Part C: How does Part A demonstrate the closure property for the multiplication of polynomials?

Answers

Answer 1

The expression that represents the area of the rectangle is 6x²+29x+35.

Given that, a rectangle has sides measuring (2x + 5) units and (3x + 7) units.

What is the area of a rectangle?

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Part A:

Now, area = (2x+5)(3x+7)

= 2x(3x+7)+5(3x+7)

= 6x²+14x+15x+35

= 6x²+29x+35

So, the area of a rectangle is 6x²+29x+35

Part B:

A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.

Here, the degree of the expression 6x²+29x+35 is 2.

Part C:

Closure property of multiplication states that if any two real numbers a and b are multiplied, the product will be a real number as well.

Here, we obtained product of two binomials is trinomial

Therefore, the expression that represents the area of the rectangle is 6x²+29x+35.

Answer:

t^3 (4 ln(cos8t) - t tant)

Step-by-step explanation:

Using the Product Rule:

dy/dt = t^4 * d(ln(8cost) / dt + ln(8cost) * d(t^4)/dt

         = t^4 * 1/ (8cost) * (-8sint) + 4t^3 ln(8cost)

         = -8t^4 sint / 8 cost + 4t^3 ln(8cost)    

         = -t^4 tan t + 4t^3 ln(8cost)  

          = t^3 (4 ln(cos8t) - t tant)

Which systems of inequalities represents the number of apartments to be built

Answers

Given that:

- The office building contains 96,000 square feet of space.

- There will be at most 15 one-bedroom units with an area of 800 square feet. The rent of each unit will be $650.

- The remaining units have 1200 square feet of space.

- The remaining units will have two bedrooms. The rent for each unit will be $900.

Let be "x" the number of one-bedroom apartments and "y" the number of two-bedroom apartments.

• The words "at most 15 one-bedroom units" indicates that the number of these apartments will be less than or equal to 15 units:

[tex]x\leq15[/tex]

• You know that the remaining units are two-bedroom apartments. And the number of them is greater than or equal to zero. Then, you can set up the second inequality to represent this:

[tex]y\ge0[/tex]

• You know the area of each one-bedroom apartment, the area of each two-bedroom apartment, and the total area that the office building contains. The sum of the areas of the apartments must be less than or equal to the total area of the office building.

Then, the inequality that represents this is:

[tex]800x+1200y\leq96,000[/tex]

• Therefore, you can set up this System of Inequalities to represent that situation:

[tex]\begin{gathered} \begin{cases}x\leq15 \\ \\ y\ge0 \\ \\ 800x+1200y\leq96,000 \\ \end{cases} \\ \end{gathered}[/tex]

Answers

To change decimal or fraction to percent multiply them by 100

Example: 1/4 x 100% = 25%, 0.2 x 100% = 20%

Let us check the answer of the 3 students

Maggie wrote 75% = 3/5

Since

[tex]\frac{3}{5}\times100=\frac{300}{5}=60[/tex]

Then 3/5 = 60%, not 75%

Maggie is wrong

Bieber wrote 0.05 = 50%

Let us check

0.05 x 100% = 5%, not 50%

Bieber is wrong

Yung wrote 3/8 = 0.375

Let us check

[tex]\begin{gathered} \frac{3}{8}\times100=\frac{300}{8}=\frac{\frac{300}{2}}{\frac{8}{2}}=\frac{150}{4} \\ \frac{150}{4}=\frac{\frac{150}{2}}{\frac{4}{2}}=\frac{75}{2}=37.5 \end{gathered}[/tex]

g(x)= x^2 + 2hx) = 3x - 2Find (g+ h)(-3)

Answers

Given the following functions;

f(x) = x^2 + 2

g(x) = 3x - 2

(g+h)(x) = g(x)+h(x)

(g+h) = x^2 + 2 + 3x - 2

(g+h) = x^2+3x + 2-2

(g+h) = x^2 + 3x

To get (g+h) (-3), we will subtitute x = -3 into the resulting function as shown;

