Answer:

D. 4

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(20 - 12) / (4 - 2)

8 / 2

= 4

So, the slope is 4.

Dilation is the process of making something scaled. In the rectangle with a length of 4 and a width of 2, there is no dilation.

<h3>What is the rectangle?</h3>

A rectangle is a quadrilateral whose opposite sides are parallel and are of equal measurement.

<h3>What is dilation?</h3>

Dilation is the process of making something bigger or wider or scaled.

As we have the length of the rectangle as 4 and the width of the rectangle as 2, which is the same as before as well. therefore, there is no change in the length or the breadth of the rectangle. Thus, we can say that there is no dilation in the length and breadth of the rectangle.

Hence, In the rectangle with a length of 4 and a width of 2, there is no dilation.

NemiM [27]

Answer:

The height of the statue is 21.4 feet

Step-by-step explanation:

We are given

A person is standing 50 ft from a statue

The person looks up at an angle of elevation of 16 degree when staring at the top of the statue

hen the person looks down at an angle of depression of 8 degree when staring at the base of the statue

Firstly, we will draw diagram

In triangle ABF:

FC=50

we can use trig formula

tan(16)=\frac{y}{50}

y=50tan(16)

y=14.33727ft

now, we can find x

In triangle DEF:

we can use trig formula

tan(8)=\frac{x}{50}

x=50tan(8)

x=7.0270ft

we can see that

height of statue =x+y

so, the height of statue is

=14.33727+7.0270

=21.4ft
