What are triangles?

In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Unless when otherwise specified, this article discusses triangles in Euclidean geometry, namely the Euclidean plane.

Extend the segment AB and draw a perpendicular line from B to C.

From the figure we see that:

tan (42) = y / 325 + x

y = tan (42) (325 + x)

Also, tan (70) = y / x

y = tan(70) x

Equating the values of y together we have:

tan (42) (325 + x) = tan(70) x

x = 158.430

Now,

cos (70) = 158.430/h

h = 463.2 ft

Hence, the value of the distance BC across the lake to the nearest foot is 463 ft.

fill in the blank. counting 67 colonies on a plate with 1ml of the 1:1,000,000 dilution indicates that___bacteria were present in 1ml of the original sample.

Answers

By applying the unitary method, counting 67 colonies on a plate with 1ml of the 1:1,000,000 dilution indicates that 67,000,000 bacteria were present in 1ml of the original sample.

The unitary method is a mathematical technique that involves finding a unit value and using it to solve problems. In this case, we need to determine the number of bacteria present in 1ml of the original sample.

The dilution factor represents the ratio of the volume of the original sample to the volume of the diluted sample. In this case, the dilution factor is 1:1,000,000, which means that 1ml of the original sample was diluted with 1,000,000ml of a diluent solution to obtain 1ml of the diluted sample. Therefore, the number of bacteria in the original sample is 1,000,000 times the number of bacteria in the diluted sample.

Now, let's use the colony count to determine the number of bacteria in the diluted sample. We are told that 67 colonies were counted on the plate with 1ml of the 1:1,000,000 dilution. This means that each colony represents the growth of a single bacterium in the diluted sample. Therefore, the number of bacteria in the diluted sample is 67.

Using the unitary method, we can now determine the number of bacteria in 1ml of the original sample. We know that the number of bacteria in the original sample is 1,000,000 times the number of bacteria in the diluted sample. Therefore:

Number of bacteria in original sample = Dilution factor x Number of bacteria in diluted sample

Number of bacteria in original sample = 1,000,000 x 67

Number of bacteria in original sample = 67,000,000

So, the answer is that 67,000,000 bacteria were present in 1ml of the original sample.

For the pair of parametric equations below, eliminate the parameter to find its Cartesian equation. Also specify the domain and range of your equation using interval notation.
x(t)=2cos(t)
y(t)=2sin(t)

Answers

The Cartesian Equation of the given parametric equation is written below

: x^2 + y^2=4

To eliminate the parameter t and find the Cartesian equation, we can use the trigonometric identity: cos^2(t) + sin^2(t) = 1. We can rearrange the given equations to get:

x(t) = 2cos(t)

y(t) = 2sin(t)

Dividing both sides of each equation by 2, we get:

cos(t) = x/2

sin(t) = y/2

Squaring both equations and adding them, we get:

cos^2(t) + sin^2(t) = (x/2)^2 + (y/2)^2

Using the identity, we can simplify the right-hand side to get:

1 = (x/2)^2 + (y/2)^2

Multiplying both sides by 4, we get the Cartesian equation:

x^2 + y^2 = 4

This is the equation of a circle with radius 2 centered at the origin. The domain of this equation is all real numbers, and the range is from -2 to 2 (inclusive) in both the x and y directions, represented as [-2,2].

In summary, the Cartesian equation of the given parametric equations is x^2 + y^2 = 4, with domain of all real numbers and range of [-2,2].

A species with an initial population of 350
is growing in an environment where the
carrying capacity is 7000. After 5 years
the population is up to 900. Find the
logistic function that models this
population as a function of time.

Answers

Answer:

the logistic function that models the population of this species as a function of time is P(t) = 7000 / (1 + 0.05 * e^(-0.1682 * t)).

Step-by-step explanation:

We can use the logistic growth equation to model the population of this species as a function of time:

P(t) = K / (1 + A * e^(-r * t))

Where:

P(t) is the population at time t

K is the carrying capacity of the environment

A is the initial population as a proportion of the carrying capacity (A = P(0)/K)

r is the growth rate of the population

We are given that the initial population A is 350/7000 = 0.05 (since the carrying capacity is 7000). We are also given that after 5 years the population has grown to 900. So we can use this information to find the growth rate r:

P(5) = 900 = K / (1 + A * e^(-r * 5))

We also know that the carrying capacity K is 7000. Substituting these values, we get:

900 = 7000 / (1 + 0.05 * e^(-r * 5))

Multiplying both sides by the denominator and simplifying, we get:

1 + 0.05 * e^(-r * 5) = 7.777...

