Answer:
D. [tex]x\geq 0[/tex]
Step-by-step explanation:
In order to answer this question we need to know the definition of the domain. The domain of a function is the complete set of possible values of the independent variable ("x"). In our case we can look at the function and cross out option "A" because the function has no point with a negative "x" value. Option "B" can be also crossed out because it states that "x" values can not go above 3 but by looking at the function we can see multiple point with "x" values larger then 3. Option "C" can also be crossed out because their is not point on the function that would have a negative "x" value which contradicts the statement about all numbers. And finally we are left with "D" and we know it is the right answer since the function has a point with "x" value being equal to 0 and the all other points have the "x" value greater then 0, which is exactly what option "D" states.

A stereo speaker in the shape of a triangular pyramid has a height of 6 inches. The area of
the base of the speaker is 11 square inches.
What is the volume of the speaker in cubic inches?
Answers
Answer:
[tex]V=22\ \text{inches}^3[/tex]
Step-by-step explanation:
Given that,
Height of a triangular pyramid = 6 inches
The area of the base of the speaker is 11 square inches
We need to find the volume of the speaker.
The formula for the volume of triangular pyramid is given by :
[tex]V=\dfrac{1}{3}Ah[/tex]
A is area of base and h is height
[tex]V=\dfrac{1}{3}\times 11\times 6\\\\=22\ \text{inches}^3[/tex]
So, the volume of the speaker is [tex]22\ \text{inches}^3[/tex].

The volume of a single layer in a rectangular prism is 9 cubic centimeters. There are 6 layers in the rectangular prism. What is the total volume, in cubic centimeters, of the rectangular prism?
Answers
Answer:
Total volume of the rectangular prism = 54 cubic centimeters
Step-by-step explanation:
Volume of a single layer in a rectangular prism = 9 cubic centimeters
There are 6 layers in the rectangular prism
What is the total volume, in cubic centimeters, of the rectangular prism?
Total volume of the rectangular prism = Volume of a single layer in the rectangular prism × number of layers in the prism
= 9 cubic centimeters × 6 layers
= 54 cubic centimeters
Total volume of the rectangular prism = 54 cubic centimeters
The winning time for the men's 400-meter race in each of the Olympic Games from 1976 to 1996 can be modeled by the equation y = −0.054x + 44.54 , where x is the number of years after 1976 and y is the winning time in seconds. If the relationship continues, which equation could be used to predict the winning time in the year 2020?
Answers
Answer:
D. y = −0.054(44) 44.54
Step-by-step explanation:
The difference in years from 1976 to 1996 is 20 years
But from 1976 to 2020 the years would be 44
So here put the value of x as 44
Therefore the equation that could be used for predict the winning time for the year 2020 is y = −0.054(44) 44.54
Hence, the correct option is d.
ANd the rest of the options are incorrect

Please Help Me Thank you :)
Answers
Answer:
(5, 0)
Step-by-step explanation:
For the first line, we can isolate x by subtracting 5y on both sides.
x=5-5y.
Now we can use substitution on the second line!
-(5-5y)+6y=-5
= -5+5y+6y=-5
=-5+11y=-5
=11y=0
y=0
We subsitute y for the first line,
x+5(0)=5
x+0=5
x=5
We can check our work by plugging in x and y
5+5(0)=5 ✔
-5+6(0)=-5 ✔

The air conditioning unit for marcus building has the shape of a cube and has a volume of 0.512 cubic meters.This air conditioner will be replaced with another cube-shaped unit with a volume of 1 cubic meter. By how much will the edge length of the air conditioner change?
Answers
Answer:
The edge length of the air conditioner changed by 0.2m
Step-by-step explanation:
The volume of a cube is S^3
The edge length of the former unit is cube root of 0.512 which is 0.8 m
The edge length of the new is cube root of 1 which is 1 m
The difference is 1-0.8 = 0.2 m

Ms. Raab and Ms. Levy both drink coffee in the
mornings.
Ms. Raab adds 1 more teaspoon to each cup of
coffee than Ms. Levy. Together, they both add 5
teaspoons of sugar to their coffees.
How many teaspoons of sugar does Ms. Raab add?
How many teaspoons does Ms. Levy add?
Set up an equation to show this, and then solve.
Answers
Answer:
Ms Levy = 2
Ms Rabb = 3
Step-by-step explanation:
Let :
Number of teaspoons taken by Ms Levy = x
Number of teaspoons taken by Ms Rabb = x + 1
Total number of teaspoons taken by both = 5
(Number of teaspoons taken by Ms Rabb + Number of teaspoons taken by Ms Levy) = total number of teaspoons taken
x + 1 + x = 5
2x + 1 = 5
2x = 5 - 1
2x = 4
x = 4/2
x = 2
Hence,
Number of teaspoons of sugar added by Ms Levy = x = 2
Number of teaspoons of sugar added by Ms Rabb = x + 1 = 2 + 1 = 3

The equation that represents the graph of the function g(x) is g(x) = f(x + 3) - 2
How to determine the function g(x)?The equation of the function f(x) is given as:
f(x) = x^3
The function g(x) is shifted down by 2 units and shifted left by 3 units, to get the function g(x)
This means that:
g(x) = f(x + 3) - 2
So, we have:
g(x) = f(x + 3) - 2
Hence, the equation that represents the graph of the function g(x) is g(x) = f(x + 3) - 2
