Mika opened a bank account that earns simple interest with an initial deposit of $2,200.She made no other transactions throughout the year. At the end of the year, Mika had $2,260.50 in her account. What was the simple interest rate?

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]

Kevin is not correct

What is linear equation?

At first it is important to know about equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Here,

Let Kevin has x times as many stamps as stamp

Jackie has 9 stamps

Number of stamps Kevin has = 9x stamps

By the problem,

                          9x = 36

                            [tex]x = \frac{36}{9}[/tex]

                            x = 4

So Kevin has 4 times as many stamps as Jackie

But Kevin says  he has 5 times as many stamps as Jackie.

So Kevin is not correct.

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

Step-by-step explanation:

Put the point in the middle of 2 and 5 and count how many times you need to get there ...

like 0.05 to put point after 5 you have to jump 2 steps so it is 5×10^-2.

the height in the first case will be 191 cm and the weight in the second case will be 106 kg.

We are given the function as:

BSA = √( w h / 3600)

where:

h = height

w = weight

BSA = body surface area

1) Now, for w = 68 kg and BSA = 1.9, we get the height as:

1.9 = √( (68) h / 3600)

3.61 = 68 h / 3600

12,996 = 68 h

h = 12996 / 68

h = 191.12 cm

h ≈ 191 cm

2) for h = 165 cm and BSA = 2.2, we get the weight as:

2.2 = √( w (165) / 3600)

4.48 = 165 w / 3600

17424 = 165 w

w = 17424/ 165

w = 105.6 kg.

w ≈ 106 kg

Therefore, we get that, the height in the first case will be 191 cm and the weight in the second case will be 106 kg.

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 she will need to attend more than 3 try-outs is 0.7049.

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 )

P = 1 - P( X ≤ 3 )

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
