The ------------- of a circle is a line segment that joins two points on the circumference of the circle and passes through the centre of the circle

Answer:

1/5

Step-by-step explanation:

a reciprocal is the multiplicative inverse

Answer:

The reciprocal of 5 is 1/5

Step-by-step explanation:

The reciprocal of a number is the fraction flipped upside down

6/1    =  1/6

⇒ 5/1 =    1/5

(1, 42)

1) Since we have an equation of the line y = 2 + 5(x + 7) let's find one point that ∈ to this line.

2) Let's plug into that for x, the value of x=1

y= 2+ 5(1+7)

y= 2 +5(8)

y= 2 +40

y= 42

3) So one of the points that lie on this line is (1, 42) i.e. belong to that line.



In this problem, we have the transformation

A(-3,4) -------> A'(-15,20)

A box and whisker plot is a graphical representation of variance in a set of data. A histogram analysis is sufficient in most circumstances, but a box and whisker plot can provide more detail while allowing different sets of data to be displayed in the same graph.

The box and whisker figure highlights data on the number of Broadway tickets sold and actual attendance at the performances. In this case, the graph shows that the number of tickets are more.

At least 26 bags of cat chow is required for a period of one year to fulfil the demand at the wildlife shelter in North Carolina

Quantity of cat chow sold in each bag = 20 lb

Consumption in lb of cat chow per week in the wildlife shelter = 10 lb

Number of weeks in a year = 52 weeks

The total quantity of cat chow required for 52 weeks = Weekly consumption of cat chow*Number of weeks

= 10*52

= 520 lb

Number of bags required = Toal quantity of cat chow required for 52 weeks/ Quantity of cat chow sold in each bag

= 520/20

= 26 bags

The middle value in a sorted, ascending or descending list of numbers is known as the median, and it has the potential to describe a data collection more accurately than the average does.

A data set is a group of figures or values related to a specific topic. a list of words, numbers, or symbols, the values of which are frequently the outcomes of an investigation or observation. There are typically multiple variables in data sets.

A dataset is an organized group of data typically connected to a certain body of work. An organized collection of data kept as several datasets is called a database.

In an ordered data set, the median is the value in the middle. The mean is calculated by dividing the sum of all values by the total number of values. The middle value in a sorted, ascending or descending list of numbers is known as the median, and it has the potential to describe a data collection more accurately than the average does.

The associated matrix associated to the linear transformation is A = [tex]\left[\begin{array}{cc}5&-6\\1&- 3\\8&- 2\\0 & - 4\end{array}\right][/tex].

Linear transformations are applications between two vector spaces that preserves the properties of vector addition and the product of a vector and a scalar. In this problem, we find the following linear transformation between the two bases:

W → V

(w₁, w₂, w₃, w₄) → v₁

Then, there is the following relationship:

V = A · W

Where A is the associated matrix. The matrix V has four rows and one column and the matrix W has two rows and one column. Then, by property of multiplication of matrices, the associated matrix has four rows and two columns. Then, the associated matrix is:

The window has a length of 21 inches

From the question, we have the following parameters

Area of the window = 336 square inches

Width of the window = 16 inches

The area of the window is the product of its dimensions

So, we have

Area = Width of the window x Length of the window

Substitute the known values in the above equation

So, we have the following equation

336 = 16 * Length

Divide both sides by 16

Length = 21

Vectors, matrices, vector spaces, and linear transformations are all topics covered in the mathematical field of linear algebra. Linear algebra is much better understood than other areas of mathematics, which are regularly stimulated by novel concepts and unresolved issues.

According to the question,

Let Mathew spent $x

lan spent = 2x - 20

Total money spent = $130

⇒ 2x - 20 + x = 130

⇒ 3x - 20 = 130
