The diameter of a circle has endpoints of (2, 5) and (-4, 13). What is the correct equation of this circle? Pls explain and I will mark brainliest!
Answers
Answer:
Option 4Step-by-step explanation:
Midpoint of the diameter is the center.
Use midpoint formula to determine the coordinates:
x = (2 - 4)/2 = -1y = (5 + 13)/2 = 9Find the radius using the midpoint and one of the endpoints and the distance formula:
r = [tex]\sqrt{(-1 - 2)^2 + (9 - 5)^2} = \sqrt{9+16} = \sqrt{25} = 5[/tex]Use the equation of the circle:
(x - (-1))² + (y - 9)² = 5²(x + 1)² + (y - 9)² = 25Correct choice is 4

The total hours spent working :
1 3/4 + 2 1/3 + 1 5/12
7/4 + 7/3 + 17/12
L.C.M = 12
(21 + 28 + 17) / 12
= 66 / 12
= 5 6/12
= 5 1/2
Hourly pay = $10. 50
Total earning :
Total hours * pay per hour
5.5 hours * $10.50
= $57.75

The sum of the heights of two brothers is 10 feet, 4 inches. The difference between their heights is 10 inches. How tall is the shorter brother? (12 inches = 1 foot; Remember to convert into inches first and then into feet at the end.) Let the height of the taller brother = x and the height of the shorter brother = y.
4.75 ft
4.5 ft
4 ft
4.58 ft
Answers
Answer:
4.5 ft
Step-by-step explanation:
Let us assume the height of the taller brother be x
And, the height of the shorter brother be y
Now according to the question
x + y = 10.33
x - y = 0.833
Now solve these two equations
2x = 11.666
x = 5.833
y = 10.33 - 5.83
= 4.5 ft

Draw a diagram of x + 3 and 2x for each situation:
x = 1
x = 2
x = 3
x = 4
Answers
The diagram of x + 3 and 2x are as drawn in the image attached
How to draw a diagram of x + 3 and 2x?Given the situations: x = 1, x = 2, x = 3 and x = 4
For x + 3
x = 1, x+3 = 4
x = 2, x+3 = 5
x = 3, x+3 = 6
x = 4, x+3 = 7
For 2x
x = 1, 2x = 2
x = 2, 2x = 4
x = 3, 2x = 6
x = 4, 2x = 8
You will use the values of x and y = x+3, and the values of x and y = 2x to draw the diagram of the lines as shown in the attached image
