Which equation would best solve the following problem?
maria releases a javelin 1.5 meters above the ground with an initial vertical velocity of 22 meters per second. how long will it take the javelin to hit the ground?
–4.9t^2 + 22t + 1.5 = 0
–4.9t^2 + 22t = 1.5
–4.9t^2 + 1.5t + 22 = 0
–16t^2+ 22t + 1.5 = 0

H(t) = ho +Vo.t - (g*t^2)/2

h(t) = 1.5 + 22t -4.9t^2

h(t) = 0 ⇒ -4.9t^2 + 22t + 1.5 =0. This is the first option.

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
