Answer:

294

Step-by-step explanation:

Surface area is the total area of the bases

The cube shown has a side length of 7

Cubes have 6 bases, each being a square, and the area of a square can be calculated by squaring the side length.

7^2 = 49

So the area of 1 base is 49

If we want to find the area of all the bases we multiply the area of 1 base by 6 ( because there are 6 bases )

42 * 6 = 294

The area of all of the bases is 294 so the surface area is 294

Given:

Darcy harvests \(8\dfrac{3}{4}\) acres of corn every \(\dfrac{5}{6}\) of an hour.

Darcy harvests corn at a constant rate.

To find:

How many acres does she harvest per hour?

Solution:

We have,

Acres harvest in \(\dfrac{5}{6}\) of an hours = \(8\dfrac{3}{4}\)

Acres harvest in 1 hour = \(8\dfrac{3}{4}\times \dfrac{6}{5}\)

                                      = \(\dfrac{32+3}{4}\times \dfrac{6}{5}\)

                                      = \(\dfrac{35}{4}\times \dfrac{6}{5}\)

Cancel out the common factors, we get

Acres harvest in 1 hour = \(\dfrac{7}{2}\times \dfrac{3}{1}\)

                                      = \(\dfrac{21}{2}\)

                                      = \(10\dfrac{1}{2}\)

Therefore, she can harvest \(10\dfrac{1}{2}\) acres of corn per hour.

Answer: 6x + 2y

Step-by-step explanation:

To find a fundamental set of real solutions for the differential equation y' = Ay, where A is a 2x2 real matrix with an eigenvalue of 1 + 3i and corresponding eigenvector v, we need to determine the real solutions.

Given:

A = [[a, b], [c, d]] is a 2x2 real matrix

Eigenvalue: λ = 1 + 3i

Eigenvector: v₁ = [0, -4]ᵀ

Step 1: Eigenvalues

The characteristic equation is:

det(A - λI) = 0

Substituting the given eigenvalue λ = 1 + 3i into the characteristic equation, we have:

det(A - (1 + 3i)I) = 0

Substituting the values of A and I:

det([[a, b], [c, d]] - [[1 + 3i, 0], [0, 1 + 3i]]) = 0

Expanding and simplifying:

(a - (1 + 3i))(d - (1 + 3i)) - bc = 0

ad - (1 + 3i)d - (1 + 3i)a + (1 + 3i)^2 - bc = 0

ad - ad - 3id - (1 + 3i)a + (1 + 3i)^2 - bc = 0

(1 + 3i)^2 - (1 + 3i)a - 3id - bc = 0

(1 + 6i - 9 - 9i) - (a + 3i - 3a - 9i) - 3id - bc = 0

(-8 - 3i) - (2a - 6i) - 3id - bc = 0

-8 - 3i - 2a + 6i - 3id - bc = 0

To satisfy the equation, the real and imaginary parts must be equal separately:

-8 - 2a - bc = 0  (real part)

-3 - 3a - d = 0    (imaginary part)

Step 2: Eigenvectors

Now, let's find the corresponding eigenvectors for the eigenvalue λ = 1 + 3i.

For λ = 1 + 3i, substitute it into the equation:

-8 - 2a - bc = 0

-3 - 3a - d = 0

We can choose a = 0 and b = -4 to simplify the equations:

-8 - 2(0) - (-4)c = 0

-3 - 3(0) - d = 0

Simplifying further, we have:

-8 + 4c = 0

-3 - d = 0

Solve these equations to find the values of c and d:

c = 2

d = -3

Therefore, the eigenvector corresponding to the eigenvalue λ = 1 + 3i is:

v₁ = [0, -4]ᵀ

Step 3: Fundamental Set of Solutions

To find the fundamental set of solutions, we can use the eigenvalue and eigenvector we found.

