The domain of the function f(x, y) is the set of all (x, y) values that satisfy the inequality y < 3 - 3x.

To determine the domain, we need to consider the restrictions on the variables x and y that would result in a valid logarithmic function. In this case, the natural logarithm ln is defined only for positive arguments.

For ln(3 - 3x - y) to be defined, the expression inside the logarithm (3 - 3x - y) must be greater than zero.

Thus, the domain of the function is the set of all (x, y) values that satisfy the inequality 3 - 3x - y > 0. This inequality can be rearranged as y < 3 - 3x.

Therefore, the domain of the function f(x, y) is the set of all (x, y) values that satisfy the inequality y < 3 - 3x.

Step-by-step explanation:

The width of the rectangle = x

Therefore the length of the rectangle = 2x, as it is twice its width

We know that the perimeter of a rectangle = 2 × （length + width）

So since the perimeter equals to 30, then we can form the equation:

                                      2×(2x+x) = 30

                                          2×(3x) = 30

                                                6x = 30

                                                   x = 5

width of the rectangle = x = 5

length of the rectangle = 2x = 2×5 = 10

If there is an unit which is in the question, remember to add it to the end of the answer. As you have not written any units in the posted question, I will leave it as it is.

Hope this helps :)

Step-by-step explanation:

given,

perimeter (p)=30

let the length be x and breadth be x÷2 (as the length is twice of its breadth)

now, perimeter (p)=30

or, 2(l+b)=30

or, 2(x+x/2)=30

or, 6x/2=30

or, 3x=30

therefore the value of x is 10.

the dimensions are,

so, length (l)=10 breadth (b) =10/2=5...ans

To calculate the volume left unoccupied in the cylinder, we need to subtract the volume of the ball from the volume of the cylinder.

The volume of the cylinder can be calculated using the formula:

V_cylinder = π * r^2 * h

where π is the mathematical constant (approximated as 3.14), r is the radius of the cylinder, and h is the height of the cylinder.

Given that the cylinder has a height of 8 inches and a radius of 3 inches, we can calculate its volume:

V_cylinder = 3.14 * 3^2 * 8

V_cylinder = 3.14 * 9 * 8

V_cylinder = 226.08 cubic inches

Next, let's calculate the volume of the ball. The formula for the volume of a sphere is:

V_sphere = (4/3) * π * r^3

where r is the radius of the sphere.

Given that the ball has a diameter of 5 inches (radius = 2.5 inches), we can calculate its volume:

V_sphere = (4/3) * 3.14 * 2.5^3

V_sphere = (4/3) * 3.14 * 15.625

V_sphere = 65.45 cubic inches (rounded to two decimal places)

Volume left unoccupied = V_cylinder - V_sphere

Volume left unoccupied = 226.08 - 65.45

Volume left unoccupied = 160.63 cubic inches (rounded to two decimal places)

Therefore, approximately 160.63 cubic inches of volume is left unoccupied in the cylinder.

To estimate the mean EPA combined city and highway mileage, the automaker conducted EPA mileage tests on a random sample of 35 midsize cars. The sample mean is 24, and the population standard deviation is 1.2. The task is to calculate the 70% confidence interval for the population mean.

To calculate the confidence interval, we can use the formula:

Confidence Interval = Sample Mean ± (Critical Value) * (Standard Deviation / √(Sample Size))

First, we need to determine the critical value associated with a 70% confidence level. The critical value can be found using a standard normal distribution or a t-distribution, depending on the sample size and whether the population standard deviation is known.

Since the sample size is relatively large (n = 35), we can use the standard normal distribution. The critical value for a 70% confidence level corresponds to a z-score of ±1.036.

Next, we calculate the margin of error:

Margin of Error = (Critical Value) * (Standard Deviation / √(Sample Size)) = 1.036 * (1.2 / √35) ≈ 0.380

Finally, we can calculate the lower and upper bounds of the confidence interval:

Lower Bound = Sample Mean - Margin of Error = 24 - 0.380 ≈ 23.62

Upper Bound = Sample Mean + Margin of Error = 24 + 0.380 ≈ 24.38

Therefore, the 70% confidence interval for the mean EPA combined city and highway mileage is approximately 23.62 to 24.38.

let c = 10 cm  ,  b = 8 cm

plug in values

a² + 8² = 10²

a² = 10² - 8²

a = \(\sqrt{10^2 - 8^2}\)

a = 6 cm

Answer:

6 cm

Step-by-step explanation:

We can use the Pythagorean Theorem to find the length of the missing side.

The Pythagorean Theorem states that the hypotenuse of a right triangle will be \(a^2 + b^2\), where a and b are the leg lengths.

Together, we get the formula \(a^2 + b^2 = c^2\).

Since we know the hypotenuse (c) and one of the sides (let's say a), we can find the missing side (b) by substituting inside the equation.

\(8^2 + b^2 = 10^2\\\\64 + b^2 = 100\\\\b^2 = 100-64\\\\b^2 = 36\\\\b = \sqrt{36}\\\\b=6\)

So the missing side is 6 cm long.

When Omar does not have a common factor while factoring a polynomial, he should consider regrouping terms, factoring out a common factor, or adjusting signs to simplify the expression. The absence of a common factor does not necessarily mean the polynomial is prime.

If Omar noticed that he does not have a common factor when factoring a polynomial, there are a few possible next steps to consider. It is important to note that the absence of a common factor does not necessarily mean that the polynomial is prime.

One option for Omar is to go back and regroup the terms in step 1, as (3x³ – 15x²) – (4x + 20). By rearranging the terms, he may be able to identify a common factor or a different factorization approach.

Another possibility is for Omar to factor out a common factor from the first expression in step 2. He can examine the terms in the expression and determine if there is a factor that can be pulled out.

It is also worth considering whether Omar needs to factor out a negative from one of the groups so that the binomials become the same. This step can help simplify the expression and make the factoring process easier.

Overall, Omar should explore different factorization strategies, regroup terms if necessary, and look for common factors or patterns to continue factoring the polynomial. The absence of a common factor does not necessarily imply that the polynomial is prime.

The future value (A) is approximately 5610.2 for the given investment and annu $4000 for 5 years at 7% compounded annually

To find the compound amount and compound interest rate for the given investment, we can use the formula for compound interest:

(a) The compound amount in the account after 5 years can be calculated using the formula:

A = P(1 + r/n)^(nt)

Where A is the compound amount, P is the principal (initial investment), r is the interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

Given that the principal (P) is $4000, the interest rate ® is 7%, and the interest is compounded annually (n = 1), and the investment is for 5 years (t = 5), we can plug these values into the formula:

A = 4000(1 + 0.07/1)^(1*5)

A = 4000(1 + 0.07/1)^(1*5)

= 4000(1 + 0.07)^(5)

= 4000(1.07)^(5)

≈ 4000(1.402551)

≈ 5610.20

Therefore, the future value (A) is approximately 5610.2

Calculating this expression will give us the compound amount after 5 years.

(b) The compound interest earned can be calculated by subtracting the principal from the compound amount:

Compound interest = Compound amount – Principa

This will give us the total interest earned over the 5-year period.

By evaluating the expressions in (a) and (b), we can determine the compound amount and the compound interest earned for the given investment.
