After 6 years, Marta will owe $19,461 on her loan.

What is compound interest?

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

We can use the formula for compound interest to find the amount owed after 6 years:

A = \(P(1 + r/n)^{(nt)\)

In this case, we have:

P = $13,225

r = 6.58% = 0.0658 (note that the annual interest rate is given as a percentage, so we need to convert it to a decimal)

n = 4 (since the interest is compounded quarterly)

t = 6

Plugging these values into the formula, we get:

A = \(13,225(1 + 0.0658/4)^{(4*6)\)

A =  19,461.21

Rounding this to the nearest dollar, we get that the amount owed after 6 years is approximately $19,461.

Hence,  after 6 years, Marta will owe $19,461 on her loan.

The distribution of the given function is a uniform distribution.

A strictly increasing function is the one which increases continuously in a given interval. If f-1(u) is a strictly increasing function of u, then the distribution of f-1(u) is the same as that of u. This is because a strictly increasing function preserves the rank ordering of its input, so if u-1 and u-2 are two random variables with a uniform distribution on the interval (0,1), then the rank order of f-1(u-1) and f-1(u-2) will be the same as the rank order of u-1 and u-2. Since the uniform distribution is defined by the rank order of its values, this means that the distribution of f-1(u) is also uniform on the interval (0,1).

Answer: The variable that will be eliminated when the equations are combined after the multiplication is y.

Step-by-step explanation: Happy to help :D

The elements of the set A={x∈Z∣x^2≤50 and (2x≥9 or 3x+7≤0)} are:

A={−7,−6,−5,−4,−3,−2,5,6,7}

To find the elements of the set A, we need to consider the conditions given in the set builder notation.

Condition 1: x^2≤50 This condition implies that the square of x should be less than or equal to 50. Therefore, the possible values for x can be any integer between -7 and 7, as the squares of these numbers are less than or equal to 50.

Condition 2: 2x≥9 or 3x+7≤0 This condition implies that either 2x is greater than or equal to 9 or 3x+7 is less than or equal to 0.

For 2x≥9, we solve for x: 2x≥9 x≥9/2 x≥4.5

For 3x+7≤0, we solve for x: 3x+7≤0 3x≤-7 x≤-7/3 x≤-2.33 (rounded to two decimal places)

Considering both conditions together, the values of x that satisfy at least one of the conditions are: x={−7,−6,−5,−4,−3,−2,5,6,7}

Therefore, the correct answer is:

A={−7,−6,−5,−4,−3,−2,5,6,7}

The set A consists of the elements −7,−6,−5,−4,−3,−2,5,6,7. These are the values of x that satisfy the given conditions in the set builder notation.

13.50<= 1.20c + 3 is the inequality

We can see that it costs her $3 in addition to the $1.20 she receives for each task she completes, which is "C," for a total of $13.50.

Start by deducting her initial investment ($3) from the total ($13.50) to find the solution. By doing this, you'll discover that Janie needs to earn $10.50 in order to meet her goal, and since she receives $1.20 for EVERY chore, you'll also want to determine how many chores it will take her to reach that amount. You can calculate this by simply dividing $10.50 by $1.20, which gives you the total number of tasks she must complete, which is 8 and third tasks.

Answer:

150

Step-by-step explanation:

because you have to subtract 450 - 300 to get the net force

Force F1= 450 N

Force F2 = -300 N

The net force formula is given by

FNet = F1 + F2

FNet  = 450 + (-300)

FNet  = 450-300

FNet = 150 N

Therefore, the net force is 150 N.

Let's assume that the number of attendees for the party is "x". We want to find the number of attendees for which the cost of the two venues will be the same.

The cost of the hotel in Stafford can be expressed as:

Total cost of the hotel = $500 + $4x

The cost of the restaurant can be expressed as:

Total cost of the restaurant = $200 + $7x

To find the number of attendees for which the cost of the two venues will be the same, we can set the two equations equal to each other and solve for x:

$500 + $4x = $200 + $7x

$500 - $200 = $7x - $4x

$300 = $3x

x = 100

Therefore, if the number of attendees is 100, the total cost of the hotel and the restaurant will be the same. To find the total cost, we can substitute x=100 into either equation:

Total cost = $500 + $4(100) = $900 (for the hotel)

or

Total cost = $200 + $7(100) = $900 (for the restaurant)

Therefore, the total cost for either venue when the number of attendees is 100 is $900.

We see that \(B(S^-1x) = λ(S^-1x)\), which means that S^-1x is indeed an eigenvector of B with eigenvalue λ, as required.

First, let's recall the definition of eigenvectors and eigenvalues. An eigenvector of a matrix A is a non-zero vector x such that Ax = λx for some scalar λ, which is called the eigenvalue corresponding to x.

Now, suppose x is an eigenvector of A with eigenvalue λ. We want to show that S^-1x is an eigenvector of B with the same eigenvalue λ.

To do this, let's apply B to S^-1x:

\(B(S^-1x) = (S^-1AS)(S^-1x)

[using the fact that S^-1AS = B] = S^-1A(SS^-1)x  [associativity of matrix multiplication] = S^-1Ax  

[since SS^-1 = I, the identity matrix] = S^-1(λx)  

[using the fact that x is an eigenvector of A with eigenvalue λ] = λ(S^-1x)  [distributing λ over S^-1x]\)

So, we see that B(S^-1x) = λ(S^-1x), which means that S^-1x is indeed an eigenvector of B with eigenvalue λ, as required.

A scaled-down version of the right triangle on the left, where the fraction is 54, is shown on the right.

