A rocket is launched upward so that its distance, in feet, above the ground after t seconds is represented by the function below. What is its maximum height? h(t)=−16t2+320t

Answers

Answer: 1600 feet.

Step-by-step explanation:

Given : A rocket is launched upward so that its distance, in feet, above the ground after t seconds is represented by the function $h(t)=-16t^2+320t$

To find : its maximum height.

First we differentiate the given function , we get

$h'(t)=(2)(-16)t+320=-32t+320$

Put $h'(t)=0$ , we get

$-32t+320=0\n\n\Rightarrow\ t=(-320)/(-32)=10$

Hence, at t=10 , rocket achieves its maximum height.

$\text{Maximum Height =}h(t)=-16\left(10\right)^(2)+320\left(10\right)\n\n=-1600+3200=1600$

Hence, its maximum height = 1600 feet.

Answer:

1600 ft

Step-by-step explanation:

We are given that a rocket is a launched upward so that its distance(feet) above the ground after t seconds is represented by the function

$h(t)=-16t^2+320t$

We have to find the maximum height.

Substitute h(t)=0

$-16t(t-20)=0$

$t=0,t-20=0\implies t=20$

When t=0 it means the rocket is at ground launch.

When t= 20 s.

Total time taken by rocket=20 s.

Half of the time taken to reach maximum height and half of the time taken to reach ground back.

Therefore, time taken by rocket to reach maximum height= $(20)/(2)=10s$

Substitute t=10 in given function

Then we get

h(10)=-16(10)^2+320(10)=-1600+3200=1600 ft[/tex]

Hence, the maximum height=1600 ft

A restaurant mixes homemade barbecue sauce with their smoked pulled pork using a ratio of two cups of sauce for every four pounds of shredded pulled pork. Write two rates to represent this relationship.

Answers

The two rates that can be used to represent this relationship are:

2 cups : 4 pounds, and
1 cup : 2 pounds

What is a ratio?

A ratio is a comparison between two numbers that can be separated with (:) sign or can be represented as a fraction. This comparison deals with the same units.

However,

A rate of a ratio deals with the comparison between different units.

From the parameters given:

The ratio rates occur between the homemade barbecue and smoked pulled pork

For every 2 cups of barbecue sauce, 4 pounds of pulled pork is used.

Therefore, we can conclude that the two rates that can be used to represent this relationship are:

2 cups : 4 pounds, and
1 cup : 2 pounds

Solving EquationsIf an elephant travels for 4 hours at
6.5 mph and a giraffe travels for 2
hours at ll mph, who covers more
distance?
E. elephant
F. giraffe
G. They travel the same distance.
H. cannot be determined based on the
information provided
Q2

Answers

The elephant; 6.5 mph for 4 hours equates to 26 miles, while the Giraffe only covers 22 miles (2*11)

Final answer:

The elephant covers more distance than the giraffe.

Explanation:

To determine who covers more distance, we need to calculate the distance traveled by each animal. The distance traveled can be calculated using the formula: distance = speed × time. For the elephant, the distance is 6.5 mph × 4 hours = 26 miles. For the giraffe, the distance is 11 mph × 2 hours = 22 miles. Since the elephant covers a greater distance, the answer is E. elephant.
