A leasing agreement is for 5 years. A sum of £10,000 must be paid at the beginning of the first year, to be followed by four equal payments of £x at the beginning of years two, three, four and five. At a discount rate of 8 per cent, the present value of the four equal payments is £26,496. Compute the total amount to be paid during the lease period.

Answers

The total amount paid during the lease period is £45,665.64.

To find the total amount paid during the lease period, we need to add the initial payment of £10,000 to the present value of the four equal payments, which can be calculated using the present value formula:

PV = FV / (1 + r)^n

Where PV is the present value, FV is the future value, r is the discount rate, and n is the number of periods. In this case, the present value of the four equal payments is £26,496, the discount rate is 8%, and the number of periods is 4. We can solve for the future value by rearranging the formula:

FV = PV × (1 + r)^n

Plugging in the given values, we get:

FV = £26,496 × (1 + 0.08)^4

FV = £26,496 × 1.34

FV = £35,664.64

This is the total future value of the four payments. To find the total amount paid during the lease period, we need to add this to the initial payment of £10,000. Therefore, the total amount paid during the lease period is:

£35,664.64 + £10,000 = £45,665.64

Therefore the total amount paid during the lease period is £45,665.64.

If a matrix equation [math]Ax=b[/math] has one unique solution, does that imply the columns of A are linearly independent?

Answers

The matrix equation Ax=b with one unique solution says that column A is linearly independent.

Two vectors are linearly dependent if at least one of them can be expressed as a linear combination of the others. If no vector can be expressed as a linear combination of the others, then two or more vectors are said to be linearly independent.

Given the matrix equation is Ax=b. And this equation has one unique solution. Then, let us assume this unique solution is x₁.  Let the column values of A be A₁, A₂, A₃, .... Aₙ.

If there is only one solution to the equation Ax = b for all b, then assume b = 0 and come to the conclusion that there is only one solution to the equation Ax = 0 as well. Consequently, the only solution is straightforward, and the columns of A are linearly independent.

When the matrices A and B commute, or when they fulfill AB=BA, this is a significant exception.

What is matrix?


A matrix is a rectangular array or table of numbers, symbols, or formulae used to represent mathematical objects or qualities of such things. It is often arranged in rows and columns. For instance, a matrix contains two rows and three columns. a group of integers organized in a rectangular array in rows and columns. Matrix elements or entries refer to numbers. In several disciplines of engineering, physics, economics, statistics, and mathematics, matrices have a wide range of applications.

The eigenvalues and eigenvectors of the sum of two matrices are typically not the same as the sums of the eigenvalues and eigenvectors of the individual matrices. In actuality, there is no way to separate the eigenvalues of A and B from one another.

When a vector v is an eigenvector of both A and B, it is also an eigenvector of A+B, with an eigenvalue equal to the sum of its eigenvalues for A and B, respectively. There is, however, no reason to anticipate that two matrices will share an eigenvector in general. There is no method to create an eigenvector of A+B from two random eigenvectors of A and B alone.

When the matrices A and B commute, or when they fulfill AB=BA, this is a significant exception. In this situation, their invariant spaces coincide, and if both of them are diagonalizable, they are concurrently diagonalizable, which means that their eigenvectors do as well. As was already noted, in this specific instance, the eigenvectors of A+B are likewise the same.

Prove that if a ≡ b mod m and c ≡ d mod m, then ac ≡ bd mod m. [duplicate]

Answers

The four integers say a,b,c and d. If a and b are congruent to moulo m and c ,d are congruent to modulo m then ac and bd are must be congruent to modulo m .

What is congruent modulo ?