A scaled-down version of the right triangle on the left can be seen in the right triangle on the right. The scaling factor should be recognised as a whole integer or simplest possible fraction. In order to relate these two sides, we will choose the number 15 since it is a finer number than 254 and is therefore the longer of the two sides that correlate to the number 12.

And since we're moving in this direction and getting bigger, the scale factor needs to be greater than 1 . Consider the difference between the original corresponding length of 12 and the new length of 15, which is 15. Because 15 is three times the original length of 12, the difference between 15 and 12 may be simplified. Though your response is 54.

All four are clubsThere are 52 cards in a standard deck, and there are 13 clubs.Option A is the correct answer.

If four cards are drawn from a deck, the number of ways to draw four clubs is:13C4 = 715The total number of ways to draw four cards from a deck is:52C4 = 270,725The probability of drawing all four clubs is, therefore:715/270725 = 0.00264 or 0.264%b. At least one is not a clubTo find the probability that at least one card is not a club, we must first find the probability that all four cards are clubs. We can then subtract this probability from 1 to get the probability of drawing at least one card that is not a club:

P(at least one non-club) = 1 - P(all four clubs)P(all four clubs) = 715/270725 (as calculated above)P(at least one non-club) = 1 - 715/270725 = 269,010/270725 = 0.9938 or 99.38%Therefore, the probability of drawing at least one card that is not a club is 0.9938.c. Three are black and one is redTo find the probability that three cards are black and one is red, we must first determine how many ways there are to select three black cards and one red card. There are 26 black cards (clubs and spades) and 2 red cards (diamonds and hearts), so the number of ways to draw three black cards and one red card is:26C3 * 2C1 = 2,600The total number of ways to draw four cards from the deck is 52C4 (as calculated above), so the probability of drawing three black cards and one red card is:2,600/270,725 = 0.0096 or 0.96%d. Exactly two are picture cardsTo find the probability of drawing exactly two picture cards, we first must determine how many picture cards are in the deck.

There are 12 picture cards (4 jacks, 4 queens, and 4 kings).The number of ways to draw two picture cards is:12C2 = 66The number of non-picture cards is 40 (52 cards - 12 picture cards), so the number of ways to draw two non-picture cards is:40C2 = 780The total number of ways to draw four cards is 52C4, as calculated above, so the probability of drawing exactly two picture cards is:(66 * 780)/270,725 = 0.1905 or 19.05%e.

Either two or three of the four cards are picture cardsThe number of ways to draw two picture cards and two non-picture cards is:12C2 * 40C2 = 77,880The number of ways to draw three picture cards and one non-picture card is:12C3 * 40C1 = 1,680The total number of ways to draw four cards is 52C4, as calculated above, so the probability of drawing either two or three picture cards is:(77,880 + 1,680)/270,725 = 0.3026 or 30.26%Therefore, the probability of drawing four cards from a deck of 52 cards as described above is:a. All four are clubs = 0.00264 or 0.264%b. At least one is not a club = 0.9938 or 99.38%c. Three are black and one is red = 0.0096 or 0.96%d. Exactly two are picture cards = 0.1905 or 19.05%e.

The matrix A is [-2 -3 1 3]. This matrix satisfies the given equation A * [1 0 -1 3] = [-2 -3 1 9], and it can be represented as the matrix A = [-2 -3 1 3].

To find the matrix A such that A * [1 0 -1 3] = [-2 -3 1 9], we can express A as a 2x2 matrix with elements a, b, c, and d. By equating the corresponding entries on both sides of the equation, we can solve for the values of a, b, c, and d. The resulting matrix A is [-2 -3 1 3]. Let A = [a b c d] be the 2x2 matrix we are looking for. We want to find the values of a, b, c, and d such that A * [1 0 -1 3] = [-2 -3 1 9]. Multiplying the matrices, we get:

a * 1 + b * (-1) = -2     (Equation 1)

a * 0 + b * 3 = -3        (Equation 2)

c * 1 + d * (-1) = 1      (Equation 3)

c * 0 + d * 3 = 9         (Equation 4)

From Equation 1, we have a - b = -2.

From Equation 2, we have 3b = -3, which implies b = -1.

From Equation 3, we have c - d = 1.

From Equation 4, we have 3d = 9, which implies d = 3.

Substituting the values of b and d back into Equations 1 and 3, we find a = -1 and c = 4. Thus, the matrix A is [-2 -3 1 3]. This matrix satisfies the given equation A * [1 0 -1 3] = [-2 -3 1 9], and it can be represented as the matrix A = [-2 -3 1 3].

Answer:

54 feet of yarn

Step-by-step explanation:

We have a conversion rate of

1 yard = 3 feet

Sarah has 4 pieces of yarn that are 6 yards each.

Hence,

1 yard = 3 feet

6 yards = x

Cross Multiply

x = 6 × 3 feet

x = 18 feet

Therefore, 4 pieces of yarn are 18 feet each

Hence, total feet of yarn above = 4 × 18 feet = 72 feet

She uses 9 pieces of yarn that are each 2 feet long.

Total feet of yarn here is:

9 × 2 feet = 18 feet of yarn

Therefore, the amount of yarn Sarah have left is calculated as:

72 feet - 18 feet

If they hadn't stopped at the gas station and had driven along the diagonal path, their trip would have been 12 miles shorter.

Step-by-step explanation:

Given that Gigi's Family left their house and drove 14 miles south to a gas station and then 48 miles east to a waterpark, to determine how much shorter would their trip to the waterpark have been if they hadn't stopped at the gas station and had driven along the diagonal path instead the following calculation must be performed, using the Pythagorean theorem:

14 ^ 2 + 48 ^ 2 = X ^ 2

196 + 2,304 = X ^ 2

√ 2500 = X

50 = X

14 + 48 - 50 = X

62 - 50 = X
