Hey there!

φ = (pi / 2) * (180 / pi) = 90

So, this would include that sense 90 is on
the on the x-axis, this would mean that this
would be (0).

Your correct answer is \boxed{\boxed{0}}

Hope this helps.

Han's house is 450 meters from school. Lin’s house is 135 meters closer to school. How far is Lin’s house from school?
Marina86 [1]

Solution:

<u>Note that:</u>

  • Han's house = 450 m from school
  • Lin's house = (450 - 135) from school

<u>Looking at the options, we can tell that the letter "z" represents Lin. </u>

  • => z = (450 - 135)
  • => z = 450 - 135

This option matches with Option D.

Option D is correct.

1. If Sheryl works 6.5 hours in a day, she makes approximately 85 currency.

2A. If Sherly had not worked for a single hour, she would get no money.

If she worked for 1 hour, here wage would approximately be equal to 13 currency.

If Sheryl works 9 hours she will make approximately 117 currency.

Step-by-step explanation:

Step 1:

To calculate how much Sheryl makes if she works 6.5 hours a day, we check the graph to see what the y value of the graph is when x =6.5.

When x =6.5, the line falls on y = 85.

So if Sheryl works 6.5 hours in a day, she makes approximately 85 currency.

Step 2:

The two points on the graph are at (0, 0) and (1, 13).

This means that if Sherly had not worked for a single hour, she would get no money.

If she worked for 1 hour, here wage would approximately be equal to 13 currency.

These two statements explain the two points on the graph.

Step 3:

To calculate how much Sheryl makes if she works 9 hours, we must create an equation that represents how much money she makes.

If she earns approximately 13 currency an hour, her wage is y = 13x, where x is the number of hours worked and y is the wage.

When x =9, y = 9(13) = 117.

So if Sheryl works 9 hours she will make approximately 117 currency.

Monica [59]

<u>Answer</u>:

Given below.

<u>Step-by-step explanation</u>:

1) Hypotenuse

2) Using Pythagoras theorem:

              35² + 12² = c²

                c = √1225+144

                c = √1369

                 c = 37  ....this is the length of missing side.

Here given that opposite is 35 , adjacent is 12 , hypotenuse is 37.

3) sin(θ) = opposite/hypotenuse

   sin(θ) = 35/37

4) cos(θ) = adjacent/ hypotenuse

    cos(θ) = 12/37

5) tan(θ) = opposite/adjacent

      tan(θ) = 35/12
