Answer:

b. The domain is all real numbers less than or equal to 81; and The range is not all real numbers because the square root symbol applied to a non-negative number is non-negative.

Step-by-step explanation:

The square root function is not defined in the real number system for the square root of a negative number.

In order for the number under the radical sign to be positive, then the value of x must be all numbers less than or equal to 81.

The range cannot be negative numbers, since the square root of a positive number will give a positive answer.

This makes the correct choice b.

The slide is 4 meters due west of the tire swing and 3 meters due south of the monkey bars. What is the distance between the tir

padilas [110]

Answer:

The distance between the tire swing and the monkey bars = 5 m

Step-by-step explanation:

Given:

Distance between tire swing and the slide = 4 m

Distance between monkey bars and slide = 3 m

We have to find the distance between tire swing and the monkey bars.

Let the distance be "h" meters.

From the diagram we can see that when they are arranged they form a right angled triangle.

Where the distance we have to find is the hypotenuse of the triangle.

Using Pythagoras formula:

⇒ (hypotenuse)^2 = (base)^2 + (perpendicular)^2

Plugging the values:

⇒ $(hypotenuse)^2 = (base)^2 + (perpendicular)^2$

⇒ $h^2=b^2+p^2$

⇒ $h=\sqrt{b^2+p^2}$

⇒ $h=\sqrt{(4)^2+(3)^2}$

⇒ $h=\sqrt{16+9}$

⇒ $h=\sqrt{25}$

⇒ $h=5$ m

So,

The distance between the tire swing and the monkey bars = 5 m
