A rational number is that number that can be expressed as a ratio between two integers. Thus integers are also rational numbers: ex: 7=7/1=14/2, 5=-5/(-1)=5/1=15/3,....

Examples of rational numbers: 1/5, 2/3, -5/7, etc

The diameter of your bicycle wheel is 20 inches. How far will you move in one turn of your wheel?

To do this,  You must know the formula.  D=3.14l*r  Or,  Distance=3.14length*revolutions
3.14 is pi.
Revolutions are the turns of a wheel.
Plug in your numbers.  D=3.14*20*1

Answer:

Step-by-step explanation:

Any time you have compounding more than once a year (which is annually), unless we are talking about compounding continuously, you will use the formula

A(t)=P(1+\frac{r}{n})^{(n)(t)}

Here's what we have:

The amount after a certain time that she has in the bank is 4672.12; that's A(t).

The interest rate in decimal form is .18; that's r.

The number of times the interest compounds is 12; that's n

and the time that the money is invested is 3.5 years; that's t.

Filling all that into the formula:

4672.12=P(1+\frac{.18}{12})^{(12)(3.5)} Simplifying it down a bit:

4672.12=P(1.015)^{42} Raise 1.015 to the 42nd power to get

4672.12 = P(1.868847115) and divide to get P alone:

P = 2500.00

She invested $2500.00 initially.

<u>Answer</u>

y = (1/2)x - 1


<u>Explanation</u>

The first step is to get the gradient of the line.

The two points in the line are; (2,0) and (-2, -2).

Gradient = (-2 - 0)/(-2, - 2)

                = -2/-4

                 = 1/2

To get the function we use one of the point (2,0) and a general point (x,y).

1/2 = (y - 0)/(x - 2)

1/2 = y/(x - 2)

(x - 2) = 2y

2y = x - 2

y = (1/2)x - 1
