Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
Find the magnitude of vector <-4,-4>.
Write your answer in simplified radical form.
Express the vector - 6i + 6j + 7k as a product of its length and direction.
- 6i + 6j + 7k =[ODi+Di+ (Dk]
(Simplify your answers. Use integers or fractions for any numbers in the expression.)
The vectoru =
(3140, 2650) gives the numbers of hamburgers and hot dogs, respectively, sold at a fast-food stand in one month. The vector v = (2.25, 1.75) gives the prices (in dollars) of the food items. Find
the dot product u · v.
Interpret the result in the context of the problem.
O The dot product represents the total revenue earned from selling the hamburgers and hot dogs.
O The dot product represents the the total number of hamburgers and hot dogs sold.
O The dot product represents the total revenue earned from selling just the hot dogs.
O The dot product represents the total revenue earned from selling just the hamburgers.