The general solution for the system of differential equations y' = Ay is given by:

y(t) = c₁e^(λ₁t)v₁

Substituting the given eigenvalue and eigenvector:

y(t) = c₁e^((1 + 3i)t)[0, -4]ᵀ

To obtain a real-valued solution, we can take the real part of the above expression:

y(t) = Re(c₁e^((1 + 3

i)t)[0, -4]ᵀ)

Using Euler's formula, e^(ix) = cos(x) + isin(x):

y(t) = Re(c₁[cos((1 + 3i)t) + isin((1 + 3i)t)][0, -4]ᵀ)

Expanding and simplifying:

y(t) = Re(c₁[0, -4cos((1 + 3i)t) - 4isin((1 + 3i)t)]ᵀ)

The real part of a complex number is obtained by taking the real part of each component:

y(t) = [0, -4Re(c₁cos((1 + 3i)t) - 4Re(c₁isin((1 + 3i)t))]ᵀ

Since we want a fundamental set of solutions consisting entirely of real solutions, we can choose c₁ to be a real constant. Let's denote it as c₁ = k, where k is a real number.

The final fundamental set of solutions is:

y(t) = [0, -4kcos((1 + 3i)t)]ᵀ, where k is a real constant.

The derivative of the vector function r(t) = ⟨6t, t^2, 1/9t^3⟩ is r'(t) = ⟨6, 2t, t^2⟩.

To find the derivative of a vector function, we differentiate each component of the vector with respect to the variable, which in this case is t. Taking the derivative of each component of r(t), we get:

The derivative of 6t with respect to t is 6, as the derivative of a constant multiple of t is the constant itself.

The derivative of t^2 with respect to t is 2t, as we apply the power rule which states that the derivative of t^n is n*t^(n-1).

The derivative of (1/9t^3) with respect to t is (1/9) * (3t^2) = t^2/3, as we apply the power rule and multiply by the constant factor.

Combining the derivatives of each component, we obtain r'(t) = ⟨6, 2t, t^2⟩. This represents the derivative vector of the original vector function r(t).

Borrowers can make more accurate comparisons between different loan options and understand the overall cost they will incur over the life of the loan.

In the given scenario, there are two banks offering 20-year, $210,000 mortgages at 4.4 percent interest. The banks charge a $3,100 loan application fee. However, there is a difference between the banks regarding the refundability of the application fee.

Insecurity Bank and Trust: This bank charges a $3,100 loan application fee, which is refundable if the loan application is denied. In this case, the fee is considered part of the loan rather than a separate fee.

I. M. Greedy and Sons Mortgage Bank: This bank also charges a $3,100 loan application fee, but it is nonrefundable, meaning it will not be returned if the loan application is rejected.

The disclosure law requires that any fees that will be refunded if the applicant is rejected must be included in calculating the Annual Percentage Rate (APR). This is because these fees are considered part of the loan amount and have an impact on the overall cost of borrowing.

On the other hand, nonrefundable fees like the one charged by I. M. Greedy and Sons Mortgage Bank are not required to be included in the APR calculation. This is because these fees are treated as separate costs that are not directly part of the loan.

When comparing mortgage offers and determining the true cost of borrowing, it is important to consider not only the interest rate but also any associated fees. By including refundable fees in the APR calculation, borrowers can make more accurate comparisons between different loan options and understand the overall cost they will incur over the life of the loan.

Answer:

76 degrees.

Step-by-step explanation:

Let as consider O is the center of the circle . So from the figure it is clear that

\(\angle AOB=44^{\circ}\)

\(\angle COD=118^{\circ}\)

By central angle theorem, central angle subtended by an arc is twice of inscribed angle of the same arc.

We know that, \(\angle BAD=97^{\circ}\) and angle BOD is the central angle subtended by arc BD.

\(\angle BOD=2\times \angle BAD\)

\(\angle BOD=2\times 97^{\circ}\)

\(\angle BOD=194^{\circ}\)

Now,

\(\angle BOD=\angle BOC+\angle COD\)

\(194^{\circ}=\angle BOC+118^{\circ}\)

\(194^{\circ}-118^{\circ}=\angle BOC\)

\(76^{\circ}=\angle BOC\)

\(m(arc(BC))=76^{\circ}\)

Therefore, the measure of arc BC is 76 degrees.

b) 2370 Grams grams of cake in white colour.

c) The total cost of the cake is Dhs 285.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Anoop measured the weight of a cake on a weighing scale as 4kg 740 g.

a) He uses ¾ of the cake for his birthday party.

According to the null hypothesis, all group population means are equal. Because it is assumed that the populations are normal and that they have similar variances, the equal means hypothesis indicates that the populations have the same normal distribution. All groups are samples from populations with the same normal distribution, according to the null hypothesis.
