If the endpoints of the diameter of a circle are (9, 4) and (5, 2), what is the standard form equation of the circle? a) (x + 7)2 + (y + 3)2 = 5 b) (x − 7)2 + (y − 3)2 = 5 c) (x + 7)2 + (y + 3)2 = 5 d) (x − 7)2 + (y − 3)2 = 5

Just tell me how to set up the equation.

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