(g+h) (-3) = (-3)^2+3(-3)

(g+h) (-3) = 9 - 9

(g+h) (-3) = 0

Hence the value of the expression (g+h) (-3) is 0

The average American man consumes 9.6 grams of sodium each day. Suppose that the sodium consumption of American men is normally distributed with a standard deviation of 0.8 grams. Suppose an American man is randomly chosen. Let X = the amount of sodium consumed. Round all numeric answers to 4 decimal places where possible. a. What is the distribution of X? X - NO b. Find the probability that this American man consumes between 9.7 and 10.6 grams of sodium per day. C. The middle 10% of American men consume between what two weights of sodium? Low: High:

Answers

The variable of interest is

X: sodium consumption of an American male.

a) This variable is known to be normally distributed and has a mean value of μ=9.6grams with a standard deviation of δ=0.8gr

Any normal distribution has a mean = μ and the variance is δ², symbolically:

X~N(μ ,δ²)

For this distribution, we have established that the mean is μ=9.6grams and the variance is the square of the standard deviation so that: δ² =(0.8gr)²=0.64gr²

Then the distribution for this variable can be symbolized as:

X~N(9.6,0.64)

b. You have to find the probability that one American man chosen at random consumes between 9.7 and 10.6gr of sodium per day, symbolically:

[tex]P(9.7\leq X\leq10.6)[/tex]

The probabilities under the normal distribution are accumulated probabilities. To determine the probability inside this interval you have to subtract the accumulated probability until X≤9.7 from the probability accumulated probability until X≤10.6:

[tex]P(X\leq10.6)-P(x\leq9.7)[/tex]

Now to determine these probabilities, we have to work under the standard normal distribution. This distribution is derived from the normal distribution. If you consider a random variable X with normal distribution, mean μ and variance δ², and you calculate the difference between the variable and ist means and divide the result by the standard deviation, the variable Z =(X-μ)/δ ~N(0;1) is determined.

The standard normal distribution is tabulated. Any value of any random variable X with normal distribution can be "converted" by subtracting the variable from its mean and dividing it by its standard deviation.

So to calculate each of the asked probabilities, you have to first, "transform" the value of the variable to a value of the standard normal distribution Z, then you use the standard normal tables to reach the corresponding probability.

[tex]P(X\leq10.6)=P(Z\leq\frac{10.6-9.6}{0.8})=P(Z\leq1.25)[/tex][tex]P(X\leq9.7)=P(Z\leq\frac{9.7-9.6}{0.8})P(Z\leq0.125)[/tex]

So we have to find the probability between the Z-values 1.25 and 0.125

[tex]P(Z\leq1.25)-P(Z\leq0.125)[/tex]

Using the table of the standard normal tables, or Z-tables, you can determine the accumulated probabilities:

[tex]P(Z\leq1.25)=0.894[/tex][tex]P(Z\leq0.125)=0.550[/tex]

And calculate their difference as follows:

[tex]0.894-0.550=0.344[/tex]

The probability that an American man selected at random consumes between 10.6 and 9.7 grams of sodium per day is 0.344

c. You have to determine the two sodium intake values ​​between which the middle 10% of American men fall. If "a" and "b" represent the values we have to determine, between them you will find 10% of the distribution. The fact that is the middle 10% indicates that the distance between both values to the center of the distribution is equal, so 10% of the distribution will be between both values and the rest 90% will be equally distributed in two tails "outside" the interval [a;b]

Under the standard normal distribution, the probability accumulated until the first value "a" is 0.45, so that:

[tex]P(Z\leq a)=0.45[/tex]

And the accumulated probability until "b" is 0.45+0.10=0.55, symbolically:

[tex]P(Z\leq b)=0.55[/tex]

The next step is to determine the values under the standard normal distribution that accumulate 0.45 and 0.55 of probability. You have to use the Z-tables to determine both values:

