4. It cannot be a constant or unit rate relationship because the value of k = y/x vary across table values.

5. The relationship in Tuesday's table can be described by a constant unit rate.

<h3>What is a Constant Unit rate Relationship?</h3>

A constant unit rate relationship can be described as a relationship between two input and output variables, x and y, in such a way that, k = y/x. "k" is the constant of proportionality of the relationship or the unit rate between the two variables.

4. We have the following:

5/20 = 1/4

10/40 = 1/4

12/60 = 1/5

14/80 = 7/40

16/100 = 4/25

Thus, this cannot be a constant or unit rate relationship because the value of k = y/x vary across table values.

5. 4/20 = 1/5

8/40 = 1/5

12/60 = 1/5

16/80 = 1/5

20/100 = 1/5

Thus, the value of k is the same across all table values, therefore, the relationship in Tuesday's table can be described by a constant unit rate.

Three trigonometric functions for a given angle are shown below. Sine theta = Negative StartFraction 77 Over 85 EndFraction, cos

Likurg_2 [28]

Trigonometric functions are the ratio of the different sides of a right-angled triangle. We can say that the coordinates of the point are (-77, 36).

<h3>What are trigonometric functions?</h3>

Trigonometric functions are the ratio of the different sides of a right-angled triangle.

$\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}$

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

Given to us

$Sin(\theta) = \dfrac{-77}{85}$

$Cos(\theta) = \dfrac{36}{85}$

$Tan(\theta) = \dfrac{-77}{36}$

As we know that the Tangent(Tan) is the ratio of perpendicular and base. therefore, we can write the function as,

$\rm Tan(\theta) = \dfrac{Perpendicular}{Base} = \dfrac{-77}{36}$

therefore, the length of the perpendicular is 77, while the length of the base is 36.

As given to us that the value of sin is negative, therefore, the perpendicular will be on the negative side of the y-axis. While the value of cos is positive, therefore, the base will be on the positive side of the x-axis.

Thus, we can say that the coordinates of the point are (-77, 36).
