what is the range and domain of a cube root function
Answer:
Domain: (-infinity, infinity), Range: (-infinity, infinity)
Step-by-step explanation:
This is an odd function. The graph passes through (0, 0), starting in Quadrant 3 and continuing into Quadrant 1.
There is a point on the graph for every input value, and so the domain of the cube function is (-infinity, infinity). Similarly, the range is (-infinity, infinity).
The range and domain of a cube root function are [0, ∞).
What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
The domain is for the independent variable while the range is for the dependent variable.
For example f(x) = x²
Now if we put x = 1 then it is called as domain variable while the value of function at x = 1 its that f(1) = 1 called range variable.
Cube root function is given as;
y = [tex]x^{1/3}[/tex]
Now as x increases (x > 0) y is also increasing although slower to x then still it is increasing.
So,
x → ∞ ⇒ y → ∞
For x < 0 it will become an imaginary number so it will not be defined.
Hence "The range and domain of a cube root function are [0, ∞)".

Find all constants α such that the vectors (α, 4) and (α, 5) are parallel.
Answer:
[tex]\alpha_{2} = \frac{5}{4}\cdot \alpha_{1}[/tex], for all [tex]\alpha_{1} \in \mathbb{R}[/tex]
Step-by-step explanation:
Vectors are parallel to each other if:
[tex]\vec u = \beta \cdot \vec v[/tex]
[tex](\alpha_{2}, 5) = (\beta\cdot \alpha_{1}, \beta \cdot 4)[/tex]
The value of [tex]\beta[/tex] is:
[tex]\beta = \frac{5}{4}[/tex]
Then, the following relationship is found:
[tex]\alpha_{2} = \frac{5}{4}\cdot \alpha_{1}[/tex], for all [tex]\alpha_{1} \in \mathbb{R}[/tex]

Answer with Step-by-step explanation:
a.If the circle has circumference of [tex]6\pi[/tex] in,then it has a diameter of 3 in.
Circumference of circle=[tex]6\pi[/tex]in
We know that
Circumference of circle=[tex]2\pi r[/tex]
Using the formula
[tex]6\pi=2\pi r[/tex]
[tex]r=\frac{6\pi}{2\pi}=3[/tex]in
Diameter of circle=[tex]2\times 3=6[/tex]in
It is false.
b.f the circle has diameter of 2 inches,then it has a circumference of 6.28 in.
Diameter,d=2 in
Circumference of circle=[tex]\pi d=3.14 \times 2=6.28[/tex]in
It is true.
c.If the circle has a circumference of [tex]2\pi[/tex]in then it has an area [tex]\pi[/tex] square inches.
Circumference=[tex]2\pi[/tex]in
[tex]2\pi r=2\pi[/tex]
[tex]r=\frac{2\pi}{2\pi}=1[/tex]in
Area of circle=[tex]\pi r^2=\pi(1)^2=\pi in^2[/tex]
It is true.
d.If the circle has a circumference of [tex]\pi[/tex]in then it has an area [tex]0.5\pi[/tex] square inches.
Circumference=[tex]\pi[/tex]in
[tex]2\pi r=\pi[/tex]
[tex]r=\frac{\pi}{2\pi}=\frac{1}{2}in[/tex]
Area of circle=[tex]\pi(\frac{1}{2})^2=0.25\pi in^2[/tex]
It is not true.
e.If the circle has a radius of 1.5 inches,then it has an area of 7.065 square inches.
Radius,r=1.5 in
Area of circle=[tex]3.14\times (1.5)^2=7.065in^2[/tex]
It is true.

It takes Carol 45 minutes to drive to work using two roads. She drives 24 mph on a small road for hour. Then she drives 56 mph on a highway for hour. How far does Carol travel to work?
Answer:
She travels 30 miles for work.
Given,
Total time = 45 minutes
Speed on small world = 32mph
Time on small world = 1/2 hour
Distance = Speed * time =
Distance on small world = 16 miles
Speed on small road = 56mph
Time on small road = 1/4 hour
Distance on small road =
Distance on small road = 14 miles
Total distance = Distance on small world + Distance on small road
Total distance = 16+14= 30 miles
She travels 30 miles for work.
Keywords: Distance, speed
Step-by-step explanation:
Final answer:
Carol travels 12 miles on the small road and 28 miles on the highway, totaling 40 miles to get to work.
Explanation:
The question asks us to calculate the total distance Carol travels to work using two different speeds on two different roads. To solve this problem, we use the formula d = vt, where d represents distance, v is velocity (or speed), and t is time.
On the small road, Carol drives at 24 miles per hour for half an hour (0.5 hours). Therefore, the distance traveled on the small road is:
d = (24 miles/hour)(0.5 hours) = 12 miles
On the highway, she drives at 56 miles per hour for half an hour (0.5 hours) as well. The distance traveled on the highway is:
d = (56 miles/hour)(0.5 hours) = 28 miles
To find the total distance, we add the distances from both roads:
Small road: 12 milesHighway: 28 milesTotal distance = 12 miles + 28 miles = 40 miles
Carol travels a total of 40 miles to get to work.

