The range of the function y = 1/2 x + 2 is {0, 1, 2}, if the domain of the function is {-4, -2, 0}.

An expression, rule, or law in mathematics that specifies the relationship between an independent variable and a dependent variable.

The given function is,

y = 1/2 x + 2.

Also, the domain of the function is {-4, -2, 0}.

Since, the domain of the functions defines the values of x,

And range defines the value of y in function.

The value of y at x = -4

y = 1/2(-4) + 2 = -2 + 2 = 0

At x = -2,

y = 1/2(-2) + 2 = -1 + 2 = 1

At x= 0,

y = 1/2 (0) + 2 = 2

The values of y are 0, 1 and 2.

Hence, the range of the function is {0, 1, 2}.

A graph of the given piecewise-defined function is shown in the image below.

In Mathematics and Geometry, a piecewise-defined function simply refers to a type of function that is defined by two (2) or more mathematical expressions over a specific domain.

Generally speaking, the domain of any piecewise-defined function simply refers to the union of all of its sub-domains. By critically observing the graph of this piecewise-defined function, we can reasonably infer and logically deduce that it is constant over several intervals or domains such as x > 2 and x < -2.

In conclusion, this piecewise-defined function has a removable discontinuity.

In order to construct a Venn diagram for a survey, first enter the cardinality of the universal set to obtain subsequent cardinalities.

The universal set is the set of all possible outcomes, and the cardinality of a set is the number of elements in the set. Once you have the cardinality of the universal set, you can use it to calculate the cardinality of any other set in the survey.

For example, if the universal set has a cardinality of 100, and the survey asks people whether they like dogs or cats, you can calculate the number of people who like dogs by subtracting the number of people who like cats from the total number of people surveyed.

In order to construct a Venn diagram, you will need to draw two or more circles, each representing a set in the survey. The circles should be overlapping to represent the sets that have members in common.

Answer:

2.5

Step-by-step explanation:

Given expression:

\(6 \times \left(\dfrac{2}{3} \div 2\right)+0.5\)

Following the order of operations (PEDMAS), carry out the calculation inside the parentheses first.

When dividing a fraction by a whole number, first covert the whole number into a fraction:

\(\implies 6 \times \left(\dfrac{2}{3} \div \dfrac{2}{1}\right)+0.5\)

When dividing fractions, flip the second fraction (swap the numerator and denominator), then multiply:

\(\implies 6 \times \left(\dfrac{2}{3} \times \dfrac{1}{2}\right)+0.5\)

\(\implies 6 \times \left(\dfrac{2 \times 1}{3\times2}\right)+0.5\)

\(\implies 6 \times \left(\dfrac{2}{6}\right)+0.5\)

\(\implies 6 \times \dfrac{2}{6}+0.5\)

Now carry out the multiplication:

\(\implies \dfrac{6 \times2}{6}+0.5\)

\(\implies \dfrac{\diagup\!\!\!\!6 \times2}{\diagup\!\!\!\!6}+0.5\)

\(\implies 2+0.5\)

Finally carry out the addition:

\(\implies 2.5\)

2.5

6*(2/3)/2 + 0.5

6*1/3 + 0.5

2 + 0.5

=2.5

Solving a system of equations, we will see that there are 37 elves helping Santa, and 21 reindeer.

Let's define the variables:

We know that there are 58 of them, then we can write:

x + y = 58

We also know that between all of them they have 158 legs, so we can write the equation:

x*2 + y*4 = 158

Then the system of equations is:

x + y = 58

x*2 + y*4 = 158

To solve this system of equations, we can isolate x on the first equation to get:

x = 58 - y

Replacing that in the other equation we will get:

(58 - y)*2 + y*4 = 158

Now we can solve this equation for y.

(58 - y)*2 + y*4 = 158

116 - 2y + 4y = 158

116 + 2y = 158

2y = 158 - 116

2y = 42

y = 42/2

y = 21

Then the value of x is:

x = 58 - y

x = 58 - 21

x = 37

there are 37 elves.

The value of 3.5 divided by 85 will be 0.4118.

Division is one of the four basic arithmetic operations, or the process by which two numbers are added together to produce a new number. Multiplication, addition, and subtraction make up the remaining operations.

Division's opposite is multiplication. Dividend Divisor = Quotient + Remainder is a formula for calculating the division of two numbers.

The dividend in this situation refers to the number that is being divided. The divisor is the number that divides the number (dividend) into equal parts.

In this case, 3.5 ÷ 85 = 0.4118. This can be computed through the use of a calculator.

Answer:

p(c) = 8

Step-by-step explanation:

Given polynomial:

\(p(x)=x^4+7x^3+2x^2+20x+50\)

Remainder Theorem

When we divide a polynomial f(x) by (x − c) the remainder is f(c).

