The distance between the points (-4, -5) and (8, 0) is 13 units

The coordinates of the first point = (-4, -5)

The coordinates of the second point = (8, 0)

The distance between the two points d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Where d is the distance between two points

[tex](x_1,y_1)[/tex] is the coordinates of the first point

The number of hours that it takes for Paul to do the job alone is of:

6 hours.

The time that it takes for Paul to do the job alone is given by the together rate, which is obtained as the sum of the separate rates.

The rates in the context of this problem are given as follows:

Hence the value of x is obtained applying the together rate, and it gives the number of hours that it takes for Paul to do the job alone.

Hence:

1/(x - 2) = 1/x + 1/12

1/(x - 2) = (12 + x)/(12x)

Applying cross multiplication, we have that:

(12 + x)(x - 2) = 12x

x² + 10x - 24 = 12x

As per the concept of direct variation, y = 80 when x = 5, then the direct variation equation shows the relationship between x and y will be y = 16x

Equation

Basically, the equation is a statement that two expressions, which include variables and/or numbers, are equal. And in essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

Given,

In a direct variation, y=80 when x=5.

Here we have to write a direct variation equation that shows the relationship between x and y.

Here we have given that,

The value of y = 80 when x = 5

Therefore, there are often two different sorts of variables in analytics.

And we have obtained that independent variables will have an impact on dependent variables.

Now, what occurs as a result of the independent variable is referred to as a dependent variable.

Here we have given equation x is the independent variable while y is the dependent variable.

So, it can be written as,

=> 80 = 16(5)

Therefore, the resulting equation is y = 16x

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that x is a non-negative number, a student conjectured that x + 4 < x².

Since x is a non-negative number, A and B are eliminated.

Maya is playing a trivia game with multiple choice questions. Each question has 222 correct answers among 555 answer choices. Maya has no idea what the answers to a certain question are, so she needs to choose two different answers at random.

The probability that maya's first guess is correct and her second guess is incorrect is 0.24.

From the question given above, the following data were obtained:

Correct answer (C) = 222

Total answer = 555

Incorrect answer (I) = 555 – 222 = 333

Next, we shall determine the probability that her 1st guess is correct.

Correct answer, nC = 222

Total answer, nS= 555

Probability of correct answer, P(C) =?

P(C) = nC / nS

P(C) = 222 / 555

Next, we shall determine the probability that her 2nd guess is incorrect

Incorrect answer, nI = 333

Total answer, nS = 554

Probability of incorrect answer, P(I) =?

P(I) = nI / nS

P(I) = 333 / 554

Finally, we shall determine the probability that her first guess is correct and her second guess is incorrect.

Probability of correct answer, P(C) = 222 / 555

Probability of incorrect answer, P(I) = 333 / 554

Probability of 1st correct and 2nd incorrect, P(C n I) =?

P(C n I) = P(C) × P(I)

P(C n I) = (222 / 555) × (333 / 554)

P(C n I) = 0.24

Hence the answer is, The probability that maya's first guess is correct and her second guess is incorrect is 0.24.

The value of h in a regular polygon of 16 sides is 37.3.

According to the question,

We have the following information:

A regular polygon has 16 sides. And one of its angles measures (5h − 29)°.

We know that following formula is used to find the sum of interior angles of a polygon:

(n-2)*180 where n is the number of sides of a polygon

(16-2)180

14*180

2520°

Now, in this polygon, there are 16 sides. So, there will be 16 angles.

Now, to find the measurement of one angle, we will divide total sum by number of angles.

One angle = 2520/16

One angle = 157.5°

Now, we have the following expression:

5h-29 = 157.5

5h = 157.5+29

5h = 186.5

h = 186.5/5

h = 37.3

Hence, the correct option is B (the second one).

The probability of selecting four cards of the same suit is 0.0106.

A probability is a number that reflects the chance or likelihood that a particular event will occur.

Given that, four cards are selected at random without replacement from a well-shuffled deck of 52 playing cards

No. of cards for each suit = 13

Total types of four suits = 4(hearts, spades, diamond, clubs)

Probability = (conditional case)/(total case)

So, total number of conditional case = No. of case of selecting all 4 cards of hearts suit + no. of case of selecting all 4 cards of spades suit + no. of case of selecting all 4 cards of clubs suit + no. of case of selecting all 4 cards of diamonds suit

= 13C4 + 13C4 + 13C4 + 13C4

= 4*13C4 = 4*13!/9!4! = 4*13*12*11*10*9!/9!*4*3*2*1 = 2860

Total number of cases = 52C4 = 52!/48!4! = 270725

So, probability of getting all 4 cards of the same suit =

2860/270725

put x= 0 and find y

y = 0 + 5

y = 5

put y = 0 and find x

0 = -1/3 x + 5

-5 = -1/3 x

Where:

P is the initial amount, here we know that it is $5,300

r is the rate, in this case is 8%, but it needs to be written as a decimal, so we have r = 0.08

t is the variable, this time is the time in years, we want to find the amount owed after 6 years, so t = 6

n is how many the the rate applies on one unit of t, in this case the rate is monthly, and there are 12 months on a year, so n = 12.

Your posted question asks for the value of C (capitalized). That refers to the right angle, so its value is C = 90°. It is always helpful if you ask for what you really want to know.

The perimeter of the triangle is, 8x + 3y +1.

What is perimeter?

A perimeter is a closed path that encloses, surrounds, or delimits a one-dimensional length, a two-dimensional shape, or both. The circumference of a circle or an ellipse is its perimeter. There are numerous practical uses for calculating the perimeter.

Let, the side lengths of the triangle are (7x - 4), (x + 3) and (3y + 2).

Since the perimeter is the sum of all side lengths.

So,

Perimeter = (7x - 4) + (x + 3) + (3y + 2)

                 = 7x - 4 + x + 3 + 3y + 2

Perimeter = 8x + 3y + 1

Hence, the perimeter of the triangle is, 8x + 3y + 1.

Graph (B) represents the base function f (x)=√x and the stretched function [tex]g (x) = \frac{-3}{2} \sqrt{x}[/tex].

Graphs are used to map functions of two variables on a Cartesian coordinate system, which is composed of a horizontal x-axis, vertical y-axis.

The graph of this function can be obtained by putting different values of x.

x = 0 gives f (x) = 0

x = 1 gives f (x) = 1

x = 2 gives f (x) = 1.414

x = 3 gives f (x) = 1.732

Drawing these points in the graph and connecting we get a curve(black) which can be seen in all  given diagram (A), (B), (C), (D).

Now, we have stretched function  [tex]g (x) = \frac{-3}{2} \sqrt{x}[/tex]

The graph of this function can be obtained by putting different values of x.

x = 0 gives g (x) = 0

x = 1 gives g (x) = -1.5

x = 2 gives g (x) = -2.121

x = 3 gives g (x) = -2.598

Drawing these points in the graph and connecting we get a curve(red) which can be seen in diagram (D).
