Explanation Given: There is a bar graph that shows the disposable income in the various years and the expression is | x − 31 , 500 | ≤ 4400 . Calculation: Calculate the number of years where the expression | x − 31 , 500 | ≤ 4400 is true. The value of x is the disposable income of the respective years. In year 2005: Year 2005 = | x − 31 , 500 | ≤ 4400 = | 31 , 300 − 31 , 500 | ≤ 4400 = | − 200 | ≤ 4400 = 200 ≤ 4400 In year 2005, the expression is true. In year 2006: Year 2006 = | x − 31 , 500 | ≤ 4400 = | 33 , 200 − 31 , 500 | ≤ 4400 = | 1 , 700 | ≤ 4400 = 1 , 700 ≤ 4400 In year 2006, the expression is true. In year 2007: Year 2007 = | x − 31 , 500 | ≤ 4400 = | 34 , 600 − 31 , 500 | ≤ 4400 = | 3100 | ≤ 4400 = 3100 ≤ 4400 In year 2007, the expression is true

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…

Suppose an oil spill covers a circular area and the radius, r, increases according to the graph shown below where t represents the number of minutes since the spill was first observed. Radius (feet) 80 70 60 50 40 30 20 10 0 r 0 10 20 30 40 50 60 70 80 90 Time (minutes) (a) How large is the circular area of the spill 30 minutes after it was first observed? Give your answer in terms of π. square feet (b) If the cost to clean the oil spill is proportional to the square of the diameter of the spill, express the cost, C, as a function of the radius of the spill, r. Use a lower case k as the proportionality constant. C(r) = (c) Which of the following expressions could be used to represent the amount of time it took for the radius of the spill to increase from 20 feet to 60 feet? r(60) - r(20) Or¹(80-30) r(80) - r(30) r-1(80) - r−1(30) r-1(60) - r¹(20)
