The value of the functions at 9m is

Generally, In mathematics, a function is a rule that maps one set of values (the domain) to another set of values (the range). The values in the range are determined by applying the function to the values in the domain.

Functions can take many forms and be expressed in different ways, including:

Linear functions: a function that produces a straight line when graphed. It has the form f(x) = mx + b, where m is the slope of the line and b is the y-intercept.

Quadratic functions: a function that produces a parabola when graphed. It has the form f(x) = ax^2 + bx + c, where a, b, and c are constants.

Therefore, this function

Thus, the required rest stops are approximately 4.09 miles apart on the new map.

The scale factor is defined as the ratio of the modified change in length to the original length.

Here,
The total length of the highway in miles can be found by using the scale of the original map. Since 2 inches on the map represent 33 miles in reality, 6 inches on the map represent:

= 6 inches × (33 miles/2 inches) = 99 miles

Since there are 11 equally spaced rest stops along the highway,

= (99 miles)/(11 intervals) = 9 miles per interval

To create the new map with a scale of 1 inch = 30 miles, we need to use a scale factor of (1/2) × (30/33) = 15/33.

Therefore, the distance between each rest stop on the new map can be found by multiplying the distance between rest stops on the old map by the scale factor,

= (9 miles per interval) × (15/33) = 4.09 miles per interval

So, the required rest stops are approximately 4.09 miles apart on the new map.

The two points that would lie on the graph of function g are (-2,-12) and (1,30). The solution has been obtained by using functions.

What is a function?

An association between a number of inputs and a single output for each input is known as a function. A function is often written as f(x), where x stands for the input. A function is typically expressed as y = f(x).

We are given that f(x) passes through the points (-2,-4) and (1,10).

So, it means that

For x = -2,  f(-2) = -4

Similarly,

For x = 1, f(1) = 10

We are given g(x) = 3f(x)

So, on substituting the obtained values of f(x) in the g(x) function, we get

For x = -2,

⇒g(-2) = 3f(-2)

⇒g(-2) = 3(-4)

⇒g(-2) = -12

Similarly,

For x = 1,  

⇒g(1) = 3f(1)

⇒g(1) = 3(10)

⇒g(1) = 30

Hence, the two points that would lie on the graph are (-2,-12) and (1,30).

The correct relationship of the three principles is: The well-ordering principle for the integers is equivalent to strong mathematical induction, and neither is equivalent to weak mathematical induction.

The well-ordering principle for the integers states that every non-empty set of non-negative integers has a least element. Strong mathematical induction is a proof technique that involves proving that a statement is true for a base case, and then assuming that it is true for all cases up to a certain value, and then proving that it must also be true for the next case.

This requires assuming the truth of all cases up to a certain value, which is where the well-ordering principle comes in. Weak mathematical induction is a proof technique that involves proving that a statement is true for a base case, and then assuming that it is true for a particular case, and then proving that it must also be true for the next case.

Weak mathematical induction does not require assuming the truth of all cases up to a certain value, and is therefore weaker than strong mathematical induction.

Answer: 2.25 per gallon

Step-by-step explanation:

The expression [tex]m^{7} * n^{4}[/tex] divided by [tex]m^{4} * n^{3}[/tex] simplifies to [tex]m^{3} * n[/tex], meaning m raised to the power of 3 times n. This is found by subtracting the exponents in the denominator from the exponents in the numerator.

To simplify the expression [tex]\frac{m^{7} * n^{4}}{m^{4} * n^{3}}[/tex] , we need to divide the exponents of m and n. To do this, we subtract the exponents of m and n in the denominator from the exponents of m and n in the numerator.

Starting with m, we have:

[tex]\frac{m^{7}}{m^{4}}[/tex] = [tex]m^{(7-4)}[/tex] = [tex]m^{3}[/tex]

This means that we divided the exponent of m in the numerator (7) by the exponent of m in the denominator (4), and the result is m raised to the power of 3.

Next, we do the same thing with n:

[tex]\frac{n^{4} }{n^{3} }[/tex] = [tex]n^{(4-3)}[/tex] = [tex]n^{1}[/tex] = n

This means that we divided the exponent of n in the numerator (4) by the exponent of n in the denominator (3), and the result is n raised to the power of 1, which is just n.

