f(x) =2x-4 and g(x) =-3x+2 find: f(g(x))

Answers

Answer:

f(g(x))=6x-8

Step-by-step explanation:

To keep it simple lets say if , for example

[tex]f(x)=2x-4[/tex]

then f(2) would be what?

[tex]f(2)=2(2)-4\\f(2)=0[/tex]

which means we plugged in x=2 in our f(x) this goes for same as the composite function [tex]f(g(x))[/tex] where we plug in g(x) in f(x) and replace x with g(x). I'll show you

[tex]f(x)=2x-4\\g(x)=-3x+2\\[/tex]

now we insert g(x) in f(x) cause we need f(g(x)) which means we replace x with the function g(x).

[tex]f(g(x))=-2(-3x+2)-4[/tex]

[tex]f(g(x))=6x-4-4\\f(g(x))=6x-8[/tex]

so that is our final answer.

Answer:

y=arcsinx and y=arctanx

Step-by-step explanation:

The functions that are symmetric with respect to the origin will be y = arcsin x and y = arctan x. Then the correct option is D.

What is a function?

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

Simply put, inverse trigonometric operations are the opposites of the fundamental trigonometric parameters sine, cosine, secant, cosecant, tangent, and cotangent.

Axial symmetrical is similarity around an axis; an item is internally symmetric if it retains its appearance when turned around an axis.

The functions that are symmetric with respect to the origin will be y = arcsin x and y = arctan x. Then the correct option is D.

Answers

Answer:

Mean = 3.9

Step-by-step explanation:

Given

The above table

Required

Determine the mean

The mean is calculated as thus:

Mean = Summation of x * P(x)

So, we have:

Mean = 1 * 0.14 + 2 * 0.16 + 3 * 0.12 + 4 * 0.14 + 5 * 0.13 + 6 * 0.31

Mean = 0.14 + 0.32 + 0.36 + 0.56 + 0.65 + 1.86

Mean = 3.89

Mean = 3.9 (approximated)

The mean should be 3.9.

Calculation of the mean;

Here the following formula should be used:

Mean = Summation of x * P(x)

So,

Mean = 1 * 0.14 + 2 * 0.16 + 3 * 0.12 + 4 * 0.14 + 5 * 0.13 + 6 * 0.31

= 0.14 + 0.32 + 0.36 + 0.56 + 0.65 + 1.86

= 3.89

= 3.9

Therefore, we can conclude that The mean should be 3.9.

Correct answer receives BRAINLIEST! Have a great day. ❤️

Using the concept of x-intercept, it is found that the correct statement is:

The x-intercept of the function f is greater than the x-intercept of function g.

What is the x-intercept of a function?The x-intercept of a function is the value of x when y = 0.

In this problem, in function f(x), when f(x) = 0, x = 3, hence the x-intercept is x = 3.

Function g(x) is defined by:

[tex]g(x) = 2 + \sqrt[3]{3x + 1}[/tex]

Hence, the x-intercept of g(x) is found as follows:

[tex]g(x) = 0[/tex]

[tex]2 + \sqrt[3]{3x + 1} = 0[/tex]

[tex]\sqrt[3]{3x + 1} = -2[/tex]

[tex](\sqrt[3]{3x + 1})^3 = (-2)^3[/tex]

[tex]3x + 1 = -8[/tex]

[tex]3x = -9[/tex]

[tex]x = -\frac{9}{3}[/tex]

[tex]x = -3[/tex]

The x-intercept of g(x) is -3, which is less than the x-intercept of function f(x), hence, the correct statement is:

The x-intercept of the function f is greater than the x-intercept of function g.

А At a concessan stand l hot dog and one hamburger cost $4.One hotdog and
5
Hamburgers cost $13
Find the cost of one hot dog and the cost of one hamburger ?

Answers

Answer:

2.25

Step-by-step explanation:

let x be cost of a hotdog

let y be cost of hamburger

 

so,

 

5x + 4y = 17.75                    eq. 1

4x + 5y = 18.25                    eq. 2

 

manipulate eq. 1 so solve for x:

 

5x = 17.75 - 4y

 

x = 17.75/5 - (4/5)y

 

x = 3.55 - (4/5)y                  eq. 3

 

substitute eq. 3 to eq. 2:

 

4(3.55 - (4/5)y) + 5y = 18.25

 

14.2 - (16/5)y + 5y = 18.25

 

14.2 + (9/5)y = 18.25

 

(9/5)y = 18.25 - 14.2

 

4.05= (9/5)y

 

y = 2.25

 

x = 3.55 - (4/5)(2.25)

 

x = 1.75

 

hotdog costs $1.75

hamburger costs $2.25

2/15 = h/125 need a step by step please

Answers

Answer:  h = 50/3

====================================

Work Shown:

2/15 = h/125

2*125 = 15*h .... cross multiply

250 = 15h

15h = 250

h = 250/15

h = (5*50)/(5*3)

h = 50/3

-----------------

Extra info:

50/3 = (48+2)/3

50/3 = (48/3)+(2/3)

50/3 = 16 + (2/3)

50/3 = 16 & 2/3

The improper fraction 50/3 converts to the mixed number 16 & 2/3

Another way to see this is to use long division to get 50/3 = 16 remainder 2.

Answers

Complete question is;

In a recent poll of female college students, 70% stated that they plan to graduate with a STEM degree. A math teacher at ODU decides to randomly sample 15 female college students. Find the standard deviation for the number of female college students out of 15 that plan to graduate with a STEM degree.

Answer:

σ = 1.77

Step-by-step explanation:

We are told that 70% stated that they plan to graduate with a STEM degree.

This means that probability of success is; p = 70% = 0.7

A sample of 15 female college students were randomly selected, this means that number of trials is;

n = 15

Now,in binomial distribution formula for standard deviation is;

σ = √(np(1 - p))

Plugging in the relevant values, we have;

σ = √(15 × 0.7 × (1 - 0.7))

σ = √(15 × 0.7 × 0.3)

σ = √3.15

σ ≈ 1.77
