y is directly proportional to x. When y = 30, x = 6 a) Work out an equation connecting y and x. b) Work out the value of y when x = 12.​

Answers

Answer 1
Answer:
y=5x (your equation)

y=60 (your answer)

Step by step explanation:
You are given two numbers, 6 and 30. Since 6 goes into 30, 5 times, then y(which is equal to 30) is equal to x(which is equal to 6) multiplied by 5, so you get your equation,

Y=5X

then you have to solve for y, so just substitute

Y=5(12)

And simplify

Y=60

And there’s your answer

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]

Which of the following rational functions is graphed below?

Answers

Have you gotten your answer yet?

I'm pretty sure the answer is C, I'm not sure though.

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.

Linear function is a function whose graph is a straight line

We are given that;

The graph of the function

Now,

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.

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
