Answer:

23.54

Step-by-step explanation:

The required values of slope and y-intercept are 10 and 15.

The formula for these lines is y = mx + b, where m denotes the slope and b the y-intercept. Our line has a slope of 3 and a y-intercept of -5, which we know from the question. By entering these numbers, we obtain the equation of our line as y = 3x - 5.

We have,

y = 10x + 15

On comparing with general equation of line.

Y = mx + c

m is slope of line, c is y-intercept.

Then,

m = 10

And

y-intercept = 15

Thus,the required values of slope and y-intercept are 10 and 15.

The set of polynomials is not closed under division.

A polynomial is a mathematical statement made up of exponents, constants, and variables that are mixed using addition, subtraction, multiplication, and division operations. Polynomial means "many terms" since it combines the words poly-, which means "many," and -nomial, which in this context means "term." A polynomial may have exponents (like the 2 in y2), constants (like x and y), variables (like the x and y exponents), and other terms, but only those that can be mixed using addition, subtraction, multiplication, and division are permitted. Constants, variables, and exponents are all permitted in polynomials, but variable division is never permitted.

In addition, they are now only limited to a finite number of terms, which can be one or more.

The dividend appears at the top of the division at first, similar to how long multiplication is written.

As given in the question,

Given points of the line segments are :

( x₁ , y₁ ) = ( -2 , -3 )

Simultaneous linear equations are a pair of linear equations in two or three variables that are solved simultaneously to arrive at a single answer.

Simultaneous equations are two or more algebraic equations that share the same unknown variables and have the same solution for each of them. The simultaneous equations must therefore have a single solution, according to this.

Add together the equations if the signs vary. Subtract the indications from one another if they match. Different Add, Same Subtract, or DASS, is a simple way to remember this.

A possible second point with a y-coordinate of 8 is equal to 5.

In Mathematics, the slope of a straight line can be calculated by using this this mathematical expression;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

From the information provided above, we have the following slope and data points on the line:

Points on x-axis = (1, 2).

Points on y-axis = (_, 8).

Slope, m = 3/2

Substituting the given points into the slope formula, we have the following;

Slope, m = (y₂ - y₁)/(x₂ - x₁)

3/2 = (8 - 2)/(x₂ - 1)

3/2 = 6/(x₂ - 1)

Cross-multiplying, we have:

3(x₂ - 1) = 12

x₂ - 1 = 12/3

x₂ - 1 = 4

x₂ = 4 + 1

x₂ = 5

The relationship between x and y in the table appears to be a linear, proportional relationship. One way to write an equation for this relationship is using the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

To find the slope (m), we can use the formula: m = (y2 - y1) / (x2 - x1).

Using any two points from the table, like (x1, y1) = (0.5, 7) and (x2, y2) = (1, 14)

m = (14 - 7) / (1 - 0.5) = 7 / 0.5 = 14

So the slope (m) = 14, which means that y increases by 14 units for every unit increase in x.

Then we can use any point in the table to find the y-intercept (b)

Using the point (1,14)

14 = 14*1 + b

b=0

So the equation for the proportional relationship shown in the table is : y = 14x

The 25th percentile for the given dataset is 5, and the 80th percentile is 16.

What is the percentile?

A percentile is a measure used in statistics that indicates the value below which a given percentage of observations in a group of observations fall. Percentiles divide a set of observations into 100 equal parts, where each part represents 1% of the observations.

To find the 25th percentile (also known as the first quartile) and 80th percentile (also known as the fourth quartile) for a set of data, you can use the following steps:

Arrange the data in increasing order:

1, 3, 5, 9, 10, 11, 14, 15, 16, 18, 20, 22, 24, 25, 27, 29, 31, 37

To find the 25th percentile, use the following formula:

25th percentile = (N+1) x 25%

where N is the number of observations. In this case, N = 18.

Plugging in the values, we get:

25th percentile = (18+1) x 25% = 19 x 25% = 4.75

So, the 25th percentile is the 4.75th value in the ordered list. Rounding up to the nearest whole number, we get 5 as the 25th percentile.

To find the 80th percentile, use the following formula:

80th percentile = (N+1) x 80%

where N is the number of observations. In this case, N = 18.

Plugging in the values, we get:

80th percentile = (18+1) x 80% = 19 x 80% = 15.2

So, the 80th percentile is the 15.2th value in the ordered list. Rounding up to the nearest whole number, we get 16 as the 80th percentile.

Hence, the 25th percentile for the given dataset is 5, and the 80th percentile is 16.

∠B = 99°

side length of AC = 16

a / sin A = b / sin B = c / sin C

A = ½( a+b) h

where a and b are the parallel sides and h is the height of the trapezium.

since the lawn takes the shape of a trapezium,

The height of the lawn is calculated as:

h² = 17²- 8²
