The linear equation is y = 6x + 5

A statement that shows the equality of two mathematical expressions is known as an equation. The goal is typically to ascertain the values of the variables that keep the equation true, and it may have one or more variables. In that both sides must be equal for an equation to hold true, it might be likened to a balance scale.

To find the equation for the pricing formula, we can use the slope-intercept form of a linear equation:

y = mx + b

where y is the cost, x is the number of gallons, m is the slope (i.e., the rate of change of the cost per gallon), and b is the y-intercept (i.e., the cost when x = 0).

Using the given information, we can calculate the slope:

m = (35 - 11) / (5 - 1) = 24 / 4 = 6

The y-intercept can be found by plugging in one of the points:

11 = 6(1) + b

b = 5

Therefore, the linear equation for the pricing formula for Logan's Paint is:

y = 6x + 5

where y is the cost in dollars and x is the number of gallons.

The dimensions of the box that will minimize the cost of manufacturing it: base = 9.04 in and y = 3.01 in

And the minimum cost is 32.65 cents

Let us assume that x represents the base side of the box, and y represents the height of the box.

The volume of the box would be:

V = x²y

246 = x²y        ........(1)

The cost of the material for the base is 0.2 cents per square inch, and the cost of the material for the sides is 0.3 cents per square inch.

Since this box has 4 sides and 1 base, the total cost would be,

C = (0.2 × x² × 1) + (0.3 × 4 × xy)

C = 0.2x² + 1.2x(246x⁻²)              (from (1) y = 246x⁻²)

C = 0.2x² + 295.2 x⁻¹

Consider derivative with respect to x,

dC/dx = 0.4x - 295.2 x⁻²

Consider dC/dx = 0

So,  0.4x - 295.2 x⁻² = 0

0.4x³ =  295.2

x³ = 738

So, x = 9.04

So, the value of y would be:

y = 246 x⁻²

y = 246 × (9.04)⁻²

y = 3.01

So, the minimum cost would be:

C = (0.2 × 0.04² × 1) + (0.3 × 4 × 9.04 × 3.01)

C = 32.65

Therefore, the minimum cost is: 32.65 cents

using what we know about whole number division can be helpful when dividing with fractions. We can use the inverse operation of multiplication, simplify fractions, and use estimation to check our work and ensure that our division is accurate.

When dividing with fractions, one can use what they know about whole number division to check their work. This is because the rules of division remain the same for both whole numbers and fractions. One important rule is that division is the inverse operation of multiplication. In other words, when we divide, we are essentially finding how many times one number (the divisor) fits into another number (the dividend).

To check our work when dividing with fractions, we can use the same approach. We can multiply the quotient (the result of our division) by the divisor to see if we get back the dividend. If we do, then we know that our division was correct. For example, if we divide 3/4 by 1/2 and get a quotient of 3/2, we can check our work by multiplying 3/2 by 1/2.

Another important rule is that we can simplify fractions before dividing them to make the process easier. This means that we can divide both the numerator and the denominator by a common factor to get an equivalent fraction with smaller numbers. For example, if we want to divide 6/8 by 2/3, we can simplify 6/8 to 3/4 and 2/3 to 8/12. Then we can divide 3/4 by 8/12, which is much easier.

Finally, we can also use estimation to check our work when dividing with fractions. Estimation involves rounding the fractions to the nearest whole number or using benchmarks, such as 1/2 or 1, to get an approximate answer. This can help us quickly check if our quotient is reasonable or if we made an error in our division.

Answer:

The correct answer is:

x = 0°, 30°, 150°, 180°

This is because the sine function equals 0 at 0° and 180° and equals 1/2 at 30° and 150°.

Step-by-step explanation:

The frequency of a sound wave is the number of cycles it completes in a given amount of time. In this case, we can find the frequency of each sound wave by looking at the period of the functions.

The function y = 2sin2x has a period of π (since 2sin(2x) has a period of π/2, which is then compressed horizontally by a factor of 2). The function y = sinx has a period of 2π.

If the frequencies are the same, then the two functions must complete an equal number of cycles in the interval [0°, 360°), which is the same as the interval [0, 2π) in radians.

Let's first look at the function y = sin x. It completes one cycle in the interval [0, 2π), so we can say that it completes n cycles in the same interval, where n is an integer.

Now let's look at the function y = 2sin2x. It completes two cycles in the interval [0, π), so it completes four cycles in the interval [0, 2π). Therefore, we can say that it completes m cycles in the interval [0, 2π), where m is an integer.

For the frequencies to be the same, we need to find values of n and m such that:

n = m

Solving for n and m, we get:

n = m = 2

So both functions complete two cycles in the interval [0, 2π). We can find the times when this occurs by setting the angles in radians equal to multiples of 2π/2, or π:

2sin2x = sin x

2sin2x - sin x = 0

sin x (2sin x - 1) = 0

sin x = 0 or 2sin x - 1 = 0

sin x = 0 when x is an integer multiple of π.

2sin x - 1 = 0 when sin x = 1/2, which occurs when x = π/6 or x = 5π/6.

Therefore, the frequencies of the sound waves are the same at x = π/6, x = π/2, x = 5π/6, and x = 3π/2.

The correct answer is:

x = 0°, 30°, 150°, 180°

This is because the sine function equals 0 at 0° and 180° and equals 1/2 at 30° and 150°.

Topic: The significance of the Greek philosophical idea of "Logos" in contemporary scientific disciplines.

Greek philosophy's basic idea of "Logos" has had numerous interpretations throughout history. The word "logos" is most commonly used to refer to reasoned discourse and language. It is frequently linked to human conversation and reasoning as well as the cosmic or divine principle that creates and sustains the universe.

