How can the graph rule y=2x+1 be used to predict the result for an input (x-Value) of 7

Answers

Answer 1

The value of y for the given input x=7 is 15.

The given function is  y=2x+1.

We need to graph the given function.

How to graph the given function?

Graphing functions is the process of drawing the graph (curve) of the corresponding function. Graphing basic functions like linear, quadratic, cubic, etc is pretty simple, graphing functions that are complex like rational, logarithmic, etc, need some skill and some mathematical concepts to understand.

Now,

Graph the line using the slope and y-intercept, or two points.

Slope: 2

y-intercept: (0, 1)

Plot the points (0, 1) and (1, 3)

The value of y for x=7 is y=2(7)+1=15

Therefore, the value of y for the given input x=7 is 15.

A rectangular bathroom mirror has a perimeter of 24 feet and an area of 20 square feet. What are the dimensions of the mirror?

Answers

A rectangular bathroom mirror having a perimeter of 24 feet and an area of 20 square feet, The length and breadth of rectangle are 10 feet and 2 feet respectively.

Given,

perimeter of the rectangle = 24 feet

area of rectangle = 20 sq. feet

Formula of perimeter of rectangle = 2(L + B)

where L = length of the rectangle , Breadth of the rectangle.

24 = 2(L + b)                                  

⇒ 12 = L + B

⇒ L = 12 - B                                                  ........(1)

Formula of area of rectangle = L × B

20 = L × B                                      

⇒ L = 20 / B                                                  .......(2)

From (1) and (2)

equating two equations,

12 - B = 20 / B

⇒ 12B = 20 + B²

⇒ B² - 12B + 20

On solving,

B = 10, 2

So, the Length and breadth of rectangle are 10 feet and 2 feet

The value of the function f(x) = 2x/(2x + 3).

What is defined as the function?

A function is defined as a relationship between a set of inputs that each have one output.

A function is a connection between inputs in which each input is related to precisely one output. Every function does have a domain and a co-domain, as well as a range. In general, a function is denoted by f(x), where x is the input.

Now, as per the question, the functions are give as;

h(x) = (2x + 3)/x

g(x) = 2/x

And, g(f (x) ) = h(x) =  (2x + 3)/x  ......(equation 1)

To estimate the value of f (x); Substitute x for f(x)

g(f (x) ) = 2/f (x)     ......(equation 2)

Equation (equation 1 and 2).

2/f (x) =  (2x + 3)/x

f (x) = 2x/ (2x + 3)

Thus, the value of the function f (x) = 2x/ (2x + 3).

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such as printing). There are two production methods it could use.
With one method, the one-time will total $13,238, and the variable costs will be $24.75 per book.
With the other method, the one time fixed costs will total 50,107, and variable costs will be 11.75 per book. For how many books produced will the costs from the two methods be the same?​

Answers

2836 numbers books produced will the costs from the two methods be the same.

From the given data

There are two production methods could be used so we can get two equations for cost (c) from two methods

Let x be the numbers of books produced.

Now, To calculate the total production cost.

Total production cost by selling  books = Fixed one time cost + Cost for production of  books.

From method 1  the equation we get

C = 24.75x + 13238    

and from method 2 the equation we get

C = 11.75x + 50107

Method 1 cost = Method 2 cost

24.75x + 13238 = 11.75x + 50107

24.75x - 11.75x  = 50107 - 13238

13x = 36869

 x  = 36869/13

 x  = 2836

x = 2836 numbers of books will have same cost.

A zero-order reaction of reactant a is found to have [a]0=0.25 m. if [a]=0.10 m at t=100. s, what is the rate constant k?

Answers

The rate constant K is 0.0015.

Zero-order reaction of reactant a is found to have [a]0=0.25 m and

if [a]=0.10 m at t=100s, then we need to find the rate constant k.

What is the formula for rate constant k?

The rate constant, k, is a proportionality constant that indicates the relationship between the molar concentration of reactants and the rate of a chemical reaction

k=([a]0-[a])/t

where k is rate constant,

By the given data we have [a]0=0.25 m

[a]=0.10 m

t=100s

k=?

The rate constant, is a proportionality constant that indicates the relationship between the molar concentration of reactants and the rate of a chemical reaction.

The rate constant is denoted by k.

k=([a]0-[a])/t

Subtract 0.10 from 0.25 and divide it by 100

=(0.25-0.10)/100

=0.15/100

=0.0015

Therefore 0.0015 is the rate constant when a zero-order reaction of reactant a is found to have [a]0=0.25 m and [a]=0.10 m at t=100.

The point closest to -

the yz-plane is c(2, 9, 3).the xz-plane is  a(8, 0, 6).What is a plane in 3-D?

A plane is a two-dimensional flat surface that can extend indefinitely. A plane would be the two-dimensional equivalent of a point with zero dimensions, a line with one dimension, and three-dimensional space.

The equation is written on a three-dimensional plane is;

         ax+by+cz+d=0,

         where minimum one number out of a, b, and c must be non-zero.

In 3D coordinate space, a plane is defined by a point and a vector perpendicular to the plane.

Now, as per the question;

A point (x, y, zdistance )'s from the yz plane is equal to |x|.

As a result, for small |x|, the point would be closest to the yz plane.

C does have the smallest among A, B, and C that is |x| = 2.

Thus, c point is closest to yz-plane.

Hey there!

3(4y) + 3(-12) = 0

12y - 36 = 0

Add 36 to both sides

12y - 36 + 36 = 0 + 36

Cancel out: -36 + 36 because it give you 0

Keep: 0 + 36 because it help solve for the equation

New equation: 12y = 0 + 36

Simplify it

12y = 36

DIVIDE 12 to both sides

12y/12 = 36/12

Cancel out: 12/12 because that give you 1

Keep: 36/12 because it give you the y-value (also known as your overall result)

If four dice are rolled, what is the probability of obtaining two identical odd numbers and two identical even numbers?

Answers

Answer:

1/24 = 0.041666666...

Step-by-step explanation:

when rolling 4 dice, we have

6 × 6 × 6 × 6 = 6⁴ = 1296

different possible outcomes (each die has 6 possible outcomes).

so, the probability of any particular pattern is then

1/1296.

we need to find how many patterns there are to represent the desired result of 2 identical odd numbers combined with 2 identical even numbers.

there are on every die 3 out of 6 options for an odd number, and the other 3 out of 6 options for an even number.

when we roll 2 dice, the patterns for 2 identical odd numbers are

1 1

3 3

5 5

so, 3 out of the possible 36.

similar for 2 identical even numbers.

2 2

4 4

6 6

3 out of the possible 36.

so, combining this together for a roll of 4 dice, we get then

3 × 3 out of the possible 36 × 36

9 out of the possible 1296 patterns.

that means the probability (desired over total possible cases) for a specific combination of 2-and-2 dice is

9/1296 = 1/144 = 0.006944444...

but there are 4! / (2! × 2!) = 6 possibilities (pick 2 out of 4, where the sequence of the picked ones does not matter) to pick 2 dice out of 4 and to show the same pattern across the 4 dice, as e.g. for the basic pattern 1 1 2 2 we can have

1 1 2 2

1 2 1 2

1 2 2 1

2 1 2 1

2 1 1 2

2 2 1 1

all of the 9 patterns have these 6 combination possibilities.

so, we need to multiply the individual pattern probability by 6 for the total probability

1/144 × 6 = 6/144 = 1/24 = 0.041666666...
