Answer:

It depends on the syntax of the expression.

Step-by-step explanation:

There are many ways to write this unit conversion (dimensional analysis).

Here's one way:

\(\dfrac{75 \, \textrm{beats}}{1 \, \textrm{min}} \times \dfrac{60 \, \textrm{min}}{1 \, \textrm{hr}} \times \dfrac{24 \, \textrm{hr}}{1 \, \textrm{day}} \times \dfrac{365 \, \textrm{days}}{1 \, \textrm{year}} \times 10\)

And here's another:

\(10 \times \dfrac{75 \, \textrm{beats}}{1 \, \textrm{min}} \times \dfrac{75 \, \textrm{min}}{1.25 \, \textrm{hr}} \times \dfrac{8,760 \, \textrm{hr}}{1 \, \textrm{year}} \times \dfrac{\dfrac{4}{5}}{\dfrac{4}{5}}\)

But the expected answer is probably:

By differentiating the function x = Acosh(wt) + Bsinh(wt) twice and substituting it into the differential equation x'' - w^2 * x = 0, we can calculate that x'' = -Aw^2cosh(wt) - Bw^2sinh(wt) and w^2 * x = w^2 * (Acosh(wt) + Bsinh(wt)), resulting in x'' - w^2 * x = 0.

To verify that the function x = Acosh(wt) + Bsinh(wt) satisfies the differential equation x'' - w^2 * x = 0, we differentiate x twice and substitute it into the equation.

First, we find x' (the first derivative of x):

x' = Awsinh(wt) + Bwcosh(wt).

Next, we find x'' (the second derivative of x):

x'' = Aw^2cosh(wt) + Bw^2sinh(wt).

Substituting x'' and x into the differential equation x'' - w^2 * x = 0, we have:

(Aw^2cosh(wt) + Bw^2sinh(wt)) - w^2 * (Acosh(wt) + Bsinh(wt)).

Expanding and simplifying, we get:

Aw^2cosh(wt) + Bw^2sinh(wt) - Aw^2cosh(wt) - Bw^2sinh(wt) = 0.

This simplifies to:

0 = 0.

Therefore, by differentiating the function x = Acosh(wt) + Bsinh(wt) and substituting it into the differential equation x'' - w^2 * x = 0, we have shown that x'' = -Aw^2cosh(wt) - Bw^2sinh(wt) and w^2 * x = w^2 * (Acosh(wt) + Bsinh(wt)), resulting in x'' - w^2 * x = 0.

The intersection of the labor supply and demand curves determines the equilibrium wage rate and quantity of labor.

The labor supply and demand curves are used to analyze the market of labor, where the demand is the amount of labor that employers are willing to hire at a given wage, and the supply is the amount of labor that individuals are willing to supply at a given wage. The labor supply curve is upward sloping and shows the quantity of labor supplied at different wages. Mathematically, this is represented as the equation: Qs = a + bw, where Qs is the quantity of labor supplied, a is a constant, b is the elasticity of labor supply, and w is the wage. The labor demand curve is downward sloping and shows the quantity of labor demanded at different wages. Mathematically, this is represented as the equation: Qd = c – dw, where Qd is the quantity of labor demanded, c is a constant, d is the elasticity of labor demand, and w is the wage.

What is Trigonometry?

Trigonometry is the study of angles and the angular relationships of planar and three-dimensional shapes. Trigonometry is made up of trigonometric functions (also known as circle functions) such as cosecant, cosine, cotangent, secant, sine, and tangent.

The height of the tree can be calculated using trigonometry.

Let's call the height of the tree "h".

Then, using the right triangle formed by the height of the tree, the distance from the base of the tree to where Jerome is standing, and the angle between the ground and the top of the tree, we can set up the following equation:

tan(33°) = h / 90

Solving for h, we get:

h = 90 * tan(33°)

Using a calculator to find the value of tan(33°), we get:

h = 90 * 1.730

h ≈ 156.7 feet

Answer:

x = 7

Step-by-step explanation:

(x+2)+(3x-9)+(2x+1) = 36

6x - 6 = 36

6x = 42

x = 7

The expression is equivalent to "\(z^4 * (z + 6)^2 + (z + 6)\)".

To clarify, I understand the expression as: "z * (z + 6) * z * (z + 6) * z + (z + 6)". Let's break down the expression and simplify it step by step:

Distribute the multiplication:

z * (z + 6) * z * (z + 6) * z + (z + 6)

becomes

z * z * z * (z + 6) * (z + 6) * z + (z + 6)

Combine like terms:

z * z * z simplifies to \(z^3\)

(z + 6) * (z + 6) simplifies to (z + 6)^2

The expression now becomes:

\(z^3 * (z + 6)^2 * z + (z + 6)\)

Multiply \(z^3\) and z:

 \(z^3 * z\) simplifies to \(z^4\)

The expression becomes:

  \(z^4 * (z + 6)^2 + (z + 6)\)

So, an equivalent expression to "z (z + 6)z (z + 6)z + (z + 6)" is "\(z^4 * (z + 6)^2 + (z + 6)\)".

The probability that the mean lifetime of 25 randomly selected tires of this type will exceed than 42,000 miles is 25.14.

To break this problem, we need to use the standard normal distribution, assuming that the distribution of tire continuances is roughly normal. We can regularize the value of 42,000 using the formula

z = ( x- μ)/ σ

where x is the value of interest( 42,000 long hauls), μ is the mean tire continuance( 40,000 long hauls), and σ is the standard deviation( 3,000 miles). Plugging in the values, we get

z = ( 42,000- 40,000)/ 3,000 = 0.67

Using a standard normal distribution table or calculator, we can find the probability that an aimlessly named tire will last further than 42,000 long miles by looking up the area to the right of z = 0.67 under the standard average wind. This probability is roughly 25.14.

thus, the probability that a tire named arbitrarily from this brand will last more than 42,000 miles is roughly 25.14.

