Both of the statements are Theorems. Postulates are assumed to be true so they are really obvious things like a line has at least two points.

If the point (3/5,4/5) corresponds to an angle θ in the unit circle, what is tan θ ?

serious [3.7K]

A point M on the unit circle could be represented by (x , y), which coordinates are nothing but cos Ф (for x) & sin Ф (for y, hence:

tan Ф = sin Ф / cos Ф ==> tan Ф (4/5) / (3/5) ==> tan Ф =(4/3).

Now let's calculate the angle: tan⁻¹Ф ==> tan⁻¹(4/3) ≈43°

Does anybody know this?Find the area of the regular polygon

sweet [91]

Answer:

<h2>2,268 square units</h2>

Step-by-step explanation:

Step 1

Find the area of 1 Triangle

To find this, we will use this formula:

$A=\frac{1}{2} *B*H$

Let's use the formula!

$A=\frac{1}{2} *14*27\\=\frac{1}{2}* 378\\=189$

<em>The area of 1 triangle is 189 square units</em>

Step 2

Find the area of the whole intire shape by multiplying the area of 1 triangle with the amount of sides.

There are 12 sides, so let's multiply 189 by 12

189x12=2268

<h2>Hence, the area of the regular polygon is 2,268 square units</h2>

Find the constant of variation (k) where y varies directly with x. y = 2, when<br> X = 6.

ExtremeBDS [4]

Answer:

The graph below models the value of a $20,000 car t years after it was purchased.

Value of Car

A graph titled Value of Car has years on the x-axis and Dollars on the y-axis. A line curves down and goes through points (0, 20,000), (4, 10,000), and (14, 2,000).

Which statement best describes why the value of the car is a function of the number of years since it was purchased?

Each car value, y, is associated with exactly one time, t.

Each time, t, is associated with exactly one car value, y.

The rate at which the car decreases in value is not constant.

There is no time, t, at which the value of the car is 0.
