The summation ∑₁¹²⁴(29a₁ - 13b₁)  = -30

How to find the given summation?

Suppose that ∑₁¹²⁴a₁ = -10 and  ∑₁¹²⁴b₁ = -20. We desire to compute the following ∑₁¹²⁴(29a₁ - 13b₁), we proceed as follows.

So, the summation ∑₁¹²⁴(29a₁ - 13b₁)

Expanding the brackets, we have that

∑₁¹²⁴(29a₁ - 13b₁) = ∑₁¹²⁴29a₁ -  ∑₁¹²⁴13b₁)

= 29∑₁¹²⁴a₁ -  13∑₁¹²⁴b₁

Given that ∑₁¹²⁴a₁ = -10 and  ∑₁¹²⁴b₁ = -20.

So, substituting the values of the variables into the equation, we have that

∑₁¹²⁴(29a₁ - 13b₁) = 29∑₁¹²⁴a₁ -  13∑₁¹²⁴b₁

= 29(-10) - 13(-20)

= -290 + 260

= -30

So, ∑₁¹²⁴(29a₁ - 13b₁)  = -30

A rectangle is drawn so the width is 47 inches longer than the heightIf the rectangle's diagonal measurement is 65 inches , find the height. Give your answer rounded to 1 decimal place.

Answers

The height of the rectangle is approximately 15.5 inches.

Let's call the height of the rectangle "h". We know that the width is 47 inches longer than the height, so the width can be expressed as "h + 47".

We can use the Pythagorean theorem to solve for the height. The Pythagorean theorem states that for a right triangle with legs of length "a" and "b" and hypotenuse of length "c", a^2 + b^2 = c^2.

In this case, we can consider the rectangle to be a right triangle, with the height as one leg, the width as the other leg, and the diagonal as the hypotenuse. So we can write:

h^2 + (h + 47)^2 = 65^2

Simplifying this equation gives:

2h^2 + 94h - 1476 = 0

We can solve for "h" using the quadratic formula:

h = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 2, b = 94, and c = -1476. Plugging these values into the quadratic formula gives:

h = (-94 ± sqrt(94^2 - 4(2)(-1476))) / 4

Simplifying this expression gives:

h = (-94 ± sqrt(10084)) / 4

h = (-94 ± 100.42) / 4

h = -48.6 or 15.42

Since the height of the rectangle cannot be negative, we can discard the negative solution. Therefore, the height of the rectangle is approximately 15.5 inches.

>Suppose Big D, Inc. just paid a dividend of $.50. It is expected to increase its dividend by 2% per year.
If the market requires a return of 15% on assets of this risk, how much should the stock be selling for?

Answers

If the market requires a return of 15% on assets of this risk, the stock should be selling for $3.92.

How much should the stock be sold for?

We can calculate the stock price using the dividend discount model with the following formula: "Stock Price = Dividend / (Required Rate of Return - Dividend Growth Rate)".

Data:

Dividend =  $0.50

Increase its dividend by 2% per year.

The next dividend (D1) can be calculated as:

D1 = D0 x (1 + Dividend Growth Rate)

D1 = $0.50 x (1 + 0.02)

D1 = $0.51

Using these values, we can calculate the stock price as follows:

= $0.51 / (0.15 - 0.02)

= $0.51 / 0.13

= $3.92.

Breanna and Qasim plan to send their daughter to university. To pay for this they will contribute 8 equal yearly payments to an account bearing interest at the APR of 4%, compounded annually. Five years after their last contribution, they will begin the first of five, yearly, withdrawals of $51,100 to pay the university's bills. How large must their yearly contributions be?

Answers

Breanna and Qasim must contribute $22,583.39 per year for eight years to have enough money to pay for their daughter's university education.

To determine the yearly contribution required for Breanna and Qasim, we need to use the present value formula for an annuity.

The formula is:

PV = C * ((1 - (1 + r)⁻ⁿ) / r)

Where PV is the present value of the annuity, C is the annual contribution, r is the annual interest rate, and n is the number of years.

