one line passes through (-3, -1) and (2,4) another passes through points (2, -6) and (7, -1). are the lines parallel, perpendicular, or neither?

Answers

Answer 1

Answer:

Since they both have the same slope, they are Parallel.

Step-by-step explanation:

We will have to calculate slope for this equation using this formula:

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

For line 1 our points are:

(-3,-1) and (2,4)

Substitute:

[tex]\frac{4+1}{2+3}[/tex]

[tex]\frac{5}{5}[/tex]

The slope for the first line is 1.

For line 2 our points are:

(2,-6) and (7,-1)

Substitute:

[tex]\frac{-1+6}{7-2}[/tex]

[tex]\frac{5}{5}[/tex]

The slope for this equation is 1.

For these lines to be parallel, they would need their slopes to be the same.

For these lines to be perpendicular, they would need to be opposite reciprocals.

Since they both have the same slope, they are Parallel.

Answer 2

Answer:

Parallel

Step-by-step explanation:

(-3, -1) and (2,4) -

First find the slope of the line using the slope formula [tex]\frac{y2-y1}{x2-x1}[/tex] :  [tex]\frac{4-(-1)}{2-(-3)}[/tex]

Add the numbers : [tex]\frac{5}{5}[/tex]

Simplify: 1

Using one of the given ordered pairs find the y-intercept: 4 = 1(2) + b

Caluclate the product : 4 = 2 + b

Move the variable to the left-hand side and change its sign: -b = 2 - 4

Calulate the diffrence and change the signs: b = 2

Using the slope and y- intersept creat your equation : y = 1x + 2

(2, -6) and (7, -1)-

First find the slope of the line using the slope formula [tex]\frac{y2-y1}{x2-x1}[/tex] : [tex]\frac{-1-(-6)}{7-2}[/tex]

Add the numbers : [tex]\frac{5}{5}[/tex]

Simplify: 1

Using one of the given ordered pairs find the y-intercept: -6 = 1(2) + b

Caluclate the product : -6 = 2 + b

Move the variable to the left-hand side and change its sign: -b -6 = 2

Calulate the sum and change the signs: b = -8

Using the slope and y- intersept creat your equation : y = 1x + -8

Parallel lines have the same slope and different y-intercepts

The probability that a 22-year-old female in the U.S. will die within one year is approximately 0.00044. If an insurance company sells a one-year, $30,000 life insurance policy to such a person for $435, what is the company's expectation? (Round your answer to the nearest dollar.)

Answers

Answer:

The value is  [tex]E(X) = \$ 421.6[/tex]

Step-by-step explanation:

From the question we are told that

The probability that a 22 year  old  female in US will die within one year is    p= 0.00044

The outcome if she dies within one year is that the company losses $30,000

Generally the probability that  a 22 year  old  female in US will live more than one year is

           [tex]q = 1 -p[/tex]

=>        [tex]q = 1 -0.00044[/tex]

=>        [tex]q = 0.99956[/tex]

The outcome if she lives more than one year is that the company gains $435

Generally the  the company's expectation is mathematically represented as

           [tex]E(X) = -30000 * p + 435 * q[/tex]

The negative sign shows that the company is loosing the fund

So  

       [tex]E(X) = -30000 * 0.00044 + 435 * 0.99956[/tex]

=>    [tex]E(X) = \$ 421.6[/tex]

[tex]a_{n}[/tex] = 5n - 22

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₂ = - 12 , then

a₁ + d = - 12 , that is

a₁ + 5 = - 12 ( subtract 5 from both sides )

a₁ = - 17

Thus

[tex]a_{n}[/tex] = - 17 + 5(n - 1)

    = - 17 + 5n - 5

     = 5n - 22

the length of a rectangular sign is 4 times it's width. if the sign's perimeter is 30 inches, what is the area?

