Write the equation of the line in fully simplified slope-intercept form.

The graph that  represents the sum w1 + w2 is: b. A line goes from (0, 0) to point (3, negative 1). On a coordinate plane, the y-axis is labeled imaginary and the x-axis is labeled real.

To find the sum of w1 and w2, we simply add their real and imaginary parts separately:

w1 + w2 = (4 + 2i) + (-1 - 3i) = 3 - i

So the real part of the sum is 3, and the imaginary part is -1. Therefore, the sum w1 + w2 corresponds to the point (3, -1) on the coordinate plane.

The graph that represents this point is option (b), where a line goes from (0, 0) to point (3, -1) on a coordinate plane with the y-axis labeled imaginary and the x-axis labeled real. The other options do not represent the correct point or are not lines passing through the origin.

Answer:

We don't have enough information to answer this question because we don't know the relationship between the functions f(x) and j(x). The fact that the minimum graph of y = j(x) is (-1,-2) only tells us about the behavior of j(x), not f(x).

If we had more information about the relationship between the two functions, we might be able to use the fact that the minimum graph of y = j(x) is (-1,-2) to make some inferences about the minimum point on the graph of y = f(x) + 7. However, without additional information, we cannot provide a specific answer to this question.

Answer: Let's say we want to find out how many red Skittles we need to add to the bag to have the same ratio of red Skittles as in the original bag.

Suppose the original bag contains x red Skittles. Then, the ratio of red Skittles to the total number of Skittles in the bag is x/100.

Let's say we add y red Skittles to the bag, so the total number of red Skittles in the bag becomes x + y. The total number of Skittles in the bag becomes 100 + y, since we only added red Skittles.

For the ratio of red Skittles to be the same as in the original bag, we need:

(x + y) / (100 + y) = x / 100

Cross-multiplying, we get:

100(x + y) = x(100 + y)

Simplifying and rearranging, we get:

y = 100x / (100 - x)

So, we need to add 100x / (100 - x) red Skittles to the bag to have the same ratio of red Skittles as in the original bag. For example, if the original bag has 20 red Skittles, we need to add:

y = 100(20) / (100 - 20) = 25

So, we need to add 25 red Skittles to the bag to have the same ratio of red Skittles as in the original bag.

Step-by-step explanation:

The total amount of interest paid over the life of the loan is $1863.45.

The present value of the loan.

Since there are 12 months in a year, and the loan has n-years, there are 12n monthly payments.

Let's use the formula for the present value of an annuity due:

[tex]PV = PMT \times ((1 - (1 + r) ^(-n)) / r) \times (1 + r)[/tex]

PV is the present value of the loan, PMT is the monthly payment, r is the monthly interest rate, and n is the number of months.

Substituting the given values, we get:

[tex]PV = \$800 \times ((1 - (1 + 0.12/12) ^(-12n)) / (0.12/12)) \times (1 + 0.12/12)[/tex]

[tex]PV = \$800 \times ((1 - (1.01)^(-12n)) / 0.01) \times 1.01[/tex]

[tex]PV = \$800 \times ((1 - 1.01^(-12n)) / 0.01) \times 1.01[/tex]

[tex]PV = \$800 \times ((1 - 0.887^(-n)) / 0.01) \times 1.01[/tex]

The formula for the interest paid in any given month of an annuity due:

[tex]I = PV \times r \times (1 + r) ^(m - 1)[/tex]

I is the interest paid in the 45th month, PV is the present value of the loan, r is the monthly interest rate, and m is the month.

Substituting the given values for the 45th month, we get:

[tex]\$424.45 = PV \times 0.01 \times (1 + 0.01 )^(45 - 1)[/tex]

[tex]\$424.45 = PV \times 0.01 \times (1.01)^4^4[/tex]

[tex]PV = \$424.45 / (0.01 \times (1.01)^4^4)[/tex]

PV =[tex]\$75799.45[/tex]

Now that we know the present value of the loan, we can calculate the total amount of interest paid over the life of the loan.

