A. packaging costs

Step-by-step explanation:

Packaging costs woupd change based on how many products are being shipped. The other payments are fixed because they are the same amount paid regularly. Packaging would be considered a variable cost.

Internet access fee is not an example of a fixed cost.

The fixed cost definition states that businesses incur a cost that does not change positively or negatively with the number of goods sold or services given.

A fixed cost is a cost that remains constant regardless of production or sales volume.

Examples of fixed costs include monthly rent, packaging costs, and weekly fixed electricity costs.

Internet access fee is not an example of a fixed cost since it fluctuates based on usage.

The cost of internet access fee will increase or decrease depending on the amount of data used or the duration of usage.

Hence, Internet access fee is not an example of a fixed cost.

Answer:

1170

Step-by-step explanation:

The bakery made 3 batches of cookies and a total of 180 cookies.

To determine the number of batches of cookies the bakery made, we divide the total amount of flour used by the amount of flour used in each batch. The bakery used 5.25 cups of flour in total, and each batch requires 1.75 cups of flour. Therefore, the number of batches made is:

[tex]\[ \text{Number of batches} = \frac{\text{Total flour used}}{\text{Flour per batch}} = \frac{5.25}{1.75} \][/tex]

[tex]\[ \text{Number of batches} = 3 \][/tex]

Since there are 5 dozen cookies in each batch, we multiply the number of batches by the number of cookies per batch to find the total number of cookies made:

[tex]\[ \text{Total number of cookies} = \text{Number of batches} \times \text{Cookies per batch} \][/tex]

[tex]\[ \text{Total number of cookies} = 3 \times (5 \times 12) \][/tex]

[tex]\[ \text{Total number of cookies} = 3 \times 60 \][/tex]

[tex]\[ \text{Total number of cookies} = 180 \][/tex]

Thus, the bakery made 3 batches of cookies, resulting in a total of 180 cookies."

Answer:

a. 10x + 2y = 23

b. 4x - y + 3 = 0

c. y + 8 = 0

d. 2x - y + 4 = 0

Step-by-step explanation:

a.

Slope of the line 'm' is [tex]\frac{36.5-1.5}{-5-2}[/tex] = [tex]\frac{35}{-7}[/tex] = -5

Equation of the line with slope m and passing through the point (x₁,y₁) is y-y₁ = m·(x-x₁)

⇒y-1.5 = -5·(x-2)

⇒y = -5x + 10 + 1.5

⇒5x + y = 11.5 (or) 10x + 2y = 23

b.

Slope of the line 'm' = 4

Equation of the line with slope m and passing through the point (x₁,y₁) is y-y₁ = m·(x-x₁)

⇒y-15 = 4·(x-3)

⇒y = 4x -12 + 15

⇒4x - y + 3 = 0

c.

Line is parallel to y = 1

Equations of parallel lines only differ by constant. So the required line equation has the form y = c where c is any real number.

But, it is given that the line passes through the point (3,-8)

⇒c=-8

⇒y = -8 (or) y + 8 = 0

d.

Equation of a line with slope 'm' and y-intercept of (0,c) is of the form y = mx + c

⇒y = 2x + 4

⇒2x - y + 4 = 0

Answer:

(1, - 2 )

Step-by-step explanation:

Given the 2 equations

y = - 4x + 2 → (1)

y = 6x - 8 → (2)

Substitute y = 6x - 8 into (1)

6x - 8 = - 4x + 2 ( add 4x to both sides )

10x - 8 = 2 ( add 8 to both sides )

10x = 10 ( divide both sides by 10 )

x = 1

Substitute x = 1 into (2) for corresponding value of y

y = 6(1) - 8 = 6 - 8 = - 2

Solution is (1, - 2 )

Answer:

Range = {-2, 1, 4, 13}

Step-by-step explanation:

Domain is the set of x-values that are allowed for the function. The values for which the function is defined.

Range is the set of y-values that are allowed for the fucntion. The values for which the function is defined.