Answers

Answer:

36

Step-by-step explanation:

Width = x

Length = 4x

Perimeter = Width + Width + Length + Length (Because there are four sides; two sides are the widgth and two sides are the length)

30 (because 30 is given as the perimeter) = x + x + 4x + 4x

30 = 10x

x = 3

Width = 3

Length = 4(3) = 12

Area = Width * Length

Area = 3 * 12 = 36

The area of the rectangular sign is equal to 36 square inches, if its perimeter is 30 inches.

Let the length of the rectangular sign be L.Let the width of the rectangular sign be W.

Given the following data:

Perimeter of rectangular sign = 30 inches.

Translating the word problem into an algebraic equation, we have;

[tex]L = 4W[/tex]

Mathematically, the perimeter of a rectangle is given by the formula;

[tex]P = 2(L+W)\\\\30 = 2(4W + W)\\\\30 = 2(5W)\\\\30 = 10W\\\\W = \frac{30}{10}[/tex]

Width, W = 3 inches

For its length:

[tex]L = 4W\\\\L = 4(3)[/tex]

Length, L = 12 inches.

Now, we can determine the area of the rectangular sign by using the formula:

[tex]Area = LW\\\\Area = 12(3)[/tex]

Area = 36 square inches.

Therefore, the area of the rectangular sign is equal to 36 square inches.

The boundary of a lamina consists of the semicircles y = 1 − x2 and y = 64 − x2 together with the portions of the x-axis that join them. Find the center of mass of the lamina if the density at any point is proportional to its distance from the origin.

Answers

Answer:

The center mass of the lamina =   [tex]{\begin {pmatrix} 0, \dfrac{1755}{146 \pi } \end {pmatrix}[/tex]

Step-by-step explanation:

Let take a look at the boundary of the lamina that comprises of the semicircles [tex]y = \sqrt{1-x^2}[/tex] and [tex]y = \sqrt{64-x^2}[/tex]

We are also informed that the density at any point is proportional to its distance from the origin.

Thus, the main task required is to find the center mass of the lamina.

In as much as the density is proportional to the distance from the origin;

Then;

[tex]\rho (x,y) = k \sqrt{x^2 + y^2} = kr[/tex]

Thus; the mass of the lamina is determined as:

[tex]m = \iint \limits _ D \rho (x,y) \ dA= \int ^{\pi}_{0}\int ^{8}_{1} kr.r dr d \theta[/tex]

[tex]m = \int ^{\pi}_{0}\int ^{8}_{1} kr^2 dr d \theta[/tex]

[tex]m = k \int ^{\pi}_{0} \begin {bmatrix} \int \limits ^8_1 r^2 dr \end {bmatrix} d \theta[/tex]

[tex]m = k \int ^{\pi}_{0} \begin {bmatrix} \int \limits\dfrac{r^3}{3} \end {bmatrix} ^8_1d \theta[/tex]

[tex]m = k \int ^{\pi}_{0} \begin {bmatrix} \dfrac{512}{3}- \dfrac{1}{3} \end {bmatrix} d \theta[/tex]

[tex]m = \dfrac{511 \ k}{3} \int \limits ^{\pi}_{0} \ d \theta[/tex]

[tex]m = \dfrac{511 \ k}{3} \bigg (\theta \bigg ) ^{\pi}_{0}[/tex]

[tex]m = \dfrac{511 \ k \pi}{3}[/tex]

Now, about the y-axis, the moment of the entire lamina can be computed as:

[tex]M_y = \iint \limits _D x\rho (x,y) \ dA = \int \limits^{\pi}_{0} \int \limits ^{8}_{1} r cos \theta kr .r \ dr \ d \theta[/tex]

[tex]M_y = k \int \limits ^{\pi}_{0} \int ^{8}_{1} \ cos \theta . r^3 \ dr \ d \theta[/tex]

[tex]M_y = k \begin {bmatrix} \int \limits ^{\pi}_{0} cos \theta d \theta \end {bmatrix} \begin {bmatrix} \int \limits ^8_1 r^3 dr \end {bmatrix}[/tex]

