consider the parabola with a focus at the point (4,0) and directrix y = 3.
which two equations can be used to correctly relate the distances from the
focus and the directrix to any point (x, y) on the parabola?
o a. a = 3 - y, a = (x+4)2 + (y +0)2
o b. a = 3-y; a= vox= 492 +(+0)2
o c. a=y-3; a = v(x– 4)2 + (y +0)2
o d. a=y-3; a = vx+4)2 + (y +0)2

Select the correct answer from each drop-down menu. rewrite the formula to find voltage. the formula for electrical power (p, in watts) is where v is the voltage in volts and r is the resistance in ohms. for a particular brand of water heater, r is 32 ohms and p is 0.5 watts. the formula to find v is , and the voltage at which the heater operates is volts.

Is trapezoid abdc the result of a dilation of trapezoid mnpq by a scale factor of ? why or why not? yes, because ab and cd are each the lengths mn and qp. yes, because sides ab and cd are parallel to sides mn and qp. no, because ab is the length mn but cd is the length qp. no, because sides ab and cd have different slopes from sides mn and qp.
