Four points on an ellipse are (9, -2), (-5, -9), (1, 0), and (11, -5). Use matrices to represent the system of equations using the general form and all four points, in the order given. The first point corresponds with the first row, etc. (Note: The A value is 1, so set the equations up to solve for C, D, E, and F.)

The matrix representation of the equations for the coefficients is attached.

i have no idea just need points sorry

step-by-step explanation:

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
