Answer:
The expression of the area of rectangle ABCD as simplified polynomial will be:
[tex]A=16x^2-8x[/tex]
Hence, the 2nd option is correct.
Step-by-step explanation:
As we know that the area of a rectangle can be obtained by multiplying the length by the width.
i.e.
[tex]A=l\times w[/tex]
Given
The length of a rectangle ABCD = [tex]l[/tex] = [tex](x+5) + (3x) + (4x-9)[/tex]
The width of a rectangle = [tex]w[/tex] = [tex]2x[/tex]
so the expression of the area of rectangle ABCD as simplified polynomial will be:
[tex]A=l\times w[/tex]
[tex]A=\left[\left(x+5\right)\:+\:\left(3x\right)\:+\:\left(4x-9\right)\right]\:\times \left[2x\right][/tex]
[tex]=\left(\left(x+5\right)+\left(3x\right)+\left(4x-9\right)\right)\left(2x\right)[/tex]
[tex]=\left(x+5+3x+4x-9\right)\times \:2x[/tex]
[tex]=2x\left(8x-4\right)[/tex]
[tex]=16x^2-8x[/tex]
Therefore, the expression of the area of rectangle ABCD as simplified polynomial will be:
[tex]A=16x^2-8x[/tex]
Hence, the 2nd option is correct.

Is it possible for the absolute value function to have negative values?
Answer:
Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number's sign: if it's positive, it's equal to the number: |9|=9. If the number is negative, then the absolute value is its opposite: |-9|=9.

Part A
Katie just opened a checking account at the bank. Within the first month, she deposited three checks for $21.68, $42.09, and $65.44. She withdrew $4.64 for new pencils, $23.11 for earbuds, and $9.78 for movies from her account in the same month.
Write Katie’s withdrawals as negative rational numbers and her deposits as positive rational numbers.
Part B
Order the rational numbers from least to greatest and explain your reasoning.
Part C
At the beginning of the month Katie’s balance was $128. What was her balance at the end of the month after all of her deposits and withdrawals? You must show your work, no credit will be given for just an answer.
Answer:
(a) The deposits to be 21.68, 42.09, and 65.44 and the withdrawals to be -4.64, -23.11 and -9.78
(b) [tex]Order: -23.11, -9.78, -4.64, 21.68, 42.09, 65.44[/tex]
(c) [tex]Final\ Balance = \$219.68[/tex]
Step-by-step explanation:
Given
Deposits: $21.68, $42.09, and $65.44
Withdrawals: $4.64, $23.11 and $9.78
Solving (a): Write out the deposits as positive and the withdrawals as negatives
From (given) above, we have
The deposits to be 21.68, 42.09, and 65.44
and
The withdrawals to be -4.64, -23.11 and -9.78
Solving (b): Order from least to greatest.
Since the withdrawals are negative, the arrangement will start from there because negative numbers are lesser than positives.
Arranging the withdrawals from least to greatest, we have:
-23.11, -9.78, -4.64.
Arranging the deposits from least to greatest, we have:
21.68, 42.09, 65.44
Combine both together;
[tex]Order: -23.11, -9.78, -4.64, 21.68, 42.09, 65.44[/tex]
Solving (c):
[tex]Initial\ Balance = \$128[/tex]
Required
Determine the final balance
First we need to get the total deposits:
[tex]Total\ Deposits = \$21.68 + \$42.09 + \$65.44[/tex]
[tex]Total\ Deposits = \$129.21[/tex]
Next, we determine the total withdrawals:
[tex]Total\ Withdrawals = \$4.64 + \$23.11 + \$9.78[/tex]
[tex]Total\ Withdrawals = \$37.53[/tex]
The final balance is then calculated as:
[tex]Final\ Balance = Initial\ Balance + Total\ Deposits - Total\ Withdrawals[/tex]
[tex]Final\ Balance = \$128 + \$129.21 - \$37.53[/tex]
[tex]Final\ Balance = \$219.68[/tex]

