Answer:

I believe it is -13=-10m+c

Step-by-step explanation:

We use the slope intercept form of y=mx+c. y is the y intercept and x is -10

We plug in y=-13 and x=-10 to get

-13=-10m+c

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 wi
Bezzdna [24]

Answer:

  • Option 4

Step-by-step explanation:

Midpoint of the diameter is the center.

<u>Use midpoint formula to determine the coordinates:</u>

  • x = (2 - 4)/2 = -1
  • y = (5 + 13)/2 = 9

<u>Find the radius using the midpoint and one of the endpoints and the distance formula:</u>

  • r = \sqrt{(-1 - 2)^2 + (9 - 5)^2}  = \sqrt{9+16} = \sqrt{25} = 5

<u>Use the equation of the circle:</u>

  • (x - (-1))² + (y - 9)² = 5²
  • (x + 1)² + (y - 9)² = 25

Correct choice is 4

swat32

Answer:

a) 165.52 degrees.

b)  131.41 degrees.

c)  118.96 degrees.

d)  159.73 degrees.

Step-by-step explanation:

The sine of an obtuse angle is positive as it is in the second quadrant.

a) Using a calculate the angle whose sine ( arcsin) is 0.25  = 14.478 degrees

so the obtuse angle  = 180 - 14.478 = 165.52 degrees to nearest hundredth

b) c) and d) are calculated in the same way.
