Y=Mx+b m is the slope and b is the y intersect so where x hits 0
Answer: z
Step-by-step explanation:
The height of the balloon is given as h(t) = -16t² + 40t + 12 at 2 seconds, the height is 28 feet
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height of the water balloon after t minutes, hence:
h(t) = -16t² + vt + h₀
Where h₀ is the initial height = 12 feet and v is the initial velocity, hence:
h(t) = -16t² + vt + 12
The height of 37 feet after 1.25 seconds, hence:
37 = -16(1.25)² + v(1.25) + 12
v = 40 m/s
h(t) = -16t² + 40t + 12
After 2 seconds:
h(t) = -16(2)² + 40(2) + 12
h(2) = 28 feet
The height of the balloon at 2 seconds is 28 feet

Use the geometric series formula:
S_n = [a_1(1 - r^(n)]/(1 - r)
Let a_1 = 3
Let n = 8
Let r = 1/2
S_8 = [3(1 - (1/2)^8]/[(1 - (1/2)]
Simplify the right side using your calculator to find S_8, which is the sum of the first 8 terms.
