You can replace x with any number and get an answer except -1, because the denominator becomes 0, and division by 0 is undefined.

So the domain is:  {-∞ < x < -1}  ∪ {-1 < x < ∞}

To find  A(2), replace t with 2 to get:  3 - 2(2)² +4^2  =  11

To find  A(1), replace t with 1 to get:  3 - 2(1)² +4^1  =  5

To find  A(2) - A(1), subtract the two values. 

Because "pi" is the name of the Greek lower case letter, π.

In 1706, William Jones was the first person to use this letter to name the value:  3.1415926535...

This was included in the works of others, and it caught on.

The meansurement that is 82 ft is rounded to the nearest foot, it is somewhere between 81.5 and 82.5 feet.

The measurement that is 18.2 ft is rounded to the nearest one-tenth of a foot, it is somewhere between 18.15 and 18.25 ft.

The second measurement is more precise.

If a linear equation is solved for y, it has the form:  y  =  mx + b

m is the coefficient of the x-term and is the slope.

b is the number added to the end, it is the y-intercept.

6b + 8  =  3b - 2

Subtract 3b from both sides:

3b + 8  =  -2

Subtract 8 from both sides:

3b  =  -10

Divide both sides by 3:

b  =  -10/3

Since it costs $5.00 to enter and another $0.50 per ticket, a formula could be:

     y  =  5 + .5x          where x is the number of tickets purchases and y is the total amount of money.

This doesn't fit with the next line that says that the cost for 5 rides is $25.50 and the cost for 10 rides is $55.00.

If you want to graph the 5 rides for $25.50 and 10 rides from $55.00,

         create the two points (5, 25.5) and (10, 55) and graph these two points.

The compound interest formula is:  A  = P(1 + r/n)^(n·t)

where:     A  =  final amount              P  =  beginning amount         r  =  rate (as a decimal)

                n  =  number of times compounded per year                  t  =  number of years

Find 45% of 1501

  .45 x 1501  =  675.45

A slope of  -5  is a slope of  -5/1;  which means, that every time you move one space to the right, you move 5 spaces down.

Place a dot at  (0, 10), ove to the right 1 space and down 5 spaces; keep doint this until you hit the x-axis.

This is the place that he will hit the water.
