Domain of function is in Set Builder Notation is, {x | x ≥ 7 }.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

⇒ f (x) = √(x-7) / (x³ + 1)

Now, We can find the domain of function as;

⇒ f (x) ≥ 0

⇒ √(x-7) / x³ + 1 ≥ 0

⇒ √ (x - 7) ≥ 0

⇒ x - 7 ≥ 0

⇒ x ≥ 7

Thus, Domain of function is in Set Builder Notation is, {x | x ≥ 7 }.

Answer:Not to simplify

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

9/10 is already in its simplest form. It cannot be further simplified as it is a fraction with two prime numbers in its numerator and denominator.

It is important to note that the probability of an exact match at all 16 loci is very low, as even small differences in the number of repeats at each locus can result in different genotypes. This makes it unlikely to find two individuals with an exact match at all loci.

The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms. The probability is a measure of the possibility that an event will occur. It assesses the event's certainty. P(E) = Number of Favourable Outcomes/Number of Total Outcomes is the probability formula.

Here,

To calculate the probability of an identical match at all 16 STR loci, you would need to determine the frequency of each unique genotype at each locus, and then multiply the frequencies of each unique genotype to obtain the probability of all 16 loci having the same genotype in two individuals.

This probability would be based on the genetic makeup of the population of elephants that the individuals are drawn from, and the specific alleles present at each locus in each individual.

A limit describes a function's value as it gets closer to a certain value as its inputs increase. All calculus is based on the concept of a limit.

There are one-sided limits (left- and right-hand limits), infinite limits, and limitations at infinity in addition to regular, two-sided limits.

Let's look at an example to better grasp what limits are. Beginning with the function f (x) = x + 2 f(x) = x + 2 f(x) = x + 2f, left parenthesis, x, right parenthesis, equals, x, plus, 2. The value f approaches as we move closer and closer to x = 3 x=3 x=3, which is the limit of f at x = 3 x=3 x=3.

The values of the two limits are lim x->33- g(x) = -15 and lim x->33+ g(x) = -6.

Option (B) is correct.

What is a limit in calculus?

The limits in mathematics describe the behavior of a function as the input approaches a certain value. The symbols for limits are "lim" followed by the variable and the value that the variable is approaching, with an arrow indicating the direction of the approach.

For the given function g(x), we have the following limits:

lim x->33- g(x) = -15.1

This means that as x approaches 33 from below, the value of g(x) approaches -15.1. We can see this from the values in the table, as x gets closer to 33 from below, g(x) gets closer to -15.1.

lim x->33+ g(x) = -6.1

This means that as x approaches 33 from above, the value of g(x) approaches -6.1. We can see this from the values in the table, as x gets closer to 33 from above, g(x) gets closer to -6.1.

So, the values of the two limits are lim x->33- g(x) = -15.1 and lim x->33+ g(x) = -6.1.

Hence, The values of the two limits are lim x->33- g(x) = -15 and lim x->33+ g(x) = -6.

f(1/7) = 3 3/4 in simplest form.

Step-by-step explanation:

To find the value of f(1/7), we can substitute 1/7 for x in the function:

f(1/7) = -7/4 * 1/7 + 4

f(1/7) = -7/4 * 1/7 + 4

f(1/7) = -7/28 + 4

f(1/7) = 4 - 7/28

f(1/7) = 4 - 1/4

f(1/7) = 3 3/4

So f(1/7) = 3 3/4 in simplest form.

Applying the secant-secant theorem, the value of x is: 12.

The secant-secant theorem states that if you draw two lines from a point outside a circle that intersect the circle at two different points, then the product of the length of one line segment and the length of the portion of the line outside the circle is equal to the product of the length of the other line segment and the length of its portion outside the circle.

Based on the secant-secant theorem, we have:

EF * ES = ED * EC

Substitute the values:

8(8 + 10) = 9(2x - 17 + 9)

Solve for x:

Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".

To calculate the 10% down payment required by the bank, you can use the following formula:

Down payment = 2700 x 10%

                          = $270

To calculate the loan amount, you can subtract the down payment from the total cost of the moped:

Loan amount = 2700 - 270

                      = $2430

To calculate the monthly loan payment, you need to know the interest rate, the loan amount, and the number of months in the loan term. You can use the following formula to calculate the monthly payment:

Monthly payment = (Loan amount x Interest rate) / (1 - (1 + Interest rate)^(-Number of months in loan term))

In this case:

Monthly payment = ($2430 x 8%) / (1 - (1 + 8%)⁻⁶)

Monthly payment = $44.38

The breakdown of each of the 6 payments would be $44.38 per month.

If Pete sells 50 pizzas, he will make a profit of $75. The equation can be used to determine the profit is y = 5.50x - 200.

Pete's Pizzas charges $5.50 per pizza and has spent $200 in supplies to start his business.

We can use the following equation to determine the total profit he will make after he sells x amount of pizzas:

y = 5.50x - 200

where y is the total profit, 5.50 is the revenue per pizza, x is the number of pizzas sold, and -200 is the fixed cost for the supplies.

For example, if Pete sells 50 pizzas, we can plug in the values into the equation:

y = 5.50 * 50 - 200

y = 275 - 200

y = 75

The system of linear equations shown in the graph has no solution.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Both linear equations with one variable and those with two variables exist.

Given the coordinates of two lines,

line 1: line passes from (0, 3) and (3, 2)

and slope of the line is given by,

m = (y₂ - y₁)/(x₂ - x₁)

m = (2 - 3)/(3 - 0)

m = -1/3

Line 2: line passes from (0, -2) and (3, -3)

slope =  (y₂ - y₁)/(x₂ - x₁)

m = (-3 - (-2))/(3 - 0)

m = -1/3

since both, the lines have the same slope so both lines will be parallel,

If two lines are parallel, they will never intersect and so there is no solution to the given system of equations.

A rhombus is a quadrilateral with four equal-length sides in planar Euclidean geometry. The term equilateral quadrilateral refers to the fact that all of its sides are the same length.

Note that the above-described Rhombus is described accordingly. Since the diagonals are perpendicular to each other and bisect one another each at an inner angle that is 90° each, then we can say that;

The correct answer is option c. There are no real-valued functions that have a domain of all real numbers and a range of all integers.

A function maps an input (or domain) to a unique output (or range). In order for a function to have a domain of all real numbers, it must take any real number as an input and provide a unique output. However, for a function to have a range of all integers, it must be the case that every output is an integer.

Since the real numbers are not countable and the integers are countable, there can be no function that maps every real number to a unique integer. In other words, there is no one-to-one correspondence between the real numbers and the integers, which means that it is not possible to find a function that maps every real number to an integer.

Answer:

Jamie has $12.50 of her allowance left if the books cost $2.50 each.

Step-by-step explanation:

To calculate this, first calculate the total cost of the books:

5 books x $2.50/book = $12.50.

Then subtract the cost of the books from the amount Jamie has saved:

$38 - $12.50 = $25.50.

Finally, subtract the cost of the books from the amount Jamie has saved to get the amount she has left:

$25.50 - $12.50 = $12.50.

Answer:

$25.50

Step-by-step explanation:

We know Jamie bought 5 books, each worth $2.50, d. We need to know the cost of all five, so we’ll go ahead and multiply 5 times $2.50 to get $12.50.

Since we know how much the books cost, all we have to do now is subtract the amount she spent from her allowance. $38.00 - $12.50 is 25.50, the amount of money Jamie has left.
