Step-by-step explanation:

The diagram is right angle triangle so we can use SOHCAHTOA

So in the diagram we have 62 degree opposite to x and the hypotenuse

Step 1

Sin62=x/16

Answer:

9.) t=.05m+20

10.) t=.10m+5

11.) 300 minutes of calling would make the two plans equal.

12.) Company B.

Step-by-step explanation:

Let <em>t</em> equal the total cost, and <em>m,</em> minutes.

Set up your models for questions 9 & 10 like this:

<em>total cost = (cost per minute)# of minutes + monthly fee</em>

Substitute your values for #9:

t=.05m+20

Substitute your values for #10:

t=.10m+5

__

To find how many minutes of calling would result in an equal total cost, we have to set the two models we just got equal to each other.

.10m+5=.05m+20

Let's subtract 5 from both sides of the equation:

.10m=.05m-15

Subtract .05m from both sides of the equation:

.05m=15

Divide by the coefficient of m, in this case: .05

m=300

__

Let's substitute 200 minutes into both of our original models from questions 9 & 10 to see which one the person should choose (the cheaper one).

Company A:

t=.05(200)+20

Multiply.

t=10+20

Add.

t=30

Company B:

t=.10(200)+5

Multiply.

t=20+5

Add.

t=25

Answer:

Yes it is a function

Step-by-step explanation:

We have to check the ordered pairs to find out if given relation is a function or not.

In an ordered pair, the first element represents the input and the second element represents the output.

The set of inputs is domain and output is range.

For a relation to be function, there should be no repetition in domain i.e there should be unique pairs of input and output.

In the given relation, the domain is {3,5,-1,-2}.

No element is repeated hence it is a function ..