Therefore, if c = -7, then the divisor is:

\(\implies (x - (-7)) = (x + 7)\)

Perform Synthetic Division

Place "c" in the division box.

Write the coefficients of the dividend in descending order.

(Note: As no terms are missing, we do not need to use any zeros to fill in missing terms).

\(\begin{array}{c|ccccc}-7 & 1 & 7 & 2 & 20 & 50\\\cline{1-1}\end{array}\)

Bring the leading coefficient straight down:

\(\begin{array}{c|ccccc}-7 & 1 & 7 & 2 & 20 & 50\\\cline{1-1}&\downarrow &&&&\\\cline{2-6}&1\end{array}\)

Multiply the number you brought down with the number in the division box and put the result in the next column (under the 7):

\(\begin{array}{c|ccccc}-7 & 1 & 7 & 2 & 20 & 50\\\cline{1-1}&\downarrow &-7&&&\\\cline{2-6}&1\end{array}\)

Add the two numbers together and put the result in the bottom row:

\(\begin{array}{c|ccccc}-7 & 1 & 7 & 2 & 20 & 50\\\cline{1-1}&\downarrow &-7&&&\\\cline{2-6}&1&0\end{array}\)

Repeat:

\(\begin{array}{c|ccccc}-7 & 1 & 7 & 2 & 20 & 50\\\cline{1-1}&\downarrow &-7&0&&\\\cline{2-6}&1&0&2\end{array}\)

\(\begin{array}{c|ccccc}-7 & 1 & 7 & 2 & 20 & 50\\\cline{1-1}&\downarrow &-7&0&-14&\\\cline{2-6}&1&0&2&6\end{array}\)

\(\begin{array}{c|ccccc}-7 & 1 & 7 & 2 & 20 & 50\\\cline{1-1}&\downarrow &-7&0&-14&-42\\\cline{2-6}&1&0&2&6&8\end{array}\)

The bottom row (except the last number) gives the coefficients of the quotient. The degree of the quotient is one less than that of the dividend.

The last number in the bottom row is the remainder.

\(\textsf{Quotient}: \quad x^3+2x+6\)

\(\textsf{Remainder}: \quad 8\)

Therefore, as the remainder is p(c) then:

\(p(c)=8\)

Check by evaluating p(-7):

\(\begin{aligned}\implies p(-7)&=(-7)^4+7(-7)^3+2(-7)^2+20(-7)+50\\&=2401-2401+98-140+50\\&=0+98-140+50\\&=98-140+50\\&=-42+50\\&=8 \end{aligned}\)

Answer:

\(x = 3\)

Step-by-step explanation:

Given

\(y = -2x^2 + 12x +7\)

Required

The x coordinate of the vertex

Using the general form:

\(y = ax^2 +bx +c\)

The x coordinate is:

\(x = -\frac{b}{2a}\)

In \(y = -2x^2 + 12x +7\)

\(a = -2\)

\(b = 12\)

\(c = 7\)

So, we have:

\(x = -\frac{b}{2a}\)

\(x = -\frac{12}{2*-2}\)

\(x = -\frac{12}{-4}\)

\(x = \frac{12}{4}\)

\(x = 3\)

In this case, either method is straightforward, so the choice between substitution and elimination is a matter of personal preference.

The most convenient method for solving the system of equations depends on the particular equations and what makes the most sense for you. However, in this case, either method could be used.

Using substitution, you can solve for one variable in one of the equations and then substitute that expression into the other equation. This results in a single equation in one variable, which can then be solved. After finding one of the variables, you can then substitute it back into either equation to find the other variable.

Using elimination, you can add or subtract the equations to eliminate one of the variables. This also results in a single equation in one variable, which can then be solved. After finding one of the variables, you can then substitute it back into either equation to find the other.

It would take a total of 20 days to produce the batch of pens.

Let's calculate the work done by the 3 machines for the first 8 days:

Work done by 3 machines in 8 days = (3/12) * 8 = 2 days' worth of work

The remaining work that needs to be done by all 12 machines is:

Remaining work = 1 - (2/20) = 0.9

Now, we can use the work formula to find the total number of days needed to complete the remaining work with 12 machines:

Total work = 0.9

Work done by 12 machines in one day = 12/20 = 0.6

Total number of days needed = 0.9/0.6 = 1.5

Therefore, the total number of days needed to produce the batch of pens is:

8 (days with 3 machines) + 1.5 (days with 12 machines) = 9.5 days

However, we also need to add the 10.5 days it would take for all 12 machines to complete the batch from the beginning:
