The amount earned by $3000 deposited in the account after 6 months is $60.30

What does quarterly compounding mean?

Quarterly compounding means that the interest is computed and credited to the account every quarter, that is every 3 months, in other words, our future value formula would indicate quarterly interest rate rather than an annual interest rate

FV=PV*(1+r)^N

FV=the amount in the account after 6 months=unknown\

PV=initial amount deposited in the account=$3,000

r=quarterly interest rate=4%/4=0.01

N=number of quarters in 6 months=2

FV=$3000*(1+0.01)^2

FV=$3000*(1.01)^2

FV=$3000*1.0201

FV=$ 3,060.30

amount earned=FV-PV

amount earned=$3060.30-$3000

Let x represent the number of math problems that you completed.

Let y represent the number of biology problems that you completed

From the information given,

You completed a total of 15 problems. This means that

x + y = 15

If each math problem takes 5 minutes to complete, it means that the time to complete x math problems is 5 * x = 5x

If each biology problem takes 3 minutes to complete, it means that the time to complete y biology problems is 3 * y = 3y

If you spent 51 minutes working on your homework problems for math and

biology, it means that

5x + 3y = 51

Thus, the system of equations is

x + y = 15

5x + 3y = 51

Answer:

That depends on what exactly is meant by "$3 in equipment fees". Is that per hour, per day or what?

Assuming per hour, he makes $7 per hour but pays $3 for a profit of $4 per hour. So, to make at least $39, he'd have to work 39/4 or 9 3/4 hours.

Now, if his equipment fee is daily, then he would need to earn at least $42 in a day to profit at least $39. Thus, he'd have to work at least 42/7 or 6 hours to make that much profit.

Step-by-step explanation:

The Simple interest after three month $423.70

What is Simple Interest ?

Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.

If she deposits $366 in the account and you receive interest, you must first calculate the interest for the current year before adding the sum to calculate the interest for the following month.

for instance, deposit plus interest equals the new amount for month one, month one amount plus interest equals amount for month two, and month two amount plus interest equals amount for month three.

The total would thus be $423.70 for the following month:

month 1

366+ (366*.05)=x

366+18.3=x

month 2

384.30+(384.30*.05)=x

384.30+19.22=x

month 3

403.52+(403.52*.05)=x

403.52+20.18=x

423.7 = x

Thus, total amount then would be $423.70

Answer:

C' = (13, 4)

Dilation by a scale factor of 2 with the origin (0, 0) as the center of dilation, followed by a translation of 3 units right.

Step-by-step explanation:

Given vertices of triangle ABC:

If two triangles are said to be similar:

To keep the corresponding angles of both triangles the same and maintain similarity, dilate triangle ABC.

If we compare the coordinates of B (1, 4) and B' (5, 8), the y-value has been multiplied by 2.

Therefore, the first step of the transformation is a dilation by a scale factor 2 with the origin (0, 0) as the center of dilation.

⇒ (1 × 2, 4 × 2) = (2, 8)

After multiplying the coordinates of B by two, the difference between the x-values of the dilated point and B' is 3, so the second step of the transformation is a translation of 3 units right.

Therefore, the series of transformations is:

Mapping Rule:  (x, y) → (2x+3, 2y)

Therefore, the coordinates of point C' are:

⇒ C' = (2(5) + 3, 2(2)) = (13, 4)

Answer:   (13, 4)

Infinitely many answers are possible.

because I'll be using the same steps and ideas. There are also diagrams that might help visualize what's going on.

---------

The translation vector from B(1,4) to C(5,2) is <4,-2> since we move to the right 4 units, and down 2 units. It's the shorthand way of writing [tex](x,y) \to (x+4,y-2)[/tex]

Double the coordinates of the translation vector <4,-2> to get <8,-4>

If we started at point B'(5,8) and followed the pathway "right 8, down 4" then we arrive at C'(13,4) as one possible answer.

We could express the steps like this

[tex](\text{x},\text{y})\to(\text{x}+8,\text{y}-4)\\\\(5,8)\to(5+8,8-4)\\\\(5,8)\to(13,4)\\\\[/tex]

As I mentioned in the link above, there are infinitely many answers because we can change the scale factor to any nonnegative real number. For instance we could triple the coordinates of <4,-2> to get <12,-6> and follow the same outline of steps to get C'(17,2) as another possible answer.

Step-by-step explanation:

Let use the following rules to construct a polynomial,

Rule 1:

If r is a zero of some polynomial, f(x), then

[tex](x - r)[/tex]

is a factor of the polynomial

We first know that one of our zeroes are real, which is 0.

So since r=0

[tex](x - 0) = x[/tex]

is a factor

However, since the root ,0, has a multiplicty of 4, that basically means we have 0 as a root 4 times or basically we multiply the factor 4 times.

