a. The y coordinate of the center of the circle is -1.

b. The value of b in the equation is 44 units.

The solution has been obtained using circles.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.

a. We are given the equation as

x² + y² - 4 x + 2 y = b

On solving the equation, we get

x² - 4 x + 4 + y² + 2 y + 1 = b + 4 + 1

This can be written as

( x - 2 )² + ( y + 1 )² = b + 5   ...(1)

So, the y - coordinate of the center of the circle is - 1.

b. We know that equation of circle is

( x - a )² + ( y - c)² = r²

On comparing this with (1), we get

b + 5 = r²

b + 5 = 7²

b + 5 = 49

b = 49 - 5

b = 44

Hence, the value of b is 44 units.

Answer:

10

Step-by-step explanation:

whole circle area = π r² = π*7² =49π

60 = 1/6 of the circle

so 49π/6 is the slice area

then minus the triangle area

triangle area =1/2*6* height

height² =6²-3² =36-9 = 27

so height = 5.2

triangle area =1/2*6* 5.2 =15.6

so the sliver = 49π/6 -15.6 =10

The mode of this set of numbers is 1,the median of this set of numbers is 1.

Mean: To find the mean of this set of 5 numbers, we first add them together and divide by the number of measurements. 0 + 7 + 1 + 1 + 4 = 13. 13 divided by 5 (the number of measurements) is 2.6. Therefore, the mean of this set of numbers is 2.6.

Median: To find the median of this set of 5 numbers, we first need to arrange them in order from least to greatest. 0, 1, 1, 4, 7. The median is the middle number, so it is 1. Therefore, the median of this set of numbers is 1.

Mode: To find the mode of this set of 5 numbers, we need to look for the number that appears most often. In this set, the number 1 appears twice while the rest of the numbers appear only once. Therefore, the mode of this set of numbers is 1.

The equation p = 8.25 + 3 inches can be used for finding the length p of the plank before chandler cuts it.

Addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

In mathematics, addition is the process of joining two or more integers. The numbers being added are known as addends, and the result or final response obtained after the procedure is known as the total.

From the given data,

The length of the plank cut by the chandler =3 inches

The correct length = 8.25 inches.

So, for finding the value of the length p of the plank before the chandler cuts, we will add the value of the correct length and the length of the plank cut by the chandler.

So, the value of p will be: 8.25+3 = 11.25 inches.

Therefore , the solution of the given problem of mean comes out to be on total  he gets $2.00 from the bags.

A dataset's mean is the sum of all values divided by the total number of values, often known as the arithmetic mean (as opposed to the geometric mean). Often referred to as the "mean," this is the most often used measure of central tendency. Simply dividing the dataset's total number of values by the sum of all of those values yields this result. Both raw data and data that have been combined into frequency tables can be used for calculations.

A rational number p/q has a terminating base 60 representation if q is a factor of 60. This can be proven by noting that q is a factor of p if and only if the remainder of p divided by q is 0. For any base n, q must be a factor of n in order for p/q to have a terminating base n representation.

A rational number p/q has a terminating base 60 representation if q is a factor of 60. This can be proven by noting that q is a factor of p if and only if the remainder of p divided by q is 0. This can be seen by noting that if q is a factor of p, then p can be written as a multiple of q, or p = kq, where k is an integer. Thus, p/q = k, and the remainder of p divided by q must be 0. If q is not a factor of p, then the remainder of p divided by q will not be 0. Thus, for a rational number p/q to have a terminating base 60 representation, q must be a factor of 60. To determine if q is a factor of n for any base n, we must again consider the remainder of p divided by q. If the remainder of p divided by q is 0, then q is a factor of n, and the rational number p/q will have a terminating base n representation. If, however, the remainder of p divided by q is not 0, then q is not a factor of n and the rational number p/q will not have a terminating base n representation.

What is binary ?

A binary number is a number expressed in the base-2 numeral system or binary numeral system, a method of mathematical expression which uses only two symbols: typically "0" and "1".

An irreflexive closure is a mathematical concept that refers to the creation of a new binary relation from a given binary relation by adding the property of irreflexivity. A binary relation is irreflexive if it does not relate any element to itself. The irreflexive closure of a binary relation is the smallest irreflexive relation that contains it.

In other words, the irreflexive closure of a binary relation is a modified version of the original relation where no element is related to itself. The process of finding the irreflexive closure involves removing all self-referential relationships and adding new relationships to preserve the original relationships between elements.

An injective function, also referred to as a one-to-one function, is a mapping between two sets that accounts for a range for each domain.

Onto functions or surjective functions when a range to a domain mapping involves more than one element.

These coordinates are (x,y)

Let's subtract the X's

Next, you would add these together

-2+4 = 2

Last step is squaring rooting this number

✓2, you can either find the actual square root by calculator or leave it as ✓2. This would be your distance.

Finding the midpoint is like the average. Right in the middle. So you would do the same with these.

To find X you'll add them then divide by 2 since there are 2 x coordinates
