What is the standard form of the equation of the circle x 2 + 14x + y 2 - 6y - 23 = Solve the system by the method of substitution. ![]() Solve the system by the method of elimination and check any solutions Use the Binomial Theorem to expand and simplify the expression. The ship received the signal from Q 3 μs (microseconds) before the Moment, both towers sent a radio signal to a ship out at sea, each traveling atģ00 m/μs. Shore where the x-axis runs through (all distances are in meters). Two control towers are located at points Q(-500, 0) and R(500, 0), on a straight Rotate the axes to eliminate the xy-term in the equation. Give the coordinates (enclose the coordinates in parentheses) of the foci, vertices, and covertices ofįind the sum using the formulas for the sums of powers of integers. The correct answer is: (x + 4) 2 = -12(y - 2) The correct answer is: a single point at the center.įind the equation in standard form of the ellipse whose foci are F 1 (-8,0) andį 2 (8,0), such that for any point on it, the sum of its distances from the foci is 20. two points, one inside and one outside the circle.ĭ. In order to graph a circle one must graph all the points that are equidistantĪ. The correct answer is: (x + 5) 2 + (y - 2) 2 = 6 2įind the standard equation of the hyperbola which satisfies the given condition:Īsymptotes y= 43 x+ 13 and y=− 43 x+ 413 ,a vertex (−1,7)y=43x What is the standard form of the equation of the circle x 2 + y 2 + 10x - 4y - 7 = 0? TheĬoordinates of a point in the xy-coordinate system are given. The x’y’-coordinate system has been rotated θ degrees from the xy-coordinate system. The correct answer is: (y - 3) 2 = 10(x + 8) The correct answers are: (-3, 0), (0, -3), (3, 0), (-3, 0)įind the standard equation of the parabola which satisfies the given condition: The coordinates of the point in the rotated coordinate system. The coordinates of a point in the xy-coordinate system are given.
