Answer: No

Step-by-step explanation:

The graph is increasing, yet as p increases, the value of 100/p decreases, meaning that the graph should be decreasing.

Step-by-step explanation:

0 <= income <= 31000 : 10.8%

31000 < income <= 31000+36000 = 67000 : 12.75%

67000 < income < anything above 67000 : 17.4%

the total income is

$85,000

the taxes paid are

10.8% of 31000 = $3348

12.75% of 67000 - 31000 = 12.75% of 36000 = $4590

17.4% of 85000 - 67000 = 17.4% of 18000 = $3132

so, out of $85000 you paid

3348

4590

3132

----------

$11,070

taxes

100% = 85000

1% = 100%/100 = 85000/100 = 850

how many % are 11070 ?

well, as many as how often 1% fits into that amount :

11070 / 850 = 13.02352941...% ≈ 13.02%

Answer:

y = -5x - 11

Step-by-step explanation:

We are given that a line passes through the point (-3,4) and also has a slope of -5.

We want to write an equation of this line.

The equation of the line can be written in 3 different ways:

Since the question did not specify, any of these 3 options will be valid, however, the most common way to write the equation of the line is in slope-intercept form, so let's do it that way.

Because we are already given the value of the slope, we can immediately plug that into the equation.

Replace m with -5.

y = -5x + b

Now we need to find b.

As the equation passes through the point (-3, 4), we can use its values to help solve for b.

Substitute -3 as x and 4 as y.

4 = -5(-3) + b

Multiply

4 = 15 + b

Subtract 15 from both sides.

-11 = b

Substitute -11 as b in the equation.

y = -5x - 11

Step-by-step explanation:

Por la ecuación de utilidad, necesitamos una producción de 7,667 botellas de un litro de capacidad para obtener un total de utilidades de S/ 30.000.

Las utilidades (U') se obtienen de sustraer los costes de producción (Cp) a las utilidades netas (U). Los costes de producción (Cp) son la suma de costes variables (C') y costes fijos (C). y la utilidades netas proceden de la venta de botellas. En consecuencia, tenemos la siguiente expresión:

U' = U - Cp

U' = U - C' - C

A continuación, desarrollamos y resolvemos la ecuación resultante:

30000 = 4.50 · x - 2.50 · x - 18500

1.50 · x = 11500

x = 7667

The amount and compound interest are Rs22169.11 and Rs6169.11 respectively

The formula for calculating the compound interest is expressed as:

P(t) = P0(1+r)^t

Substitute the given parameters

P(7/3) = 16000(1+0.15)^7/3

P(7/3) = 16000(1.15)^7/3

P(7/3) = 22169.11

For the interest

There's nothing particularly tricky about the limits of integration. The upper limit is a telescoping series converging to 2,

[tex]\displaystyle \sum_{n=1}^\infty \frac4{4n^2-1} = 2 \sum_{n=1}^\infty \left(\frac1{2n-1} - \frac1{2n+1}\right) \\\\ ~~~~~~~~ = 2 \left(\left(1-\frac13\right)+\left(\frac13-\frac15\right) + \left(\frac15 - \frac17\right) + \cdots\right)[/tex]

The lower limit reduces to 0 using the Riemann-Liouville definition of the fractional derivative. For [tex]q\in\Bbb Q[/tex], let

[tex]\displaystyle \frac{d^q}{dx^q} f(x) = \frac1{\Gamma(\lceil q\rceil-q)} \frac{d^{\lceil q\rceil}}{dx^{\lceil q\rceil}} \int_a^x (x-t)^{\lceil q\rceil-q-1} f(t) \, dt[/tex]

With [tex]a=0[/tex], [tex]q=\frac12[/tex] and [tex]\lceil q\rceil=1[/tex], it follows that

[tex]\displaystyle \frac{d^{1/2}}{dx^{1/2}} 1 = \frac1{\Gamma\left(\frac12\right)} \frac d{dx} \int_0^x (x-t)^{-1/2} \, dt = \frac1{\sqrt{\pi x}}[/tex]