Two integers a and b are "congruent modulo n" if their difference is a multiple of n or in other words we say n/(b-a) . For example, 17 and 5 are congruent modulo 3 because 17 - 5 = 12 = 4×3

We have, a ≡ b mod m => m/(a - b)

and c ≡ d mod m => m/(c-d)

Now, a + c - b - d = (a-b) + (c-d)

because, m/( a - b) and m/(c-d)

=> m/( a-b+ c-d )

=> m/(a+c)-(b+d)

=> a+c ≡ b+d mod m

We have to prove that ac ≡ bd mod m.

ac - bd = c(a-b) + b(c- d)

Now, as we see, m/(a-b) => m/c(a-b)

and m/(c-d) => m/b(c-d)

=> m/(c(a-b) + b(c-d))

=> m/(ac - bc + bc - bd)

=> m/(ac - bd)

=> ac ≡ bd mod m

Hence proved.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (0, 4) and (8, 0).

Now,

Since, The equation of line passes through the points (0, 4) and (8, 0)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (0 - 4) / (8 - 0)

m = - 4 / 8

m = -1/2

We know that, The slopes of parallel lines are equal.

Thus, The equation of line with slope -1/2 is,

⇒ y - 4 = -1/2 (x - 0)

⇒ y - 4 = -1/2x

⇒ y = -1/2x + 4

Therefore, The equation of line passes through the points (0, 4) and

Given is that a room three times as long as it is broad and its height is 4.6 m. The cost of carpeting its floor at Rs. 240 per square meter be  the cost of painting the 4 walls at Rs. 24 per sq. m.​

Assume that the breadth to be equivalent to [x] meters. Then its length will be [3x] meters.

Area of floor = {3x} x {x} = 3x² sq. m.​

The cost of carpeting the floor = Rs. 240 per sq. m.

For 1 sq. m., the cost is 240 sq. m.

For {3x² sq. m}, the cost will be -

C{f} = 240 x 3x² = 720x²

C{f} = 720x²

The total area of the 4 walls = 4 × (3x) × 4.6 = 55.2x sq. m.

The cost of carpeting the walls = Rs. 24 per sq. m.

For {55.2x sq. m}, the cost will be -

C{w} = 24 x 55.2x = 1324.8x

C{w} = 1324.8x

The total cost of painting and carpeting -

C = C{w} + C{f} = 720x² + 1324.8x

C = ₹(720x² + 1324.8x)

(b) Which critical values make sense in this particular problem? (Enter your answers as a comma-separated list.)
(c) For which values of t, for 0 ≤ t ≤ 10, is y increasing? (Enter your answer using interval notation.)

Answers

The critical values for the function are t = 6 , -5.667 where t = 6 makes sense . At t = 6 , y is increasing

According to the question,

After t hours of production, a plant produces an average of y units per hour, according to analysis of its daily output is

y = 102t + 0.5t² - t³ , 0 ≤ t ≤ 10

(a) To calculate critical values for the given function

We have to differentiate it w.r.t time and then have to put y'=0

=> y = 102t + 0.5t² - t³

Derivating w.r.t time

=> y' = 102 + t - 3t²

Equating to zero,

=>  102 + t - 3t² = 0

Solving quadratic equation,

=> t = 6 , -5.667 are critical values

(b) t = 6 makes sense in particular problem because time cannot be negative.

(c) To check increasing value

Derivate y' w.r.t time again

=> y" = 1 - 6t

Putting critical value,

At t = 6

y" < 0 , Therefore at t = 6 function is increasing

Hence , For t = 6 y is increasing

Answers

Correct option will be (C) In the short run, firms may incur economic losses or earn economic profits, but in the long run they earn normal profits.

The short run is a concept that states that, within a certain period in the future, at least one input is fixed while others are variable. In economics, it expresses the idea that an economy behaves differently depending on the length of time it has to react to certain stimuli. The short run does not refer to a specific duration of time but rather is unique to the firm, industry or economic variable being studied.

Debs and Jamie share sweetss in the ratio 3:7. Debs has 20 less sweets than Jamie. How many sweets are there in total? Show all workings please

Answers

Using ratios we know that the total number of sweet Debs and Jamie has is 50.

