7.) the equation of the circle is
(x - 3)^2 + (y - 4)^2 = 25
If you substitute the point in you get
(6-3)^2 + (8-4)^2 = 25
3^2 + 4^2 = 25
9 + 16 = 25
25 = 25
Both sides of the equation are the same so it proves it lies on the circle
8.) you add the x coordinates together and divide by 2
7 + 4 = 11
11/2 = 5.5
You use +7 because you need to find the midpoint.
You then add 5.5 to - 7 or - 5.5 from 4
-7 + 5.5 = - 1.5
You do the same for y coordinates
6+5 = 11
11/2 = 5.5
6-5.5 = 0.5
So the coordinates of Rachel's house are
(-1.5, 0.5)
Answer:
4 × 5 = 20
Step-by-step explanation:
Imagine this: the X is 4 and the Y is 5.
You want to find the area of it, so the equation would be
4 × 5 = 20
HOPE THIS WAS HELPFUL!!!!
Answer:
Step-by-step explanation:
By Inscribed Angle Theorem, the value of an inscribed angle enclosed by an arc is the half the value of that arc.
⇒ ∠RPQ = 108°/2
⇒ ∠RPQ = 54°

58. 2 x 7 = 14 for the steps and top, 2 x 3 = 6 for the back, 2 x 4 = 8 for the bottom, ( ( 3 x 2 ) + 3 ) x 2 = 18 for the two sides.
Altogether, the surface area is:
= 14 + 6 + 8 + 18 = 46 units²