Let's use the formula for the total interest paid in an annuity due:

[tex]Total interest = (PMT \times n \times (n + 1) / 2) - PV[/tex]

Substituting the given values, we get:

Total interest = [tex](\$800 \times 12n \times (12n + 1) / 2) - \$75799.45[/tex]

Total interest = [tex]\$9600n^2 + \$4800n - \$75799.45[/tex]

We can solve for n by using the fact that the interest paid in the 45th month is $424.45:

[tex]\$424.45 = \$800 \times (n \times 12 - 44) \times 0.01 \times (1 + 0.01)^(45 - 1)[/tex]

[tex]\$424.45 = \$800 \times (n \times 12 - 44) \times 0.01 \times (1.01)^4^4[/tex]

n = 4.5

Substituting n = 4.5 into the formula for total interest, we get:

Total interest =[tex]\$9600 \times (4.5)^2 + \$4800 \times 4.5 - \$75799.45[/tex]

Total interest = $1863.45

The two data sets that have equal standard deviations are:

Data set A: 40, 50, 60, 60, 70, 80

Data set C: 50, 55, 60, 65, 70

To see this, we can calculate the standard deviation for each data set using a formula or a calculator. Alternatively, we can observe that data sets A and C have similar ranges and distributions, which suggests that they may have similar standard deviations. In contrast, data sets B and D have different ranges and distributions, which suggests that their standard deviations may be different.

Answer: We can use a proportion to estimate the total number of fur seal pups in Rookery A. Let x be the total number of fur seal pups in Rookery A. Then we have:

6269/x = 221/1100

Cross-multiplying, we get:

221x = 6269 * 1100

Dividing both sides by 221, we get:

x = 6269 * 1100 / 221

Simplifying, we get:

x = 31,245.25

Rounding to the nearest whole number, we get:

x ≈ 31,245

Therefore, the estimated total number of fur seal pups in Rookery A is 31,245.

The probability of exponential random variables that your job will be ready before 10:01 is approximately 0.0693, or about 6.93%.

We can use the cumulative distribution function (CDF) of the exponential distribution to solve this problem. Let X be the random variable representing the time it takes to print a job. Then, X follows an exponential distribution with parameter λ = 1/12, since the expectation of X is 12 seconds.

The probability that your job will be ready before 10:01 is equal to the probability that the printer finishes the first two jobs in less than 1 minute since your job is third in line.

Let Y be the random variable representing the time it takes to print the first job. Then, Y also follows an exponential distribution with parameter λ = 1/12.

The probability that the first job is finished before 10:01 is given by:

P(Y < 60) = 1 - [tex]$e^{(-\lambda t)}$[/tex] = 1 - [tex]e^{(-(1/12)(60))}[/tex] = 0.3935

Similarly, the probability that the second job is finished before 10:01 is also 0.3935, since it is also an exponential random variable with the same parameter. Therefore, the probability that your job will be ready before 10:01 is:

P(X < 60) = P(Y < 60) × P(Y < 60) × P(X < 60) = 0.3935² × (1 - [tex]$e^{(-\lambda t)}$[/tex]) = 0.0693

Segment CP is tangent to circle C at point B.

How to prove that the line is tangent to a circle?

Draw circle C with center at point A and radius AD = CD = DE.

Draw point P outside the circle C.

Draw segment AP and extend it to intersect the circle at point B.

Draw segment BD.

Draw segment CP.

Note that triangle BCD is isosceles, since CD = BD. Therefore, angle BDC = angle CBD.

Since angle BDC is an inscribed angle that intercepts arc BC, and angle CBD is an angle that intercepts the same arc, then angle BDC = angle CBD = 1/2(arc BC).

Since CD = DE, then angle CED = angle CDE. Therefore, angle DCE = 1/2(arc BC).

Since angles BDC and DCE are equal, then angles BDC and CBD are also equal, and triangle BPC is isosceles. Therefore, segment BP = segment PC.

Since BP = PC, then segment CP is perpendicular to segment BD, by the Converse of the Perpendicular Bisector Theorem.

