What is the equation of a circle that has a center at point T (-3,-1) and passes through the point (1,-6)
First we need to find out the radius of the circle, radius = sqrt[(-5)^2+4^2] = sqrt(41) The equation of a circle that has a center at point T (-3,-1) and passes through the point (1,-6) is (x + 3)^2 + (y + 1)^2 = 41

Questions asked by the same visitor
If the diagonal of a rhombus are 6 and 8, what is the area of the rhombus?
Weegy: The area is 24. The rhombus is seperated in 4 triangles by the diagonals and each triangle has area equal to: (8/2)*(6/2)/2= 6. The area of eah triangle multiplied by 4 gives the total area: 6*4=24. User: A wooden fence 4 feet high and 200 feet long is to be painted.

A wooden fence 4 feet high and 200 feet long is to be painted. The amount of gallons of paint needed if one gallon covers 300 square feet is: (4*200)/300 = 800/300 = 8/3 = 2.7 gallons.

Two angles are complementary. The measure of the smaller angle is five less than the measure of the larger angle. What is the measure of the smaller angle?
Weegy: The answer is 30, 60. User: DO,K = (6, 12) (3, 6) (More)
Updated 4/3/2014 8:52:55 AM
Let x be the measure of the smaller angle, the measure for the bigger one is x + 5.
The angles are complementary, so x + x + 5 = 90
solve the equation we get x = 42.5 degrees.
The smaller angle is 42.5 degrees.
