Answer:

Step-by-step explanation:

The vertex will occur when t=-b/(2a) for the quadratic ax^2+bx+c

In this case

t=-200/(2(-16))

t=-200/-32

t=6.25

g(6.25)=-16(6.25^2)+200(6.25)

g(6.25)=625ft

So the maximum height of the rocket is 625 feet and it reaches this height at 6.25 seconds.

Megan buys a 2-quart bottle of juice for $2.56. What is the unit rate of the cost of the juice?

Mila [183]

Answer: $0.04 per fluid ounce.

Step-by-step explanation:

Let's conver 2 quarts to ounces, as following:

$(2\ quarts)(\frac{32\ ounces}{1\ quarts})=64\ ounces$

You know that she buys a 2-quart bottle of juice (or 64 ounces) for $2.56, therefore, to find the unit rate of the cost of the juice you must divide $2.56 by 64 ounces.

Then, you obtain the following result:

$=\frac{2.56dollars}{64\ ounces}=0.04\frac{dollars}{ounces}$

( $0.04 per fluid ounce)