Therefore, segment CP is tangent to circle C at point B.

Hence, the proof is complete.

The variance of the area of the circle is [tex]\pi^2\theta^{4/45}[/tex].

The mean area of the circle is [tex]\pi\theta^{2/3}.[/tex]

Let X be the radius of the circle, uniformly distributed on [0, θ].

The probability density function of X is given by:

[tex]f(x) = 1/\theta, for 0 \leq x \leq θ[/tex]

= 0, otherwise

Let Y be the area of the circle. Then[tex]Y = \pi X^2.[/tex] We want to find the mean and variance of Y.

Mean of Y:

By the law of the unconscious statistician, the mean of Y is given by:

[tex]E(Y) = E(\pi X^2) = \pi E(X^2)[/tex]

[tex]E(X^2)[/tex] using the formula for the variance of X:

[tex]Var(X) = E(X^2) - [E(X)]^2[/tex]

Since X is uniformly distributed on [0, θ], we have:

[tex]E(X) = (0 + \theta)/2 = \theta/2[/tex]

[tex]Var(X) = [(\theta - 0)^2]/12 = \theta^{2/12}[/tex]

Solving for [tex]E(X^2)[/tex], we get:

[tex]E(X^2) = Var(X) + [E(X)]^2 = \theta^2/12 + (\theta/2)^2 = \theta^{2/3}[/tex]

Substituting this into the expression for E(Y), we get:

[tex]E(Y) = \pi E(X^2) = \pi (\theta ^{2/3}) = \pi \theta^{2/3}[/tex]

Variance of Y:

To find the variance of Y, we can use the formula for the variance of a function of a random variable:

[tex]Var(Y) = E(Y^2) - [E(Y)]^2[/tex]

We can find[tex]E(Y^2)[/tex] using the law of the unconscious statistician:

[tex]E(Y^2) = E[(\pi X^2)^2] = \pi^2E(X^4)[/tex]

To find [tex]E(X^4)[/tex], we can use the formula for the fourth moment of a uniform distribution:

[tex]E(X^4) = (\theta^4 + 2\theta^2)/5[/tex]

Substituting this into the expression for[tex]E(Y^2)[/tex], we get:

[tex]E(Y^2) = \pi^2E(X^4) = \pi^2[(\theta^4 + 2\theta^2)/5] = \pi^2\theta^{4/5} + 2\pi^2\theta^{2/5}[/tex]

Substituting this and the expression for E(Y) into the formula for the variance of Y, we get:

[tex]Var(Y) = E(Y^2) - [E(Y)]^2[/tex]

[tex]= \pi^2\theta^{4/5} + 2\pi^2\theta^{2/5} - (\pi\theta^2/3)^2[/tex]

It will take approximately 29 days for the ant population to drop below 250.

The logarithmic function to the base e is called the natural logarithmic function and it is denoted by loge.

f(x) = loge x

To find out how many days it will take for the ant population to drop below 250, we need to solve for the value of t in the equation:

A(t) = [tex]45000*(0.271)^t[/tex]< 250

We can start by simplifying the equation:

[tex]45000*(0.271)^t[/tex]< 250

[tex](0.271)^t[/tex] < 250/45000

[tex](0.271)^t[/tex]< 0.00555556

Next, we can take the natural logarithm of both sides to isolate t:

ln[[tex](0.271)^t][/tex] < ln(0.00555556)

t*ln(0.271) < ln(0.00555556)

t > ln(0.00555556) / ln(0.271)

t > 28.32

To find the radius of convergence, R, of the collection, we can use the ratio test:

[tex]lim_n→∞ |(a_(n+1)/[/tex][tex]a_n)|[/tex]

[tex]lim_n→∞ |(a_{(n+1})/[/tex]

[tex]= lim_n→∞ |(x+8) / 4| * |ln(n+1) / ln(n)|[/tex]

For the series to converge, this limit need to be less than 1. therefore, we've:

[tex]|(x+8) / 4| * lim_n→∞ |ln(n+1) / ln(n)| < 1[/tex]

For the reason that[tex]lim_n→∞ |ln(n+1) / ln(n)| = 1[/tex], we will simplify this to:

|(x+8) / 4| < 1

Taking the absolute cost under consideration, we have cases:

Case 1: (x+8)/4 < 1

In this case, we have x < -4.