Step-by-step explanation:
a.
P(N=0) = 10C0(0.15)0(0.85)10 = 0.19687
b.
P(N > 1) = 1 - P(N=0) - P(N=1)
P(N=0) = 20C0(0.15)0(0.85)20 = 0.03876
P(N=1) = 20C1(0.15)1(0.85)19 = 0.1368
P(N > 1) = 1 - 0.03876 - 0.1368 = 0.82444
Dose the table represent a function?
Answer:
You can also use tables to represent functions. Instead of using two ovals with circles, a table organizes the input and output values with columns. ... Remember, a function can only assign an input value to one output value. If you see the same x-value with more than one y-value, the table does not represent a function. so yeah it does represent a function.

Read this entry from a blog about service dogs. Lexie, an eight-month-old black Labrador retriever, is sleeping quietly at my feet. I can’t help but think that her soft, velvety ears and alert brown eyes would make her the perfect "doggie model" for pet magazines and pet store ads. However, Lexie will soon have a much more important job to do. In a few months, she will become the loyal companion and service dog for a young man who has been blind since birth. She will help him board public transportation, such as buses, subways, and trains, and she will help him safely cross busy intersections. Lexie will even help the young man avoid obstacles, such as high curbs and low overhangs. Like all dogs in our organization, Lexie has undergone months of specialized training to help a visually impaired person lead an active and independent life. Which statement about this blog is true? Its primary purpose is to persuade; its secondary purpose is to inform. Its primary purpose is to inform
Answer:

If x=-5+6i and y=3-2i , then which of the following is the value of the expression 4x-y?
Answer:
Expression = -23 + 26i
Step-by-step explanation:
Given the following data;
x = -5 + 6i
y = 3 - 2i
Expression = 4x - y
Substituting the values of "x" and "y" into the equation, we have
4(-5 + 6i) - (3 - 2i)
Expanding the bracket, we have;
Expression = -20 + 24i - 3 + 2i
Expression = -23 + 26i

Answer:
Step-by-step explanation:
A. when you multiply exponents with a common base you keep the base and add the exponents. In this case you would keep the 6 and add the -5 and 2 so the answer would be:
6^-3 which is not equivalent
B. You can distribute the exponent in to the parenthesis.
(1^5)/(6^2)^5
when you have an exponent to an exponent you mutliply. so the answer would be:
1^5/6^10
1^5 is always going to be 1 so you actually have:
1/6^10
when the exponent is on the bottom you can bring it to the top by making it negative, so the final answer for B is:
6^-10 which is equivalent
C. Same rules as B, multiply an exponent to an exponent.
6^(-5*2) = 6^-10 which is equivalent
D. When you are dividing exponents with a common base you subtract the top and bottom exponents. So in this case you have:
6^(-3-7) = 6^-10 which is equivalent
E. Using the rules from eariler the numerator can be simplified by adding the exponents.
6^5 * 6^-3 = 6^(5-3) = 6^2
which leaves you with:
6^2/6^-8
From there you can either bring the 6^-8 to the numberator to make it positive which simplifies to:
6^2 * 6^8 = 6^(2+8) = 6^10 which is not equivalent
or you can subtract the top and bottom exponents:
6^2/6^-8 = 6^(2-(-8))
the double negative cancels to a positive and you getL
6^(2+8) = 6^10 which is not equivalent
so B, C, and D are equal to 6^-10

What is a fraction?A fraction is a part of a whole.
It is expressed as a quotient, in which the numerator is divided by the denominator.
Example: 2/3, 5/7, 1/3
We have,
2/5 ÷ 4
= (2/5) / 4
= 2 / (4 x 5 )
We cancel the common factor from the numerator and denominator.
= 2 / (2 x 2 x 5)
= 1 / (2 x 5)
= 1 / 10
We see that there is no common factor to be canceled out from the numerator and the denominator.
= 1/ 10 is our simplest form.
Thus the simplest form of 2/5 divided by 4 is 1/10.
