The speed of wind is 380 miles per hour.

What is speed?

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is traveling along a path.

Here, we have

The plane has a cruising speed of 200 miles per hour when there is no wind. at this speed, the plane flew 500 miles with the wind in the same amount of time it flew 300 miles against the wind.

We have to find the speed of the wind.

Time = Distance/speed

Time = 500/200 = 2.5hrs

When the plane moves against the wind its effective speed reduces as it has to overcome the opposing force of the wind since it is given that it cover's a distance of 300 miles at the same time we can write

2.5 = 300/ V(plane) - v(wind)

2.5 = 300/500- v(wind)

v(wind) =380mph

Hence, the speed of the wind is 380mph.

Answer:

Step-by-step explanation:

1.Φ(u,v) gives the parametrization with its x, y, and z components. So, x=7u+4, y=u-v, and z=13u+v. We can use this to get the tangent vectors by taking the respective partial derivatives. Tu=<7, 1, 13> by taking the u derivatives of the components and Tv=<0, -1, 1> by taking the v derivatives of the components.

2. Taking the cross product of Tu and Tv will give the normal vector n(u,v), which is <14, -7, -7>

3. To find Area(S), you have to multiply the area of D by the magnitude of the normal vector from the previous step. D is the region defined by 0<=u<=5 and 0<=v<=6, so the area of D is 5*6=30. Multiply this by the magnitude of the normal vector to find that Area(S)=30sqrt(294)

4. To integrate, we first must put the initial function in terms of the parameters we found in the first step. Replace y with u-v and z with 13u+v. Next, multiply this integrand by the magnitude of the normal vector (sqrt294) and apply the given bounds for u (0<=u<=5) and v (0<=v<=6). From here the problem can be integrated like any other double integral, the final answer being 190sqrt(294)

An equation which describe the function g(x) after reflecting the graph of function f(x)=2|x| over the x-axis is: C. g(x) = −2|x|. g begin argument x end argument equals negative 2 begin absolute value x end absolute value.

In Geometry, a reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.

In Mathematics, a reflection across the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would change from positive to negative. Therefore, a reflection across the x-axis is given by this transformation rule: (x, y)  →  (x, -y).

By applying a reflection across the x-axis to the function, we have;

f(x) = 2|x|

g(x) = -f(x)

g(x) = -(2|x|)

g(x) = -2|x|

After 9 hours, Singer A and Singer B will both charge the same amount.

An equation in French is defined as having one or more variables, whereas an equation in English is any well-formed formula consisting of two expressions combined with an equals sign.

Solving a variable equation includes determining which variables' values result in equality. Unknowns are the variables for which the equation must be solved, while equation solutions are the unknown values that satisfy the equality. An equation is a mathematical phrase with two equal sides separated by an equal sign. An equation is 4 + 6 = 10. We can see 4 + 6 on the left side of the equal sign and 10 on the right.

The Singer A's initial fee is $50.

Singer A's hourly rate is $10.

Singer B's initial fee was $95

Singer B's hourly wage is $5.

Assume the duration after which both singers will charge the same amount = x.

Then 50 +10x =95+5x

10x-5x=95-50

5x=45

x=45/5

x=9 hours

So, after 9 hours, Singer A and Singer B will both charge the same amount.

The percent of the wall does she paint will be;

⇒ 79%

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The length of room wall = 8 feet

The width of room wall = 12 feet

The length of windows = 5 feet

The width of windows = 2 feet

Now,

The area of wall = 12 x 8 feet²

                         = 96 feet²

And, The area of windows = 5 x 2 feet²

                                         = 10 feet²

Hence, The area of paints a wall in her bedroom = 96 - 2 (10)

                                                                            = 96 - 20

                                                                            = 76 feet²

So, She paint the wall of area 76 feet².

Since, The area of whole wall = 96 feet²

But, There are two window.

So, The percent of only wall paint of are 76 feet² = 100 x 76 / 96

                                                                            = 79.16%

Thus, The percent of the wall does she paint to the nearest whole percent will be;

The SI unit for density is kilogram per cubic meter (kg/m³)/

The density of liquid is 0.17 × 10⁸.

Kilogram Per Cubic Meter:

The SI unit for density is the kilogram per cubic meter (kg/m3). For many situations, however, this as an inconvenient unit, and we often use grams per cubic centimeter (g/cm3) for the densities of solids and liquids, and grams per liter (g/L) for gases.

According to the question:

Firstly, have to change your units to kilograms and cubic meters. Since there are a thousand grams in a kilogram,

                        170g = 1.70 x 10⁻¹ kg.

Since there are a thousand milliliters in a liter and a thousand liters in a cubic meter

               100ml = 1.00 x 10⁸ cubic meters

Therefore, Density= mass/volume

Density = 1.7 x 10⁻¹/ 1.00 x 10⁸ kg/m³

i = a*x1i + b*x2i + c

Where i is the annual revenue

a is the coefficient of x1i which is distance from CBD

where b is the coefficient of x2i average price of a dish

C is the constant term.

Given that moving one mile away from the CBD x1i , the annual revenues will i will decrease by $60000. So, the coefficient of x1i, a is -60000

Given that increasing the average price of dish x2i by $1 , the annula revenue will i will increase by $40000. So the coefficient of x2i, b is 40000

The data shows  that the restaurant at the center of the CBD which means, x1i = 0 and giving away its food for free which means x2i = 0 is resulting in a loss of $20000. so the value of the constant term is c=20000.