The value that accumulates 0.45 of probability is Z=-0.126

To translate this value to its corresponding value of the variable of interest you have to use the standard normal formula:

[tex]a=\frac{X-\mu}{\sigma}[/tex]

You have to write this expression for X

[tex]\begin{gathered} a\cdot\sigma=X-\mu \\ (a\cdot\sigma)+\mu=X \end{gathered}[/tex]

Replace the expression with a=-0.126, μ=9.6gr, and δ=0.8gr

[tex]\begin{gathered} X=(a\cdot\sigma)+\mu \\ X=(-0.126\cdot0.8)+9.6 \\ X=-0.1008+9.6 \\ X=9.499 \\ X\approx9.5gr \end{gathered}[/tex]

The value of Z that accumulates 0.55 of probability is 0.126, as before, you have to translate this Z-value into a value of the variable of interest, to do so you have to use the formula of the standard normal distribution and "reverse" the standardization to reach the corresponding value of x:

[tex]\begin{gathered} b=\frac{X-\mu}{\sigma} \\ b\cdot\sigma=X-\mu \\ (b\cdot\sigma)+\mu=X \end{gathered}[/tex]

Replace the expression with b=0.126, μ=9.6gr, and δ=0.8gr and calculate the value of X:

[tex]\begin{gathered} X=(b\cdot\sigma)+\mu \\ X=(0.126\cdot0.8)+9.6 \\ X=0.1008+9.6 \\ X=9.7008 \\ X\approx9.7gr \end{gathered}[/tex]

The values of sodium intake between which the middle 10% of American men fall are 9.5 and 9.7gr.

How do I find the linear equation for this? (y=mx+b)

Answers

Okay, here we have this:

Considering the provided table, we are going to find the corresponding linear equation, so we obtain the following:

To do this we will start using the information in the slope formula, then we have:

m=(y2-y1)/(x2-x1)

m=(190-(-30))/(19-9)

m=220/10

m=22

Now, let's find the y-intercept (b) using the point (9, -30):

y=mx+b

-30=(22)9+b

-30=198+b

b=-30-198

b=-228

Jeff has a job at baseball park selling bags of peanuts .he get paid $12 a game and 1.75 per bag of peanuts they sell .how many bags if peanuts does he need to sell in order to earn $54 in one

Answers

Let x be the number of peanut bags Jeff sells. Since he earns $1.75 per bag the total amount he earns for selling x bags is:

[tex]1.75x[/tex]

Now, to this we have to add the $12 he gets paid, then the total amount he earns is:

[tex]1.75x+12[/tex]

To find out how many bags he has to sell to earn $52 we equate the expression above with the amount and solve for x:

[tex]\begin{gathered} 1.75x+12=54 \\ 1.75x=54-12 \\ 1.75x=42 \\ x=\frac{42}{1.75} \\ x=24 \end{gathered}[/tex]

Pats normal pulse rate is 80 beats minute. How many times does it beat in 3/4 of a minute?

Answers

The number of times that pat pulse rate maintains the given ratio in 3/4 of a minute is 60 times.

What are the ratio and proportion?

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

For example, a/b, where a will be the numerator and b will be the denominator.

As per the given,

Pat's normal pulse rate is 80 beats per minute.

So, 80 beats → 1 minute

Multiply both sides by 3/4

80 × 3/4 beats  → 1 × 3/4  minute

(3/4) minute → 60 beats.

Hence "The number of times that pat pulse rate maintains the given ratio in 3/4 of a minute is 60 times".

Explanation

If the initial and terminal points of a vector are given, the vector itself is obtained, per coordinate, by doing a terminal point coordinate minus initial point coordinate.

u = [(5 - 15), (4 - 22)]

u = (-10, -18)

Then, we are told that vector v points in the opposite direction as that of vector u and its magnitude is twice that of vector u too.

In mathematical terms,

v = -2u

v = -2 (-10, -18)

A. Determine the slope intercept equation of each line given two points on the line 1. (1, -3) and (-2, 6)

Answers

ANSWER

y = -3x

EXPLANATION

We have to determine the slope-intercept form of the equation of the line.

