To solve this equation, simply plug in the value of h = 0 feet, as this would be the height the object will be on the ground. It would be 0.
Afterwards, solve the equation by factoring the quadratic function.
16t^2 - 64t - 80 = 0.
8(2t^2 - 8t - 10) = 0
2t^2 - 10t + 2t - 10 = 0
2t(t - 5) + 2(t - 5) = 0
(2t + 2)(t - 5) = 0
T = 5 and t = -1.
Since time can’t be negative, there is only one solution, t = 5.
It would be about 5 seconds.
Y = -3
-3 + 3 = 0
It is impossible to divide a number by 0

Answer:
Part a) 
Part b) 
The diagram in the attached figure
Step-by-step explanation:
step 1
Find the measure of angle C
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so

substitute the given values




step 2
Find the distance AC
Applying the law of sines

see the attached figure to better understand the problem
substitute the given values


---> rounded to the nearest hundredth
step 3
Find the distance BC
Applying the law of sines

substitute the given values


---> rounded to the nearest hundredth
