The equivalenet expression is 54\(n^{-11}\)

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression.

The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.

To simplify the given expression, we need to apply the power of a power rule, which states that to raise a power to another power, we need to multiply the exponents.

Starting with:

(\(6n^-5\))(\(3n^-3\))²

We can simplify as follows:

(\(6n^-5\))(\(9n^-6\))

Now, we can use the product of powers rule, which states that when multiplying two powers with the same base, we add their exponents.

Therefore:

6 x 9 = 54

\(n^-5 * n^-6 = n^-11\)

So the simplified expression is:

\(54n^-11\)

Therefore, the expression \((6n^-5)(3n^-3)^2\) is equivalent to \(54n^-11.\)

The expression that is equal to (6n-5)(3n-3) option D, 54n11.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.

We can use the distributive property of multiplication to expand the expression (6n - 5)(3n - 3) as follows:

(6n - 5)(3n - 3) = 6n(3n) - 6n(3) - 5(3n) + 5(3)

                 = 18n² - 18n - 15n + 15

                 = 18n² - 33n + 15

Therefore, the expression that is equivalent to (6n - 5)(3n - 3) is 18n² - 33n + 15, which is option D.

So, the answer is option D, 54n11.

Answer:

B. 1

Step-by-step explanation:

I calculated it logically

Answer:

a = 4

Step-by-step explanation:

first, you are supposed to subtract both sides by 6 so you will get:

                                          6 - 4a = -10

                                         -6            -6

                                          -4a = -16

Then, you divide both sides by -4 to cancel out the -4 before the "a"

                                          -4a = -16

                                          -4      -4

Last, you will get a = 4 and that is your answer because when you divide a negative number by another negative number, you will get a positive number.

Answer:

  (-1, -3)

Step-by-step explanation:

Of the ordered pairs given in the table, the one with the smallest y-value is (-2, -8). That is not among the answer choices, so you must select the answer choice that has the smallest y-value that is -8 or greater.

  (-1, -3) is the closest to the local minimum

Of the ordered pairs given in the table, the one with the smallest y-value is (-2, -8). The smallest y-value that is -8 or greater.  (-1, -3) is the closest to the local minimum.

In mathematics, a function is a statement, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Y and x are coupled in such a way that there is a distinct value of y for each value of x, and this relationship is frequently represented as y = f(x), or "f of x." In other words, the same x cannot include multiple values for f(x). A function connects an element x with an element f(x) within another set, which utilises the language underlying set theory. Of the ordered pairs given in the table, the one with the smallest y-value is (-2, -8). The smallest y-value that is -8 or greater.  (-1, -3) is the closest to the local minimum.

Therefore,  (-1, -3) is the closest to the local minimum.

Step-by-step explanation:

The length of CD is 12.686

From the figure, we have,

AB= 6 cm, AC = 12 cm

In Δ ABC,

Using Pythagoras Theorem,

AC² = AB + BC²

12² = 6² + CB²

CB² = 12² - 6²

CB² = 144 - 36

CB² = 108

∴ CB = √ 108 cm.

In Δ BCD,

sin 55°=  perpendicular / hypotenuse

sin 55° = CB / CD

0.81915 = √108 / CD

CD = 10.392 / 0.81915

CD = 12.686

Multiplication:

In mathematics, multiplying the numbers is used to find the product of two or more numbers. We carry out one of the basic mathematical operations on a regular basis. The main application that is obvious is using multiplication tables. Mathematicians use the multiplication of two integers to express the repeated addition of one number to another. These numbers can be natural numbers, fractions, integers, whole numbers, etc. M is either added to itself 'n' times or subtracted from itself when m is multiplied by n.

Given that:

To find the revenue received when p equals 91 dollars, substitute 91 for p into the formula of R(p).

4186 dollars received from selling the shoes at a cost of 91 dollars.

Answer:

x = 64 weeks

Step-by-step explanation:

Based on the quantity of water in the tanks and the leakage rate, the two tanks will be equal after 64 weeks.

The first tank has 256 gallons and is leaking at 3 gallons per week. Assuming the number of weeks is x, the expression is:

= Water in tank - (Gallons leaking per week x No. of weeks)

= 256 - (3 × x)

= 256 - 3x

The second tank:

= 384 - 5x

To find the number of weeks they would be equal, equate both tanks:

384 - 5x = 256 - 3x

384 - 256 = -3x + 5x

128 = 2x

x = 128 / 2

Based on the cross-price elasticity of Demand, we can conclude that good X and good Y are substitutes.

Let's calculate the cross-price elasticity of demand using the given information:

a. Find the percentage change in quantity demanded of good Y:

Percentage Change in Quantity Demanded of Good Y = (New Quantity Demanded - Initial Quantity Demanded) / Initial Quantity Demanded * 100

Percentage Change in Quantity Demanded of Good Y = (6250 - 5000) / 5000 * 100 = 25%

b. Find the percentage change in the price of good X:

Percentage Change in Price of Good X = (New Price - Initial Price) / Initial Price * 100

Percentage Change in Price of Good X = (5 - 4) / 4 * 100 = 25%

Now, we can calculate the cross-price elasticity of demand:

Cross-Price Elasticity of Demand = Percentage Change in Quantity Demanded of Good Y / Percentage Change in Price of Good X

Cross-Price Elasticity of Demand = 25% / 25% = 1

b. Based on the calculated cross-price elasticity of demand, we can determine the types of goods:

If the cross-price elasticity of demand is positive (as in this case, where it is 1), it indicates that the two goods are substitutes. This means that when the price of good X increases, the quantity demanded of good Y also increases, suggesting that consumers view these goods as alternatives to each other.

Therefore, based on the cross-price elasticity of demand, we can conclude that good X and good Y are substitutes.

Answer:

The increase in the level of confidence means that the interval will be wider.

Step-by-step explanation:

Margin of error of a confidence interval:

The margin of error of a confidence interval has the following format:

\(M = z\frac{s}{\sqrt{n}}\)

In which z is related to the confidence level(if the confidence level increases z increases), s is related to the standard deviation and n is the sample size.

The higher the margin of error, the wider the interval is.

In this question:

Increasing the level of confidence will mean an increase in z, and thus, since M and z are directly proportional, the margin of error will increase, and the inteval will be wider.

Step-by-step explanation:

In order to find the total cost of the rides you would have to multiply the rides by their cost and then add on the entrance fee, however if you were to find the number of rides you would have to divide the total cost by 4 and then subtract 12 leaving the number of rides made.

r(x)=x-6

s(x) = 2x²

(r + s)(x) = r(x) + s(x) = x - 6 + 2x² = 2x² + x - 6

(r*s)(x) = r(x)*s(x) = (x - 6)(2x²)

Using distributive property:

(r*s)(x) = 2x³ - 12x²

(r - s)(-2) = r(-2) - s(-2) = (-2-6) - 2(-2)² = -8 - 8 = -16

The expression (sinx + cosx)^2 + (sinx - cosx)^2 simplifies to

If John solved the equation x² - 10x + 8 = 0 by completing the square, one of the steps in his process would be: A. (x - 5)² = 17.

In Mathematics, the standard form of a quadratic equation is represented by the following equation;

ax² + bx + c = 0

Next, we would solve the given quadratic equation by using the completing the square method;

x² - 10x + 8 = 0

x² - 10x = -8

In order to complete the square, we would have to add (half the coefficient of the x-term)² to both sides of the quadratic equation as follows:

x² - 10x + (-10/2)² = 8 + (-10/2)²

x² - 10x + 25 = -8 + 25

x² - 10x + 25 = 17

By simplifying, we have;

(x - 5)² = 17