Step-by-step explanation:
Numbers that have a star and a circle on them are all multiples of 3 and 7. As there are less multiples of 7 between 1-100 we should list the multiples of 7 and then check if they are also multiples of 3.

Which equation represents:
"An unknown integer, multiplied by the unknown integer minus a different unknown integer, equals 100."
A) x2 + xy + 100 = 0
B) x2 + xy − 100 = 0
C) x2 − xy + 100 = 0
D) x2 − xy − 100 = 0
Answer:
D) x² − xy − 100 = 0
Step-by-step explanation:
You want an expression for "An unknown integer, multiplied by the unknown integer minus a different unknown integer, equals 100."
SetupLet x represent the unknown integer, and y represent the different unknown integer. Their difference will be (x -y). When that is multiplied by x and the result equal to 100, we have ...
x(x -y) = 100
SimplifyEliminating parentheses using the distributive property, we have ...
x·x -x·y = 100
x² -xy = 100
Subtracting 100 gives an expression equal to zero:
x² -xy -100 = 0 . . . . . . . matches choice D
What are the domain and range of f(x) = 2|x – 4|? domain: x <= 2; range: (-infinity,infinity) domain: (-infinity,infinity); range: f(x)>= 0 domain:(-infinity,infinity); range: f(x) <= 0 domain: x>= 2; range: (-infinity,infinity)
Answer:
domain: (-infinity,infinity);
range: f(x)>= 0
Step-by-step explanation:
f(x) = 2|x – 4|
The domain is the input values or the values that x can take
We can use any value we want for x
Domain: -infinity to infinity
The range is the output values
Since it is an absolute value, the smallest value it can take is 0, it can increase as large as it wants
Range: 0, infinity
Solve for x
Your answer must be simplified.
x/-6 ≥−20
Answer: x ≤ 120
Step-by-step explanation: To get x by itself in this inequality, since it's being divided by -6, we must multiply both sides by -6 just like we would if we were solving an equation.
But here is the trick you have to
watch out for with inequalities.
When you multiply or divide both sides of an inequality by a
negative, you must switch the direction of the inequality sign.
So our second step in this problem reads x ≤ 120.
Please give this idea your full attention. Even the most advanced algebra students will sometimes forget to switch the direction of the inequality sign when multiplying or dividing both sides of an inequality by a negative.

Work out the percentage change when a price of £65 is decreased to £39.
Answer:
40% decrease
Step-by-step explanation:
Say the percent decrease is x%. Then, we can write the equation:
65 - x% * 65 = 39
Notice that 65 is a common factor of both terms on the left, so factor that out:
65 * (1 - x%) = 39
Divide by 65 on both sides:
1 - x% = 0.6
Subtract 0.6 from and add x% to both sides:
x% = 0.4
Remember that % simply means "out of 100", so x% = x/100:
x/100 = 0.4
Multiply by 100:
x = 40
So the percentage decrease is 40%, or the percent increase is -40% (whichever way the question asks).
Hope this helps!
Answer:
p = 40%
Step-by-step explanation:
65 - p%65 = 39
65 - 65p/100 = 39
6500 - 65p = 3900
6500 - 3900 = 65p
65p = 2600
p = 2600 : 65
p = 40%
A bag contains 4 red marbles and 1 yellow marble. What is the probability of drawing a red marble, then replacing that marble, then drawing a red marble again on the second pick?
Answer:
16/25
Step-by-step explanation:
We have 4 red marbles and a total of 4 + 1 = 5 marbles.
Probability is simply (# times a specific event can occur) / (# times any event can occur).
Here, the probability of drawing a red marble is: 4/5 (because there are 4 red marbles to choose from and a total of 5 marbles to choose from).
We replace the marble afterward, so the probability that the second pick is also red would still be 4/5.
Then, multiply the two fractions together: (4/5) * (4/5) = 16/25.
Hope this helps!