First, we need to calculate the present value of the contributions that Breanna and Qasim make for the first eight years. We can use the formula:

PV = C * ((1 - (1 + r)⁻ⁿ) / r)

Where C is the annual contribution, r is the annual interest rate, n is the number of years, and PV is the present value of the contributions.

We know that the annual contribution is the same for each of the eight years, so we can simplify the formula to:

PV = C * (((1 - (1 + r)⁻ⁿ) / r))

The present value of the contributions is equal to the future value of the withdrawals five years after the last contribution. We can use the future value formula for an annuity to calculate this:

FV = R * ((1 + r)ⁿ - 1) / r

Where FV is the future value, R is the annual withdrawal, r is the annual interest rate, and n is the number of years.

We know that the future value of the withdrawals is $51,100 per year, the interest rate is 4%, and the number of years is 5.

FV = 51,100 * ((1 + 0.04)⁵ - 1) / 0.04 = $246,387.19

This is the present value of the contributions that Breanna and Qasim make over the first eight years. We can now solve for the annual contribution required using the present value formula:

PV = C * (((1 - (1 + r)⁻ⁿ) / r))

$246,387.19 = C * (((1 - (1 + 0.04)⁻⁸) / 0.04))

C = $22,583.39

Las llantas de la bicicleta de Julián miden 45 cm de diámetro y la distancia de su casa a la escuela es de 877 m cuántas vueltas aproximadamente deben de dar las llantas de la bicicleta de Julián para ir de su casa a la escuela

Answers

The tires of Julián's bicycle must take 620 turns to go from his house to school.

The circumference of the tire can be calculated using the formula C = πd, where d is the diameter of the tire.

C = πd = π(45cm) ≈ 141.37cm

To find out how many turns the tires must take, we need to divide the total distance by the distance covered by one revolution of the tire:

Number of turns = Distance / Circumference

Number of turns = 877m / (141.37cm/100cm/1m)

Number of turns ≈ 620.09

Answers

Answer:   [1/5x-4+2y]+[2/5x+5-4y] simplifies to 3/5x - 2y + 1.

Step-by-step explanation:

To simplify the given expression, we need to combine like terms.

The like terms are the ones with the same variable parts.

Let's first simplify the expression inside the brackets separately:

[1/5x-4+2y] = 1/5x + 2y - 4

[2/5x+5-4y] = 2/5x - 4y + 5

Now, we can combine the simplified expressions:

[1/5x + 2y - 4] + [2/5x - 4y + 5]

= 1/5x + 2y - 4 + 2/5x - 4y + 5

= (1/5 + 2/5)x + (2y - 4y) - 4 + 5

= 3/5x - 2y + 1

Therefore, [1/5x-4+2y]+[2/5x+5-4y] simplifies to 3/5x - 2y + 1.

A pair of shoes usually sells for $67. If the shoes are 20% off, and sales tax is 5%, what is the total price of the shoes, including tax?

Answers

Answer:

If the shoes are 20% off, then the sale price of the shoes will be:

67 - 0.20 * 67 = 67 - 13.40 = 53.60

So the sale price of the shoes is $53.60.

If the sales tax is 5%, then the tax on the shoes will be:

0.05 * 53.60 = 2.68

So the tax on the shoes is $2.68.

To find the total price of the shoes including tax, we need to add the sale price of the shoes and the tax:

53.60 + 2.68 = 56.28

Therefore, the total price of the shoes, including tax, is $56.28.

Answer:

$56.28

Step-by-step explanation:

1. Find the shoes' sale price.

The shoes are 20% off. We will find the new price by first finding 20% of $67.

An easy way to do it:

10% of 67 = 6.7
20% of 67 = 13.4

to double the percentage of the first equation, double the answer.

Now that we know 20% of 67 we can take away 20% from it:

67 - 13.4 =53.6

Money uses 2 decimal points so we will add a 0 at the end of the result.

The price of the shoes with only the sale is $53.60.

2. Add sales tax

First find out 5% of $53.60.

An easy way to do it:

10% of 53.60 = 5.360

5% of 53.60 = 2.68

to half the percentage of the first equation, half the answer.

