I would prefer leaving the answer as a radical number as √5 since it is a shorter form and exact form of the answer.

My reasons for leaving it as a radical form or a decimal approximation are;

1) If we are trying to find an exact answer, then we should leave it as √5. For example, if we are told a square has an area of 5 square units, then it means that the exact length of the side is √5 units.

2) If √5 is the length of an object that has to be made to that specific length, then we would require an approximation. For example, if you are asked to make a square out of cardboard whose area is 5 square feet, then we will definitely need an approximation of √5 ft = 2.24 ft, which would help us make each side of the cardboard square in the length of 2.24 ft.

Answer:

Step-by-step explanation:

you doubled the people, so you would need to double the flour.

The tower is 24 feet tall.

To solve this problem, we need to use the formula for the volume of a rectangular prism, which is V = l × w × h, where l and w are the length and width of the base and h is the height.

We are given that the side length of the base of the building is 100 feet less than the height of the building, so the height of the building is h = l + 100, where l is the side length of the base. We can substitute this expression for h into the formula for the volume of the building:

V = l × w × (l + 100) = 2 million cubic feet

Since the building is 25 times as tall as the tower, the height of the tower is h = (1/25) × h = (1/25) × (l + 100). Substituting this expression for h into the formula for the volume of the building, we get:

V = l × w × (1/25) × (l + 100) = 2 million cubic feet

Solving this equation for l, we find that l = 500 feet. This is the side length of the base of the building, so the height of the building is h = l + 100 = 500 + 100 = 600 feet. The tower is (1/25) × 600 = 24 feet tall.

The coefficient of determination (also known as the R-squared) is a measure of the proportion of the variance in the dependent variable (the y-variable) that is explained by the independent variable (the x-variable).

It is denoted by r-squared and typically takes values between 0 and 1. A value of 0 indicates that the independent variable does not explain any of the variance in the dependent variable, while a value of 1 indicates that the independent variable explains all of the variance in the dependent variable. The coefficient of determination (also known as the R-squared) is a measure of the proportion of the variance in the dependent variable (the y-variable) that is explained by the independent variable (the x-variable). A higher R-squared value indicates a stronger regression relationship between the two variables.

The number of independent pieces of information used to calculate a statistic is called the degrees of freedom, which is frequently denoted by the letters v or df. I

Itbis determined by subtracting the number of restrictions from the sample size. Subtract the number of relations from the number of observations to determine degrees of freedom. You need to deduct one (1) from the total number of observations, n, in order to calculate the degrees of freedom for a sample mean or average.

The degrees of freedom for the chi-square are calculated as df = (r-1)(c-1) where

r = the number of rows

c = the number of columns.

If the observed chi-square test statistic is greater than the critical value, the null hypothesis can be rejected.

To calculate the total interest that Lucy will have to pay, we need to use the formula for simple interest: I = P * R * T, where I is the interest, P is the principal (the amount borrowed), R is the interest rate (as a decimal), and T is the time in years. Using this formula, we can calculate the total interest that Lucy will have to pay as follows:

I = P * R * T

I = $4000 * 0.05 * 2

I = $400

Therefore, the total interest that Lucy will have to pay is $400.

________________________________________________________

To calculate the total repayment amount (including interest), we need to add the total interest to the original amount borrowed, which in this case is $4000. Therefore, the total repayment amount will be $4000 + $400 = $4400. This is the amount that Lucy will have to pay back to her parents at the end of the two-year period.

Step-by-step explanation:

Answer:

Total interest = $400

Total repayment (including interest) = $4,400

Step-by-step explanation:

Simple Interest Formula

[tex]\large\boxed{ \sf I = Prt}[/tex]

where:

Given:

To find the total interest, substitute the given values into the formula and solve for I:

[tex]\implies \sf I=4000 \cdot 0.05 \cdot 2[/tex]

[tex]\implies \sf I=200 \cdot 2[/tex]

[tex]\implies \sf I=400[/tex]

Therefore, the total interest Lucy has to pay is $400.

