Find the sum of the given vectors and illustrate geometrically. [-1,4],[6,-2]
cricket20 [7]

Answer:

The sum of vectors is <5,2>.

Step-by-step explanation:

The given vectors are <-1,4> and <6,-2>.

We need to find the sum of the given vectors and illustrate geometrically.

Plot the point (-1,4) on a coordinate plane and draw a vector <a> from (0,0) to (-1,4).

Plot the point (6,-2) on a coordinate plane and draw a vector <b> from (0,0) to (6,-2).

Now complete the parallelogram and the diagonal represents the sum of both vectors.

The end point of the diagonal is (5,2). It means sum of vectors is <5,2>.

Check the sum of vectors:

+==

Therefore, the sum of vectors is <5,2>.

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $13 monthly fee
Tpy6a [65]

Answer:

With 250 minutes of calls the cost of the two plans is the same

Step-by-step explanation:

We must write an equation to represent the cost of each call plan.

<u>For the first plan</u>

Monthly fee

 $ 13

Cost per minute

 $ 0.17

If we call x the number of call minutes then the equation representing the cost c for this plan is:

c = 13 + 0.17x

<u>For the second plan</u>

monthly fee

$ 23

Cost per minute

$ 0.13

If we call x the number of call minutes then the equation representing the cost c for this plan is:

c = 23 + 0.13x

To know when the cost of both plans are equal, we equate the two equations and solve for x.

13 + 0.17x = 23 + 0.13x\\\\0.17x -0.13x = 23-13\\\\0.04x = 10

x = \frac{10}{0.04}

x = 250\ minutes

With 250 minutes of calls the cost of the two plans is the same: $55.5
