The population of winbug beetles in 1990 was 35,000. The population each year after 1990 is shown by the equation below.
P(t) = 6,000 + 29,000(1 + 0.031)^t
Which of the following best describes what will happen to the population of winbug beetles in the years after 1990?

A) As t approaches positive infinity, P(t) approaches zero
B) As t approaches positive infinity, P(t) approaches positive infinity.
C) As t approaches positive infinity, P(t) approaches negative infinity.
D) As t approaches positive infinity, P(t) remains constant.

Answers

Answer 1

B) P(t) increases as t increases toward positive infinity.

An exponent is what?

The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.

The population of winbug beetles after t years from 1990 is represented by the expression P(t) = 6,000 + 29,000(1 + 0.031)t.

We can see that when t grows, the exponential growth factor (1 + 0.031)t will eventually reach positive infinity. This implies that as t approaches positive infinity, the population of winbug beetles will similarly increase.

Consequently, the following is the best prediction of what will occur to the winbug beetle population in the years after 1990.

How to solve the exponential inequality?

The exponential inequality for this problem is defined as follows:

3^(4x - 5) < 8.

The number 8 is not a base of 3, hence the way to isolate the variable x is applying the log of base 3 to both sides, as follows:

What is Standard Deviation ?

It is a measure of how evenly distributed numbers are. It is the square root of the Variance, which is the average of the squared deviations from the Mean.

To find the sample standard deviation, first, we have to find the mean of the data, then subtract each data point from the mean, square each deviation, sum them, divide by the sample size minus 1, and then take the square root of the result.

Here's the calculation:

Mean = (1 + 5 + 12 + 16 + 15 + 12 + 19 + 5 + 10) / 9 = 11

Deviations = [-10, -6, 1, 5, 4, 1, 8, -6, -1]

Squared deviations = [100, 36, 1, 25, 16, 1, 64, 36, 1]

Sum of Squared deviations = 239

Sample Variance = Sum of Squared deviations / (Sample size - 1) = 239 / (9 - 1) = 239 / 8 = 29.875

[tex]Sample \ Standard\ Deviation=\sqrt{(Sample Variance)} \\\\Sample \ Standard\ Deviation=\sqrt{29.875}\\\\ Sample \ Standard\ Deviation= 5.9[/tex]

Answers

The equation in x and y whose graph is the path of the particle is y = (x - 4)2 + 5. The velocity vector at t= 4 is v(4) = i + 8j.

What is vector?

A vector in mathematics is a quantity that not only expresses magnitude but also motion or position of an object in relation to another point or object. Euclidean vector, geometric vector, and spatial vector are other names for it.

In mathematics, a vector's magnitude is defined as the length of a segment of a directed line, and the vector's direction is indicated by the angle at which the vector is inclined.

Given r(t) as r(t) = x(t)i + y(t)j

Thus, this means that:

x = t+ 4         y = t2 + 5      

We see that we can solve t as:            

t = x - 4, thus:

y = (x - 4)2 + 5

v(t) is given by r'(t).

r'(t) = v(t) = i + 2tj                      

at t = 4:

v(4) = i + 8j

The acceleration is given by:  r"(t).

a(t) = r"(t) = 0i + 2j

The acceleration at t = 4 is:

a(4) = 0i + 2j

Explain the relation of pressure, density, and temperature in the troposphere.

Pressure altitude is temperature-adjusted density altitude.

In simple terms, it has a direct impact on an aircraft's performance parameters and is essentially the height at which the aircraft "thinks" it is performing. The performance of an airplane decreases with increasing density altitude and vice versa.

Pressure and temperature have a direct and indirect relationship with density.

Density rises as pressure rises and temperature remains constant. Conversely, density falls as temperature rises while maintaining the same pressure. For every 10 hPa decrease in pressure or 3 °C rise in temperature, the air density will drop by around 1%.

The double integral of (xy y^(-2)) over the region R is equal to 0.

What is double integral ?

The term integral in math is defined as a method of adding or summing up the parts to find the whole and it is basically used to find the volume, area and the central values of many things. Double integrals are a two-dimensional integration method.

The given expression is the integrand of a double integral over the region R defined by the constraints 0 ≤ x ≤ 2 and 0 ≤ y ≤ 2. To calculate this double integral, we would evaluate the following expression:

∬(xy y^(-2)) dA = ∬(xy y^(-2)) dx dy over the region R

We can evaluate this double integral using a change of variables, such as polar coordinates, or using rectangular coordinates.

