we can use the fact that anything multiplied by 1 results in the same value to simplify the expression:

   (3x + 2)(x - 5) / (3x + 4)(x - 5)  =  (3x + 2)/(3x + 4)

To obtain an equivalent expression for (3x+2)/(x-5) with a denominator of (3x+4)(x-5), we can use the distributive property to expand the numerator and denominator:

   (3x + 2) / (x - 5)  =  (3x + 2)(x - 5) / (3x + 4)(x - 5)

From here, we can use the fact that anything multiplied by 1 results in the same value to simplify the expression:

   (3x + 2)(x - 5) / (3x + 4)(x - 5)  =  (3x + 2)/(3x + 4)

for % questions always find 100% and/or 1%.

everything else can be easily calculated out of these 2.

the original price of $210 = 100%, as we want to know how many % the new price is different from that.

100% = $210

1% = 100%/100 = 210/100 = $2.10

the new price is $300.

the difference is 300 - 210 = $90

how many % are $90 compared to the original price ?

well, as many as the times 2.1 (1%) fits into 90 :

90/2.1 = 42.85714286...%

that increase from $210 to $300 was 42.85714286...%.

In the following question, Jordan needs 2200 square centimetres of carpet to cover the surface of the post, including the bottom.

To find the surface area of the scratching post, we need to add up the surface areas of all the sides.

The scratching post has a rectangular prism shape with dimensions of 10 cm x 10 cm x 90 cm. The bottom is also a 10 cm x 10 cm square.

So the surface area of the post, including the bottom, is:

2(10 cm x 10 cm) + 2(10 cm x 90 cm) + 2(10 cm x 10 cm) = 200 cm^2 + 1800 cm^2 + 200 cm^2 = 2200 cm^2

The polynomial f(x) of degree 3 with real coefficients and the given zeros is f(x) = x³ - x² + 4x + 2.

To find a polynomial f(x) of degree 3 with real coefficients and the given zeros, we need to use the fact that if a polynomial has a complex root, then its conjugate is also a root. This means that if 1-i is a root, then 1+i is also a root.

So, our polynomial f(x) has the following roots: -1, 1-i, 1+i.

We can write the polynomial as the product of its factors:

f(x) = (x - (-1))(x - (1-i))(x - (1+i))

Simplifying the factors:

f(x) = (x + 1)(x - 1 + i)(x - 1 - i)

Multiplying the factors:

f(x) = (x + 1)(x² - 2x + 2)

Expanding the polynomial:

f(x) = x³ - 2x² + 2x + x² - 2x + 2

Simplifying the polynomial:

f(x) = x³ - x² + 4x + 2

The simplified rational expression is (x³-6x²+5x²)-30x+5x²-30x+25x-150)/(x³+17x²+75x+175)

To simplify the rational expression, we will need to use multiplication and division of the rational expressions. We will also need to factor the expressions in order to simplify them.

First, let's factor the expressions:
(x²-3x-18)/(x²+10x+21)-:(x²+3x-54)/(x²-x-30)*(x²+16x+63)/(x²+14x+45)

= ((x-6)(x+3))/((x+7)(x+3))-:((x+9)(x-6))/((x-6)(x+5))*((x+9)(x+7))/((x+9)(x+5))

Next, let's simplify the expressions by canceling out the common factors:
= (x-6)/(x+7)-: (x+9)/(x+5)*(x+7)/(x+5)
= (x-6)/(x+7)-: (x+9)(x+7)/(x+5)(x+5)

Now, let's multiply the expressions:
= (x-6)(x+5)(x+5)/(x+7)(x+5)(x+5) - (x+9)(x+7)(x+7)/(x+7)(x+5)(x+5)

Finally, let's subtract the expressions:
= ((x-6)(x+5)(x+5) - (x+9)(x+7)(x+7))/((x+7)(x+5)(x+5))
= (x³-6x²+5x²-30x+5x²-30x+25x-150)/(x²+17x²+75x+175)

To solve this problem, use logarithmic properties to combine the two equations into one.

First, use the product rule to combine the two equations:
$\log_2(32) + \log_2(x-4) + \log_2(x) = 5$
Then use the power rule to combine the last two terms:
$\log_2(32) + \log_2(x^2 - 4x) = 5$
Finally, use the quotient rule to separate the terms:
$\log_2\frac{32}{x^2 - 4x} = 5$

To solve for $x$, take the inverse logarithm of both sides:
$\frac{32}{x^2 - 4x} = 2^5$
Expand and simplify the left side to get a quadratic equation:
$x^2 - 4x - 32 = 0$
Solve the quadratic equation using the quadratic formula:
$x = \frac{4 \pm \sqrt{4^2 + 4(32)}}{2}$
$x = \frac{4 \pm \sqrt{136}}{2}$
$x = 4 \pm \sqrt{17}$

Therefore, the solutions are:
$x = 4 + \sqrt{17}$

According to the model from part (a), the equation for the logarithm of annual salary is:

log(salary) = 4.62 + 0.16 sales + 0.11 log(mktval) + u

where u is the error term. This model has a multiple R-squared of 0.30, which means that it explains 30% of the variation in salaries based on sales and market value.

