 5) + (6k+10) + 65 => combine like terms
180 = (4k + 6k) + (5 + 10 + 65) => as 4k +6k = 10k
180 = 10k + 80 => subtract 80 from both sides
180 -80 = 100 = 10k => divide both sides by 10
100/10 = k
Thank you,
MrB
