Which of the following rational functions is graphed below?
Mars2501 [29]

Answer:

Option B.

Step-by-step explanation:

We can see that we have an asymptote at x = 2

Remember that in a rational function, the asymptote is at the x-value such that the denominator is equal to zero.

So, the denominator is something like:

(x + a)

we have that the denominator is zero when x = 2

Then:

(2 + a) = 0

solving that for a, we get:

a = -2

Then the denominator of the rational function is:

(x - 2)

For the given options, the only one with this denominator is option B, then the correct option is B.

If a² = 7/36, then a is a) Rational b) irrational c) whole number d) integer
Dvinal [7]

Answer:

a = + or - sqrt(7)/6, which are irrational ( Answer Choice (b) ) for either case.

Step-by-step explanation:

a^2 = 7/36 implies that

a^2 - 7/36 = 0, by subtracting 7/36 from both sides of the equation, which implies that

(a - sqrt(7)/6)(a + sqrt(7)/6) = 0, by factoring, which implies that

a - sqrt(7)/6 = 0  or  a + sqrt(7)/6 = 0, by the zero product property of the real number system, which implies that

a = sqrt(7)/6 or a = - sqrt(7)/6, which are both irrational, since sqrt(7) is irrational and an irrational number divided by an integer (other than 0) is irrational.

Select the correct answer. The volume of one of the Great Lakes is 3. 5 × 103 cubic kilometers. If there are 6. 3 × 107 fish in
valentinak56 [21]

The average number of fish per cubic kilometer is 1. 8 \times 10^4.

The correct option is B.

Given

The volume of one of the Great Lakes is 3.5 × 103 cubic kilometers.

The number of fish in the lake = 6. 3 × 107.

<h3>What is the average value?</h3>

The average is the middle value of the given data set and is calculated by adding up all the numbers and dividing the result by the total quantity of figures added.

The average number of fish per cubic kilometer is given by;

\rm \text{The average number of fish per cubic kilometer}= \dfrac{Number \ of \ fish \ in \ lake}{Total \ volume \ of \ lake}

Substitute all the values in the formula;

\rm \text{The average number of fish per cubic kilometer}= \dfrac{Number \ of \ fish \ in \ lake}{Total \ volume \ of \ lake}\\\\ \text{The average number of fish per cubic kilometer}= \dfrac{6.3\times 10^7}{3.5\times 10^3}\\ \text{The average number of fish per cubic kilometer}= 1.8 \times 10^4

Hence, the average number of fish per cubic kilometer is 1. 8 \times 10^4.
