Which graph represents the function f(x) = 4x

Answers

Answer:

[tex]\boxed{\textsf{ The required graph of y = 4x will be a straight line passing through the origin . }}[/tex]

Step-by-step explanation:

Here we need to plot the graph for the function given to us . The function is ,

[tex]\sf \implies f(x)= 4x [/tex]

In order to plot a graph let us assume that ,

[tex]\sf\implies y = f(x) [/tex]

Hence we now get , that ,

[tex]\sf\implies y = 4x [/tex]

Now let's find out some values of x and y taking which we will plot the graph .

• So , firstly let , x = 0 then y will be equal to 4*0 = 0 . Hence we got one coordinates as (0,0) .

• Secondly let x = 1 , then y will be equal to 4*1 = 4 . Hence we get the third coordinate as (4,0) .

• Thirdly let us take that x = 0.5 then y will be equal to 4*0.5 = 2 . Hence we got the third coordinate as ( 0.5 , 2 )

• Fourthly let x = -0.5 then y will be equal to 4*-0.5 = -2 . Hence the fourth coordinate will be (-0.5 , -2)

Now when we plot it's graph taking suitable scale then it will look something like that as shown in attachment .

For the graph of y = 4x kindly refer to the attachment :) .

★Hence the graph of y = 4x will be a straight line passing through the origin.

What is the area of the parallelogram?

Answers

Answer:

Step-by-step explanation:

The midpoint of AD is C. The midpoint of AC is B. If A is at (-10,4) and D is at (2,12), find the coordinates of B. Group of answer choices (-5,5) (-4,8) (-2.5,9) (7,6)

Answers

Answer:

[tex]B(x,y) =(-7,6)[/tex]

Step-by-step explanation:

Given

[tex]A = (-10,4)[/tex]

[tex]D = (2,12)[/tex]

Required

Determine the coordinates of B

C is the midpoint of AD. So, we calculate the coordinates of C, first.

[tex]C(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Where:

[tex]A = (-10,4)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]D = (2,12)[/tex] --- [tex](x_2,y_2)[/tex]

So, we have:

[tex]C(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

[tex]C(x,y) = (\frac{-10+2}{2},\frac{4+12}{2})[/tex]

[tex]C(x,y) = (\frac{-8}{2},\frac{16}{2})[/tex]

[tex]C(x,y) = (-4,8)[/tex]

So, the coordinates of C is (-4,8)

The midpoint of AC is B.

So, we calculate the coordinates of B using:

[tex]B(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Where:

[tex]A = (-10,4)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]C(x,y) = (-4,8)[/tex] --- [tex](x_2,y_2)[/tex]

So, we have:

[tex]B(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

[tex]B(x,y) =(\frac{-10-4}{2},\frac{4+8}{2})[/tex]

[tex]B(x,y) =(\frac{-14}{2},\frac{12}{2})[/tex]

[tex]B(x,y) =(-7,6)[/tex]

Hence, the coordinates of B is (-7,6)

None of the options is correct.

A movie theater has a seating capacity of 385. The theater charges $5.00 for children, $7.00 for students, and $12.00 of adults. There are half as many adults as there are children. If the total ticket sales was $ 2794, How many children, students, and adults attended?

Answers

Answer:

Step-by-step explanation:

The number of children is 198, adults are 99 and students are 88.

What is word problem?

A word problem is a few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

Given that, the theatre sitting capacity is 385 and the theatre charges are $5.00 for children $7.00 for students, and $12.00 for adults.

Let the number of children be c, since, there are half as many adults as there are children therefore, number of adults = c/2

The number of students = 385 - c - c/2 = 385 - 3c/2

The total cost  = $2794

Therefore,

2794 = 5c+c/2×12+(385-3c/2)×7

2794 = 5c+6c+2695 - 21c/2

c = 198

Therefore, number of adults = 198/2 = 99

The number of students = 385-3/2×198 = 88

Hence, The number of children is 198, adults are 99 and students are 88.

Melvin is pushing a tire during workout with the dimensions shown how many square inches of space has a tire covered after Melvin pushes the tire 5 times around

Answers

Answer:

The answer is below

Step-by-step explanation:

The question is not complete, but I would show you how to solve it.

Solution:

A circle is the locus of a point such that its distance from a fixed point which is its center is always constant.

The tire has the shape of a circle. Therefore the distance the tire covers if it is pushed around once is the same as the circumference of the tire. The circumference is given by:

Circumference = 2πr; where r is the radius of the tire

Let us assume that the tire has a radius of 7 cm. Hence:

Circumference = 2π(7) = 44 cm

If the tire moves around 5 times, the distance covered = 5 * circumference of tire = 5 * 44 cm = 220 cm
