Rationalize denominator, simplify, find equivalent choice.

To find the equivalent choice to the fraction (3 + √3) / (3 - √3), we need to rationalize the denominator. To do this, we multiply both the numerator and denominator by the conjugate of the denominator, which is (3 + √3). This will eliminate the square root in the denominator, allowing us to simplify the fraction.

The multiplication gives us:

(3 + √3) / (3 - √3) * (3 + √3) / (3 + √3)

= (9 + 6√3 + 3) / (9 - 3)

= (12 + 6√3)

Therefore, the equivalent choice is (C) 12 + 6√3.

To check our answer, we can simplify the expression further by factoring out 6:

12 + 6√3 = 6(2 + √3)

We can see that this is the same expression as the original fraction, but simplified and without a radical in the denominator.

The algebraic expression for the given phrase would be: c + 6, where c represents the unknown quantity (number of cars in the garage) and 6 represents the number of cars outside.

To translate the following phrase into an algebraic expression, we need to use the variable c to represent the unknown quantity. The phrase is "the total of the number of cars in the garage and the 6 cars outside."

So, the algebraic expression is: c + 6Where "c" represents the number of cars in the garage.

The expression c + 6 represents the total number of cars, which is the sum of the number of cars in the garage and the 6 cars outside.

Example: If there are 10 cars in the garage, then the total number of cars would be: c + 6= 10 + 6= 16.

So, there would be 16 cars in total.

The expression c + 6 would always give us the total number of cars, regardless of the value of "c."

Answer:

(X+5) (x+1)

Step-by-step explanation:

A removeable discontinuity is always found in the denominator of a rational function and is one that can be reduced away with an identical term in the numerator. It is still, however, a problem because it causes the denominator to equal 0 if filled in with the necessary value of x. In my function above, the terms (x + 5) in the numerator and denominator can cancel each other out, leaving a hole in your graph at -5 since x doesn't exist at -5, but the x + 1 doesn't have anything to cancel out with, so this will present as a vertical asymptote in your graph at x = -1, a nonremoveable discontinuity.

Step-by-step explanation:

The perimeter of ABC with vertices A(-4,4), B(2,-2), and C(-4,-2) is 20.848 units.

We are given the vertices:

A(-4,4), B(2,-2), and C(-4,-2).

We need to find the perimeter of ABC.

AB = √ ( 2 + 4)² + (-2 - 4)²

AB = √ 6² + 6²

AB = √72

AB = 6 √2 units

BC = √ (-4 - 2)² + ( -2 + 2)²

BC = √ 6²

BC = 6 units

AC = √ ( -4 + 4)² + (-2 - 4)²

AC = √ 6²

AC = 6 units.

Perimeter = AB + BC + AC

Perimeter = 6 √2 + 6 + 6 units

Perimeter = 12 + 6 √2 units.

Perimeter = 12 + 6(1.414) units

Perimeter = 12 + 8.848 units

Perimeter = 20.848 units

Therefore, the perimeter of ABC with vertices A(-4,4), B(2,-2), and C(-4,-2) is 20.848 units.

Next year population of this city will be 237886

Let the current population of the city is X

Population in a city is the measure of the total living people in that city. Increase in population signifies the addition of living people while decrease in population signifies the subtraction of living people.

Net decrease in the population rate per year is 1.7%

According to the question, Present population of the city is 242000

Therefore, X = 242000

Now as per the question, next year population will be 1.7% less than this year population

Therefore, next year population will be

X - 1.7% of X

Here X = 242000

Therefore,

= 242000 - 1.7% of 242000

= 242000 - 0.017(242000)

= 242000 - 4114

The type of sampling described in the scenario is known as systematic sampling.

Systematic sampling involves selecting elements from a population in a systematic and predetermined manner. In this case, the researcher is selecting every 20th name from the student directory to form her sample. This method of sampling is relatively simple to execute and can be less time-consuming compared to other methods such as random sampling. However, it is important to ensure that the selected interval does not coincide with any underlying patterns in the population that may bias the results.

Overall, systematic sampling can be a useful method for obtaining a representative sample from a large population, but it is important to consider the potential limitations and biases associated with this approach.

The probability of selecting a blue marble from the bag is 10/40 or 1/4. This is because there are 10 blue marbles out of a total of 40 marbles in the bag.

Probability is a measure of how likely an event is to occur as a fraction or percentage between 0 and 1, or 0% and 100%. It is used to describe the likelihood of an event happening, and can be used to make predictions and decisions about the future.

To calculate the probability, divide the number of blue marbles by the total number of marbles.

Therefore, the probability of selecting a blue marble from this bag is 10/40 or 1/4.

This means that out of every 4 marbles taken from the bag, one of them will be blue.

The probability of any event can be expressed as a fraction, decimal, or percentage. In this case, the probability of selecting a blue marble is 25%, or 0.25.

This means that there is a 25% chance that the marble taken from the bag will be blue.

In conclusion, the probability of selecting a blue marble from a bag containing 8 red, 10 blue, and 22 green marbles is 10/40 or 1/4, which is equivalent to 25% or 0.25.

Answer:

One number line increases by 1, and the other increases by 6

Step-by-step explanation:

Paulie's opportunity cost of producing a cup of ice cream is 4 T-shirts while Vinny's opportunity cost (C) of producing a t-shirt is 0.53

The table entries are given as:

          Ice Cream (cups) T-shirts (quantity)

Paulie 5.00                          20.00

Vinny 8.00                              15.00

Paulie's opportunity cost of producing a cup of ice cream is calculated by dividing the number of T-shirts by the cups of ice cream.

So, we have:

\(C = \frac{20.00}{5.00}\)

\(C =4.00\)

Similarly, Vinny's opportunity cost (C) of producing a t-shirt is calculated by dividing the cups of ice cream by the number of T-shirts

So, we have:

\(C = \frac{8.00}{15.00}\)

\(C = 0.53\)

Hence, Vinny's opportunity cost (C) of producing a t-shirt is 0.53

An equation with one variable that has the usual form Ax + B = 0 is a linear equation. A coefficient, B is constant, and x is a variable in this situation. An equation with two variables that has the usual form Ax + By = C is a linear equation. Both a B are factors, C is a standard, and the variables in this solution are x and y. Linear equations are defined as equations with the maximum degree of 1. A linear equation cannot have a variable with an exponent greater than 1, according to this rule.
