Which letter on the number line represents one and eighty five hundredths?

The length of the leg of the 45-45-90 triangle is 6.

In geometry, the hypotenuse is the longest side of a right-angled triangle, opposite to the right angle.

The longest side of a right-angled triangle, or the side opposite the right angle, is known as the hypotenuse in geometry. The Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides, can be used to determine the length of the hypotenuse.

In a 45-45-90 triangle, the length of each leg is equal to x, and the length of the hypotenuse is √2 times the length of a leg.

So if the hypotenuse is 6√2, then each leg has length:

x = (6√2)/√2 = 6

Hence, the length of the leg of the 45-45-90 triangle is 6.

The first digit in both numbers is 2, so we can move to the next digit. In 2.218, the digit in the second decimal place is 2, while in 2.21, the digit in the second decimal place is 1. Since 2 is greater than 1, 2.218 is longer than 2.21.

When comparing the length of two decimal numbers, it's important to consider the value of each digit in the number. Let's take the example of 2.218 inches and 2.21 inches.

To begin, we can compare the first digit of each number, which is 2 in both cases. Since the first digit is the same, we need to look at the next digit to determine which number is longer. In 2.218, the second digit is 2, while in 2.21, the second digit is 1. The second digit in a decimal number represents the tenths place, so we can conclude that 2.218 is longer than 2.21.

It's important to note that this method of comparing decimal numbers applies to numbers with the same number of decimal places. If we were comparing 2.218 inches to 2.2 inches, for example, we wouldn't be able to simply look at the second digit. Instead, we would need to compare the numbers digit by digit, starting from the leftmost digit.

The formula for the average rate of change to get is:

average rate of change = (y2 - y1) / 5

What is the average rate of change?

The average rate of change means the average rate at which one quantity is changing with respect to something else changing.

To find the average rate of change of a function f(x) over an interval [a, b], we can use the formula:

average rate of change = (f(b) - f(a)) / (b - a)

In this case, we are given the function f(x), but we don't have a formula for it. Instead, we are given the interval [2, 7] over which we want to find the average rate of change. So, we can use the values of the function at x = 2 and x = 7 to compute the average rate of change.

Let's assume that we have the function f(x) and evaluate it at x = 2 and x = 7 to get:

f(2) = y1

f(7) = y2

Then, we can use the formula for the average rate of change to get:

average rate of change = (f(7) - f(2)) / (7 - 2) = (y2 - y1) / 5

So, to find the average rate of change of f(x) over the interval 2 ≤ x ≤ 7, we need to know the values of f(2) and f(7). If these values are given or can be calculated, we can use the formula above to find the answer.

Hence,  the formula for the average rate of change to get is:

average rate of change = (y2 - y1) / 5.

29x+2=30x-1

Subtract 29x to both sides:

2=x-1

Add 1 to both sides:

x=3

Now we will solve for y. Using alternate angles, both expressions are equal to y, we can pick any.

30x-1=y

∫ 8 (x+a)(x+b) dx = (8/3)x³ + 4x²(a+b) + 8x(ab) + c

The antiderivative of 8 (x+a)(x+b) with respect to x is (8/3)x³ + 4x²(a+b) + 8x(ab) + c.

To evaluate the integral, we can use the distributive property to expand the expression in the integrand:

8 (x+a)(x+b) dx = 8(x² + (a+b)x + ab) dx

We can then integrate each term separately using the power rule of integration:

∫ 8(x² + (a+b)x + ab) dx = (8/3)x³ + 4(a+b)x² + 8abx + c

We can simplify this result by factoring out the constant 8/3 from the first term and using the distributive property to factor out the common factor of 4x from the last three terms:

(8/3)x³ + 4(a+b)x² + 8abx + c = (8/3)x³ + 4x²(a+b) + 8x(ab) + c

We can check our answer by taking the derivative of the result to see if it matches the original integrand. The derivative of (8/3)x³ is 8x², the derivative of 4x²(a+b) is 8x(a+b), the derivative of 8x(ab) is 8ab, and the derivative of the constant c is 0. Adding these terms together, we get the original integrand of 8(x+a)(x+b) dx, so our answer is correct.

A logarithmic function is a type of mathematical function that relates two quantities by the use of logarithms. In particular, a logarithmic function describes the relationship between the input (or independent variable) and the output (or dependent variable) in terms of the logarithm of the input.

The general form of a logarithmic function is:

f(x) = loga(x)

where f(x) is the output, x is the input, and a is the base of the logarithm The logarithm of a number x with respect to a base a is the power to which a must be raised to obtain x. For example, if a is 10, then log10(100) = 2, because[tex]10^2[/tex] = 100.

Logarithmic functions are useful for expressing quantities that vary over a large range of values, such as the brightness of stars or the acidity of solutions. They can also be used to solve exponential equations or to represent data that follows a certain pattern.

In particular, logarithmic functions have the property that they can "undo" exponential functions. That is, if we have an exponential function f(x) =[tex]a^x[/tex], then its inverse function is given by [tex]f^-1(x)[/tex] = loga(x). This property is often used in calculus and other areas of mathematics.

Logarithmic functions can be graphed in a variety of ways, depending on the base and other parameters of the function. The graph of a logarithmic function typically looks like a curve that gets steeper as it moves away from the origin.

In summary, a logarithmic function is a type of mathematical function that relates two quantities by the use of logarithms. They are useful for expressing quantities that vary over a large range of values and can "undo" exponential functions.

C. f(x) = 6x – 4 --> f(2) = 6(2) - 4 = 8 (not a match)

D. f(x) = –4x – 4 --> f(2) = -4(2) - 4 = -12 (not a match)

Therefore, the equation of the function could be f(x) = 4x + 4 (option B).

Dot plot 2, on the other hand, is skewed and does not have a symmetrical distribution, which may not be a good representation of the sample means.

What is normal distribution ?

Normal distribution is a statistical concept that describes a symmetrical, bell-shaped curve that is characterized by its mean and standard deviation. It is a continuous probability distribution that represents the probability of a random variable taking on a certain value.

As per the Central Limit Theorem, the sample means of a sufficiently large sample size taken from any population tend to follow a normal distribution, regardless of the shape of the population distribution. Therefore, the dot plot that is likely to represent the means of the samples of size 10 from this population is dot plot 1 because it has a more symmetrical distribution, which is more similar to a normal distribution.

Hence, Dot plot 2, on the other hand, is skewed and does not have a symmetrical distribution, which may not be a good representation of the sample means.