Finally, we can combine the results:

[tex]m^{3}*n[/tex] = [tex]m^{3}*n[/tex]

So, the simplified form of the expression [tex]\frac {m^{7 }* n^{4}} { m^{4} * n^{3}}[/tex] is [tex]m^{3}*n[/tex].

The options that represent an amount and price of gas that Pedro purchased are 19 gallons of gas for $52.25, 16 gallons of gas for $44. So options C and D are correct.

To calculate the amount of gas and the total price that Pedro purchased, we need to use the formula:

Price = Cost per gallon * Number of gallons

Dividing the total price by the cost per gallon will give us the number of gallons purchased. We can then compare this with the given options to see which one(s) match.

Using the given cost per gallon of $2.75, we can check each option:

a) 13.75 gallons of gas for $41.25

Price = $2.75/gallon * 13.75 gallons = $37.81

This option does not match the total price of $41.25, so it is not correct.

b) 22 gallons of gas for $71.5

Price = $2.75/gallon * 22 gallons = $60.50

This option does not match the total price of $71.5, so it is not correct.

c) 19 gallons of gas for $52.25

Price = $2.75/gallon * 19 gallons = $52.25

This option matches the total price of $52.25, so it is correct.

d) 16 gallons of gas for $44

Price = $2.75/gallon * 16 gallons = $44

This option matches the total price of $44, so it is correct.

52 students passed only one subject

Let's use the following variables to represent the number of students who passed each subject:

P(Ga): the number of students who passed Ga

P(Fante): the number of students who passed Fante

From the problem statement, we know that:

P(Ga) = P(Fante) + 6, since the number of students who passed Ga is 6 more than the number who passed Fante

P(Ga ∩ Fante) = 8, since 8 students passed both subjects

P(Ga ∪ Fante) = 60, since every student passed at least one subject

We want to find the number of students who passed only one subject, which is equal to the total number of students who passed Ga minus the number of students who passed both subjects, plus the number of students who passed Fante but not Ga. In symbols:

P(Ga) - P(Ga ∩ Fante) + (P(Fante) - P(Ga ∩ Fante))

Substituting the values we know:

(P(Fante) + 6) - 8 + (P(Fante) - 8)

Simplifying:

2P(Fante) - 10

We also know that P(Ga) + P(Fante) - P(Ga ∩ Fante) = P(Ga ∪ Fante) = 60.

Substituting the values we know:

P(Ga) + P(Fante) - 8 = 60

P(Ga) + P(Fante) = 68

Substituting P(Ga) = P(Fante) + 6:

2P(Fante) + 6 = 68

2P(Fante) = 62

P(Fante) = 31

Therefore, the number of students who passed only one subject is:

2P(Fante) - 10 = 2(31) - 10 = 52

Therefore, 52 students passed only one subject.

Step-by-step explanation:

A rule for the nth term of the sequence for which a = 30 and r= 1/2 the 5th term of the sequence is 1.875.

What is the geometric sequence?

A geometric sequence is often referred to as geometric progression or geometric series is defined as a sequential pattern of non-zero numbers in which the following number's value is a multiplication from the preceding number by another constant non-zero number.

The rule for the nth term of a geometric sequence is given by the formula:

aₙ  = a * r⁽ⁿ⁻¹⁾

where "a" is the first term in the sequence, "r" is the common ratio, and "n" is the position of the term in the sequence.

In this case, we have "a" = 30 and "r" = 1/2. Substituting these values into the formula, we get:

aₙ = 30 x (1/2)⁽ⁿ⁻¹⁾

This is the rule for the nth term of the sequence with the first term 30 and common ratio 1/2.

To find the nth term of the sequence, we simply plug in the value of "n" into the formula. For example, the 5th term of the sequence would be:

a₅ = 30 * (1/2)⁽⁵⁻¹⁾ = 30 * (1/2)⁴ = 30 * 1/16 = 1.875

Therefore, the 5th term of the sequence is 1.875.
