Answer:
<em>(D). (8, - 5) </em>
Step-by-step explanation:
Coordinates of a center of a circle (x - h)² + (y - k)² = r² is (h, k)
Coordinates of the midpoint are ( , )
(x² - 10x + 25) + (y² + 2y + 1) = 25
(x - 5)² + (y + 1)² = 5²
(5, - 1) are coordinates of the center of the circle and (5, - 1) is a midpoint of the segment connected (2, 3) and (x, y)
5 = (2 + x) / 2 ⇒ x = 8
- 1 = (3 + y) / 2 ⇒ y = - 5
<em>(D). (8, - 5)</em>
Answer:
x = 24
Step-by-step explanation:
ED is the angle bisector of ∠GEH , thus the following ratios are equal
= , that is
= ( cross- multiply )
56(x + 4) = 1568 ( divide both sides by 56 )
x + 4 = 28 ( subtract 4 from both sides )
x = 24
First, look at the ratio. And out of 2&3&4, 2 is the smallest. So, change the 2 to 15, 3 to X, 4 to Y. Like this down below
15:X:Y
Now, if 2=15, 1=15÷2, which is 7.5
If one is 7.5, the X=3×7.5=22.5
Y=4×7.5=23
Add them all up, 15+22.5+23=60.5
The perimeter is 60.5
Answer:$3.25
Explanation:
Since the 7 min phone call is at 1.75, that means that one minute of phone call time is 0.25. 13 minutes would be 0.25*13=3.25
hope this helps
