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…

Textbook Question

Chapter 8.4, Problem 63E

Between 1990 and 2013, there was a drop in violent crime and a spike in the prison population m the United States. The bar graph shows the number of violent crimes per 100,000 people and the number of imprisonments per 100,000 people for six selected years from 1990 through 2013.

Chapter 8.4, Problem 63E, Between 1990 and 2013, there was a drop in violent crime and a spike in the prison population m the

a. Based on the information in the graph, it appears that there was a year when the number of violent crimes per 100.000 Americans was the same as the number of imprisonments

per 100,000 Americans. According to the graph, between which two years did this occur?

b. The data can be modeled by quadratic and linear functions

$$$ y = 0.6 x 2 − 28 x + 730

$$$ − 15 x + y = 300

In each function, r represents the number of years after 1990 and y represents the number per 100,000 Americans. Solve a nonlinear system to determine the year described in part (a). Bound to the nearest year. How main violent crimes per 100,000 Americans and how many imprisonments per 100,000 Americans were there in that year?

Students have asked these similar questions

Assume {u1, U2, u3, u4} does not span R³. Select the best statement. A. {u1, U2, u3} spans R³ if u̸4 is a linear combination of other vectors in the set. B. We do not have sufficient information to determine whether {u₁, u2, u3} spans R³. C. {U1, U2, u3} spans R³ if u̸4 is a scalar multiple of another vector in the set. D. {u1, U2, u3} cannot span R³. E. {U1, U2, u3} spans R³ if u̸4 is the zero vector. F. none of the above

Select the best statement. A. If a set of vectors includes the zero vector 0, then the set of vectors can span R^ as long as the other vectors are distinct. n B. If a set of vectors includes the zero vector 0, then the set of vectors spans R precisely when the set with 0 excluded spans Rª. ○ C. If a set of vectors includes the zero vector 0, then the set of vectors can span Rn as long as it contains n vectors. ○ D. If a set of vectors includes the zero vector 0, then there is no reasonable way to determine if the set of vectors spans Rn. E. If a set of vectors includes the zero vector 0, then the set of vectors cannot span Rn. F. none of the above
