Understanding Functional Relationships

Mathematics
1 answer:
Elza [17]3 years ago
7 0

Answer:

A horizontal line is an example of a functional relationship.

All functions have an independent variable.

All functions have a dependent variable (At least).

Step-by-step explanation:

By description, a relation is a purpose if each input condition has one and only one output value.

A function has at least a secondary variable and an autonomous variable. For instance, given a function:

Y=X

The secondary variable is "y" and the autonomous variable is "x".

The Field of the role is the collection of potential input values and the Range is the collection of potential output values,

Vertical lines have an irregular slope. Since the value of "x" never varies, an upward line is not an illustration of a functional relationship.

In the matter of Horizontal lines, for any x-value, you get the equivalent y-value. These are described as Constant functions.

Answer:

Sinx = 5/13

cosy = 5/13

cosy = sinx ; they both share a proportional relationship

Step-by-step explanation:

From the attached triangle, since the triangle is right angled, we can use trigonometric functions where ;

sinx° = opposite / hypotenuse

From Pythagoras ;

Hypotenuse = √(opposite² + adjacent²)

Hypotenus = √(12² + 5²)

Hypotenus = 13

Sin x° = opposite / hypotenus = 5 / 13

Sin x° = 5/13

Cos y = adjacent / hypotenus = 5 / 13

Hence,

sinx = cosy

Therefore, they both share a proportional relationship.

Please check my answer: Find the equation of the line that has a slope of -8 and a y-intercept of 2. Answer 4x+y-5
LUCKY_DIMON [66]
Y=mx+b is slope intercept form
m=-8
b=2

y=-8x+2 

your answer is not an equation its an expression so im not sure that would be the answer

The radius of a circle is 4 feet. What is the area of a sector bounded by a 72° arc?
densk [106]
<span>An angle whose vertex is the centre of a circle and whose sides pass through a pair of points on the circle is called a </span>

central angle. The following symbol, pronounced “theta”, is

<span> used to represent a central angle: . </span>

Each central angle forms an arc length between the points

<span> that it passes through on the circle. The arc length of a circle can be found by first calculating what fraction of the circle is represented by the central angle. Then you find the circumference of the circle. Finally, you find the fraction of that circumference. For example, if a circle has a radius of 10.0 cm and a central angle of 60°, to calculate the arc length for that angle we must first determine what fraction of the circle is represented by the central angle 60°. Since there are 360° in a full circle, we can find the fraction of a circle by simplifying ; The sector represents of the circle. To find the arc length, we now need to find the circumference </span>

of the circle. Circumference of a circle is equal to 2 r.

C 5 2 r

5 2 10.0

<span> 62.8 cm The circumference of this circle is about 62.8 cm. To find the arc length, we need to find of 62.8 cm. 62.8 10.5 cm The arc length formed by this central angle is about 10.5 cm. </span><span>
