Emerson wants to fence in a rectangle play area for his dog. He decides to make the length 2 feet longer than the width. He has 32 feet of fencing to use for this project and will use it all. What will the dimensions of the dog’s play area be?
Answers
If Emerson wants to fence a rectangular play area for his dog where he decides to make the length of the fence, 2feet more than the width, and he uses the complete 32feet fencing he had with himself, for this project, then the dimensions of the play area are 9ft in length and 7ft in width.
As per the question statement, Emerson wants to fence a rectangular play area for his dog and he decides to make the length of the fence, 2feet more than the width, for which, he uses the complete 32feet fencing he had with himself.
We are required to calculate the dimensions the play area from the above-mentioned data.
To solve this question, we need to know the formula to calculate the perimeter of rectangle which goes as [p = 2(l + b)]
Where, "p" is the perimeter of the rectangle, "l" is the length and "b" is the breadth of the rectangle.
Here given that, length of the fence will be 2feet more than width of the same. So, let us assume that width of the fence is "x" ft, and the length of the fence should be (x + 2)ft.
Also since, Emerson uses the complete 32feet fencing he had with himself, the perimeter of the play-area will be 32ft.
Substituting our assumptions in the above mentioned formula to calculate the perimeter of rectangle, we get, [32 = 2{x + (x + 2)}], which is a linear equation. Therefore, solving this equation for x, we will obtain our desired answer.
[32 = 2{x + (x + 2)}]
Or, [32 = 2(x + x + 2)]
Or, [32 = 2(2x + 2)]
Or, (32 = 4x + 4)
Or (4x = 32 - 4)
Or, (4x = 28)
Or, [x = (28/4)]
Or, (x = 7).
Therefore, (x + 2) = (7 + 2) = 9ft.

The matrix X is [tex]X = A^{-1} B[/tex]
What are invertible matrix?
A square matrix is invertible if and only if the determinant is not equal to zero. A n × n matrix is only invertible if the determinant of the matrix is not zero and has inverse. If the determinant is zero, then the matrix is not invertible and has no inverse.
Given that the two matrix A, B are invertible, therefore the inverse of the matrix exists.

Korey’s comic book store has been up and running for 4 years. Korey feels that his store has been successful and is considering moving to a larger property to allow for greater inventory and customer opportunities in his business. He would like investors to cover the cost of his expansion. The profits of Korey’s comic book store for its first four years are outlined below. According to this information, what would be the best estimate for Korey to quote as expected profits in the next year in his new business plan? Year Net Profits 1 $14,250.00 2 $15,390.00 3 $16,621.20 4 $17,950.90 5 a. $20,550.19 b. $19,090.90 c. $19,280.60 d. $19,386.97
Answers
The next year's expected profit to quote is $19,386.97
Given,
Net profit for 1st year = $14,250
Net profit for 2nd year = $15,390
Net profit for 3rd year = $16,621.21
Net profit for 4th year = $17,950.90
We have to find the expected profit in the next year.
For that, first we have to find the profit percentage of 4 years.
Profit % for 1st year =( 15,390 - 14,250 )/14250 × 100 = 0.08 × 100 = 8%
Profit % for 2nd year =( 16,621.21 - 15,390 )/15,390 × 100 = 0.08 × 100 = 8%
Profit % for 3rd year =( 17,950.90 - 16,621.21)/16,621.21 × 100 = 0.08 × 100 = 8%
So the profit percentage is consistent for the years.
Then we can find next years profit by;
Net profit for 4th year × 1.08 = 17,950.90 × 1.08 = 19,386.97
That is,
The next year's expected profit to quote is $19,386.97

D

Answers
The equivalent expression to 45÷(2-x) is 45/(2-x).
According to the question,
We have the following expression:
45÷(2-x)
Or in other words, it can be said that 45 is divided by (2-x).
Now, when we are finding the equivalent expression of any expression for that matter then the final expression after solving any expression should be equal to the original one.
For example, the equivalent expression for 3/5 is 6/10 because when we divide the second fraction by we will get 3/5.
Now, in this case, the equivalent expression will be:
45/(2-x)
Because the fraction also means division.
Hence, the correct option is A.

What will the new demensions of the rectangle below be after a dilation within scale factor of 9\4
Answers
Answer
The new dimensions of the rectangle after dilation by scale factor of (9/4) include
New length = 72 feet
New width = 18 feet
Explanation
The relationship between new length, original length and scale factor of dilation is given as
New length = (Original length) × (Scale factor)
For this question,
Scale factor = (9/4)
Original length = 32 feet
New length = (Original length) × (Scale factor)
New length = 32 × (9/4) = 72 feet
New width = (Original width) × (Scale factor)
Original width = 8 feet
Scale factor = (9/4)
New width = (Original width) × (Scale factor)
New width = 8 × (9/4) = 18 feet

Let the following variables represent the velocities of the plane and the wind:
[tex]\begin{gathered} \text{Velocity of the plane: }v_p \\ \text{Velocity of the wind: }v_w \end{gathered}[/tex]When the plane travels with the wind, the total velocity is the sum of both velocities. When the plane travels against the wind, the resulting velocity will be the difference of both velocities.
When the plane travels with the wind, the following condition is satisfied:
[tex]v_p+v_w=\frac{880\text{ miles}}{11\text{ hours}}[/tex]When the plane travels against the wind, the following condition is satisfied:
[tex]v_p-v_w=\frac{880\text{ miles}}{20\text{ hours}}[/tex]This is a 2x2 system of equations. To solve it by the elimination method, add both equations:
[tex](v_p+v_w)+(v_p-v_w)=\frac{880\text{ miles}}{11\text{ hours}}+\frac{880\text{ miles}}{20\text{ hours}}[/tex][tex]\begin{gathered} \Rightarrow v_p+v_w+v_p-v_w=\frac{880\text{ miles}}{\text{hour}}(\frac{1}{11}+\frac{1}{20}) \\ \Rightarrow2v_p=\frac{880\text{ miles}}{\text{ hour}}(\frac{31}{220}) \\ \Rightarrow2v_p=124\cdot\frac{\text{miles}}{\text{hour}} \\ \Rightarrow v_p=62\cdot\frac{\text{ miles}}{\text{ hour}} \end{gathered}[/tex]Solve for the velocity of the wind from the first equation:

C. an=21+ (n-1)6
D. an= (-9) + (n-1)6
Answers
The explicit formula for this sequence exists as = (-9) + (n-1)6
Explain about the explicit formula ?We can use an explicit formula, as previously discussed, to determine the nth term in a series. The simplest meaning of explicit is precise or unambiguous. The reason the formula is explicit is that, if properly used, it can be used to find the nth term.
An arithmetic sequence can be expressed explicitly as a = a + (n - 1)d, and each term of the sequence can be computed without knowledge of the other parts. The nth term of an arithmetic, geometric, or harmonic series is usually the explicit formula.
Given: -9, -3, 3, 9, 15.
Because it is an arithmetic series, the supplied sequence.
Therefore, there is no difference between two consecutive terms.
For example, 3-(-3)=6 and (-3)-(-9)=6.
The nth term is now equal to a+(n-1)d.
as, a=-9
So, = -9+(n-1)6
= -9+6n-6
= 6n-15
so that =-9+(n-1)6.
