Explanation:

We'll need to find the LCM of 5, 8 and 10.

List out the prime factorization of the three numbers.

The unique prime factors are 2 and 5. The '1' isn't a prime number, so we can ignore it.

The '2' has an exponent of 3 as the largest exponent, meaning 2^3 is part of the LCM. The '5' has the largest exponent of 1. So 5^1 = 5 is also part of the LCM

LCM = 2^3*5 = 8*5 = 40

List out the multiples of 40

40, 80, 120, 160, ...

The number 80 is the only multiple between 61 and 107

We need to use the concept of Plotting of Graphs.

A.(2018,62) and (2022,74) are the given points.

B. Slope=3

C. Height of Deshaun will increase 3 inches per year.

You must comprehend how the coordinate plane is organized and be aware of what to do with those (x, y) coordinates in order to graph points on the coordinate plane. Simply follow these instructions to learn how to graph points on the coordinate plane. You will graph a point in (x, y) form when you are graphing it on the coordinate plane. What you must understand is as follows:

The second coordinate is on the y-axis, while the x-axis runs left to right.

The y-axis is oriented vertically.

Positive numbers increase or move right (depending on the axis). Negative numbers move to the left or down.

Slope of a line segment=y2-y1/x2-x1 where (x1,y1) and (x2,y2) are the given points.

2018, Deshaun was 62 inches tall.

2022, Deshaun was 74 inches tall.

So assume the age on X-axis and Height on Y-axis.

A)Label the points we could use to find slope from this information:

  (2018,62) and (2022,74).

B) We know that,

    Slope=y2-y1/x2-x1

    ⇒Slope=(74-62)/(2022-2018)

    ⇒ Slope=12/4

    Slope=3.

C) As per the given slope, the height of Deshaun will increase 3 inches per year.

We need to use the concept of Plotting of Graphs.

To transform the regression equation, you would divide both sides of the equation by the square root of Var(ut), which is σ√(zt). This transformation helps in obtaining the transformed regression coefficients and standard errors that account for the heteroscedasticity in the error term.

When the variance of the error term (ut) is related to a known variable (zt), it implies the presence of heteroscedasticity in the regression model. Heteroscedasticity means that the variability of the error term is not constant across different levels of the independent variables.

To address this issue, we can transform the regression equation by dividing both sides by the square root of the variance of the error term, which is σ√(zt). This transformation is known as the weighted least squares (WLS) estimation.

By dividing both sides of the equation, we can obtain the transformed regression equation with the error term divided by its standard deviation. This transformation accounts for the heteroscedasticity by giving different weights to the observations based on the variability of the error term. It allows for a more appropriate estimation of the regression coefficients and standard errors, as it gives more weight to observations with smaller error variances and less weight to observations with larger error variances.

Refer to the equations for a limaçon:

This is an inner loop limaçon because 36/70<1, so its horizontal axis intercepts are 36 and -36 (marked in red) and its vertical axis intercepts are 0, 36+70=106 and 70-36=34 (marked in green)

So after one hour, the amount of chlorine in the tank has decreased from 20 g to 8.6 g using differential equation.

Let's start by finding the initial amount of chlorine in the tank:

The tank has a capacity of 400 liters and a concentration of 0.05 g of chlorine per liter, so the initial amount of chlorine in the tank is:

400 liters * 0.05 g of chlorine per liter = 20 g of chlorine

Next, we can set up a differential equation to describe how the amount of chlorine in the tank changes over time. We know that the concentration of chlorine in the tank is being diluted by the addition of fresh water at a rate of 4 liters per second, and being removed from the tank at a rate of 10 liters per second. Let C(t) be the amount of chlorine in the tank at time t, in grams. Then we have:

dC/dt = (0.05 g/L * 4 L/s) - (C(t)/400 L * 10 L/s)

The first term on the right-hand side represents the rate at which chlorine is being added to the tank, and the second term represents the rate at which chlorine is being removed from the tank. The factor C(t)/400 L represents the concentration of chlorine in the tank at time t.

