Suppose a projectile is launched from a tower into the air with an initial velocity of 48 feet per second. Its height, H, in feet, above the ground is modeled by the function `H=-16T^{2}+VoT+64`

where T is the time, in second, since the projectile was launched and `Vo` is the initial velocity.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

do you have an easier question cause this shh is hard like theheck

step-by-step explanation:

you first to choose the points and then move from then as the slope you have
