Answer:

Step-by-step explanation:

Given that $6000 is deposited into an account earning 5.9% compounded quarterly, you want the values of P, r, n used in the future-value formula, and you want the value after 9 years.

The problem statement tells you the values:

  amount deposited = P = 6000

  interest rate = r = 5.9% = 0.059

  compounding periods in a year = n = 4

Using these numbers in the formula, you find (with t=9) ...

  S(9) = 6000(1 +0.059/4)^(4·9) ≈ $10164.30

Answer:

24 sides

Step-by-step explanation:

The interior angles of a polygon add up to 180(n-2) degrees, where n is the number of sides the polygon has. This means that to find the number of sides a polygon has, we can set up the following equation:

180(n-2) = 4320

Solving for n, we get:

n = (4320 + 360) / 180 = 24

Therefore, the polygon has 24 sides.

By using properties of quadrilateral, it can be concluded that-

Square describes the quadrilateral STUV

What is a quadrilateral?

Quadrilateral is a two dimensional four sided figure.

Here the properties of quadrilateral STUV is

Pair of opposite sides are parallel

Diagonals are congruent.

In a parallelogram, the  pair of opposite sides are parallel but diagonals are not congruent

Triangle is not a  quadrilateral

In Rhombus, the  pair of opposite sides are parallel but the diagonals are not congruent

In square, the pair of opposite sides are parallel and the diagonals are congruent

In Trapezoid, one pair of opposite sides are parallel and one pair of opposite sides are non parallel.

So Square describes the quadrilateral STUV

Monica was wrong she will get less interest than Paul as Paul has invested a higher Principal amount than Monica.

What is simple interest?

Simple interest is based on the principal amount of a loan or the first deposit in a savings account.

                         [tex]A = P (1 + rt)\\\\A $ = final amount$\\P $ = initial principal balance$\\r $ = annual interest rate$\\t $ = time (in years)$[/tex]

Given that:

For Monica:

Principal (p) = $400

Rate (r) = 4.3% = 0.043

Year (t) = 1 year

Deposit Paul:

Principal = $500

Rate (r) = 4.2%  = 0.042

Year (t) = 1 year

Now calculate the interest amount for Monica and Paul, we get

For Monica:

             A = P(1 + rt)

             A = 400(1 + (0.043 × 1))

             A = 417.2

             A = $417.20

Now for Monica, Interest will be

           I = A - P

             = 417.20 - 400

           I = 17.20 dollars -----------(II)

For Paul:

             A = P(1 + rt)

             A = 500(1 + (0.042 × 1))

             A = 521

             A = $521 dollars

Now for Paul, Interest will be

           I = A - P

             = 521 - 500

           I = 21 dollars ---------------(II)

From (I) and (II), we can say that Paul will earn more interest than Monica.

Hence, Monica was wrong she will get less interest than Paul as Paul has invested a higher Principal amount than Monica.

The accumulated value of an investment of $4,000 at 5% compounded semiannually for 8 years is $5,938.02.

When you add the interest you have already earned back into your principal balance, you are earning compound interest, which increases your profits.

Compound interest, also known as interest on principal and interest, is the practise of adding interest to the principal amount of a loan or deposit.

Given:

Investment amount= $4000

Rate of Interest, R= 5%

Time= 8 years semiannually

So, r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P[tex](1 + r/n)^{nt[/tex]

A = 4,000.00[tex](1 + 0.05/2)^{(2)(8)[/tex]

The cost of one ft² of grass sod is $3 and the cost of one shrub is $10.

Let the cost of grass be g and the cost of shrubs be s.

Pranav spent $90 on 10 ft² of grass sod and 5 shrubs. Thus, the equation that portrays this is;

10g + 5s = 90   -----(1)

Paul spent $50 on 5 ft² of grass sod and 3 shrubs. Thus, the equation that portrays this is;

5g + 3s = 50   ------(2)

Multiply eq 2 by 2 to get;

10g + 6s = 100   -----(3)

Subtract eq 1 from eq 2 to get;

s = 10

Put 10 for s in eq 1 to get;

10g + 5(10) = 90

10g = 40

g = 4

Thus, we conclude that the cost of grass sod and shrubs are the values of s and g above.

If the regular box has dimensions l, w, and h, then the dimensions of the family value box would be 1.25l, 1.25w, and 1.25h. This means that the volume of the family value box would be 1.25 * 1.25 * 1.25 = 1.953125 times the volume of the regular box. Since the family value box is 25% larger in each dimension, its volume is nearly double the volume of the regular box.

The equation of a line is an equation that describes the line. It is given by y = mx + c where

Since the equation of a line is given by y = mx + c and we have the points from the table (-5, 2) and (0, 7)

Substituting these evalues into the equation, we have

y = mx + c

2 = m(-5) + c

2 = -5m + c  (1)

Also, the point (0,7),we have

y = mx + c

7 = m(0) + c

7 = 0 + c

c = 7

Substituting c = 7 into equation (1), we have that

The dimension of the eigenspace corresponding to an eigenvalue is the number of linearly independent eigenvectors associated with that eigenvalue

What is Eigen Value?

Eigenvalues are a unique set of scalar values connected to a set of linear equations that are most likely seen in matrix equations. The characteristic roots are another name for the eigenvectors. It is a non-zero vector that, after applying linear transformations, can only be altered by its scalar factor.

It is not possible to determine the eigenvalues, their multiplicities, and the dimensions of the corresponding eigenspaces of the matrix g without more information about the matrix itself.

In order to find the eigenvalues of a matrix, you need to determine the values of the variables in the matrix and then solve the characteristic equation, which is obtained by setting the determinant of the matrix equal to zero.

The eigenvalues are the roots of the characteristic equation, and the multiplicity of an eigenvalue is the number of times it appears as a root.

Answer:

Step-by-step explanation:

To calculate the original price of the sweater, we first need to determine the amount of the discount. Since the sweater was 40% off, the discount was 40/100 * $21 = $8.40.

To find the original price of the sweater, we then need to subtract the discount from the sales price. Since the sales price was $21 and the discount was $8.40, the original price of the sweater was $21 - $8.40 = $<<21-8.4=12.60>>12.60.

However, since the problem states that the original price of the sweater was $35, we can conclude that the calculation above must be incorrect. To find the correct original price of the sweater, we need to divide the sales price by the discount percentage, rather than subtracting the discount amount from the sales price.

Using this method, we can calculate the original price of the sweater by dividing the sales price of $21 by the discount percentage of 40/100, which gives us $21 / (40/100) = $35. This is the correct original price of the sweater
