Consider the graph of the equation y = 5. Which statements are true? Check all that apply.
levacccp [35]

Answer:

The graph of y=5 is a horizontal line. The point (-4, 5) lies on the lines.

Step-by-step explanation:

This is horizontal because 5 on the y axis is always going to stay the same. For any x value, the y value is 5. Therefore, (-4, 5) is part of that line.

Reptile [31]

Answer:

<em>9%</em>

Step-by-step explanation:

Original rectangle: 100 cm by 200 cm

Original area: 100 cm * 200 cm = 20,000 cm^2

Reduced by 70%, the measures are now 30% of they they were.

30% of 100 cm = 30 cm

30% of 200 cm = 60 cm

New area: 30 cm * 60 cm = 1800 cm^3

New area equals what percent of original area?

1800/20,000 * 100 = 9%

A 28 first slide at a waterpark makes an angle of 60° with the ground as it descends into a pool. What is a vertical distance fr
IceJOKER [234]

Answer:

The vertical distance from the top of the slide go the ground is 24.25 feet

Step-by-step explanation:

Here, we want to calculate the vertical distance from the top of the slide to the ground.

To answer this properly, we shall need the aid of a diagram. Please check the attachment for this;

Mathematically, to calculate this vertical distance, we shall be employing the use of a trigonometric ratio since the shape we are considering is a right-angled triangle

The vertical distance faces the angle given and we can refer to it as the opposite. The length of the slide refers to the hypotenuse

So the trigonometric ratio we are to use will consider the opposite and the hypotenuse

This is the sine

Mathematically sine of an angle = length of the opposite/length of the hypotenuse

let’s call the length of the opposite x

sin 60 = x/28

x = 28 sin 60

x = 24.248 which is 24.25 feet
