The 17 ounce cereal is $0.17 per ounce and the 24 ounce cereal is $0.13 per ounce.
Answer:
As per the statement:
The path that the object takes as it falls to the ground can be modeled by
h =-16t^2 + 80t + 300
where
h is the height of the objects and
t is the time (in seconds)
At t = 0 , h = 300 ft
When the objects hit the ground, h = 0
then;
-16t^2+80t+300=0
For a quadratic equation: ax^2+bx+c=0 ......[1]
the solution for the equation is given by:
On comparing the given equation with [1] we have;
a = -16 ,b = 80 and c = 300
then;
Simplify:
= -2.5 sec and = 7.5 sec
Time can't be in negative;
therefore, the time it took the object to hit the ground is 7.5 sec
747.7
d=14 we are looking for the radius divided it to half so it should be 7
the height is 10
A=2πrh+2πr2=2·π·7·10+2·π·72≈747.69905
21
15 divided by 5/7 is 21
Your vertex would be (3,4)