Since domain is given as:

Domain = {-1, 0, 1, 4}

We have to plug in each of the 4 values and find the corresponding 4 values for the range. Lets do this below:

y = 3x + 1

y = 3(-1) + 1

y = -2

y = 3x + 1

y = 3(0) + 1

y = 1

y = 3x + 1

y = 3(1) + 1

y = 4

y = 3x + 1

y = 3(4) + 1

y = 13

So, the range would be:

Range = {-2, 1, 4, 13}

https://brainly.com/question/21620502

#SPJ12

Final answer:

To create equivalent systems of equations, one can use scaling to multiply an equation by a non-zero constant, substitution to replace variables with equivalent expressions, or elimination through addition or subtraction to reduce the number of variables.

Explanation:

When dealing with a system of equations, there are several methods to create equivalent systems, which effectively means rewriting the equations without changing the solution set. One common approach to achieve this is by using the following techniques:

Scaling: Multiplying an entire equation by a non-zero constant. This changes the coefficients but not the solutions.

Substitution: Replacing one variable with an equivalent expression derived from another equation in the system.

Elimination (Addition or Subtraction): Adding or subtracting equations from each other to eliminate one of the variables, effectively reducing the number of variables to solve for.

These methods allow us to simplify complex systems or prepare them for other solving techniques, such as matrix inversion or graphical representation.

The inequality which shows the number of weeks, w, you need to save to be able to go on a trip is 25w + 200 ≥ 535.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Total amount needed to go for a trip to California = $535

Already saved amount = $200

You decide to save an additional $25 per week.

Let w be the number of weeks needed to save $25 to get the amount needed to go for trip.

These saved amounts must be at least $535 to go for trip.

The amount saved after w weeks is 25w

Total saved amount = 200 + 25w

This saved amount must be ≥ 535.

So the inequality is 200 + 25w ≥ 535.

Hence the inequality which represents the amount need to save to go for trip is  200 + 25w ≥ 535.

Step-by-step explanation:

The returns are 15% of 1,300,000.

15% of 1,300,000 = 15% * 1,300,000 = 0.15 * 1,300,000 = 195,000

In 1 month, 195,000 smartphones were returned.

In 6 months, 6 times as many smartphones were returned.

6 * 195,000 = 1,170,000

Answer: 1,170,000

Answer:

1,170,000 Smartphones were returned over a 6-month period.

Step-by-step explanation:

Ok, so to start off, 15% of 1,300,000 is 195,000. Now if everything remains the same over the next 5 months, you just need to multiply the 195,000 by 6 to get the 6 month return rate. This results in the number of 1,170,000 Smartphones Returned over a 6-month period.

The value of a and b in given expression must be [tex]\frac{2}{5} \text { and } \frac{3}{5}[/tex] respectively so that given equality becomes identity.

Need to find the value of a and b in following expression so that following equality will become identity.

[tex]\frac{(x-1)}{(x+1)(x-4)}=\frac{a}{(x+1)}+\frac{b}{(x-4)}[/tex]   ------- eqn 1

Lets Simplify Right hand Side first,

[tex]\frac{a}{(x+1)}+\frac{b}{(x-4)}=\frac{a(x-4)+b(x+1)}{(x+1)(x-4)}[/tex]

[tex]\begin{array}{l}{=\frac{a x-4 a+b x+b}{(x+1)(x-4)}} \\\\ {=\frac{a x+b x-4 a+b}{(x+1)(x-4)}} \\\\ {=\frac{(a+b) x-4 a+b}{(x+1)(x-4)}}\end{array}[/tex]

[tex]=>\frac{a}{(x+1)}+\frac{b}{(x-4)}=\frac{(a+b) x-4 a+b}{(x+1)(x-4)}[/tex]

[tex]\text {On substituting } \frac{a}{(x+1)}+\frac{b}{(x-4)}=\frac{(a+b) x-4 a+b}{(x+1)(x-4)} \text { in equation } 1 \text { we get }[/tex]

