Answer:
t1= 1.1475 sec
t2=9.48 sec
Step-by-step explanation:
This question asking for the time when an object reach a specific height. I will explain what the formula stand for to make this easier.
h= height = 174feet
v0= initial velocity = 170 feet/s
t= time
h0= initial height= ground level = 0
The question have predetermined formula for the height, so we should use it instead of formula that involve gravity value.
h= -16 +v0t + h0t
174 feet = -16 + 170 feet/s x t + 0 x t
-16 + 170 feet/s x t - 174 feet = 0
8 - 85 feet/s x t + 87 feet = 0
This equation will be hard to solve since its value in fraction, so lets use the quadratic formula
t1=
t1= 1.1475
t2=
t2=9.48
Answer:
the sum of two whole numbers is always greater than either number because even if one of the numbers to be added is 0, the answer will, well, not be greater, but at least equal to it.

Answer:
x= -8 or -2
Step-by-step explanation:
(im assuming that x2 is x²)
x²+10x+16=0
(x+2)(x+8)=0
x=-8 or -2
