Find the equation of the line.
hoa [83]

Answer:

y=3x+3

Step-by-step explanation:

To find the slope, find two points and use the rise over run.

Some points you can use are (0, 3) and (1, 6)

The rise is 3 and the run is 1.

3/1 = 1.

The slope is 3.

To find the y-intercept, find the point where x = 0.

(0, 3)

The y-intercept is 3.

Now you can write an equation.

y=mx+b

m is the slope and b is the y-intercept.

y=3x+3

Write the standard form of 1x1/10 + 8x1/100
alisha [4.7K]
We are given the expanded form and we need to write the standard form:
10 + 8x(1/10) + 3 x(1/100) + 9 x (1/1000)
So, that is:
10 + 0.8 + 0.03 + 0.009
= 10.839

22. Use your model to determine when the volume of oil will get down to 500 gallons.
Helen [10]

Answer:

  21.  y = 75000·0.935^t

  22.  after 74.6 days

  23.  y = 27.8112·1.18832^t

  24.  18.8% per month

  25.  1748

Step-by-step explanation:

22. It is convenient to use the graphing calculator to solve this problem. The number of days is where the exponential curve has the value 500. It is about 74.55 days. (see the first attachment)

__

23. y = 27.8112·1.18832^t (see the second attachment)

__

24. The rate of change is the difference between the base of the exponential and 1, often expressed as a percentage. The time period is the units of t.

  (1.18832 -1) × 100% ≈ 18.8% . . . . per month

__

25. Evaluating the function for t=24 gives y ≈ 1748.30425259 ≈ 1748.

_____

<em>Comment on graphing calculator</em>

A graphing calculator can make very short work of problems like these. It is worthwhile to get to know how to use one well.
