Answer is : 3x+4 the second one
Answer:
The height of the toy is 9 feet after 1 second
Step-by-step explanation:
we have

where
h(t) is the toys height from the ground
t is the time in seconds
so
For t=1 sec
substitute the value of t in the quadratic equation and solve for h(t)


Answer:
y = 3/4x -2
Step-by-step explanation:
slope = rise/run = 3/4
y intercept is where the line crosses the y axis, it crosses at -2
V = lwh
48 = 8 x 2 x h = 16h
h = 48/16 = 3
height = 3 inches.
that would be the letter d :)
each value of x has a unique value of y