Now that we know the price of the tax we can add it to our shoe price. With the sale the shoe costs $53.60 and we will add our tax:

53.60 + 2.68 = 56.28

Add your units:

Concept 1. What a Local minimum is

Concept 2. Where a local minimum is at

Brief side-discussion:  a Local minimum  vs  Absolute or Global minimum

A local minimum is the height of any "low" point on a continuous section of the function where all of the points "near" it are higher.

In contrast, an Absolute minimum (sometimes called a "global minimum"), is the lowest height the function ever reaches.

Concept 1. What a Local minimum is

This problem is asking about local minimums, of which there are two:

the height of the point in the trough on the leftthe height of the point in the trough on the right

"The Local minimum value" itself IS the height of the point (the "y"-value).

The point on the left has coordinates (-3,1), and the point on the right has coordinates (4,-2).

So, the local minima are 1 and -2

Concept 2. Where a local minimum is at

The minima are different from "The values AT which the function has a local minimum" which is the input (or, "x"-value) that will produce that output when put into the function.

So, the values at which the function f has a local minimum are -3 and 4

m∠BJA = m∠DFE = 52° m∠ABJ = m∠EDF = 65°

Therefore, m∠ABJ = 65°.

Interior angles in a triangle sum to 180°. Therefore:

⇒ m∠JAB + m∠BJA + m∠ABJ = 180°

⇒ m∠JAB + 52° + 65° = 180°

⇒ m∠JAB + 117° = 180°

⇒ m∠JAB = 63°

As m∠JAB = m∠FED, then m∠FED = 63°.

The function that is most likely increase exponentially is f(x). Because it eventually exceeds g(x)

To determine which function is most likely increasing exponentially, we need to compare the rate at which the two functions are increasing.

Looking at the table, we can see that as x increases, f(x) increases at a faster rate than g(x). In fact, f(x) eventually exceeds g(x) for x values greater than or equal to 5. This suggests that f(x) is increasing at an exponential rate.

On the other hand, g(x) is increasing at a much slower rate than f(x). Although g(x) is also increasing, it does not appear to be increasing exponentially. In fact, g(x) will never exceed f(x), because f(x) grows at a faster rate.

Therefore, the function that is most likely increase exponentially is f(x).

A coin is flipped 10 times and the sequence of heads and tails recorded. In how many ways can a sequence consist of exactly 3 heads and the rest tails?

Answers

We can use the binomial probability formula to solve this problem. The formula is:

P(X=k) = (n choose k) * p^k * (1-p)^(n-k)

where:
- P(X=k) is the probability of getting exactly k successes
- n is the total number of trials
- k is the number of successes
- p is the probability of success in one trial
- (n choose k) is the binomial coefficient, which represents the number of ways to choose k items from a set of n items

In this problem, we want to find the number of ways to get exactly 3 heads in 10 coin flips. The probability of getting a head in one coin flip is 1/2, so p=1/2. The number of trials is n=10, and the number of successes we want is k=3. Plugging these values into the formula, we get:

P(X=3) = (10 choose 3) * (1/2)^3 * (1/2)^(10-3)
= (10! / (3! * 7!)) * (1/2)^10
= 120 * (1/2)^10
= 0.1171875

Therefore, there are 0.1171875 ways to get exactly 3 heads in 10 coin flips. Since we can't have a fraction of a sequence, we can say that there is only 1 way to get exactly 3 heads in 10 coin flips (since there is only one sequence that satisfies this condition).

there are 120 different ways a sequence of 10 coin flips can consist of exactly 3 heads and the rest tails.

To solve this problem, we can use the formula for combinations. The number of ways to choose k items from a set of n items is given by the formula n choose k, which is written as C(n,k) or sometimes as nCk.

In this case, we want to choose 3 heads from a set of 10 coin flips. The number of ways to do this is C(10,3) = 120.

Once we have chosen the 3 heads, the remaining 7 flips must all be tails. There is only one way to arrange 7 tails, since they are all the same.

Therefore, the total number of sequences that consist of exactly 3 heads and the rest tails is 120.