[tex]x \times x \times x \times x = x {}^{4} [/tex]

This leads to an another rule:

If a polynomial has a zero, r that has a multiplicty of k,

we represent the factor as

[tex](x - r) {}^{k} [/tex]

where k is all integers greater than 0.

So to reinforce myself, since 0 has a multiplicty of 4, we have

[tex](x - 0) {}^{4} = {x}^{4} [/tex]

So our first factor is

[tex] {x}^{4} [/tex]

Part 2: Complex Zeroes.

When dealing with complex zeroes, we must note this rule.

if (a+bi) is a zero of some polynomial, p then its conjugate (a-bi) is a factor as well.

So if 3-2i is a factor, then

3+2i is a factor as well.

Using Rule 1, our factors now become

[tex](x - (3 + 2i))[/tex]

and

[tex](x - (3 - 2i))[/tex]

So our factors are

[tex] {x}^{4} (x - (3 - 2i)(x - (3 + 2i))[/tex]

To simplify use FOIL Method,

[tex] {x}^{4} ( {x}^{2} - x(3 + 2i) - x(3 - 2i) + 9 - 4 {i}^{2} )[/tex]

[tex] {x}^{4} ( {x}^{2} - 6x + 13)[/tex]

[tex] {x}^{6} - 6 {x}^{5} + 13 {x}^{4} [/tex]

So our polynomial is

[tex] {x}^{6} - 6 {x}^{5} + 13 {x}^{4} [/tex]

Step-by-step explanation:

(a)

the 2 angles are vertically opposite angles and are congruent

(c)

since they are congruent , then

7x + 6 = 6x + 18 ( subtract 6x from both sides )

x + 6 = 18 ( subtract 6 from both sides )

x = 12

(d)

then

7x + 6 = 7(12) + 6 = 84 + 6 = 90

6x + 18 = 6(12) + 18 = 72 + 18 = 90

20 miles per hour converted to feet per second is 88/3 feet per second.

It is given in the question that there are 60 minutes in one hour and 60 seconds in one minute.

We have to convert 20 miles per hour in feet per second.

We know that,

1 mile = 5280 feet

1 hour = 60 minutes

1 minute = 60 seconds

Hence, we can write,

1 hour = 60*60 = 3600 seconds

1 mile per hour = 5280/3600 feet per second = 22/15 feet per second

Using unitary method, we can write,

20 miles per hour = 20*(22/15) = 88/3 feet per second or 29.3334 feet per second.

If Scampini has no debt or preferred stock, and its WACC is 12%, and it has zero nonoperating assets in which Scampini has 40 million shares of stock outstanding, the stock's value per share is $37.50.

Next year CF = $75 millions

Growth rate of CF = 7%

WACC = 12%

Number of shares outstanding = 40 million shares

Estimated business valuation:

Valuation = Next year CF/ (WACC -growth rate)

Valuation = $75 million / (12% - 7%)

Valuation = $75 million /5%

Valuation =$1500 million

An expression exists as a number, a variable, or a combination of numbers and variables, and function symbols. The speed in still water exists 4 mph.

The acronym BODMAS, which stands for brackets of, division, multiplication, addition, and subtraction, might be used to simplify the expression. It specifies how to answer a mathematical expression in a particular order.

Let x be the speed in still water

[tex]$&\frac{5}{x+1}+\frac{6}{x-1}=3[/tex]

LCD = (x + 1)(x - 1)

[tex]$&(x+1)(x-1) \cdot \frac{5}{x+1}+(x+1)(x-1) \cdot \frac{6}{x-1}=(x+1)(x-1) \cdot 3 \\[/tex]

simplifying the above equation, we get

5(x - 1) + 6(x + 1) = 3(x + 1)(x - 1)

5x - 5 + 6x + 6 = 3 x² - 3

3x² - 11x - 4 = 0

(3x + 1)(x - 4) = 0

x = -1/3 (speed is not negative);

The probability of an actress getting a job after a tryout is 0.11.

The actress wants to keep trying out for new jobs until she gets offered one.

The number of trials necessary for success in a series of independent trials follows a geometric distribution with parameter p, where p is the probability of success in a single trial.

The probability mass function is given as:

[tex]P(X=k)=q^{k-1}p[/tex] where k = 1, 2, 3

We have p = 0.11

q = 1 - 0.11 = 0.89

If X is the number of tryouts,

[tex]P(X=k)=q^{k-1}p\\P(X=k)=(0.89)^{k-1}(0.11)[/tex]

[tex]P(X\leq r)=1-q^r\\P(X\leq r)=1-(0.89)^r[/tex]

Therefore, the probability that she will need to attend more than 3 try outs will be:

P = P( X > 3 )
