Answer:
2.75 seconds.
Step-by-step explanation:
We have been given that a ball is dropped from the ground. T represents the time in seconds.
To find the time when the ball was in air, we will equate height of ball with 0 and solve for t.
Upon dividing both sides by 4, we will get:
Since our given function is a downward opening parabola, so ball will be in air between both t-intercepts.
Since the ball touches the ground at 2.75 seconds, therefore, the ball would be in air for approximately 2.75 seconds.
D. Because the numbers are reversed
The answer would have to be c. When factoring, the two numbers have to multiply to give you -8 but add to give you -2. The correct factored answer would have been (x-4) (x+2) =0
Answer:
The value of 
.
Step-by-step explanation:
Considering the equation
To solve the equation using inverse operations,
Subtracting 6 on both sides of the equation,
Simplifying,
Dividing both sides by 3
Switching both sides
Therefore, the value of .
