Answer:

Step-by-step explanation:

Given room looks like a rectangular room.Let w be the wide and l be long of the rectangular room respectively.Given,w=10 feet and l=24 feet.

we know area of the rectangular room= l*w

So,area=10*23

area=230 sq.feet

Given,cost of trim=$0.85 per foot

So,total cost =230* 0.85

=195.5

The roots of the auxiliary equation are 1.

To find the roots of the auxiliary equation for the given homogeneous fourth-order linear differential equation with constant coefficients, we need to substitute y = \(e^{rx}\) into the differential equation, where r is an unknown constant.

This substitution yields the characteristic equation.

Substituting y = \(e^{rx}\)into the differential equation gives us:

\(e^{rx}\) = 5 - x + \(x^2\) + 9\(e^x\)

Next, we divide both sides by e^x to simplify the equation:

e^(rx - x) = 5 - x + \(x^2\)

Simplifying further:

\(e^{rx - x}\) = \(x^2\) - x + 5

Taking the natural logarithm of both sides to remove the exponential:

rx - x = ln(\(x^2\) - x + 5)

Combining like terms:

(r - 1)x = ln(\(x^2\) - x + 5)

Now, for the equation to hold for all x, the coefficient of x on the left-hand side must be zero, giving us the auxiliary equation:

r - 1 = 0

Solving for r:

r = 1

Therefore, the roots of the auxiliary equation are 1 (with multiplicity 4) since it is a fourth-order differential equation.

Answer:

Step-by-step explanation:

ABD is a right-angled triangle, then the area of the shaded part will be equal to (3 - √6)/12 cm².

An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely encompass the surface of a compact figure.

The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.

As per the given figure and data in the question,

From Δ ACD

Area of triangle will be, a = 1/2 × b × h

a = 1/2 × (√2/2) × (√3/3)

a = √6/12 cm²

From Δ ABD

The area of the triangle will be, a' = 1/2 × b × h

a' = 1/2 × (√2/2) × (√2/2)

a' = 1/4 cm²

The area of the shaded portion in the triangle, s = a' - a

s = 1/4 - √6/12

s = (3 - √6)/12 cm²

Juana would have to pay approximately $29.40 in interest for the $10,686.00 loan over a 20-day period, assuming an annual interest rate of 5.79%.

The interest Juana would have to pay in 20 days can be calculated using the formula:

Interest = Principal × Interest Rate × Time

In this case, the principal amount is $10,686.00 and the interest rate is 5.79% per annum. To calculate the interest for 20 days, we need to convert the time to a fraction of a year. Since there are 365 days in a year, the time in years would be 20/365.

Using the formula and substituting the values:

Interest = $10,686.00 × 0.0579 × (20/365)

Calculating this expression, we find that the interest amount Juana would have to pay in 20 days is approximately $29.40.

The resulting expression from the factorization of 26r³s + 52r^(5) - 39r²s⁴ is; 13r²(2rs + 4r³ - 3s⁴)

We want to factor the algebraic expression;

26r³s + 52r^(5) - 39r²s⁴

Now, we need to first find the highest common factor here and factorize out.

First of all for the letters;

The highest common factor of the letters is r²

Factors of 26 = 1, 2, 13, 26

Factors of 39 = 1, 3, 13, 39

Factors of 52 = 1, 2, 4, 13, 26, 52

The highest common factor for the 3 numbers is 13.

Thus,in total, the highest common factor for the algebraic expression is 13r².

Finally, we have;

Therefore, the coefficient of determination for regression model is 0.8209, rounded to four decimal places.

The coefficient of determination, R-squared (r²), is a measure of how well a linear regression model fits the data. It tells us the proportion of the total variation in the response variable (y) that is explained by the linear regression model.

In order to calculate r², we first need to calculate the regression sum of squares (SSR) and the total sum of squares (SST). The regression sum of squares measures the amount of variation in the response variable that is explained by the regression model. The total sum of squares measures the total amount of variation in the response variable.

Once we have calculated SSR and SST, we can calculate r² as the ratio of SSR to SST. In this case, we are given the values of SSR and SST in the ANOVA table. We can calculate r² as:

r² = SSR/SST

= 24.5710256/29.93203039

= 0.8209 (rounded to four decimal places)

Therefore, the coefficient of determination, R-squared (r²), is 0.8209, which means that 82.09% of the total variation in the response variable is explained by the linear regression model. This is a relatively high value for r², which indicates that the model is a good fit for the data.

Answer:

First, we evaluate the amount that the portion has been multiplied by. We want to determine how many number 8's fit in to the number 24 because the bottom of the portion is 24.

The solution would be 3, because eight multiplied by 3 equals 24. Also because the bottom of the fraction has been multiplied by three, the top, known as the numerator, also needs to be multiplied by three. As a result, the top becomes 3 multiplied by 3, which equals 9. As a result, the portion is 9/24.
