The domain of a function is all the possible input values for which the function is defined.
What is function?Function is a block of code that performs a specific task. It is a reusable piece of code that can be called from other parts of the code, reducing the amount of code that needs to be written and making the code easier to read and maintain. Functions can take in parameters and return values, allowing for increased flexibility and reusability. Functions can also be used to break up large programs into smaller, more manageable pieces.
In this case, the reasonable domain for the function f(x) = 4x³-50x²+150x would be all real numbers. This is because the function is a polynomial, which is continuous, meaning that it is defined for all real numbers.
The input of the function is a width, and the output is a volume. Therefore, the domain of the function should include all reasonable widths that could produce a volume. This means that the domain should include all positive real numbers, as any negative value would produce a negative volume, which is not reasonable. Thus, the reasonable domain for the function f(x) = 4x³-50x²+150x is all positive real numbers.

A beetle is 1/5 inch wide and 2/5 inch long.How much greater is the beetle’s length than it’s width?
Answer: To find how much greater the beetle's length is than its width, we need to subtract the width from the length:
Length - Width
Substituting the given values, we get:
2/5 inch - 1/5 inch
Simplifying the expression by finding the common denominator of 5, we get:
(2/5 - 1/5) inch
= 1/5 inch
Therefore, the beetle's length is 1/5 inch greater than its width.

Which of the following are solutions to the system of inequalities y<−x+5 and y≥3x+1? Select all that apply.
The only solution to the system of inequalities y < −x+5 and y ≥ 3x+1 is (1,3).
What are the inequalities?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
For the inequality y < -x + 5, any point below the line y = -x + 5 will satisfy the inequality. For the inequality y ≥ 3x + 1, any point on or above the line y = 3x + 1 will satisfy the inequality.
To find the solutions that satisfy both inequalities, we can shade the region that is below the line y = -x + 5 and also on or above the line y = 3x + 1. This region is the shaded triangle bounded by the lines y = -x + 5, y = 3x + 1, and the x-axis.
Therefore, the solutions to the system of inequalities are the points in this shaded triangle. To check which options are solutions, we can substitute the values of x and y given in each option into both inequalities and check if they satisfy both.
(0,2): y < -x + 5 is true because 2 < -0 + 5. y ≥ 3x + 1 is false because 2 < 3(0) + 1. Therefore, (0,2) is not a solution.(1,3): y < -x + 5 is true because 3 < -1 + 5. y ≥ 3x + 1 is true because 3 ≥ 3(1) + 1. Therefore, (1,3) is a solution.(2,1): y < -x + 5 is true because 1 < -2 + 5. y ≥ 3x + 1 is false because 1 < 3(2) + 1. Therefore, (2,1) is not a solution.(3,6): y < -x + 5 is false because 6 ≥ -3 + 5. y ≥ 3x + 1 is true because 6 ≥ 3(3) + 1. Therefore, (3,6) is not a solution.Hence, the only solution is (1,3).

Gwen has $800 in a savings account that earns 10% annually. The interest is not compounded .How much interest will she earn in 1 year?
g(n)=−50−15n. complete the recursive formula of g(n).
Answer: To complete the recursive formula for g(n) = -50 - 15n, we need to find an expression for g(n) in terms of previous terms of the sequence.
One way to do this is to notice that g(n) can be obtained by subtracting 15 from the previous term, g(n-1):
g(n) = -50 - 15n
= -50 - 15(n-1) - 15 (adding and subtracting 15)
= g(n-1) - 15
Therefore, the recursive formula for g(n) is:
g(0) = -50 (base case)
g(n) = g(n-1) - 15 (recursive step)
This means that to find g(n), we need to first find g(n-1) and then subtract 15 from it. We can use this recursive formula to generate any term in the sequence of g(n).

Answer:
x = 100
y = 100
z = 80
Step-by-step explanation:
The properties of a rhombus are:
All sides are equal in length.The opposite sides are equal and parallel.Opposite angles are congruent.Adjacent angles are supplementary (sum to 180°).Two angles are said to be adjacent when they share a common vertex.
Therefore, both angle x and angle y are adjacent to the angle that measures 80°.
Since adjacent angles in a rhombus are supplementary:
⇒ x° + 80° = 180°
⇒ x° = 100°
⇒ x = 100
Similarly:
⇒ y° + 80° = 180°
⇒ y° = 100°
⇒ y = 100
As opposite angles in a rhombus are equal:
⇒ z° = 80°
⇒ z = 80

Therefore , the solution of the given problem of function comes out to be the ball can reach a height of 74 feet, to the closest foot.
What is meant by the word function?The study of mathematics includes topics such as numbers, symbols, and their component components, as well as anatomy, building, and that both true and fictitious geographic locations. A function describes the relationships between different components that all lead to the same result. A function is made up of several variable distinct components that, when placed together, produce specific outputs for every input.
Here,
The starting height (h0) is 4 feet, and the initial speed (v0) is 75 feet per second.
The ball's vertical movement is modelled by the formula h(t) = 16t2 + v0t + h0.
When we change the numbers, we obtain:
h(t) = −16t2 + 75t + 4
The vertex of the parabolic function marks the height of the spheroid at its greatest height.
The vertex's t-value is determined by:
t = −v0/2a
where a represents the t2 component in the h-function (t).
When we change the numbers, we obtain:
t = −75/(2(−16)) = 2.34375
2.34375 seconds pass after the ball is thrown before it hits its highest point.
Given is the utmost height:
h(2.34375) = −16(2.34375) (2.34375)
2 + 75(2.34375) + 4 = 74 feet

10. Given that xy = a², show that + a+x a+y
Employing the identity (a+b)² = a² + 2ab + b², where a and b are any real numbers.
Substituting a and b with a and x/y, respectively:
(a + x/y)² = a² + 2a(x/y) + (x/y)²
(a + x/y)² = (a + x/y)(a + x/y)
= a² + ax/y + ax/y + x²/y²
= a² + 2ax/y + x²/y²
add a² to both sides of the equation:
a² + (a + x/y)² = a² + 2ax/y + x²/y² + a²
a² + (a + x/y)² = (a² + x²/y²) + 2ax/y + a²
xy = a² substitute a² for xy in the last term:
a² + (a + x/y)² = (a² + x²/y²) + 2axy/xy + a²
a² + (a + x/y)² = (a² + x²/y²) + 2a + a²
We have that x²/y² = (xy)/(y²) = a/y, and substituting this back into the equation:
a² + (a + x/y)² = (a² + a/y + a/y) + 2a + a²
= 2a² + (2a/x) + (2a/y)

A) y = 5 + x
B) y = 4x
C) y = 7x²
D) y = 2 - x
The equation which represents a proportional relationship from the given set of equations is y = 4x.
What is meant by a proportional relationship?
Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportional relationship, one variable is consistently equal to the other's constant value. y= k x, where k is the proportionality constant, is the equation that depicts a directly proportional relationship, or a line. y = k(1/x) or xy = k, where k is the proportionality constant, is the equation that depicts an indirectly proportional relationship, or a line. One can argue that two variables are in a proportional relationship if one variable is always equal to a constant multiplied by the other variable.
So according to the above explanation, we can say that the equation y = 4x is an example of a proportional relationship.
This is because the ratio y/x is always a constant 4.
Therefore the equation which represents a proportional relationship is y = 4x.