Therefore, the relative accuracy of features plotted on the map is 500 meters.

To calculate the relative accuracy of features plotted on the map in meters, we need to convert the given accuracy from millimeters to meters.

Given:

Relative accuracy = 90%

Accuracy within 5 mm

To convert millimeters to meters, we divide by 1000:

5 mm = 5/1000 = 0.005 meters

Relative accuracy can be defined as the ratio of the actual accuracy to the map scale. In this case, the map scale is given as 1:100,000, which means that one unit on the map represents 100,000 units in reality.

To calculate the relative accuracy in meters, we multiply the actual accuracy (0.005 meters) by the map scale (100,000):

Relative accuracy = 0.005 meters * 100,000 = 500 meters

Answer:

625.5 cm^2

Step-by-step explanation:

The volume of a cone is

V = 1/3 B h

4170 = 1/3 B 20

4170 = 20/3 B

Multiply each side by 3/20

4170 *3/20 = B

625.5 = B

Hey there! I'm happy to help you!

The formula for the volume of a cone is V=1/3(πr²h). Now, to make it look ungibberishy and all numbery...

The volume of the cone is equal to the area of the base (the circle on the bottom whose area formula is pi multiplied by the radius squared) multiplied by the height and then divided by three.

In our case, though, we already have the volume. We need to undo the equation so that we can find the area of the circle base.

In our equation the last thing we do is divide by three. So, we will want to multiply by three to undo this.

4,170*3= 12510

The other step we took was multiply the base by the height, which is 20 centimeters.  To get our base, we will divide by the height instead!

12510/20= 625.5

Therefore, the area of the base of the cone is 625.5 centimeters squared.

Answer:

(12,0) and (3, -1) and (0,-4/3)

Step-by-step explanation:

To find if a point makes an equation true, just substitute its x and y values in in the equation and simplify.

1) Let's test the point (12,0). Substitute 12 for x and 0 for y in the equation:

\(x-9y=12\\(12)-9(0)=12\\12-0=12\\12=12\)

12 does equal 12, so (12,0) makes the equation true.

2) Let's test the point (0, 12). Substitute 0 for x and 12 for y in the equation:

\(x-9y=12\\(0)-9(12) = 12\\0-108 = 12\\-108 = 12\)

However, -108 does not equal 12, so (0,12) does not make the equation true.

3) Let's test the point (3, -1). Substitute 3 for x and -1 for y in the equation:

\(x-9y=12\\(3)-9(-1) = 12\\3 + 9 = 12\\12 = 12\)

12 does equal 12, so (3, -1) makes the equation true.

4) Let's test the point (0, -4/3). Substitute 0 for x and -4/3 for y in the equation:

\((0) -9(-\frac{4}{3} ) = 12\\0 + \frac{36}{3} = 12\\0 + 12 = 12 \\12 = 12\)

12 does equal 12, so (0, -4/3) makes the equation true.

The integral is equal to zero, since the divergence of a constant vector is always zero.

The integral ∫ (∇ × a® ).® is equal to zero. This is due to the fact that the curl of a constant vector is always zero. The vector a® is given to be eˆ eˆ eˆ, therefore it is a constant vector. Since the divergence of a constant vector is always zero, the integral is equal to zero.

To further illustrate this point, we can expand the integral in terms of its components. ∇ × a® is equal to 0 as it is the curl of a constant vector. Similarly, a® .® is equal to 0 since the inner product of two constant vectors is always zero. Therefore, the integral is equal to 0.

The surface defined by the paraboloid is not used in this calculation, as the surface does not affect the value of the integral. The surface is used to define the range of the integral, but not to calculate the value of the integral itself.

The scale factor of the dilation is sqrt(14165) / 97.

the original line has a slope of 4/9, which means that for every increase of 9 units in the x-coordinate, the y-coordinate increases by 4 units. so the line passes through the point (9, 4) and (0, -4).

the image of the line after dilation is given by y= 9/4x−8, which also passes through the point (9, 4) and (0, -8).

since the dilation is centered at the origin, the distance between the origin and the point (9, 4) should be scaled by the same factor as the distance between the origin and the point (9, -8).

the distance between the origin and (9, 4) is given by the pythagorean theorem:

d1 = sqrt(9² + 4²) = sqrt(81 + 16) = sqrt(97)

the distance between the origin and (9, -8) is:

d2 = sqrt(9² + (-8)²) = sqrt(81 + 64) = sqrt(145)

the scale factor of the dilation is the ratio of these distances:

scale factor = d2 / d1 = sqrt(145) / sqrt(97)

rationalizing the denominator, we get:

scale factor = (sqrt(145) / sqrt(97)) * (sqrt(97) / sqrt(97))

The composite function (c . g)(18) has a value of 19352

The interpretation is that the total cost of 18 guest is $19352

From the question, we have the following parameters that can be used in our computation:

The cost per guest function c(x) = 200 + 2x.

The number of guest function g(x) = 100 - x

The composite function (c . g)(18) is calculated as

(c . g)(x) = c(x) * g(x)

Substitute the known values in the above equation, so, we have the following representation

(c . g)(x) = (200 + 2x) * (100 - x)

Substitute 18 for x in the above equation

This gives

(c . g)(18) = (200 + 2 * 18) * (100 - 18)

(c . g)(18) = 19352
