Answer:
h(t) = -16t^2 + 40t + 120
h(t) = -16(t^2 - 5/2*t) + 120
h(t) = -16(t^2 - 5/2*t + (5/4)^2 - (5/4)^2) + 120
h(t) = -16(t^2 - 5/2*t + (5/4)^2 - 25/16) + 120
h(t) = -16(t^2 - 5/2*t + (5/4)^2) + 120 + 25
h(t) = -16(t - 5/4)^2 + 145
The rock needs 5/4 = 1.25 seconds to travel to the highest point wich is 145 m high.
The answer to this question is 82
Answer:
7 bucks
Step-by-step explanation:
x*.8=5.62
divide both sides by .8
x=7
The vertical shifts in graphs are caused by a constant added to the output (y - axis).
<h3>What is vertical shift in a graph?</h3>
Vertical shifts are outside changes that affect the output (y- axis) values and shift the function up or down (vertical direction).
Horizontal shifts are inside changes that affect the input (x-) axis values and shift the function left or right
<h3>The cause of vertical shift in a graph</h3>
The vertical shift results from a constant added to the output (y - axis). The graph will move up if the constant added is positive OR it will move down if the constant is negative.
Thus, the vertical shifts in graphs are caused by a constant added to the output (y - axis).

P² - 12 p - 13 = 0
Δ = ( -12)² - 4 ( 1 * - 13)
Δ = 144 + 52
Δ = 196 = 14²
x₁ = (- ( -12) + 14 ) / 2 = 26/2 = 13
x₂ = ( - ( -12) - 14) /2 = - 2 /2 = - 1
S = 13
