Best ResponseYou've already chosen the best response.0Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. A rocket is launched from atop a 101foot cliff with an initial velocity of 116 ft/s. a. Substitute the values into the vertical motion formula h = 16t^2 + vt + c. Let h = 0 b. Use the quadratic formula find out how long the rocket will take to hit the ground after it is launched. Round to the nearest tenth of a second. A) 0 = 16t^2+101t+116; 8s B) 0 = 16t^2+116t+101; 0.8s  my answer C) 0 = 16t^2+101t+116; 0.8s D) 0 = 16t^2+116t+101; 8s

Best ResponseYou've already chosen the best response.0\[ x^215=0 \\ x^2= 15 \\ x= \pm \sqrt{15} \] you would not get real number solutions if you had to take the square root of 15 but here, you have two real numbers.

Best ResponseYou've already chosen the best response.0you have the correct equation, but if we used t=1 (which is close to t=0.8) we get 16+116+101 which is not close to zero (we want height = 0 when on the ground)

Best ResponseYou've already chosen the best response.0and one more question Use any method to solve the equation. If necessary, round to the nearest hundredth. 7x^216x=8 0.42, –2.71 my answer 35.43, –33.14 5.42, –2.95 2.71, –0.42

Best ResponseYou've already chosen the best response.0I wasn't sure.. for the second one I was like either B or C are both wrong.. if not B then C, not sure tho @peachpi

Best ResponseYou've already chosen the best response.0the equation you selected is the right one, but 0.8 isn't a solution to it. Check to see that you plugged the numbers into the quadratic equation correctly.
