The rational function which is graphed below is  F(x)=1/x, the correct option is A.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Points on 4/x

The function y = 4/x is a hyperbola. It has two branches that extend infinitely in opposite directions. The x-axis and y-axis are both asymptotes of the hyperbola.

On y= 1/x-4

The function y = 1/(x - 4) is also a hyperbola. Its asymptotes are the vertical line x = 4 and the horizontal line y = 0.

On y = 1/(x + 4)

The function y = 1/(x + 4) is also a hyperbola. Its asymptotes are the vertical line x = -4 and the horizontal line y = 0.

Therefore, by the given graph function will be F(x)=1/x.

work out a and b

I dont really care about the answer I just want the working out and the reason why​

Answers

Answer:

a=5 b=8

Step-by-step explanation:

[tex] {(a {r}^{b} )}^{3} = 125 {r}^{24} [/tex]

[tex] {(a {r}^{b} )}^{3} = {5}^{3} {r}^{24} [/tex]

{125 = 5×5×5 = 5³}

[tex]{(a {r}^{b} )}^{3} = {(5 {r}^{8}) }^{3} [/tex]

{Taking 3 power outside to get 5r⁸}

{Then match the positive integer with a and b}

A small school has 78 students. If 24 students are boys what is the ratio of girls to boys​

Answers

54:24
Explanation:
If there’s 78 students, and you subtract 24, you’re left with 54, therefore your answer would be 54:24

Answer:

54 : 24

Step-by-step explanation:

Total: 78 students

Part (boys): 24 students

We can find the number of girls in the school by subtracting the number of boys from the total number of students.

Part (girls): Total - Part (boys) = 78 - 24 = 54

We now have the amount of girls and boys, so we can rewrite as a ratio of girls to boys.

Girls: 54

Boys: 24

Girls : Boys = 54 : 24

You have a pile of 45,000 candies. You are going to give away 18% every day. USING THE EXPLICIT EQUATION how many candies will you have left after 5 days. Round you answer to the nearest whole candy

Answers

Answer:

16683 candies

Step-by-step explanation:

Given:

Initial value is 45000.Reduction per day is 18%.

The equation would be:

[tex]C(t) = 45000*(1 - 0.18)^t=45000*0.82^t[/tex], where C(t) is the number of candies left after t days

Find the value of C(5):

C(5) = 45000*0.82⁵ ≈ 16683 rounded

[tex]\\ \sf\longmapsto C(t)=P\left(1-\dfrac{R}{100}\right)^t[/tex]

[tex]\\ \sf\longmapsto C(t)=45000\left(1-\dfrac{18}{100}\right)^t[/tex]

[tex]\\ \sf\longmapsto C(t)=45000(1-0.18)^t[/tex]

[tex]\\ \sf\longmapsto C(t)=45000(0.82)^t[/tex]

Now

[tex]\\ \sf\longmapsto C(5)=45000(0.82)^5[/tex]

[tex]\\ \sf\longmapsto C(5)=45000(0.37)[/tex]

[tex]\\ \sf\longmapsto C(5)\approx16650[/tex]

To find the distance between two points in the coordinate plane, you must use the distance formula, which is [tex]\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1})^{2}}[/tex], and substitute the points into the formula.

[tex]\sqrt{(24-24)^{2}+(-4-14)^{2} }[/tex]

45% of the rooms in a hotel are booked. If 36 rooms are booked, how many rooms are in a hotel altogether?

Answers

Answer:

80 rooms

Step-by-step explanation:

since 45% of the rooms are booked, and 36 rooms are booked, then this means that 36 = 45% of x.

then, you we have 45% × x = 36

or [tex]\frac{45}{100}[/tex]  × x = 36

Multiplying both sides by 100 and dividing both sides by 45,

we have x = 36 ×  [tex]\frac{100}{45}[/tex]

= [tex]\frac{3600}{45}[/tex]  

x = 80
