I'm not sure but i believe is that one
The best definition of the term "reciprocal" is: A fraction that is the multiplicative inverse of the given fraction. The correct option is option B
What is fraction reciprocal?The reciprocal of a fraction is obtained by swapping the numerator and the denominator of the fraction. It is a number that, when multiplied by another number, results in a product of 1. For example, the multiplicative inverse of 2 is 1/2, because 2 × 1/2 = 1. In general, if a number "a" has a multiplicative inverse "b," then a × b = 1. However, not all numbers have multiplicative inverses.
Reciprocals are also knowns as multiplicative inverse. Multiplicative inverses are essential in various mathematical operations and concepts, including fractions and solving equations involving division.

A polynomial of degree at least 3 where one or more of the roots are fractions
#1 p(x)=(x-3)*(x-5)*(x-1)=x3-9x2+23x-15
You try the next one...a fractional root would look like (x-3/2)
Using the Factor Theorem, it is found that an example of a polynomial of degree at least 3 where one or more of the roots are fractions is given by:
[tex]f(x) = x^3 - \frac{7}{2}x^2 + \frac{1}{2}x - 1[/tex]Factor Theorem: The Factor Theorem states that a polynomial function with roots [tex]x_1, x_2, \codts, x_n[/tex] is given by:[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]
In which a is the leading coefficient.In this problem:
A polynomial of degree 3 will be built, hence it will have 3 roots.A leading coefficient of a = 1 is supposed.Two non-fractional roots, which are x = 1 and x = 2, hence [tex]x_1 = 1, x_2 = 2[/tex].The fractional root is [tex]x_3 = \frac{1}{2}[/tex].Hence:
[tex]f(x) = (x - x_1)(x - x_2)(x - x_3)[/tex]
[tex]f(x) = (x - 1)(x - 2)\left(x - \frac{1}{2}\right)[/tex]
[tex]f(x) = (x^2 - 3x + 2)\left(x - \frac{1}{2}\right)[/tex]

Use the given information to write an equation of each parabola:
The parabola has focus (0,6) and vertex at the origin.
The equation of the parabola is:

---------------------------
The equation of a parabola of vertex (h,k) and focus (0,f) is given by:
[tex]y = 4p(x - h)^2 + k^2[/tex]
Vertex at the origin means that [tex]h = 0, k = 0[/tex].Focus (0,6) means that [tex]p = 6[/tex]Thus, the equation of the parabola is:
[tex]y = 4p(x - h)^2 + k^2[/tex]

Please answer #11,#15,and #16.For #11, determine if the graph represents a function.For #15-16 find the domain and range of the function represented by the graph.
Problem 11
Answer: Not a function
Why not? Because it fails the vertical line test. It is possible to draw a single straight vertical line through more than one point on this blue curve.
Put another way: An input like x = 2 produces more than one output (y = 2 and y = 4 at the same time). If we wanted a function, we need any given input in the domain to produce exactly one and only one output.
=============================================================
Problem 15
Answers:
Domain: [tex]-4 \le x \le 2[/tex]Range: [tex]2 \le y \le 6[/tex]Explanation:
The domain is the set of allowed x values. The left-most point on the blue curve is when x = -4, which is the smallest item allowed in the domain. The largest value allowed is x = 2, as this occurs at the right-most point on the blue curve. Therefore, our domain here is [tex]-4 \le x \le 2[/tex]
The range is similar, but we focus on y values this time. The lowest the graph goes is y = 2, and the highest it goes is y = 6. So [tex]2 \le y \le 6[/tex] represents the range of possible y outputs.
For both the domain and range, both endpoints are included.
=============================================================
Problem 16
Answers:
Domain: [tex]2 < x < 7[/tex]Range: [tex]1 < y < 6[/tex]Explanation:
We follow the same idea as before. This time however, we have open holes which means that we do not include the endpoints.
The domain is [tex]2 < x < 7[/tex] since the curve spans from x = 2 to x = 7, excluding both of those x values. The range is [tex]1 < y < 6[/tex] for similar reasoning.
Notice how both problems 15 and 16 are functions because they pass the vertical line test. It is not possible to draw a single vertical line through more than one point on either blue curve.

The value of y varies directly with x. If x = 195 when y = 15, what is the value of x when y = 9?
Since the value of y varies directly with x, the value of x when y equals 9 is [tex]\frac{9}{13}[/tex]
Given the following data:
x = 195y = 15To find the value of x when y = 9:
This is a direction proportion exercise and you're required to solve for the value of x when the value of y is equal to 9.
First of all, we would determine the constant of proportionality (k) for the mathematical expression.
[tex]y = kx\\\\15 = 195k\\\\k = \frac{195}{15}[/tex]
k = 13
Now, we can find x:
[tex]y = kx\\\\9 = 13x\\\\x = \frac{9}{13}[/tex]
Therefore, the value of x when y equals 9 is [tex]\frac{9}{13}[/tex]

How much will nick and Adam weigh?
Answer:
181 pounds
Step-by-step explanation:
You have already got the equation and solution which is great! The next step is simply a matter of replacing "x" with "7", because you know x=7.
After doing this, you will be left with the equation 160+3*7=195-2*7. We will look at the first part of the equation first. Using the rules of BIDMAS, you can calculate 3*7=21 and then 160+21=181. 181 is your final answer.
You can check that this is right by calculating the second part of the equation, and once done you should be left with 181. Again, using BIDMAS, you need to do 2*7=14 then 195-14=181. Now we know that everything is correct.
