a)Find x and y

BCD=ACB+ACD

180°=ACB+150°

ACB=180°-150°

ACB=30°

since triangle ABC is an isosceles triangle

therefore, AB=BC

BAC=ACB

y=ACB=30°

ACB+ABC+BAC=180°

ABC+2BAC=180°

ABC+2*30°=180°

ABC=180°-60°

ABC=120°

Hey there!

Each person would mostly get approximately $10.35 because you simply DIVIDE 31.05 from 3 & 10.35 * 3 gives you $31.05

Here’s an equation you can set it up as

• 3p = number of people

• 31.05 could be the one the one we’re dividing with p

• So your equation will most likely look like:

3p = 31.05

“3p = 31.05”

• DIVIDE both of your sides by 3

3p/3 = 31.05/3

• Cancel out

3p/3 because that gives you 1

• Keep

31.05/ 3 because that helps us solve what we give to the number of people

p = 31.05 / 3

➡️ 31.05 / 3 = 10.35

Thus, each person will get: 10.35

So that further a do: your answer is “10.35”☑️

Good luck on your assignment and enjoy your day!

Answer:

82

Step-by-step explanation:

The formula is:

(n*26) - 204

Equation is (n * a) + x

n = 10 => 10a + x = 56 => x = 56-10a

n = 12 => 12a + x = 108 => x = 108 - 12a

56-10a = 108-12a

2a = 52

a = 26

x = 56 - 10a = 56 - (10*26) = -204

Equation = (26 * n) - 204

n = 11 => (26 *11) - 204 = 286 - 204 = 82

The 11th term will be equal to 82

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

The formula is:

Equation is (n * a) + x

(n*26) - 204

n = 10 => 10a + x = 56 => x = 56-10a

n = 12 => 12a + x = 108 => x = 108 - 12a

56-10a = 108-12a

2a = 52

a = 26

x = 56 - 10a = 56 - (10*26) = -204

Equation = (26 * n) - 204

n = 11 => (26 *11) - 204 = 286 - 204 = 82

Hence the 11th term will be equal to 82.

Answer:

Step-by-step explanation:

P: the principal, amount invested

A: the new balance

t: the time

r: the rate, (in decimal form)

n: the number of times it is compounded.

Ex2:Suppose that $5000 is deposited in a saving account at the rate of 6% per year. Find the total amount on deposit at the end of 4 years if the interest is:

P =$5000, r = 6% , t = 4 years

a) simple : A = P(1+rt)

A = 5000(1+(0.06)(4)) = 5000(1.24) = $6200

b) compounded annually, n = 1:

A = 5000(1 + 0.06/1)(1)(4) = 5000(1.06)(4) = $6312.38

c) compounded semiannually, n =2:

A = 5000(1 + 0.06/2)(2)(4) = 5000(1.03)(8) = $6333.85

d) compounded quarterly, n = 4:

A = 5000(1 + 0.06/4)(4)(4) = 5000(1.015)(16) = $6344.93

e) compounded monthly, n =12:

A = 5000(1 + 0.06/12)(12)(4) = 5000(1.005)(48) = $6352.44

f) compounded daily, n =365:

A = 5000(1 + 0.06/365)(365)(4) = 5000(1.00016)(1460) = $6356.12

Answer:

Step-by-step explanation:

Answer:

t ≥ 29

Step-by-step explanation:

Given the following :

Company A:

Cost of plan = $29.99

Night and weekend minutes = unlimited

Company B :

Cost of plan = $19.99

Night and weekend = $0.35 per minute

Let number of night and weekend minute = t

For what number of night and weekend minutes does the second company's plan cost more than the first company's plan

Company A > Company B

(19.99 + 0.35*t) > 29.99

19.99 + 0.35t > 29.99

0.35t > 29.99 - 19.99

0.35t > 10

t > 10/0.35

t > 28.57

28.57 to the nearest whole number = 29

t ≥ 29

The equation of a line perpendicular to 2x-3y=6 and passes through the point (6,-1) is y=2/3x-5.

The given line 2x-3y=6 has a slope of m=2/3.

A line perpendicular to this line will have a slope that is the negative reciprocal of this slope. Therefore, the slope of the line perpendicular to 2x-3y=6 is -3/2.

Using the point-slope formula to find the equation of the line:y-y1 = m(x-x1).

Substituting in the point (6,-1) and the slope of -3/2:y-(-1) = -3/2(x-6)y+1 = -3/2x + 9y = -3/2x + 8.

The equation of a line perpendicular to 2x-3y=6 and passes through the point (6,-1) is y=2/3x-5.