Subtracting 1 from both sides, we get:

0.05 * e^(-r * 5) = 6.777...

Dividing both sides by 0.05, we get:

e^(-r * 5) = 135.555...

Taking the natural logarithm of both sides, we get:

-ln(135.555...) = -r * 5

Solving for r, we get:

r = 0.1682...

Now that we have the growth rate r, we can use the logistic growth equation to find the function that models the population as a function of time:

P(t) = 7000 / (1 + 0.05 * e^(-0.1682 * t))

Therefore, the logistic function that models the population of this species as a function of time is P(t) = 7000 / (1 + 0.05 * e^(-0.1682 * t)).

determine whether the lines and are parallel, skew, or intersecting. if they intersect, find the point of intersection. stewart, james. essential calculus (p. 579). cengage textbook. kindle edition.

Answers

The lines L1 and L2 are not parallel and intersect at a single point. We have also found the point of intersection.

If the direction vectors are parallel, then the lines are parallel. If the direction vectors are not parallel but do not intersect, then the lines are skew. If the direction vectors are not parallel and do intersect, then the lines intersect at a single point.

To determine whether the given lines are parallel, skew, or intersecting, we need to compare their direction vectors. The direction vectors of the lines are the coefficients of the parameters t and s in the respective equations. Thus, the direction vector of L1 is <2,-1,3> and the direction vector of L2 is <4,-2,5>.

To check whether the direction vectors are parallel, we can compute their cross product. If the cross product is the zero vector, then the direction vectors are parallel.

<2,-1,3> × <4,-2,5> = (7,2,-10)

Since the cross product is not zero, the direction vectors are not parallel. Thus, the lines are either skew or intersecting.

To determine whether the lines are intersecting, we can set the parametric equations of the lines equal to each other and solve for t and s. This will give us the point of intersection.

3 + 2t = 1 + 4s

4 - t = 3 - 2s

1 + 3t = 4 + 5s

Rearranging the equations, we get:

2t - 4s = -2

t + 2s = 1

3t - 5s = 3

Using Gaussian elimination or other methods, we can solve for t and s:

t = 11/13

s = 2/13

Substituting these values back into either equation gives us the point of intersection:

x = 3 + 2(11/13) = 37/13

y = 4 - (11/13) = 41/13

z = 1 + 3(11/13) = 40/13

Thus, the lines intersect at the point (37/13, 41/13, 40/13).

Ordinal data is a type of categorical data with an order. The variables in ordinal data are listed in an ordered manner. The ordinal variables are generally numbered, so as to indicate the order of the list.

Age can be both nominal and ordinal data depending on the question types. I.e “ How old are you ” is used to collect nominal data while “ Are you the firstborn or What position are you in your family ” is used to collect ordinal data.

An interval variable is analogous to an ordinal variable, except that the intervals between the values of the numerical variable are inversely spaced.

A categorical variable( occasionally called a nominal variable) is one that has two or further orders, but there's no natural ordering to the orders.

situation. How long could each be fired alone?

Answers

Using equations, the time for the main engine 14.4 seconds and 21.6 seconds for the auxiliary engine

What is the equation to represent the situation

Let's call the time each engine takes to consume its allotted fuel supply as "t₁" for the main engine and "t₂" for the auxiliary engine.

From the first piece of information, we know:

t₁ = (2/3)t₂

From the second piece of information, we know that the combined fuel consumption time for both engines is 36 seconds:

t₁ + t₂ = 36

Now we can substitute the first equation into the second:

t₁ + (2/3)t₂ = 36

Combining like terms:

t₂ = 21.6

Finally, substituting t₂ back into the first equation:

t₁ = (2/3)(21.6) = 14.4

So the main engine alone could be fired for 14.4 seconds and the auxiliary engine alone could be fired for 21.6 seconds.

A memoryless, time invariant, linear, casual, and stable system is an idealized system in which the output is directly proportional to the input and the output at any given time is independent of the outputs at any other time.

