Answer:
1.25 = 1 1/4
Step-by-step explanation:
1/2+1/2 = 0.5+0.5 = 1
1+1/4 = 1+0.25 = 1 1/4 = 1.25
1/2 x 2 = 0.5 x 2 = 1 + 1/4 = 1 + 0.25 = 1.25

Answer: 44
Step-by-step explanation:
f(x)= 6x-4
= 6(8)-4
= 48-4
= 44
Answer:
t = 4 s
Step-by-step explanation
We can infer the origin from the t⁰ term of the quadratic as being 192 feet above the ground. Initial velocity is 16 ft/s from the t¹ term, gravity is -32 ft/s² from the t² term
0 = -16t² + 16t + 192
0 = -t² + t + 12
0 = t² - t - 12
0 = (t - 4)(t + 3)
so either
t - 4 = 0
t = 4 s
or
t + 3 = 0
t = -3 s which we ignore as it occurs before the ball is released.