[tex]\frac{(x-1)}{(x+1)(x-4)}=\frac{(a+b) x-4 a+b}{(x+1)(x-4)}[/tex]

On multiplying both sides by (x+1)(x-4) we get

[tex]\frac{(x-1)}{(x+1)(x-4)} \times(x+1)(x-4)=\frac{(a+b) x-4 a+b}{(x+1)(x-4)} \times(x+1)(x-4)[/tex]

[tex]\Rightarrow x-1=(a+b) x-(4 a-b)[/tex]

On comparing coefficient of x and constant term separately, we get

a + b = 1 and 4a - b = 1

On adding the two equations we get

a + b + 4a - b = 1 + 1

=> 5a = 2

=> [tex]a = \frac{2}{5}[/tex]

[tex]\text {Substituting } \mathrm{a}=\frac{2}{5} \text { in equation } a+b=1, \text { we get }[/tex]

[tex]\begin{array}{l}{\frac{2}{5}+b=1} \\\\ {\Rightarrow b=1-\frac{2}{5}=\frac{3}{5}}\end{array}[/tex]

So the value of a and b in given expression must be [tex]\frac{2}{5} \text { and } \frac{3}{5}[/tex] so that given equality becomes identity.

In a function, each "x" can only have one "y" number. A relation can still be a function if a y-value has more than one x-value.

Answer:

11. a)

The relationship represented by the graph is a function because it passes the vertical line test (VLT). Any vertical line you pass through the graph, it only "hits" one spot on the graph. For a relation to be a function, each x-value can only have one y-value. This means no hour can have two different amounts of bacteria.

b)

If there were the same number of bacteria for two consecutive hours, the graph would still represent a function. In this case, two values for "y" will have more than one value for "x". Although, each x-value still only has one y-value, so it's still a function.

Answer:

[tex]p (x) = x^{3} - 21x^{2}+ 147x - 343[/tex]

is the required polynomial with degree 3 and p ( 7 ) = 0

Step-by-step explanation:

Given:

p ( 7 ) = 0

To Find:

p ( x ) = ?

Solution:

Given p ( 7 ) = 0 that means substituting 7 in the polynomial function will get the value of the polynomial as 0.

Therefore zero's of the polynomial is seven i.e 7

Degree : Highest raise to power in the polynomial is the degree of the polynomial

We have the identity,

[tex](a -b)^{3} = a^{3}-3a^{2}b +3ab^{2} - b^{3}[/tex]

Take a = x

        b = 7

Substitute in the identity we get

[tex](x -7)^{3} = x^{3}-3x^{2}(7) +3x(7)^{2} - 7^{3}\\(x -7)^{3} = x^{3}-21x^{2} +147x - 343[/tex]

Which is the required Polynomial function in degree 3 and if we substitute 7 in the polynomial function will get the value of the polynomial function zero.

p ( 7 ) = 7³ - 21×7² + 147×7 - 7³

p ( 7 ) = 0

[tex]p (x) = x^{3} - 21x^{2}+ 147x - 343[/tex]

A polynomial function with degree 3 and P(7)=0 can be written as p(x) = a(x - 7)(x - r2)(x - r3), where r2 and r3 can be any real number and a is any non-zero real number.

The student has asked for a polynomial function with a degree of 3 such that P(7) equals 0. By definition, a polynomial function of degree n with given roots can be written as:

p(x) = a(x - r1)(x - r2)... (x - rn)

Since we have been given that P(7)=0 , we can choose 7 as one root, but the other roots can be chosen arbitrarily. So, we can create a polynomial function like below:

p(x) = a(x - 7)(x - r2)(x - r3)

Where r2 and r3 can be any real number and a is any non-zero real number. For example, if we choose r2=1, r3=2 and a=1. The function would be:

p(x) = 1*(x - 7)(x - 1)(x - 2) = ([tex]x^3 - 10x^2[/tex] + 29x - 14)
