The set notation will be S ∈ { 14, 16, 18, 20, 22, 24, 26, 28}.

When we have to represent set having defined specific number, we do my writing the number in curly bracket. When we have to represent the set having collection of continuous number between two specific defined number, we do by writing first and last number in small bracket.

As the terms given for the set is 14, 16, 18, 20, 22, 24, 26, 28 which are defined and specific terms so it will be represented by writing it in curly brackets

i.e. S ∈ { 14, 16, 18, 20, 22, 24, 26, 28}

Final answer,  the set will be S ∈ { 14, 16, 18, 20, 22, 24, 26, 28}

The final amount when $10,000 is invested for 3 years at 3% the interest is compounded continuously is  $10,942

What is compound interest ?

A compound interest rate is a rate of interest calculated on both the amount saved and the interest earned on it.

In the given question the expression to calculate amount is given as :

A = Pe^(rt)

where,

P = principle amount that is $10,000

r = rate of interest that is 3%

t = time period that is 3 years

Now, calculating Amount by substituting the above value in the formulae :

A = Pe^(rt)

A = 10000 e^(0.03 x 3)

A = 10000 e^(0.09)

A = 10000 x 1.0942

A = $10,942

Therefore, the final amount when $10,000 is invested for 3 years at 3% the interest is compounded continuously is $10,942

The solution of the given linear equation is y = 80.

According to the given question.

We have an equation.

-y + 13 = -67

Since, we have to solve the above linear equation in variable.

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, the solution of the linear equation in one variable -y + 13 = -67 is given by

-y + 13 = -67

⇒ - y = -67 -13 (subtractting 13 from both the sides)

⇒ -y = -80

⇒ y = 80

Hence, the solution of the given linear equation is y = 80.

The equation of to represent the two unknowns y and x is undefined hence it can be said not to be existing.

Equation of a straight line is the equation of the form

y = mx + c

y and x are the unknown variables

m is the slope

c is the intercept in the y axis

The equation given in the problem is a special type which is a vertical line

A vertical line has no intercept on the y axis hence c =0/ This reduces the equation of a straight line to

y = mx + c

at c = 0 we have:

y = mx + 0

y = mx

The slope of the vertical line is undefined. From first principles we have that slope is

m = change in y / change in x

for a line to be vertical the change in x is at the lowest absolute value and the smallest absolute number is zero. note negative number is not inclusive.

Therefore the slope at change in x = 0 represents a vertical line which is

m = change in y / change in x

m = change in y / 0

m = undefined

so y = undefined

check using calculator any number divided by zero gives error which is defined mathematically to be undefined,

We can conclude that the relationship between y and x from the graph is undefined.

Step-by-step explanation:

15 cents = 15/100 = $0.15

85 cents = 85/100 = $0.85

p + n = 50                    Eq. 1

0.15p + 0.85n = 18       Eq. 2

p = number of pencils

n = number of notebooks

From Eq. 1

p = 50 - n               Eq. 3

Replacing Eq. 3 in Eq. 2:

0.15(50-n) + 0.85n = 18

(0.15*50 + 0.15*-n) + 0.85n = 18

(7.5 - 0.15n) + 0.85n = 18

7.5 + 0.7n = 18

0.7n = 18 - 7.5

0.7n = 10.5

n = 10.5 / 0.7

n = 15

From Eq. 3:

p = 50 - n

p = 50 - 15

p = 35

Answer:

r=2

Step-by-step explanation:

To find the slope, we take the difference in the y values over the difference in the x values

m = ( y2-y1)/(x2-x1)

2 = ( 9-3)/ (5-r)

2 = (6)/(5-r)

Multiply each side by (5-r)

2 ( 5-r) = 6

Divide each side by 2

5-r = 6/2

5-r = 3

Subtract 5 from each side

5-r-5 = 3-5

-r = -2

r = 2

Answer:

r = 2

Step-by-step explanation:

To solve this problem, we have to use the following formula for slope:

[tex]\boxed{m= \frac{y_2 - y_1}{x_2 - x_1}}[/tex],

where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are the coordinates of two points.

