Afireworks rocket is shot vertically up in the air. the quadratic function h(t) = −16t^2 + 176t models the height of the rocket above the ground after t seconds. how long does it take for the rocket to return to the ground? asap 3 seconds 7 seconds 11 seconds 15 seconds

Hi there!

The answer would be 11 seconds.

Hope it helps you :)

Hi there! The answer is 11 seconds.

We want to find out when the height of the rocket equals 0 (because then it'll be on the ground). When we know this we can set up an equation.






Therefore the rocket will be returned in the ground after 11 seconds.

The answer is "a"radius = 12.7 unitsdiameter = radius × 212.7 units × 2 = 25.4 units

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
