Substitute t by its value. the nearness of 3/2 to t denotes multiplication.
y = (3/2 *3) - 5/2
3 is a whole number. it is 3/1 in fraction form.
In multiplying fractions, simply multiply the numerator and the denominator.
y = (3*3 / 2*1) - 5/2
y = 9/2 - 5/2
Subtracting fractions: We can only subtract or add fractions if they all have the same common denominator. Since both fractions have 2 as denominator, we can proceed to subtracting its numerators.
y = (9-5)/2 *subtract numerators and place over the common denominator
y = 4/2 * simplify the fraction.
y = 2/1 or 2

Answer:
Option c is correct
226 feet is the maximum height of the projectile.
Step-by-step explanation:
A quadratic equation , ....[1]
then the axis of symmetry is given by:
As per the statement:
The path of the projectile is modeled using the equation :
....[2]
where, h(t) is the height after t time.
On comparing with [1] we have;
a = -16 and b = 48
then;
sec
Substitute this in [2] we have;
⇒
Simplify:
Therefore, the maximum height of the projectile at 1.5 sec is, 226 feet.
The answer is C on edge
