No, not all square numbers have an odd number of factors. In fact, square numbers can have either an odd or an even number of factors, depending on their prime factorization.

A square number is a number that can be expressed as the product of an integer multiplied by itself. For example, 4 is a square number because it can be written as 2 * 2.

When we analyze the factors of a square number, we find that each factor has a corresponding pair that multiplies to give the square number. For instance, the factors of 4 are 1, 2, and 4. We can see that the pairs are (1, 4) and (2, 2). Thus, 4 has an even number of factors.

However, there are square numbers that have an odd number of factors. Consider the square number 9, which is equal to 3 * 3. The factors of 9 are 1, 3, and 9. In this case, 9 has an odd number of factors.

In conclusion, while some square numbers have an odd number of factors (like 9), others have an even number of factors (like 4). The determining factor is the prime factorization of the square number.

The length of the diagonal AB of the cube is 8.7 cm.

Length of a face diagonal of cube = √2a, where a = Length of each side of a cube.

Length of body diagonal of a cube = √3a, where a = Length of each side of a cube.

Given:

Side length of the cube(a) = 5 cm

We have to find the length of the diagonal AB which is a body diagonal.

Length of Body diagonal(AB) = √3a

Substituting the given value in the formula,

Length of the body diagonal of cube = √3a

⇒ √3a ⇒√3 × 5 = 8.7 cm

Therefore, the length of AB i.e. the body diagonal of the cube is 8.7 cm.

The center of the track as a function of the measure of the angle of rotation (in radians) from the 3 o'clock position.

Sure, I can help you with that! To define the function f, we need to use the distance and angle information given in the problem. The distance of the car from the center of the track is constant at 4 feet, so we can use that as a fixed value in our function.

Now, we need to consider the measure of the angle of rotation, 6, which is given in radians from the 3 o'clock position. We can use this angle to determine the horizontal distance of the car from the center of the track.

To do this, we can use the formula for the circumference of a circle: C = 2πr, where C is the circumference, r is the radius (which is 4 feet in this case), and π is the constant value of approximately 3.14159.

Since the car is at a certain angle from the 3 o'clock position, we can use this angle to find the length of the arc of the circle that the car has traveled. The length of an arc of a circle is given by the formula L = rθ, where L is the length of the arc, r is the radius, and θ is the measure of the angle in radians.

So, to find the horizontal distance of the car from the center of the track, we can use the formula d = L sin(θ), where d is the horizontal distance, L is the length of the arc, and θ is the measure of the angle in radians.

Putting all of this together, we can define the function f as follows:

f(θ) = 4 sin(θ)

This function models the toy race car's distance to the right of the center of the track (in feet) as a function of the measure of the angle of rotation, θ (in radians) from the 3 o'clock position.

I'm not sure what to solve, but I assumed that you wanted to know the unit price.

Since none of the 13 classmates had been given math homework between the original survey and Kelly's second survey, the sum of the values in the second data set is the same as the sum of the values in the original data set. Therefore, the change in the means can be determined without calculating the mean of either data set by considering the number of data points in each set.

Since both data sets have the same number of data points, the change in the means will be zero. This is because the mean is calculated by dividing the sum of the values by the number of data points, and since the sum of the values is the same in both data sets, the means will also be the same.

In other words, if the mean of the first data set is x, then the sum of the values in the first data set is 13x (since there are 13 classmates), and the sum of the values in the second data set is also 13x (since none of the values have changed). Therefore, the mean of the second data set will also be x, and the change in the means will be zero.

The difference of squares: a² - b² factors to (a - b) (a + b)

Let x⁴ = (x²)²

Let 16 = 4²

Now by difference of squares x⁴ - 16 factors as (x² - 4)(x² + 4)

The front factor, (x² - 4), can factor by difference of squares again as (x - 2)(x + 2)

Answer:

45 degrees

Step-by-step explanation:

The sum of the angles of a triangle always adds up to 180.

10x + 8x + 5 + 85 = 180

Simplify by combining like terms.

18x + 90 = 180

Subtract 90 from both sides.

18x = 90

Divide both sides by 18.

x = 5 degrees

But the question didn't ask for x, it asked for angle A. So plug back in.

A = 8x + 5

A = 8(5) + 5

A = 40 + 5 = 45 degrees

Answer:

\(45 \: \: degrees\)

Step-by-step explanation:

\(10x + 8x + 5 + 85 = 180 \\ 18x + 90 = 180 \\ 18x = 180 - 90 \\ 18x = 90 \\ \frac{18x}{18} = \frac{90}{18} \\ x = 5\)

\(angle \: \: \: a = 8x + 5 \\ = 8 \times 5 + 5 \\ = 40 + 5 \\ = 45 \: \: degrees\)

Answer:

The answer is D

Step-by-step explanation:

The decimal number 3.16 in the form of the simplest fraction is 79/25.

The portion or part of the complete item is represented by a fraction. It stands for the equal components of the whole. The denominator and numerator are the two components of a fraction. The top number is referred to as the numerator, and the bottom number is referred to as the denominator.

Consider the decimal number,

Let x = 3.16

Then,

x = 3.16 = 316/100

The fraction then can be simplified as,

x = ( 158 × 2)/ (50 × 2)

x = 158/50

x = ( 79 × 2)/ ( 25 × 2 )

x = 79/25

Hence, the number 3.16 in the simplest fraction is 79/25.

The predicted leaf weight in the percent which is left after 80 days is equal to 67.03%.

Number of days after which predict the percent leaf weight left = 80 days

Experimentally determined k-value =  0.005,

Use the exponential decay model for leaf litter decomposition,

W(t) = W0 × e^(-kt)

where W(t) is the predicted percent leaf weight remaining at time t,

W0 is the initial percent leaf weight at time 0,

k is the decomposition rate constant,

And e is the mathematical constant approximately equal to 2.71828.

Using the given k-value of 0.005

And assuming an initial weight of 100%,

Plug in the values to get,

⇒ W(80) = 100 × e^(-0.005×80)

⇒ W(80) = 100 × e^(-0.4)

⇒ W(80) ≈ 67.03

Therefore, the predicted percent leaf weight left after 80 days is approximately 67.03%.

Answer:

Yo Rick Astley

Step-by-step explanation:

y ∝ 1 √ x

y = k (1 √ x)

y = 7 when x = 36

7 = k ( 1 / √36)

7 = k (1/6)

k= 7 × 6

k = 42

If x = 4 then,

y = 42 ( 1/√4)

y = 42 ( 1/2)

y= 21

The equation of the line in slope intercept form is y = -2.65x + 25.

The x-intercept means when the gift card has a balance of zero dollars.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

Therefore. let's find the slope of the line using (2, 19.7) and (4, 14.4).

Hence,

m = slope = 14.4 - 19.7 / 4 - 2

m = - 5.3 / 2

m = - 2.65

Therefore, let's find the y-intercept using (2, 19.7).

y = -2.65x + b

19.7 = -2.65(2) + b

b = 19.7 + 5.3

b = 25

Therefore, the equation of the line is y = -2.65x + 25.

The x-intercept is the value of x when y = 0.

Hence,

0 = -2.65x + 25

-25 = -2.65x

x = -25 / -2.65

x = 9.4

The x-intercept means the gift card has zero balance. At this point the medium cup of coffee is 9.4 .
