Intersection points:
By adding the value of the first year (1970) into the x-value that is
Important: It's h = -16t^2 + 30t + 4, where " ^ " indicates exponentiation.
The units of measurement of h(t) are "feet."
Note that if time t = 0, h(0) = 4. This is the "initial value" of your function, the height off the ground of the ball at the very beginning.
As time progresses, the ball will travel skyward, slow down, momentarily stop moving, and then fall to the ground at an increasingly faster rate.
Here's the table of t and h values that you wanted:
t (sec) h(t) (feet)
0
4
0.5
15
1
18
1.5 4
2.0 0
Note that the ball must stop moving when it hits the ground. According to this table, that happens at time 2 sec. The max height reached by the ball is in the neighborhood of 18 ft, after 1 sec of upward travel.
To answer this item, I assume that it is compounded yearly such that the amount of interest (I) from the given present worth (P), interest rate (i) and the number of years (n) is calculated through the equation,
I = P x (1 + i)^n - P
Substituting,
I = ($55) x (1 + 0.04)^5 - $55
I = 11.91
The answer is nearest to the first choice, $11.
The answer is 231 square feet. 45% is .45 in decimal form. You would multiply .45 by 420 and get 189. Then you would subtract 189 from 420 and get 231.
