Answers

A set of ordered pairs in which each input has exactly one output is called a function. Then the correct option is D.

What is a function?

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

A finitary relation over sets X1,..., Xn is a subset of the Cartesian product X₁, ....., Xₙ in mathematics; specifically, it is a set of n-tuples made up of the components xi in Xi. Typically, the relation describes a potential link between n-components. tuple's

A set of ordered pairs in which each input has exactly one output is called a function. Then the correct option is D.

The bull’s-eye on a target has diameter 2 in. What is the area of the bull’s-eye to the nearest tenth? Use 3.14 for π.

Answers

Answer:

20.3cm^2

Step-by-step explanation:

Bullseye has a circular shape. So area of a bulleyse = Pi x (radius) ^2

Díameter is 2 inches = 5. 08cm

But radius = diameter /2

Radius = 5.08cm /2

Radius = 2.54cm

Hence Area of bulleyse = 3.14 x (2.54) ^2

= 3.14 x 6. 451 cm^2

= 20.256 cm^2

=20.3cm^2 (to nearest tenth)

What scale factor was used when going from the grey triangle to the yellow triangle

Answers

Answer:

It was used    (1)/(3)   as scale factor.  

Step-by-step explanation:

The scale factor is the ratio of two corresponding side lengths of similar figures. Similar figures have the same shape but are of different sizes.

To find the scale factor that was used when going from the grey triangle to the yellow triangle we can work with any of the three sides of the grey triangle.

Let's work with the below side.

The below side is extended from the point (-2,4) to the point (7,4)

The length of this side is 9 units.

In the yellow triangle, we can see that the below side is extended from the point (2,0) to the point (5,0)

The length of this side is 3 units.

Working with the lengths and the scale factor ⇒

(9units).(ScaleFactor)=3units

ScaleFactor=(3units)/(9units)=(1)/(3)

We find that the scale factor that was used when going from the grey triangle to the yellow triangle is (1)/(3)

Answer:

Scale factor of 1/3
