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

Please only answer if you actually know how to). Some methods for graphing equations work well with certain equations and some don't. Help Asap). Knowing which method to select based on the given equation is a valuable skill. You have learned three methods to graph equations. These methods are: • y = mx+ b, • find intercepts, • use a t-chart. A) Using the following 3 equations, answer the questions: 11x + y =4, x+y = -2, x - 2y = 18. 1) How can you determine which equations can be graphed more easily using x - and y -intercepts, rewriting in slope-intercept form, or using a table of values? 2) Which method works best for you personally? When does it not work as well?​

Answer:

please dont blame me if i get this wrong this is what i put.

Step-by-step explanation:

Using the following 3 equations, answer the questions:

11x + y =4, x+y = -2, x - 2y = 18

How can you determine which equations can be graphed more easily using x- and y-intercepts, rewriting in slope-intercept form, or using a table of values?

you can determin which is eiser to graph by wether or not they have numbers infront of the x and y intercepts.  i find it mutch eiser if they allready have the numbers there. its also eiser to graph 11x + y =4 and x - 2y =18 on a slope intercept rather than table of values because you allready can find the points for those two eiser than the last one which would be used on the table of values.  for the problem x+y=-2 you would use x and y intercepts. for 11x+y=4, rewriting in slope form is the corect method to use. and finaly use the table of values method for x-2y=18.

Which method works best for you personally? When does it not work as well?

the one that i find works best for me personally is probably gonna be the slope intercept method as apposed to many other methods. it doesnt work all the time because nothing can but normaly when i have a problem with this method i can just go to the table of values method and get the answer. (sorry if this is wrong this is what im putting for my answer. dont copy and paste this though if u do desiede to use it, read it and turn it into your own words so its not obvious you found the answer on the internet. and tbh i didnt read the lesson i just am ok at comming up with answers useing the question and getting away with it. )

Solve the inequality and write the solution set using both set-builder notation and interval notation. -3a-15≤-2a+6

Answers

Answer:

Set builder notation: {a | a ≥ -21}

Interval notation: [-21, ∞)

Step-by-step explanation:

A set represents a collection of things, objects, or numbers. A set builder notation is in the form y = {x | x is an odd number between 8 and 10}, which means y contains all the odd numbers between 8 and 10.

Interval notation is a way to define a set of numbers between a lower limit and an upper limit using end-point values. for example (8, 20) means numbers between 8 and 20.

Given -3a-15≤-2a+6; solving :

-3a - 15 ≤ -2a + 6

-3a + 2a ≤ 6 + 15

-a ≤ 21

dividing through by -1:

a ≥ -21

The solution is:

Set builder notation: {a | a ≥ -21}

Interval notation: [-21, ∞)

Answer:

105km

Step-by-step explanation:

It is given that; (2.5cm : 15km) is the proportion by which distances are scaled down on a map. One can use this to make a proportion and solve to find how many (km) would represent (17.5cm). (x) will represent the unknown or the number of (km) that one has to solve for.

2.5 : 15 = 17.5 : x

Cross products,

262.5 = 2.5x

Inverse operations,

262.5 = 2.5x\n/2.5\n\n105 = x