We can simplify this equation by multiplying through by 400 L and rearranging:

dC/dt = 2 - (5/2) * C(t)

This is a first-order linear ordinary differential equation. We can solve it using separation of variables:

dC/(2 - (5/2) * C) = dt

Integrating both sides:

(-2/5) * ln|2 - (5/2) * C| = t + constant

Solving for C:

\(C(t) = (2/5) * (2 - e^{(-5t/2)})\)

Now we have a formula for the amount of chlorine in the tank as a function of time. To find the amount of chlorine in the tank at a particular time, we can substitute that time into the formula for C(t). For example, to find the amount of chlorine in the tank after 1 hour (3600 seconds), we can calculate:

\(C(3600) = (2/5) * (2 - e^{(-5/2 * 3600)})\)

\(= (2/5) * (2 - e^{(-9000)})\)

≈ 8.6 g

Answer:

Long solution

Step-by-step explanation:

(a) Let the height of the cone be h cm. The volume of the hemisphere is given by (1/2)(4/3)πr³ = (2/3)πr³. The volume of the solid is the sum of the volumes of the hemisphere and the cone, which is (2/3)πr³ + (1/3)πr²h. Since the volume of the hemisphere is one third of the volume of the solid, we have:

(2/3)πr³ = (1/3)πr²h

Simplifying, we get:

2r = h

Therefore, h is expressed in terms of r as h = 2r.

(b) The slant height of the cone can be found using the Pythagorean theorem. Let l be the slant height, then we have:

l² = r² + h²

Substituting h = 2r, we get:

l² = r² + (2r)² = 5r²

Taking the square root of both sides, we get:

l = r√5

Since k is an integer, we can write:

l = Vk cm, where k is an integer

Comparing the two expressions, we get:

Vk = r√5

Therefore, the value of k is k = ⌊r√5⌋, where ⌊x⌋ denotes the largest integer less than or equal to x.

(c) The total surface area of the solid is the sum of the curved surface area of the cone, the curved surface area of the hemisphere, and the area of the circular base of the cone. We have:

Curved surface area of the cone = πr l = πr(r√5) = πr²√5

Curved surface area of the hemisphere = 2πr²

Area of the circular base of the cone = πr²

Therefore, the total surface area of the solid, in cm², is given by:

πr²√5 + 2πr² + πr² = (πr²)(√5 + 3)

The order of T is 82.

Let n and e be the order and number of edges of T respectively.

Also, let a, b, c and d be the number of vertices of degree 2, 3, 4 and 5 respectively.

Then, 50+a+b+c+d = n

And by the Handshake Lemma,  the sum of the degrees of all the vertices of T is twice the number of edges, so we have

50+2a+3b+4c+5d = 2e

Since a=b=c=d then we have the following two equations,

50+4a = n

50+14a = 2e

But, T is a tree so e=n=1, then the two equations become,

50+4a = n ...............(1)

50+14a = 2(n-1) .............(2)

Solving for a in (1) we get,

a = \(\frac{n-50}{4}\)

Plugging a into (2) we get,

50+14(\(\frac{n-50}{4}\)) = 2(n-1)

50+3.5n-175 = 2n-2

3.5n-2n = 175-50-2

1.5n = 123

n = \(\frac{123}{1.5}\) = 82

The surface area of the triangular prism 5ft 11ft 15 ft is 515 sq ft.

To find the surface area of a triangular prism, we need to calculate the area of each face and then add them together.

The triangular base has dimensions of 5ft and 15ft, so its area is:

Area of triangular base = (1/2) x 5ft x 15ft = 37.5 square feet

There are two identical triangular faces, so the total area of the triangular faces is:

Total area of triangular faces = 2 x 37.5 = 75 square feet

The rectangular faces have dimensions of 5ft x 11ft and 11ft x 15ft, so their areas are:

Area of first rectangular face = 5ft x 11ft = 55 square feet

Area of second rectangular face = 11ft x 15ft = 165 square feet

There are two identical rectangular faces, so the total area of the rectangular faces is:

Total area of rectangular faces = 2 x (55 + 165) = 440 square feet

Hence, the triangular prism's total surface area is:

Total surface area = Total area of triangular faces + Total area of rectangular faces

Total surface area = 75 + 440 = 515 square feet

The triangular prism offered has a surface area of 515 square feet.
