Mathematics
1 answer:
boyakko [2]1 year ago
4 0

Using it's concept, it is found that the domain and range of the function are given by:

D: [–4, ∞) and R: [0, ∞)

<h3>What are the domain and the range of a function?</h3>
  • The domain of a function is the set that contains all the values of the input.
  • The range of a function is the set that contains all the values of the output.

In this problem, the function is:

g(x) = \sqrt{x + 4}

The square root function does not exist for negative values, hence the domain is represented by:

x + 4 \geq 0 \rightarrow x \geq -4

The range of the square root function is x \geq 0, which remains the same as there are no vertical translations.

Hence the correct option is given by:

D: [–4, ∞) and R: [0, ∞)

The perimeter of the rectangular base of a monument is 210.5 feet. If the width is equal to its​ length, what are the dimensions
Ann [662]
If width is equal to length then it's a square.
perimeter in this case would be 4x length of each side.
that is( 4 x length)= 210.5
length= width= 210.5/4= 52.62 feet

Which of the following is true about the expression below?
agasfer [191]
Answer:

The first one

Explanation:

9 and 1/4 are both rational numbers (which are numbers that can be represented in a fraction; 9 can be represented as 9/1)
And since it equals to 9/4 (or 2 1/4) the product is also a rational number.

A right cone has radius 9cm and slant height 12cm. The radius and slant height are both multiplied by 2/3. Which of the followin
Olegator [25]

Answer:

<em>The surface area is multiplied by 4/9.</em>

Step-by-step explanation:

<u>Surface Area of a Cone</u>

Being r the radius and l the slant height of a cone, then its surface area is

SA=\pi r^2+\pi r l

Now let's think both the radius and the slant height are multiplied by the same factor k, i.e.

r'=kr

l'=kl

The new surface area is

SA'=\pi r'^2+\pi r' l'=\pi (kr)^2+\pi \cdot kr\cdot kl=k^2\pi r^2+k^2\pi rl

SA'=k^2(\pi r^2+\pi rl)=k^2\cdot SA

The new surface area is the  k ^2 times original SA. Since k=2/3, then

SA'=4/9\ SA

The surface area is multiplied by 4/9.