In question 1, the recursive formula for the balance of Mohamed's credit card debt each month can be written as Bₙ = 1.02Bₙ₋₁ - 300, where Bₙ represents the balance in the nth month.

In question 2, (i) The second term in the expansion of (y-2x)³ is option B: -8y³x.

(ii) Row 7 of Pascal's Triangle is option B: 1, 5, 10, 10, 5, 1.

(iii) Expanding (2x³ + 1)³ completely yields 8x⁹ + 12x⁶ + 6x³ + 1.

In question 3, To prove the statement that the sum of the first n odd numbers is equal to the nth square (1+3+5+7+...+(2n-1) = n²) by mathematical induction, the induction assumption is option A: The statement is true for n=k: 1 + 3 + 5 + 7 + ... + (2k-1) = k².

In question 4, the probability distribution for the random variable X, representing the work atmosphere scores, can be constructed using the given frequency distribution.

In question 1(i), the recursive formula Bₙ = 1.02Bₙ₋₁ - 300 represents the balance of Mohamed's credit card debt each month. The balance increases by 2% each month due to interest and decreases by the monthly payment of AED 300.

In question 1(ii), to find the first three iterates of the function f(x) = 5x + 4 starting with x₀ = 2, we substitute the value of x₀ into the function and then repeatedly apply the function to obtain x₁, x₂, and x₃.

In question 2, the answers are obtained as follows:

(i) To find the second term in the expansion of (y-2x)³, we use the binomial expansion formula (a-b)³ = a³ - 3a²b + 3ab² - b³. In this case, a = y and b = 2x. Using the formula, the second term is -3a²b = -3(y)²(2x) = -3y²(2x) = -6xy². However, in the given options, the term is in the form -8y³x. To match this form, we can rewrite -6xy² as -8y³x. Therefore, the second term is -8y³x, which corresponds to option B.

(ii) Pascal's Triangle is a triangular arrangement of numbers where each number is the sum of the two numbers above it. Row 7 of Pascal's Triangle is 1, 6, 15, 20, 15, 6, 1. However, none of the options matches this row. Thus, the given options are incorrect, and the correct row 7 of Pascal's Triangle is not provided.

(iii) To expand (2x³ + 1)³ completely, we use the binomial expansion formula (a + b)³ = a³ + 3a²b + 3ab² + b³. In this case, a = 2x³ and b = 1. Applying the formula, we obtain (2x³ + 1)³ = (2x³)³ + 3(2x³)²(1) + 3(2x³)(1)² + (1)³. Simplifying this expression gives 8x⁹ + 12x⁶ + 6x³ + 1.

Therefore, the second term in the expansion of (y-2x)³ is -8y³x, the correct row 7 of Pascal's Triangle is not provided, and the expansion of (2x³ + 1)³ is 8x⁹ + 12x⁶ + 6x³ + 1.

In question 3, To prove the given statement using mathematical induction, we need to follow the steps of induction: base case and induction step.

The base case is when n = 1. We need to show that the statement is true for n = 1. Evaluating the left-hand side (LHS) and right-hand side (RHS) of the equation, we have 1 = 1², which is true.

Next, we assume that the statement is true for some value k, which is the induction assumption. In this case, the assumption is that 1 + 3 + 5 + 7 + ... + (2k-1) = k².

Now, we need to prove that the statement holds for n = k+1. This is the induction step. We add (2k+1) to both sides of the assumption and evaluate the LHS and RHS. The LHS becomes 1 + 3 + 5 + 7 + ... + (2k-1) + (2k+1), and the RHS becomes (k+1)².

By applying the induction assumption and simplifying the LHS, we can show that it is equal to (k+1)², proving the statement for n = k+1.

Therefore, option A: The statement is true for n=k: 1 + 3 + 5 + 7 + ... + (2k-1) = k² is the correct induction assumption for proving the sum of the first n odd numbers is equal to the nth square.

Regarding the second part, to prove that 7ⁿ - 4ⁿ is divisible by 3, we can use mathematical induction. By verifying the base case (n = 1) and assuming the statement is true for n = k, we can prove that it holds for n = k+1.

In question 4, to construct the probability distribution for the random variable X, we use the frequency distribution to determine the probabilities associated with each score. The expected value of the distribution can be calculated by multiplying each score by its corresponding probability and summing the results.

By understanding the concepts and applying the appropriate formulas and techniques, the solutions to these questions can be obtained.

The length of minor arc CD is [tex]\( \frac{5\pi}{3} \)[/tex] units.

1. Let's start by finding the measure of angles x and y. We know that the area of the circle is [tex]\(81\pi\)[/tex], and since the area of a circle is given by the formula [tex]\(A = \pi r^2\[/tex]), we can equate it to find the value of [tex]\(r\). So, \(81\pi = \pi r^2\).[/tex]

  Solving this equation, we get [tex]\(r^2 = 81\)[/tex], which gives us [tex]\(r = 9\)[/tex].

