Answer:
(x-0)^2-(y+1)^2=153
Step-by-step explanation:
Find midpoint by averaging x-value and y-values
Midpoint: (0, -1)
Find radius by calculating distance from center to a point on the diameter.
Radius: 12.369
Use circle formula: (x-h)^2+(y-k)^2=r^2
Hint: (h,k) is the center
Answer: (x-0)^2-(y+1)^2=153
Lateral Surface Area. The general formula for the total surface area of a right prism is T . S . A . = p h + 2 B where represents the perimeter of the base, the height of the prism and the area of the base.
The topic/ search query is "intercepted arcs"
The outermost angel is your far arc (135°)
The closer of the two on the circle is your near arc (missing variable "x")
The angle provided is your reference angle (39°<span>)
</span>The formula used to solve is far arc - near arc <span>÷ 2 = reference angle
</span>
So...algebra wise you'll want to reverse this equation in order to get your missing angle. Like so.
39 <span>x 2 = 78, 135 - x = 78 once again, "x" is your variable / near arc
Therefore your answer for the missing degree is 57</span>°
Answer: 1 over 2
Step-by-step explanation:
Triangle ABC has sides 2,2,2√2
Triangle A'B'C' has sided 1,1,√2
Scale (dilation) factor is less than one because A'B'C' is contracted not dilated. To get A' from A, multiply by 1/2.
Answer:
18
Step-by-step explanation:
if she took nine and her THREE children took three each, that means 3+3+3=9 and 9+9=18
