Find the unit rate in feet per second 300 yards over 1 minute

arlik [135]

In order to find the unit rate in ft / sec of 300 yards / min. We first have to elicit the conversion values for each unit of measurement, this will allows us identify how much will we multiply in order to get the goaled value.
Conversion values:
1. 1 yard = 3 feet
2. 1 minute = 60 seconds

Solution: 
1. 300 yards x 3 feet/1 yard = 900 feet
2. 1 minute x 60 seconds / 1 minute = 60 seconds

Thus, 900ft/60sec

a leaf hangs from a branch 12 feet in the air. it falls to the ground at a rate of 0.25 feet per second. which graph could repre

Kipish [7]

For this case we have an equation of the form:
$h (t) = (1/2) * (a) * (t ^ 2) + v0 * t + h0
$
Where,
h0: initial height
v0: initial speed
a: acceleration
Substituting values we have:
$h (t) = (1/2) * (- 32) * (t ^ 2) + 0.25 * t + 12
$
Rewriting we have:
$h (t) = -16t ^ 2 + 0.25 * t + 12
$
Note: see attached image
Answer:
$h (t) = -16t ^ 2 + 0.25 * t + 12$