We are given the coordinates [tex](r, 3)[/tex] and [tex](5, 9)[/tex], and told that [tex]m = 2[/tex]. To find the value of r, we have to substitute the given values into the formula and then solve for r :

[tex]2 = \frac{9 - 3}{5-r}[/tex]

⇒ [tex]2 = \frac{6}{5-r}[/tex]

⇒ [tex]2\times (5-r) = \frac{6}{5-r} \times (5 - r)[/tex]         [Multiplying both sides by (5 - r)

⇒ [tex]2(5-r) = 6[/tex]

⇒ [tex]\frac{2}{2}(5-r) = \frac{6}{2}[/tex]                                [Dividing both sides by 2]

⇒ [tex]5- r = 3[/tex]

⇒ [tex]5 - r - 5 = 3 - 5[/tex]                         [Subtracting 5 from both sides]

⇒ [tex]-r = -2[/tex]

⇒ [tex]\frac{-r}{-1}= \frac{-2}{-1}[/tex]                                       [Dividing both sides by -1]

The given pattern 5/7, 8/7, 11/7, 2, ....... is in the form of the arithmetic progression AP. The next 3 terms are  17/7, 20/7, 23/7.

An arithmetic progression is a sequence whose terms continue to increase and otherwise decrease by a constant number. The common difference is the set amount through which they either increase or decrease.

The following arithmetic progression formulas are frequently utilized to solve various AP problems for the initial term 'a' of an AP and the common difference 'd'-

Now, as per the stated question;

The AP given as; 5/7, 8/7, 11/7, 2, ...........

The series consists of four given terms.

Consider the initial term be 'a₁' = 5/7.

Then, the second term be 'a₂' = 8/7.

And, the third term be 'a₃' = 11/7.

And, the fourth term is 'a₄' = 2.

The AP have the same common difference. so,

d = a₃ - a₂

Substitute the values.

d = 11/7 - 8/7

d = 3/7

Thus, the common difference is 3/7.

or d = a₄ - a₃ (Put the values)

d = 2 - 11/7

d = 3/7

As, a₃ - a₂ = a₄ - a₃

Thus, we can conclude that the given sequence is in AP.

The fifth term will be; a₅ = a₄ + d = 2 + 3/7

a₅ = 17/7

Now, the 6th term will be; a₆ = a₅ + d = 17/7 + 3/7

a₆ = 20/7

Similarly, the 7th term will be; a₇ = a₆ + d = 20/7 + 3/7

a₇ = 23/7

Therefore, it can be said that the given sequence is in AP next three terms be 17/7, 20/7, 23/7.

The probability of getting a number greater than 1 is 5/6

What is the formula of Probability?

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.

Probability of event happen P(E) = Number of favourable outcomes / Total number of outcomes.

The possible outcomes when a die thrown is {1, 2, 3, 4, 5, 6}. Therefore, the number of possible outcomes of a die is 6.

Now, the numbers greater than 1 between 1 to 6 are P{2, 3, 4, 5, 6} then the number of favourable outcome is 5.

The length of the unknown leg is 8 yd in the given right triangle.

The Pythagoras theorem states that a right-angled triangle's hypotenuse square (90 degrees) equals the sum of the squares of its other two sides.

Let the three legs of the right triangle be a, b and c where a is the altitude, b is the base and c is hypotenuse of the given right angled triangle.

Here, a = [tex]\sqrt{23}[/tex] yd, b = ? and c = [tex]\sqrt{87}[/tex]

According to the Pythagoras theorem,

Hypotenuse² = Base² + Altitude²

c² = b² + a²

[tex](\sqrt{87})^{2}[/tex] = b² + [tex](\sqrt{23})^{2}[/tex]

87 = b² + 23

Subtracting 23 from both sides of the equation.

87 - 23 = b²

b² = 64

Taking square root of the both sides.

b = ± 8

Since the value of length can't be negative so the value of b = - 8 is rejected.

Therefore, the value of b = 8 yd.

As we have calculated above, the length of the unknown leg is 8 yd.