The system is stable in the sense that the output does not grow indefinitely as the input increases, and it is casual in the sense that the output at any given time is only affected by the inputs at previous times.

In a running competition, a bronze, silver and gold medal must be given to the top three girls and top three boys. If 7 boys and 14 girls are competing, how many different ways could the six medals possibly be given out?​

Answers

Answer:

there are 458640 different ways to award the six medals.

Step-by-step explanation:

There are two distinct groups in the competition, boys and girls. The order in which the medals are awarded to the groups does not matter, so we can count the number of ways to award medals to the boys and the girls separately, and then multiply the results.

For the boys, there are 7 possible candidates for the gold medal. Once the gold medalist is chosen, there are 6 remaining candidates for the silver medal, and 5 candidates for the bronze medal. So, there are 7 x 6 x 5 = 210 ways to award medals to the boys.

Similarly, for the girls, there are 14 possible candidates for the gold medal. Once the gold medalist is chosen, there are 13 remaining candidates for the silver medal, and 12 candidates for the bronze medal. So, there are 14 x 13 x 12 = 2184 ways to award medals to the girls.

To get the total number of ways to award the six medals, we multiply the number of ways to award medals to the boys by the number of ways to award medals to the girls:

Total number of ways = 210 x 2184 = 458640

Therefore, there are 458640 different ways to award the six medals.

Find three consecutive integers such that the sum of the first and the third is 8 more than the second number.

Answers

Answer: Let's call the first integer "x". Then, the second integer would be x + 1, and the third integer would be x + 2.

According to the problem, the sum of the first and the third integer is 8 more than the second integer:

x + (x + 2) = (x + 1) + 8

Simplifying the left side of the equation:

2x + 2 = x + 9

Subtracting x from both sides:

x + 2 = 9

Subtracting 2 from both sides:

x = 7

So the first integer is 7, the second integer is 8, and the third integer is 9. These are three consecutive integers that satisfy the condition in the problem.

Assume Marleen adds security Y to her portfolio that is less than perfectly positively correlated with the portfolio. Security Y has the same standard deviation as the portfolio. What will happen to the standard deviation of the portfolio after she adds security Y?
Select one:
It will remain the same
It will decrease
It will increase
It may increase or decrease, depending on the weightings of the portfolio holdings

Answers

The standard deviation of the portfolio may increase or decrease, depending on the weightings of the portfolio holdings. after she adds security Y

The portfolio standard deviation as a result of revealing how reliable an investment's earnings are, mean serves as a risk indicator. Because it reveals that the earnings are extremely unstable and fluctuating, a high standard deviation in a portfolio denotes significant risk.

The statistical measure of market volatility used to determine how widely prices deviate from the average price is called standard deviation. The standard deviation will show a low number, which denotes little volatility if prices move within a small range of prices.

The term "standard deviation" (or " σ") refers to a measurement of the data's dispersion from the mean.

Solve triangle ABC. (If an answer does not exist, enter DNE. Round your answers to one decimal place. Below, enter your answers so that angle A1 is smaller than angle A2).
Givens: b = 126, c = 162, angle B = 43 degrees

Answers

The triangle ABC has sides of length a = 106.5, b = 126, and c = 162, and angles A = 83.3, B = 43, and C = 53.7. Additionally, we have A₁ = 32.7, A₂ = 32.7, and C₁ = 8.2.

To solve the triangle ABC, we can use the Law of Cosines and the Law of Sines.

First, we can use the Law of Cosines to find the length of side a, which is opposite angle A:

a² = b² + c² - 2bc cos(B)

a² = (126)² + (162)² - 2(126)(162) cos(43)

a = 106.5

Next, we can use the Law of Sines to find angle A:

sin(A) / a = sin(B) / b

sin(A) = (a sin(B)) / b

A = 83.3

To find angle C, we can use the fact that the angles of a triangle add up to 180:

C = 180 - A - B

C = 53.7

Next, we can use the given relationship between angles A₁ and A₂ to find their values:

A₂ = A₁ = 2C₁

A₁ + A₂ + C₁ = 180

A₁ + 2A₁ + A₁/2 = 180

5.5A1₁ = 180

A₁ = 32.7

A₂ = 32.7

C₁= 8.2
