A goalie punts a soccer ball. If the ball is 1 foot above the ground when her foot meets the ball, find how long it will take, to the nearest hundredth of a second, for the ball to hit the ground. Use the formula h(t)=−16t^2+35t+h0 , where t is the time in seconds and h0 is the initial height. Please help this is really confusing to me

With this question substitute t=3 and t=5 to determine if the two expressions are equivalent. 4(t + 3) 4t+12 which statements are true? check all that apply. a. the value of both expressions when t =5 is 32. b. the two expressions are not equivalent. c. the value of both expressions when t=3 is 15. d. the value of both expressions when t=5 is 23. e. the two expressions are equivalent. f. the value of both expressions when t=3 is 24.
