Answers

Answer 1

a)

d)

1) Since the zeros of that polynomial were given, then we can write it into the factored form. Note that there are 4 zeros, so we can write:

[tex]\begin{gathered} (x-x_1)(x-x_2)(x-x_3)(x-x_4)=0 \\ (x-(-2i))(x-2i)(x-3)(x-(-4))=0 \\ (x+2i))(x-2i)(x-3)(x+4))=0 \end{gathered}[/tex]

2) To find out the corresponding polynomial then we can expand it by rewriting "i" as -1

[tex]\begin{gathered} (x+2i))(x-2i)(x-3)(x+4) \\ (x+2i)(x-2i)=x^2+4 \\ (x-3)(x+4)=x^2+4x-3x-12 \\ (x^2+4)(x^2+x-12) \\ x^4+x^3-8x^2+4x-48 \end{gathered}[/tex]

the question is on the sheet .The shaded region is the area within the figure but not the corner squares

Answers

Based on the information given in the exercise, you know that the shaded region has this area:

[tex]6x^2-2xy+3y^2[/tex]

And the area of each square region in the corners is:

[tex]4x^2[/tex]

Since there are four square regions, you can multiply that the area of any of them by 4, in order to find the total area of them:

[tex]4(4x^2)=16x^2[/tex]

Then, in order to find the total area of the figure, you must add the area of the shaded region and the total area of the square regions:

[tex](6x^2-2xy+3y^2)+(16x^2)=22x^2^{}-2xy+3y^2[/tex]

Therefore, the total of the figure is:

What is the area of this rectangle?
3
7b ft
7
3
b+21 ft

Answers

Step-by-step explanation:

the area of a rectangle is

length × width.

in our case that is

(7/3 × b + 21) × (3/7 × b) =

= 7/3 × 3/7 × b × b + 21 × 3/7 × b =

= 1 × b² + 3×3 × b = b² + 9b = b(b + 9) ft²

so, the area is

b² + 9b = b(b + 9) ft²

remember, an area is always a square "something".

a volume a cubic "something".

so, when the lengths are given in feet, the areas are square feet or ft².

The perimeter of a rectangle is 48 centimeters. The relationship between the length, the width, and the perimeter of the rectangle can be described with the equation 2⋅length+2⋅width=48. Find the length, in centimeters, if the width is w centimeters

Answers

Using the relationship between the dimension of a rectangle and its perimeter, given its perimeter and width, the length is: 20.4 cm.

Recall:

Perimeter of a rectangle (P) = 2(L + W) (relationship between the width, length and perimeter)

Given:

Width (W) = 3.6 cm

Perimeter (P) = 48 cm

Length (L) = ?

Using the relationship between the dimension of a rectangle and its perimeter, the following equation would be derived:

48 = 2(L + 3.6)

Solve for the value of L

48 = 2L + 7.2

Subtract 7.2 from each side

48 - 7.2 = 2L

40.8 = 2L

Divide both sides by 2

20.4 = L

L = 20.4 cm

Therefore, using the relationship between the dimension of a rectangle and its perimeter, given its perimeter and width, the length is: 20.4 cm.

Pete Corporation produces bags of peanuts. Its fixed cost is $18,200. Each bag sells for $3.43 with a unit cost of $1.83. What is Pete’s breakeven point?

Answers

Let's call x to the bags of peanuts. One bag has a variable cost of $1.83, then the variable cost of x bags is 1.83x dollars.

The total cost of production for the corporation is obtained by adding fixed and variable costs. In this case, the total cost is 18,200 + 1.83x dollars.

The revenue for the corporation of 1 bag is $3.43, then of x bags is 3.43x dollars.

When the revenue and the total cost are equal, the breakeven point is reached, in this case:

18,200 + 1.83x = 3.43x

18,200 = 3.43x - 1.83x

18,200 = 1.6x

18,200/1.6 = x

11375 = x

The cost of production of 11375 bags is:

Total Cost = 18,200 + 1.83*11375

Total Cost = 18,200 + 20816.25

Total Cost = 39016.25

Pete’s breakeven point is (11375, 39016.25), or, 11375 bags and $39,016.25

A 90% confidence interval for the proportion of cell phone owners aged 18 - 24 who have an Android phone is

..............< p <...............

We have to construct the 90% confidence interval.

From the given question we know that among 240 cell phone owners aged 18 - 24 surveyed, 108 said their phone was an android phone.

So the total number of cell phone owners aged 18 - 24 is 240.

So n=240

From them 108 have an android phone.

