Answer:
The height of ball is 17 ft at t=0.55 and t=1.14.
Step-by-step explanation:
The general projectile motion is defined as

Where, v is initial velocity and y₀ is initial height.
It is given that the initial height is 7 and the initial upward velocity is 27.
Substitute v=27 and y₀=7 in the above equation to find the model for height of the ball.

The height of ball is 17 ft. Put h(t)=17.


On solving this equation using graphing calculator we get


Therefore the height of ball is 17 ft at t=0.55 and t=1.14.
An equation of the form y = mx + b represents a linear function where m is the slope and b is the y-intercept. For example, y = 3x + 4 represents the linear function whose slope is 3 and whose y-intercept is 4.
Hope this helps!!! The reason why I asked which unit & lesson it is from, is because Idk if you go to k12 or not, by the pic, it looks like you do go to k12... IF you go to K12, I could tell you the answers, that's if I took that lesson... And that's if you'd tell me... Hope I make since.... Ok bye!!! :)
Answer:
B
Step-by-step explanation:
The number is x and you want 6 of that, so that makes 6x
You want 8 less of this, so subtract 8
Therefore you get 6x - 8
Subtract. it from when you do good school
