Answer:
5secs
Step-by-step explanation:
Given the equation of the height expressed ad;
h(t) = - 16t^2 + initial height
Given that initial height = 400feet
h(t) = - 16t^2 + 400
The waste will hit the ground at when h(t) = 0
substitute
0 = - 16t^2 + 400
16t^2 = 400
t² = 400/16
t² = 25
t = √25
t = 5secs
Hence it will take the easte 5secs to hit the ground
y=1
thats the answer
Rate is a ratio of different units ( a quantity times a quantity), such as miles per hour.
Unit rate is a rate with a denominator of 1.
To find unit rate, divide the total cost by the quantity:
0.89 / 16 = 0.0556 per ounce.
