An ellipse's form is determined by two locations inside the ellipse known as its foci.

The lengths of the main and minor axes of an ellipse may be used to calculate its foci.

The foci of an ellipse may be calculated using a variety of online calculators.

These calculators normally ask the user to enter the main and minor ellipse axes' lengths before calculating the foci's coordinates. Depending on the calculator in question, some may additionally ask for more details like the ellipse's eccentricity or center of rotation.

Understanding an ellipse's shape and characteristics requires knowing its foci since they are what characterize an ellipse.

110 - 16 = 10h

110 = 16 + 10h

The correct options are the first and fourth options

From the question, we are to determine the equation that could be solved to determine Sylvie's hourly earnings

The equation that represent the total amount Sylvie needs to earn more is

$110 - $16 = $94

and the total number of hours she will work is 10 hours,

Then,

The equation for her hourly earning's, h, is

10 × h = $96

Thus, we can write that

10h = 96

OR

10h = 110 - 16

We will find the equations that are equivalent to this.

The equation that are equivalent to the above equations are

110 - 16 = 10h

The total amount spent when the 10 items are bought is $97.17.

The final temperature given the increase in temperature and the decrease in temperature is 18 degrees.

In order to determine if your friend has enough money to buy all the items, the total cost of the items have to be determined. The total cost is the sum of all the items bought.

here, we have,

Total cost = total cost of the first three items + total cost of the second three + total cost of the last three

Total cost = (3 x 15.99) + (3 x 10.40) + (4 x 4.50)

Total cost = $47.97 + $31.20 +18

Total cost = $97.17

An increase in temperature would be represented with a positive number. While, a decrease in temperature would be represented with a negative number. The final temperature can be determined by adding the temperature increase and decease together.

To discover the coordinates of a polar point, you need to recognize its distance from the origin (the polar axis) and the perspective it makes with the superb x-axis.

The space is commonly denoted via the image r, and the angle is denoted by means of the image θ. To devise a polar point, you start by locating the foundation and drawing a line alongside the polar axis.

Subsequently, you measure the angle θ from the fine x-axis, shifting counterclockwise.

In the end, your degree the distance r from the starting place and plot the factor on the corresponding location.

To find the coordinates of a polar point, you can use the subsequent formulas:

x = r cos(θ)

y = r sin(θ)

Right here, x and y constitute the rectangular coordinates of the factor, while r and θ constitute the polar coordinates.

The coefficient of variation (CV) calculator is a tool that helps you calculate the relative variability of a dataset. The coefficient of variation is the ratio of the standard deviation (SD) to the mean (μ) expressed as a percentage, and it is used to compare the variability of datasets with different units or scales.

The formula for the coefficient of variation is:

CV = (SD / μ) x 100%

To use a coefficient of variation calculator, you need to input the values of the dataset, either one by one or as a list, and select the type of data you have (sample or population). The calculator will then calculate the mean, standard deviation, and coefficient of variation of the dataset.

The coefficient of variation is commonly used in quality control, finance, and other fields to compare the variability of different datasets. A high coefficient of variation indicates that the dataset has a large amount of variability relative to the mean, while a low coefficient of variation indicates that the dataset has a small amount of variability relative to the mean.

The coefficient of variation is only meaningful when the mean is non-zero. If the mean is zero or close to zero, the coefficient of variation can be infinite or undefined.

The scale factor of the preimage to the image is 5/2

The length of BC is 10 units

The scale factor is the size by which the shape is enlarged or reduced. It is used to increase the size of shapes like circles, triangles, squares, rectangles, etc.

The scale factor of the preimage to the image can be found by finding the ratio of the corresponding sides of the preimage to the image. That is:

scale factor = DC / D'C'

scale factor = 5/2

Also, the scale factor = BC / B'C' and the scale factor is constant (i.e. 5/2)