[tex]M_y = k (sin \ \theta )^{\pi}_{0} \begin {bmatrix} \dfrac{r^4}{4} \end {bmatrix}^8_1[/tex]

[tex]M_y = k(sin \pi - sin 0 ) \bigg ( \dfrac{8^4}{4}- \dfrac{1^4}{4} \bigg)[/tex]

[tex]M_y = 0[/tex]

Similarly; about the x-axis, the moment of the entire lamina can be computed as:

[tex]M_x = \iint \limits _D y \rho (x,y) \ dA = \int \limits^{\pi}_{0} \int \limits ^{8}_{1} r sin \theta kr .r \ dr \ d \theta[/tex]

[tex]M_x = k \int \limits ^{\pi}_{0} \int ^{8}_{1} \ sin \theta . r^3 \ dr \ d \theta[/tex]

[tex]M_x = k \begin {bmatrix} \int \limits ^{\pi}_{0} sin \theta d \theta \end {bmatrix} \begin {bmatrix} \int \limits ^8_1 r^3 dr \end {bmatrix}[/tex]

[tex]M_x= k (- cos \ \theta )^{\pi}_{0} \begin {bmatrix} \dfrac{r^4}{4} \end {bmatrix}^8_1[/tex]

[tex]M_x = k(-cos \pi +cos 0 ) \bigg ( \dfrac{8^4}{4}- \dfrac{1^4}{4} \bigg)[/tex]

[tex]M_x = \dfrac{4095}{2}k[/tex]

Hence,  The center mass of the lamina is:

[tex]( \overline x, \overline y) = \bigg ( \dfrac{M_y}{m}, \dfrac{M_x}{m} \bigg )[/tex]

[tex]( \overline x, \overline y) = \begin {pmatrix} \dfrac{0}{\dfrac{511 \ k \pi}{3}}, \dfrac{\dfrac{4095 \ k}{2}}{\dfrac{511 \ k \pi}{3}} \end {pmatrix}[/tex]

[tex]( \overline x, \overline y) = \begin {pmatrix} 0, \dfrac{1755}{146 \pi } \end {pmatrix}[/tex]

Ramen noodles. There are 20 ramen noodle packages in a bag. There are 10 beef flavored, and the other 10 are chicken flavored. What is the probability of getting at least one chicken and at least one beef flavor when you grab 3 packages randomly?

Answers

Answer:

0.789

Step-by-step explanation:

Number of beef flavored Ramen noodles = 10

Number of chicken flavored Ramen noodles = 10

Total number of noodles = 20

Number of ways to select 3 packages:

[tex]_{20}C_3= \dfrac{20\times 19\times 18}{3\times 2\times 1}=1140[/tex]

Number of ways to select two beef flavored Ramen noodle = [tex]_{10}C_2[/tex] = 45

Number of ways to select one chicken flavored Ramen noodle = 10

Number of ways to select two chicken flavored Ramen noodle = [tex]_{10}C_2[/tex] = 45

Number of ways to select one chicken flavored Ramen noodle = 10

Total number of ways so that one chicken and one beef Ramen selected = 450 + 450 = 900

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Required probability is:

[tex]\dfrac{900}{1140} = 0.789[/tex]

Dennis wants to save $189 for a trip to an amusement park. He sets aside $14 of his allowance at the end of each week. How many weeks will it take him to save enough money for the whole trip?

Answers

Answer:

x = 13.5 weeks

Step-by-step explanation:

Since he wants to save $189 in total, that will be on one side of the equation by itself. You have to set this up in a y = mx + b equation. The y will be the 189. Since the word "each" goes with the number 14, that will be your m value. There is no value for b.

189 = 14x is your equation. The only step after setting up the equation is to divide 189 by 14. This gives you 13.5. Dennis will have to save up for 13.5 weeks.