2. Since points A, B, C, and D are on the circle, we can consider the angles formed by the lines connecting these points to the center of the circle.

3. Let's assume that the measure of angle x is [tex]\(a\)[/tex] radians. As per the given information, the measure of angle y is [tex]\( \frac{5\pi}{9} \)[/tex] radians greater than angle x. So, the measure of angle y is [tex]\(a + \frac{5\pi}{9}\)[/tex] radians.

4. Since angles x and y are formed by lines from the center of the circle, the sum of their measures should be equal to [tex]\(2\pi\)[/tex] radians. So we can write the equation [tex]\(a + (a + \frac{5\pi}{9}) = 2\pi\).[/tex]

5. Simplifying the equation, we get [tex]\(2a + \frac{5\pi}{9} = 2\pi\).[/tex]

6. Solving for [tex]\(a\)[/tex], we find [tex]\(a = \frac{4\pi}{9}\).[/tex]

7. Now that we have the value of angle x, we can find the measure of angle z. Again, since the sum of angles formed by lines from the center of the circle is [tex]\(2\pi\)[/tex], we can write the equation [tex]\(a + (a + \frac{5\pi}{9}) + z = 2\pi\)[/tex].

8. Substituting the known values, we have [tex]\( \frac{4\pi}{9} + (\frac{4\pi}{9} + \frac{5\pi}{9}) + z = 2\pi\)[/tex].

9. Simplifying the equation, we get [tex]\( \frac{13\pi}{9} + z = 2\pi\)[/tex].

10. Solving for [tex]\(z\)[/tex], we find [tex]\(z = \frac{5\pi}{9}\)[/tex].

11. Angle z represents the measure of the central angle that corresponds to minor arc CD.

12. The length of a minor arc in a circle is given by the formula [tex]\(s = r\theta\)[/tex], where [tex]\(r\)[/tex] is the radius of the circle and [tex]\(\theta\)[/tex] is the central angle in radians.

13. Substituting the known values, we have [tex]\(s = 9 \cdot \frac{5\pi}{9} = \frac{5\pi}{3}\)[/tex].

14. Therefore, the length of minor arc CD is [tex]\( \frac{5\pi}{3} \)[/tex] units.

PV = FV/( 1 r) n

where, FV = unborn value = $ 7,000

r = periodic interest rate = 2.75

n = number of times = 8

Substituting the given values, we get

PV = $ 7,000/( 10.0275) 8PV = $ 5,634.34

Hence, the quantum that should be paid moment for the security is$ 5,634.34.

2) We're given that Alicia will save$ 6,000 at the end of each time until she's 65.

We need to calculate how important she'll have in her withdrawal account at age 65, given that the account earns6.5 per time.

To calculate the unborn value of her savings, we can use the following formula

FV = PMT *(( 1 r) n- 1)/ r

The Probability of all four boys being chosen is only 1.8%. This means that it would be highly unlikely to occur by chance alone.

In a classroom with some girls and some boys, four students are chosen at random to lead a class discussion. All of those chosen are boys. The probability of this happening would be highly unlikely to occur by chance alone.

In probability theory, the probability of an event is a measure of the possibility of the event occurring. It is expressed as a value between zero and one, with zero representing impossibility and one representing certainty.

The formula for calculating the probability of an event is the number of ways the event can occur divided by the total number of possible outcomes. In this case, the probability of four boys being chosen from a mixed group of boys and girls is calculated as follows:

The probability of the first boy being chosen is the number of boys divided by the total number of students. If there are 30 students in the class, 15 boys, and 15 girls, then the probability of the first boy being chosen is 15/30.

The probability of the second boy being chosen is the number of remaining boys divided by the total number of remaining students. After the first boy is chosen, there are 14 boys and 29 students left. Therefore, the probability of the second boy being chosen is 14/29.

The probability of the third boy being chosen is the number of remaining boys divided by the total number of remaining students. After the second boy is chosen, there are 13 boys and 28 students left. Therefore, the probability of the third boy being chosen is 13/28.

The probability of the fourth boy being chosen is the number of remaining boys divided by the total number of remaining students.

After the third boy is chosen, there are 12 boys and 27 students left.

Therefore, the probability of the fourth boy being chosen is 12/27.To find the probability of all four boys being chosen, we multiply the probabilities of each event together:15/30 * 14/29 * 13/28 * 12/27 = 0.018 or 1.8%

Therefore, the probability of all four boys being chosen is only 1.8%. This means that it would be highly unlikely to occur by chance alone.