In rectangular coordinates, we can evaluate the double integral using the following steps:

Evaluate the bounds of integration:

x: 0 to 2

y: 0 to 2

Evaluate the integral with respect to y first, keeping x fixed:

∬(xy y^(-2)) dx dy = ∫(x ∫(y y^(-2)) dy) dx, from 0 to 2

Evaluate the inner integral with respect to y:

∫(y y^(-2)) dy = -y^(-1) = -ln(y) + C, where C is an arbitrary constant

Substitute the solution for the inner integral back into the outer integral:

∫(x (-ln(y) + C)) dx = x(-ln(y)) - xC + D, where D is another arbitrary constant

Evaluate the outer integral with respect to x:

∫(x(-ln(y)) - xC + D) dx = (-x^2/2)ln(y) - (x^2/2)C + xD + E, where E is yet another arbitrary constant

Evaluate the constants of integration C, D, and E using the boundaries of integration for x and y:

-ln(2) - 0C + 0D + E = 0

-2ln(2) - 2^2/2 C + 2D + E = 0

Solving the system of equations, we find C = 2ln(2), D = 0, and E = 0

Substitute the values of C, D, and E back into the solution:

(-x^2/2)ln(y) - (x^2/2)C + xD + E = (-x^2/2)ln(y) - x^2ln(2)

Finally, evaluate the integral over the region R by substituting the bounds of integration for x and y:

(-2^2/2)ln(2) - 2^2ln(2) = -4ln(2) + 4ln(2) = 0

So, The double integral of (xy y^(-2)) over the region R is equal to 0.

Answers

5.385 is the length of each line segment according to the Pythagoras theorem and distance formula.

what is Pythagoras theorem ?

The basic Geometric mathematical relationship between one right triangle's three sides is termed as the Pythagorean Theorem, or simply the Pythagorean Theorem. This rule states that the areas with squares with the two parts added together equal the area of the square well with hypotenuse side. The Pythagorean Theorem says that the square that crosses the tangent of a right angled triangle opposite the right angle equals the total of the squares that span the sides of something like a right triangle. It is sometimes written as the generic geometric notation a2 + b2 = c2.

given

A2 + B2 = C2 is a Pythagorean theorem.

Let C be the point (-2,1)

A two-unit line segment AC would be required.

The length of line segment BC would be 5 units.

Incorporate the line segment length into the Pythagorean theorem by adding

2^2 + 562

= 4 + 25

= 29

≅5.385.

5.385 is the length of each line segment according to the Pythagoras theorem and distance formula.

the _____ of a square are both congruent and perpendicular.

Answers

The diagonals of a square are both congruent and perpendicular.

Because a square is a regular quadrilateral with four equal sides and four equal angles, it is a quadrilateral. A rectangle with two adjacent sides of equal length can also be used to describe it. A chess board, dice, tiles, napkins, etc. are a few examples.

The perpendicular bisectors of a square's diagonals are one another. Each diagonal is divided into two congruent parts as a result, and their intersection creates four right angles. As a result, if a diagonal is given, its length, one segment's length is equal to half of the diagonal's overall length. They are also divided at a 90-degree angle, making them perpendicular, and they are similar in length.

Which one of the following is a statistically valid reason for sampling randomly when choosing subjects for a study?Correct Response- Sampling randomly tends to reduce sampling bias or risk- Sampling randomly (with a large sample) gives a perfect reflection of the population- Sampling randomly is easier than sampling nonrandomly- Actually, there is no statistically valid reason for sampling randomly

Answers

Sampling randomly is considered a statistically valid reason for choosing subjects for a study as it reduces the risk of sampling bias. The correct option is a.

Sampling bias refers to a systematic error that occurs in the process of selecting subjects for a study, leading to a sample that is not representative of the population.

By selecting subjects randomly, researchers aim to eliminate any preconceived biases or preferences that may influence the selection process. This leads to a sample that is more representative of the population, providing a more accurate representation of the population's characteristics.

Furthermore, random sampling (with a large sample) has the potential to give a perfect reflection of the population, assuming that the sample size is large enough. This is because, as the sample size increases, the sample becomes more representative of the population and tends to exhibit the same characteristics and distributions as the population.