What is the ratio?

A ratio in mathematics demonstrates how many times one number is present in another.

For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.

Two quantities are compared to form a ratio.

An equality of two ratios is a proportion.

How to format a ratio Analyze the ratio to see whether it is part to part or part to whole.

Calculate the whole and the pieces as necessary.

So, we have a ratio of 3:7.

Debs has 20 fewer sweets than Jamie.

Let, Jamie have x sweets and Debs has x - 20.

Now, we get the equation:

3/x - 20 = 7/x

Now, solve as follows:

3/x - 20 = 7/x

3x = 7(x - 20)

3x - 7x - 140

7x - 3x = 140

4x = 140

x = 140/4

x = 35

x - 20 = 35 - 20 = 15

Total: 35 + 15 = 50

Therefore, using ratios we know that the total number of sweet Debs and Jamie has is 50.

Find integers a, b that do not have a greatest common divisor. Prove that the pair of numbers that you found are the only pair of integers that do not have a gcd.

Answers

C(n) = min(αn, βn) then gcd(0,b) = p(1)^(c1)∙p(2)^(c2)..................p(n)^(cn). So for all other a, b have gcd exist.

The integer a=0 and b=0 does not have any greatest common divisor.

Suppose n = gcd(0,r)

Then 12|0 and 12|0 also n is the greatest divides both (a=0), (b=0).

But n+1|0, n+1|0 as (n+1)*0 = 0 which is a contradiction to n = gcd(0, r).

Hence, gcd(0, r) does not exist.

But if a≠0 or b≠0.

It has a unique prime factorization that is;

a= p(1)^(α1)∙p(2)^(α2)∙p(3)^(α3)......................p(n)^(αn),

b= p(1)^(β1)∙p(2)^(β2)∙p(3)^(β3)......................p(n)^(βn).

Let C(n) = min(αn, βn) then gcd(0,b) = p(1)^(c1)∙p(2)^(c2)..................p(n)^(cn).

So for all other a, b have gcd exist.

The missing value of x = 6

What is value ?

Value in mathematics can refer to a number of closely related ideas. A mathematical value can generally be any specific mathematical object. This is most frequently a number in elementary mathematics, such as a real number like or an integer like 42.

Depending on where it is in the number, each digit has a different value, which is referred to as value. We figure it out by multiplying the digit's place value by its face value. Place value plus face value equals value.

Values are the benchmarks or ideals by which we judge the acts, traits, possessions, or circumstances of others. Values that are embraced by many include those of beauty, honesty, justice, peace, and charity.

4200 / x = 700

If the fraction is defined, the denominator cannot equal 0:

x ≠ 0

Append the inequality as the domain:

x ≠ 0

Multiply both sides of the equation by the common denominator:

400x / x = 700 x

Reduce the fractions:

4200 = 700 x

Swap the sides:

700 x = 4200

Divide both sides of the equation by the coefficient of variable:

x = 4200 / 700

Cross out the common factor:

x = 6

Convert 284 °F to Celsius

Answers

Hi, To convert a temperature from degrees Fahrenheit to degrees Celsius, you can use the following formula:

C = (F - 32) / 1.8

Substituting the value of F and solving for C, we find that:

C = (284 - 32) / 1.8

= 252 / 1.8

= 140

Therefore, 284 °F is equivalent to 140 °C.

Suppose 6 adults produce 189.6 lb of garbage in one week. At this rate, how many pounds will 40 adults produce in one week?

Answers

Answer: 1264 pounds of garbage in one week

Step-by-step explanation: This problem is a unit rate problem, so, we need to find the unit rate of this word problem. To do that, you would do the amount of garbage produced (189.6) divided by the number of adults (6), which equals 31.6. So, the unit rate is 31.6 pounds of garbage for one adult. Then, you need to do 31.6 times 40 (for the number of adults) which equals 1264.