The total repayment amount is the sum of the principal and the interest:

[tex]\implies \sf A=P+I[/tex]

[tex]\implies \sf A=4000 +400[/tex]

[tex]\implies \sf A=4400[/tex]

Drag force is the net force in the direction of flow experienced by any item moving through a fluid and is caused by pressure and shear stress forces acting on the surface of the object.

Formula of drag force is given by:

[tex]F_d = \frac{1}{2}C_dAPv^2[/tex]

where

[tex]F_d[/tex] = drag force (N)

[tex]C_d[/tex] = drag coefficient (1.05 for moving car)

P = density of fluid (1.2 kg/m3 for air at NTP)

v = flow velocity (m/s)

A = characteristic frontal area of the body

A = height * width

=> 1.6*1.4

so A=2.24 [tex]m^2[/tex]

and v=10 m/s

so [tex]F_d[/tex] = 1/2* 1.05 * 2.24 *( 1.2 *10*10)

Answer:

The answer is x = -6 and y = -5.

Step-by-step explanation:

To solve this problem, we can use substitution. Let's first solve one of the equations in terms of the variable y, and then substitute this value into the other equation.

4x = 3y - 9

3y = 4x + 9

Since the term "3y" is present in the other equation given, we can substitute the right side of this equation (4x + 9) into the other equation for 3y. This is shown below.

6x - 3y = -21

6x - (4x + 9) = -21

6x - 4x - 9 = -21

We can simplify the left side of the equation and solve for x.

2x - 9 = -21

2x = -12

x = -6

Now, we can substitute this value for x into one of our equations to solve for y.

4x = 3y - 9

4(-6) = 3y - 9

-24 = 3y - 9

-15 = 3y

y = -5

Therefore, the correct answer is x = -6 and y = -5.

Therefore, [tex]$W(\mathbf{x})$[/tex] is a linear transformation.

To check whether [tex]$W(\mathbf{x})$[/tex] is onto:

Define the linear transformations:

[tex]$$T_1: \mathbf{R} \rightarrow \mathbf{R}$ such that $T_1(\mathbf{x})=\mathbf{x}$[/tex]

[tex]$$T_2: \mathbf{R} \rightarrow \mathbf{R}$ such that $T_2(\mathbf{x})=-\mathbf{x}$[/tex]

The range of both functions [tex]$T_1, T_2$ is $\mathbf{R}$[/tex] This is same as the co-domain of [tex]$T_1, T_2$[/tex]. So, they are onto functions.

If A and B are the two sets, if for every element of B, there is at least one or more element matching with set A, it is called the onto function.

Therefore, [tex]$T_1, T_2: \mathbf{R} \rightarrow \mathbf{R}$[/tex]are onto linear transformations.

And, [tex]$W=T_1+T_2: \mathbf{R} \rightarrow \mathbf{R}$[/tex] is a mapping.

[tex]$$\begin{aligned}& =T_1(\mathbf{x})-T_1(\mathbf{x}) \\& =0\end{aligned}$$[/tex]

So, the range of [tex]$$W(\mathbf{x})$ is $\{0\} \neq \mathbf{R}($[/tex] co-domain of [tex]$W(\mathbf{x}))$[/tex]

Then, is [tex]$W(\mathbf{x})$[/tex] not onto.

What is parasail?

A kind of sports game where a person climbs in a parachute and the parachute is tied to a moving motorboat.

Generally, parasail is tied with a motorboat by a special chord. The position of chord of parasail is not properly perpendicular to the direction of boat moving on. There is an angle between the chord and horizontal surface of motorboat.

Let the angle is denoted by β

The vertical height of parasail over the boat=h

the length of chord that means distance from boat to the parasail = y

speed of boat = X

As per trigonometric formula, opposite/ hypotenuse = sinβ

                                        sinβ = h/y

   hence, height of parasail over the boat surface, h= y sin β

                             Now, from the height, speed and time equation
