Answer:
4/2=2
Step-by-step explanation:
When determining the slope of a line from a graph, slope is rise over run. Your line rises 4 points and then runs 2 points from point a to point b.
Here the time function is h(t) = [6 + 96t - 16t^2] feet.
The initial height of the ball is 6 feet. That's when t=0. h(0)=[6+0-0] ft = 6 ft.
At t=7 sec, h(t) = [6 + 96t - 16t^2] feet becomes
h(7 sec) = h(t) = [6 + 96(7) - 16(7)^2] feet This produces a large negative number (-106 ft), which in theory indicates that the ball has fallen to earth and burrowed 106 feet into the soil. Doesn't make sense.
Instead, let t=1 sec. Then h(1 sec) = h(t) = [6 + 96(1) - 16(1)^2] feet
=[6 + 96 -16] ft, or 86 ft.
One sec after the ball is thrown upward, it reaches a height of 86 feet. It continues to rise, slowing down, until it finally stops for an instant and then begins to fall towards earth.
Answer:
2 1/2
Step-by-step explanation:
1st, convert the fractions
2 2/3 = 2 4/6 = 16/6
5 1/6 = 31/6
31/6-16/6 = 15/6 = 2 3/6 = 2 1/2