The slope-intercept form of a linear equation is given as:

y = mx + c

where m = slope

c = y intercept

First, we have to find the slope:

[tex]m\text{ = }\frac{y2\text{ - y1}}{x2\text{ - x1}}[/tex]

where (x1, y1) and (x2, y2) are two points the line passes through.

Therefore:

[tex]\begin{gathered} m\text{ = }\frac{6-(-3)}{-2-1}=\frac{6+3}{-3}=\frac{9}{-3} \\ m=-3 \end{gathered}[/tex]

Now, we have to use the point-slope method to find the equation:

y - y1 = m(x - x1)

=> y - (-3) = -3(x - 1)

y + 3 = -3x + 3

y = -3x + 3 - 3

y = -3x

That is the slope intercept form of the equation.

h = (1 + 1/3) × w

The volume becomes;

V' = l × (1 + 1/3) × w × (1 - 1/3) × w = l•w²•(1²-1/3²)

V' = l•w²•(8/9)

The amount by which the volume increased, dV = 12 yd³

Which gives;

l•w²•(8/9) = l•w•h - 12 = l•w² - 12

l•w²•(8/9) - l•w² + 12 = 0

l•w²•(8/9) - l•w² + 12 = 0

l•w²/9 = 12

V = l•w² = 12 × 9 = 108

The correct volume of the prism is 108 cubic yards

1. Which expression is equivalent to 2 x (5 x 4)?a. 2+ (5 x 4)b. (2 x 5) x 4c. (2 x 5) x 4d. (5 x 4) x (2 X4)

Answers

We are given the following expression

[tex]2\times(5\times4)[/tex]

Recall the associative property of multiplication

[tex]a\times(b\times c)=(a\times b)\times c[/tex]

The associative property of multiplication says that when you multiply numbers, you can group the numbers in any order and still you will get the same result.

So, if we apply this property to the given expression then it becomes

[tex]2\times(5\times4)=(2\times5)\times4[/tex]

Therefore, the following expression is equivalent to the given expression.

[tex](2\times5)\times4[/tex]

A production applies several layers of a clear acrylic coat to outdoor furniture to help protect it from the weather. If each protective coat is 2/27 inch thick, how many applications will be needed to build up 2/3 inch of clear finish.

Answers

We know that

• Each protective coat is 2/27 inches thick.

,

• We need to fill 2/3 inches of this protective coat.

To solve this problem, we need to know the total number of the application needed to fill 2/3 inches. We can form the following expression

[tex]\frac{2}{27}x=\frac{2}{3}[/tex]

We solve for x

[tex]x=\frac{2\cdot27}{3\cdot2}=\frac{27}{3}=9[/tex]Therefore, we need 9 applications in total.

By algebra properties, the sum of four mixed numbers is equal to the mixed number [tex]8\,\frac{37}{40}[/tex].

How to simplify a sum of mixed numbers

In this problem we find a sum of four mixed numbers. The simplification process consists in transforming each mixed number into a fraction and apply algebra properties. Then,

[tex]9 \,\frac{1}{2}[/tex] = 9 + 1 / 2 = 18 / 2 + 1 / 2 = 19 / 2

[tex]3\,\frac {7}{8}[/tex] = 3 + 7 / 8 = 24 / 8 + 7 / 8 = 31 / 8

[tex]4\,\frac{4}{5}[/tex] = 4 + 4 / 5 = 20 / 5 + 4 / 5 = 24 / 5

[tex]1 \,\frac{1}{2}[/tex] = 1 + 1 / 2 = 2 / 2 + 1 / 2 = 3 / 2

(19 / 2 - 31 / 8) + (24 / 5 - 3 / 2)

(76 / 8 - 31 / 8) + (48 / 10 - 15 / 10)

45 / 8 + 33 / 10

450 / 80 + 264 / 80