The significance of "Logos" can be observed in its impact on contemporary scientific disciplines, including, but not limited to, biology, psychology, and technology. For instance, the word "biology" is derived from the Greek terms "bios" (life) and "logos" (word or reason), illustrating the notion that the study of life necessitates both practical observation and logical analysis.

Parallel to this, the scientific discipline of psychology, which examines how the human mind and behaviour function, gets its name from the Greek words "psyche," which means "soul," and "logos," which means "reason." This illustrates the notion that both empirical research and theoretical analysis are necessary for the study of the mind and behaviour.

After answering the presented question, we can conclude that As a result, the equation of the straight line passing through (3,5) and having an x-intercept three times the y-intercept is: 5x - 9y = -42

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x Plus 3" equals the value "9." The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. The variable x is raised to the second power in the equation "x2 + 2x - 3 = 0." Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.

To find a straight line's equation, we must first establish its slope and y-intercept.

[tex](y - 5) = m(x - 3) (x - 3)\\b - 5 = -3m\\[/tex]

When we solve for b, we get:

[tex]b = -3m + 5\\5 - 5 = m(3 - 3) (3 - 3)\\0 - 5 = m(3b - 3) (3b - 3)\\-5 = 3bm - 3m\\[/tex]

When we simplify, we get:

[tex]m = 5/(9b) (9b)\\[/tex]

Substituting this expression for m in the equation for the y-intercept b results in:

[tex]b = -15/(9b) + 5\\9b^2 = -15b + 45b\\9b^2 - 30b = 0\\3b(3b - 10) = 0\\b = 10/3\\(y - 5) = m(x - 3) (x - 3)\\(y - 5) = 5x/(9*10) - 1/3\\9y - 45 = 5x - 3\\5x - 9y = -42\\[/tex]

As each side of the cube has a surface area of 24in².the total amount of wrapping paper needed is 64in².

Surface area is the total area of a three-dimensional object's surface, including the area of its faces and any curved surfaces.

To calculate the amount of wrapping paper needed for the cube, we can use the formula for the surface area of a cube:

SA = 6 x (side)²

In this case, the side of the cube is 2in,

so the SA = 6 x (2in)² = 24in²

To get the amount of wrapping paper needed, we would need to multiply this by 4, as each side of the cube has a surface area of 24in².

Therefore, the total amount of wrapping paper needed is

24in² x 4 = 96in²

To convert this to a square, we would need to divide it by 4, as each side of the square is equal in length.

Therefore, the total amount of wrapping paper needed is

96in² / 4

= 24in x 4

= 64in².

1/4 square centimeter is therefore equal to 1/2 square centimeter.

In math, what is a fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears inside the numerator and denominator of a complex fraction. The numerator of a proper fraction has a smaller denominator.

While "1/2-centimeter square" refers to a square having the side length of half a centimeter, the marking "1/2 square centimeter" typically refers to an area equal half a square centimeter. Even though these aren't the same object, we can still calculate the ratio of one to the other.

The area of such a square of side length 1/2 centimeter is:

(1/2 cm) x (1/2 cm) = 1/4 square centimeter

We may divide 1/4 by 1/2 to determine the percentage of 1/2 square centimeter that corresponds to 1/4 square centimeter:

(1/4 square cm) ÷ (1/2 square cm) = (1/4) x (2/1) = 1/2

The correct option is (a), i.e. The mean would increase.

What is mean?

Mean is a measure of central tendency that is commonly used in statistics and mathematics. The mean of a set of numbers is calculated by adding up all the numbers in the set and dividing the sum by the total number of values in the set.

The mean of the number of air conditioner units sold by the 10 sales representatives last year can be calculated by adding up all the sales and then dividing by the total number of representatives, which is 10:

Mean = (6 + 8 + 10 + 11 + 12 + 16 + 17 + 21 + 32 + 36) / 10

= 169 / 10

= 16.9

So the mean number of air conditioner units sold per representative is 15.9.

If the representative who sold the lowest number of units left the department and his sales are cancelled out, the new sum of sales will be:

6 + 8 + 10 + 11 + 12 + 16 + 17 + 21 + 32 + 36 - 6 = 163

This is because we subtract the sales of the representative who left (which is 6 units in this case). The new mean can then be calculated by dividing this sum by the new total number of representatives, which is 9:

New mean = 163 / 9

= 18.11

So the new mean number of air conditioner units sold per representative is 18.11, which is higher than the original mean of 16.9. This is because removing the lowest value (which is smaller than the mean) increases the overall average.

The number of rubber bands that Alana has to add to the ball to increase its diameter by 1 cm is 74.

Given that:

Alana is making a ball out of rubber bands.

The volume of the ball with 54 rubber bands is found as below:

Diameter of the ball = 3 cm

The radius of the ball is half of the diameter.

So, radius, r = 1.5 cm

So, the volume of the ball formed by 54 rubberbands is:

[tex]V=\frac{4}{3}\pi r^3[/tex]

Substitute r = 1.5.

[tex]V=\frac{4}{3} \pi (1.5)^3[/tex]

[tex]V=4.5\pi[/tex]

Now, the volume of the ball formed by 1 rubber band or the volume of the rubber band is:

[tex]V(r)=\frac{4.5\pi }{54}[/tex]

[tex]V(r)=\frac{\pi }{12}[/tex]

When the diameter increased by 1 cm, the new diameter is 4 cm and thus the radius is 2 cm.

So, the increase in volume is:

[tex]\frac{4}{3} \pi (2)^3-\frac{4}{3} \pi (\frac{3}{2} )^3=\frac{37\pi }{6}[/tex]

Now, divide this by the volume of one rubber band to get the number of rubber bands to be added.