So x=108

Estimation of sample proportion([tex]\hat p[/tex]) = x/n

Now putting the value

Estimation of sample proportion([tex]\hat p[/tex]) = 108/240

Estimation of sample proportion([tex]\hat p[/tex]) = 0.45

C.I. = [tex](\hat p \pm z_{\alpha /2}\sqrt\frac{\hat p(1-\hat p)}{n}})[/tex]

As we know that

Now finding the value of [tex]z_{\alpha /2}[/tex]

We have to find the 90% confidence interval. We can write 90% as 90/100 = 0.90

So [tex]\alpha[/tex] = 1-0.90

So [tex]z_{\alpha /2}=z_{0.10 /2}[/tex]

[tex]z_{\alpha /2}=z_{0.05}[/tex]

From the standard z table

[tex]z_{0.05}[/tex] = 1.645

Now putting the value in the

C.I. = [tex](0.45 \pm 1.645{\sqrt\frac{0.45(1-0.45)}{240}})[/tex]

Simplifying

C.I. = [tex](0.45 \pm 1.645{\sqrt\frac{0.45\times0.55}{240}})[/tex]

C.I. = [tex](0.45 \pm 1.645{\sqrt\frac{0.2475}{240}})[/tex]

C.I. = [tex](0.45 \pm 1.645\times0.0321)[/tex]

Answers

The cost price of dealer is $512.

We have to find the dealer's cost of refrigerator.

We know that mark up is on dealer's cost.

We have been given the markup as 5%

Let the dealer's cost of refrigerator be x,

Now, we know that there is a markup on it

So, we will calculate the marked up price

Marked up price = (Cost price * Markup percent)/100 + cost price

Marked up price = x*5/100 + x

Marked up price = 5x/100 + x

Marked up price = x/20 + x = (x+20x)20

Marked up price = 21x/20

We know that marked up price is the selling price and we have been given the selling price of the refrigerator

Answers

We have the sequence: 40, 20, 10, 5,...

Each term is half the previous term, so it is a geometrical sequence with common ratio r = 0.5.

We can not complete the sequence, as it becomes infinitely smaller and does not have a last term.

But we can write the three next terms to complete the blank spaces: 2.5, 1.25, 0.625.

We can start by writing the recursive formula. We know that each term is half the value of the previous term, so we wil have:

[tex]a_n=0.5\cdot a_{n-1}[/tex]

From this recursive formula, we can deduce the explicit formula (in terms of n) as:

[tex]\begin{gathered} a_1=40 \\ a_2=0.5\cdot40=20 \\ a_3=0.5\cdot20=0.5\cdot(0.5\cdot40)=0.5^2\cdot40=10 \\ a_4=0.5\cdot10=0.5\cdot(0.5^2\cdot40)=0.5^3\cdot40 \\ \Rightarrow a_n=40\cdot0.5^{n-1} \end{gathered}[/tex]

A = The event of the driver wearing a seat belt in a car accident.

B = The event of the driver dying in a car accident

The conditional probability is calculated as follows:

[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}[/tex]

The conditional probability stated in the formula is that for the driver wearing a seat belt knowing he did not survive the car accident.

The numerator of the formula is the probability of both events occurring, i.e., the driver wore a seat belt and died. The denominator is the simple probability that the driver died in a car accident.

From the table, we can intersect the first column and the second row to find the number of outcomes where both events occurred. The probability of A ∩ B is:

[tex]P(A\cap B)=\frac{511}{583,470}[/tex]

The probability of B is:

[tex]P(B)=\frac{2217}{583,470}[/tex]

The required probability is:

[tex]P(A|B)=\frac{\frac{511}{583,470}}{\frac{2217}{583,470}}[/tex]

Simplifying the common denominators:

[tex]P(A|B)=\frac{511}{2217}=0.230[/tex]

Slope intercept

Answers

The slope of the given coordinates is m = 1/2.

What is the slope?A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x). The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b. M represents the line's slope. B is the b in the point where the y-intercept is located (0, b). For instance, the slope and y-intercept of the equation y = 3x - 7 are 3 and 0, respectively.

So, the slope of (2, -3) (4, -2):

The slope formula: m = y₂ - y₁/x₂ - x₁

Now, solve for slope by putting the values as follows:

m = y₂ - y₁/x₂ - x₁m = -2 - (-3)/4 - 2m = -2 + 3/2m = 1/2

Therefore, the slope of the given coordinates is m = 1/2.

Name a postulate or theorem that can be used with the given information to prove that the lines are parallel<3 ~ <7

Answers

Postulates and Theorems of Parallel Lines

First, we need to know what type of angles are <3 and <7. Following the definition:

If two lines are crossed by another line, the angles in matching corners are called Corresponding Angles.

Angles 3 and 7 are corresponding angles and they are told to be congruent.

Now we apply the postulate that reads:

The Converse of the Corresponding Angles Postulate. If two lines are cut by a transversal so that corresponding angles are congruent, then the lines are parallel.

The postulate that can be used to prove that the lines are parallel is The Converse of the Corresponding Angles Postulate
