A table can be used to find the rate of change by giving you a visual representation of how the operation changes over time for example in the link i'm about to post you can see how much more money is earned as more cars are washed, it is showing how much money is being made OVER TIME, hope this helps :)

now to answer your second question, say you would like to know how many miles Tracy ran over a course of 2 hours, the x axis would be the miles and the y axis would be the time, then you would plot the different points on the graph showing the rate at which she is running
'
to answer your last question a linear interval would be a sequence of numbers that when places on a number line they will form a line, a nonlinear interval is a sequence of numbers that don't make a line because there are inequities meaning the numbers in the sequence are all over the place 

Hope this helps and i will post the pictures so you can have a visual representaion

In a table the numbers in the Y column can help you see the change of rate by subtracting the one on top by the one on the bottom. 
example below. You ca see that the number that it gives you it is always the same, therefore that is the change of rate or slope. 

In a graph select 2 points and divide how many numbers to go up and how many in the x axis. then divide them rise÷run=slope

The difference between a linear interval is that the rate of change is always the same. That is why it is a line and not a curve or a circle etc.

Jules kicks a soccer ball off the ground and into the air with an initial velocity of 25 feet
hichkok12 [17]

Answer:

Set up your height equation, then factor or use quadratic formula to find when h(t)=0

Step-by-step explanation:

Your equation will be -16t^2+vt +h where v is the initial velocity and h is the starting height. Now either factor or quadratic equation, whichever is easier for you.

Remember that the ball is on the ground when h(t)=0 since that is the height. There will be two zeros,  one is a negative number so would be before you kicked the ball, the other one will be when the ball comes back down.

If the interest rate on a savings account is 0.018%, approximately how much money do you need to keep in this account for 1 year
Diano4ka-milaya [45]
<span>We are not told how often the interest is compounded, so assuming it is <em /><u><em>compounded yearly</em></u>, you need to keep $9.99 in the account to pay the fee.

<u><em>Explanation: </em></u>
Compound interest follows the formula A=p(1+r)^t,
where:
A is the total amount in the account,
p is the amount of principal,
r is the interest rate as a decimal number,
and t is the number of years.

<u>For our problem: </u>
A = 9.99,
p is unknown,
r = 0.018% = 0.00018,
and t=1.

<u>This gives us: </u>
9.99=p(1+0.00018)^1;
9.99=p(1.00018).

<u>Divide both sides by 1.00018: </u>
9.99=p.</span>
