Answer:
t = 2.61
Step-by-step explanation:
h (t) = (1/2) x (- 9.8) x t ^ 2 + 12 x t + 2
h (t) = -4.9 x t ^ 2 + 12 x t + 2 (rewritten)
When the ball hits the ground:
-4.9 x t ^ 2 + 12 x t + 2 = 0
Solved:
t1 = -0.16
t2 = 2.61
The negative is irrelevant here. Hence: 2.61.
Answer and Step-by-step explanation:
a - b = 2
= 
b = a - 2
a = b + 2
______________
b = b + 2 - 2
b = b
______________
______________
a = a - 2 + 2
a = a
______________
If a equals 0, then the expression is undefined.
If b = 0, then the expression is 0.
There are infinite number of solutions when a is not 0 and the numbers are positive.

Answer:
Step-by-step explanation:
so you will move constant to the right side and change the sign. 72x=223-7
then you will subtract the numbers 72x=223-7 and that will give you 72=216
then you will divide both sides by 72 and that will give you
- x=3 .