Let

[tex]\displaystyle I = \int_0^2 \frac{\tan^{-1}\left(\frac{2-x}{1+2x}\right)}{x^2-4x-1} \, dx[/tex]

Observe that

[tex]f(x) = \dfrac{2-x}{1+2x} = f^{-1}(x)[/tex]

is its own inverse, so by substituting [tex]\frac{2-x}{1+2x}\mapsto x[/tex], we get the equivalent integral

[tex]\displaystyle \int_0^2 \frac{\tan^{-1}(x)}{x^2-4x-1} \, dx[/tex]

We have the identity

[tex]\tan^{-1}(x) + \tan^{-1}\left(\dfrac{2-x}{1+2x}\right) = \tan^{-1}(2)[/tex]

so that

[tex]\displaystyle I + I = \int_0^2 \frac{\tan^{-1}\left(\frac{2-x}{1+2x}\right) + \tan^{-1}(x)}{x^2-4x-1} \, dx[/tex]

[tex]\implies \displaystyle I = \frac{\tan^{-1}(2)}2 \int_0^2 \frac{dx}{(x-2)^2-5}[/tex]

The remaining integral is trivial,

[tex]\displaystyle \int_0^2 \frac{dx}{(x-2)^2-5} = \int_{-2}^0 \frac{dx}{x^2-5} \\\\ ~~~~~~~~ = \frac1{2\sqrt5} \int_{-2}^0 \left(\frac1{x-\sqrt5} - \frac1{x+\sqrt5}\right) \, dx \\\\ ~~~~~~~~= -\frac{\ln(2+\sqrt5)}{2\sqrt5} \\\\ ~~~~~~~~ = -\frac1{\sqrt5} \tanh^{-1}\left(\dfrac2{\sqrt5}\right)[/tex]

Then the integral we want is

[tex]I = \displaystyle \int_0^2 \frac{\tan^{-1}\left(\frac{2-x}{1+2x}\right)}{x^2-4x-1} \, dx = \boxed{-\frac1{2\sqrt5} \tan^{-1}(2) \, \tanh^{-1}\left(\dfrac2{\sqrt5}\right)} \approx -0.357395[/tex]

Answer:

Emily raised $37.50

Justin raised $57.50

Step-by-step explanation:

(Step 1)

Say "x" equals the amount of money Emily made and "y" equals the amount of money Justin made. You can set up an equation with both of these variables because we know that they made a combined $95.

x = Emily's earnings

y = Justin's earnings

Emily + Justin = 95

x + y = 95

(Step 2)

The fact that there are two variables makes it difficult to find how much each person made individually. However, we can eliminate the "y" variable when we remember that Justin made $20 more than Emily. Now, we can substitute "x + 20" in for "y".

x + 20 = y

x + y = 95

x + (x + 20) = 95

(Step 3)  

Finally, we can solve for the "x" variable.

x + (x + 20) = 95

2x + 20 = 95                                <------ Combine like terms

2x = 75                                         <------ Subtract 20 from both sides

x = 37.5                                        <------- Divide both sides by 2

(Step 4)

Since we know the value of "x", we can plug it into one of the equations to find the value of "y".

x + 20 = y

37.5 + 20 = y

y = 57.5

Answer:

Emily raised $37.5 and justin raised $57.5

The ratio of blue paint to yellow paint is 2 : 3.

The total number of blue paint he used on the first and second day is 10.

The number of yellow paint he used on the first and second day is 15.

On the third day, the highest number of can of blue paint he can use is 2

On the third day, the highest number of can of yellow paint he can use is 3.

The ratio of blue paint to yellow paint can be determined by determining the simplest form of the paints used: 4 : 6 = 2: 3

Total blue paint cans used on the first and second day = 4 + 6 = 10

Blue paint cans remaining = 14 - 10 = 4

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

a. Find the probability that a randomly selected student is from east of the school and in the math club:

P(east ∩ math club)  = 0.6×0.3 = 0.18

b. Given that a student is from west of the school, what is the probability that he or she is in the math club?

P(west ∩ math club)  = 0.4×0.2 = 0.08

c. Is participation in the math club independent of whether a student lives east or west of the school?