Case 2: (x+8)/4 > -1

In this case, we have x > -12.

Consequently, the radius of convergence is the distance from the center of the collection (x = -8) to the closest endpoint of the c language (-12 on the left and -4 at the right):

What is volume?

A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder, or a sphere. Different shapes have different volumes

The volume of a solid with a hollow cylinder can be calculated by subtracting the volume of the inner cylinder from the volume of the outer cylinder.

Assuming the dimensions in the figure are in inches, the outer cylinder has a height of 17 inches and a radius of 9 inches, so its volume is:

[tex]V_{outer} = \pi * r^2 * h[/tex]

= π × 9² × 17 ≈ 4,842.51 in³

The inner cylinder has a height of 12 inches and a radius of 3 inches, so its volume is:

[tex]V_{inner} = \pi * r^2 * h[/tex] = π × 3² × 12 ≈ 339.29 in³

To find the volume of the solid, we need to subtract the volume of the inner cylinder from the volume of the outer cylinder:

So, it will take approximately 0.1818 hours (around 11 minutes) for Bill's wife to catch up to him.

To determine how long it will take Bill's wife to catch up to him, we can use the concept of relative speed.

First, let's calculate the distance Bill covers in 30 minutes (0.5 hours) before his wife starts driving:
Distance = Speed × Time
Distance = 8 mph × 0.5 hours = 4 miles

Now, let's calculate the relative speed between Bill and his wife:
Relative Speed = Wife's Speed - Bill's Speed
Relative Speed = 30 mph - 8 mph = 22 mph

Now, we can calculate the time it will take for Bill's wife to catch up to him:

The total length of fences needed to surround the parks is 1500 feet. The length is calculated by adding up the lengths of all sides of both parks.

To find the total length of fences needed to surround the parks, we need to add up the lengths of all the sides of both parks.

For park RST, the total length of the fences needed is

RS + ST + RT = 230 + 350 + 230 = 810 ft

For park XYZ, since YX is congruent to XYZ, we can label YX as YZ for simplicity. The total length of the fences needed for park XYZ is

XY + YZ + XZ = YZ + YZ + 230 = 2YZ + 230

To find YZ, we can use the fact that park RST is congruent to park XYZ, so the corresponding sides are equal in length. This means YZ = RT = 230 ft.

Substituting this value, we get

2YZ + 230 = 2(230) + 230 = 690 ft

Therefore, the solution to the system of equation is (x, y) = (-5, 9).

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, the left-hand side and the right-hand side, separated by an equals sign (=). An equation can contain variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division.

Here,

To solve the system using linear combination, we want to eliminate one of the variables by adding the two equations together.

{3x + 4y = 21

{5x + 4y = 11

Notice that if we subtract the first equation from the second, we get:

(5x + 4y) - (3x + 4y) = 11 - 21

2x = -10

x = -5

Now we can substitute x = -5 into either of the original equations and solve for y:

3x + 4y = 21

3(-5) + 4y = 21

-15 + 4y = 21

4y = 36

y = 9

Answer:

13.416407865

Step-by-step explanation:

You wouldn't use soh cah toa

There is no angle given. Instead you should do 6²+12²=180

And then you would square root 180=13.416407865

Therefore the answer is 13.416407865

The surface area of this solid would be; 127.

To Find the surface area of the composite solid, we have;

Sides (a) area

4 * 3 = 12

12 * 2 = 24

Now Sides (b) area

7 * 3 = 21

21 * 3 = 63

Then Face (c) area

3 * 4 / 2 = 6

6 * 2 = 12

Base area

4 * 7 = 28

Total surface area

To calculate the total surface area we have to add the value of each face :

28 + 12 + 63 + 24 = 127

Thus, the surface area of this solid is 127.