log(salary) = 4.62 + 0.16 x log(500000) + 0.11 x log(20000000)

log(salary) = 4.62 + 0.16 x 13.122 + 0.11 x 16.811

log(salary) = 7.625

salary = exp(7.625)

salary = $2,178,357

We can also use the coefficients from the model to calculate the expected salary directly, without taking logarithms.

salary = exp(β0) x sales^β1 x mktval^β2 x e^u

salary = exp(4.62) x 5,000,000^0.16 x 20,000,000^0.11 x e^u

salary = $2,178,357 x e^u

Using this assumption, we can calculate a 95% confidence interval for the expected salary:

log(salary) = 7.625

standard error = 535.9 x sqrt(0.16^2 + 0.11^2) = 136.6

The number that if decreased by one fifth of itself gives 132 is 165.

To solve this problem, we can use algebra to create an equation and then solve for the unknown number.

Let x be the number we are trying to find.

If the number decreased by one-fifth of itself yields 132, we can write the equation:

x - (1/5)x = 132

Simplifying the equation, we get:

(4/5)x = 132

Multiplying both sides by 5/4 to isolate x, we get:

x = (5/4)(132)

x = 165

Therefore, the number that decreased by one-fifth of itself yields 132 is 165.

Alternatively, we can use a different method to solve the problem.

If the number decreased by one-fifth of itself yields 132, we can write the equation:

x - (x/5) = 132

Multiplying both sides by 5 to eliminate the fraction, we get:

5x - x = 660

Simplifying the equation, we get:

4x = 660

Dividing both sides by 4 to isolate x, we get:

The answer of values of m for which the equation has two complex (non-real) solutions are all values greater than 1/8. In other words, m > 1/8

To find all values of m for which the equation has two complex (non-real) solutions, we need to use the discriminant of the quadratic formula.

The discriminant is the part of the quadratic formula under the square root: b²-4ac. If the discriminant is less than 0, then the equation will have two complex (non-real) solutions.

So, let's start by setting the discriminant to be less than 0:

b²-4ac < 0

Now, let's plug in the values from the equation into the discriminant. The equation is in the form ax²+bx+c=0, so we can plug in the values for a, b, and c:

(1)²-4(m)(2) < 0

Simplify:

1-8m < 0

Subtract 1 from both sides:

-8m < -1

Divide both sides by -8:

Var(θ3) = (a-1)(a-2) / λ^2 - θ^2.

First, let's find the method of moments estimate of θ based on Y1,...,Yn. We know that E(Y) = E(log(X/x0)) = E(log(X)) - log(x0) = θ^-1 - log(x0). Therefore, θ^-1 = E(Y) + log(x0) and θ3 = 1 / (E(Y) + log(x0)).

Next, let's find the distribution of Y. Since Y = log(X/x0), we can use the change of variables formula to find the density function of Y. Let g(y) = x0 * exp(y), then the Jacobian is |g'(y)| = x0 * exp(y). The density function of Y is fY(y) = fX(g(y)) * |g'(y)| = θ * (x0 * exp(y))^θ * (x0 * exp(y))^(-θ-1) * x0 * exp(y) = θ * x0^θ * exp(-θy).

Finally, let's find the mean and variance of θ3. We know that E(θ3) = E(1 / (E(Y) + log(x0))) = 1 / (E(Y) + log(x0)) = θ. To find the variance, we can use the fact that Var(θ3) = E(θ3^2) - E(θ3)^2. We can use the fact that if U follows a gamma distribution, then E(U^r) = Γ(a+r) / [λ^r * Γ(a)] to find E(θ3^2). Let U = E(Y) + log(x0), then E(θ3^2) = E(U^-2) = Γ(a-2) / [λ^2 * Γ(a)] = (a-1)(a-2) / λ^2. Therefore, Var(θ3) = (a-1)(a-2) / λ^2 - θ^2.

Step-by-step explanation:

If Jason claims no allowances this year, $17 more will be deducted from his weekly check for taxes compared to last year when he claimed one allowance.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

The amount of money deducted from Jason's paycheck for taxes depends on the number of allowances he claims.

Claiming more allowances reduces the amount of taxes withheld from his paycheck while claiming fewer allowances increases it.

If Jason claimed 1 allowance last year, his employer would have withheld taxes from his paycheck based on that information.

If he claims no allowances this year, more taxes will be withheld.

To calculate how much more will be deducted from his weekly check if he claims no allowances, we need to know his tax bracket and the amount of taxes that will be withheld for each allowance.

Assuming Jason is paid on a weekly basis, we can use the IRS tax withholding tables for 2021 to estimate the additional amount of taxes that will be withheld if he claims no allowances.

Using these tables, we find that for a single person earning $232.50 per week, claiming no allowances would result in an additional withholding of $17 per week.

Therefore, claiming no allowances would result in an additional withholding of $17 per week.
