The actual distance between two cities that are 3 7/8 inches apart on the map is 279 miles.

Step-by-step explanation:

To find the actual distance between two cities, we need to convert the distance on the map to miles. The scale of the map is 3/4 inch equals 72 miles, which means 1 inch on the map is equal to 72/3=24 miles.

So, the actual distance between two cities on the map that are 3 7/8 inches apart is 24 * 3 7/8 = 279 miles.

The offered statement states that there's 12 inches throughout 1 foot and 24 inches in 2 feet.

In the United States, Quebec, and the United Kingdom, the inch is a widely used conventional measure of length. In Japan, particularly for display screens, it is utilized for electrical components as well. The inch is also a commonly-used informal unit of measurement for display screens throughout most of continental Europe. Half, quarter, eighth, and sixteenths are the minor fractions that make up an inch. The size of both the line indicating each lowers as the sum or length does. Millimeters are used to divide centimeters (10 per centimeter).

In 1 feet there are 12 Inches.

12 inches/foot * 2 feet = 24 inches

So, 2 feet is equal to 24 inches.

Answer:

2^4*2^5=2^(4+5)=2^9

Step-by-step explanation:

When dealing with operations with exponents and multiplication, the exponent operations always come first.  So while the exponent 9 is correct for the answer, 4 is incorrect.

For example, if you were to solve each operation and eliminate every exponent, you would have

2^4*2^5=16*32=512 which is the same as 2^9=512.

As you can see, the exponent operation must come before the multiplication.

Of the lists of properties you provided, only the list of "identity, solubility, melting point" contains only those that are characteristic properties of a substance.

Identity refers to the name or chemical formula of the substance, which is unique to that substance and can be used to identify it.

Solubility refers to the ability of a substance to dissolve in a solvent, such as water. The solubility of a substance can also be used to identify it, as different substances have different solubility's.

Melting point refers to the temperature at which a solid substance will change into a liquid. Like solubility, the melting point of a substance is also a characteristic property that can be used to identify it.

On the other hand, boiling point, mass, and density are not always characteristic properties of a substance. While they can give us information about a substance, they are not unique to that substance and cannot be used to identify it.

Volume and temperature are not considered characteristic properties of a substance, as they are dependent on external factors, such as the pressure and the amount of the substance being measured.

Therefore , the solution of the given problem of function comes out to be the value of c for which f'(c) = 0 in the interval [-2, 2] is c = 0.

The study of numbers and their variable, as well as in out environment, architecture, and both real and imagined places, are all covered in the mathematics curriculum. A function range illustrates visually how the amounts of the inputs and the corresponding outputs for each are related. Simply stated, a function is a set of inputs that, when combined, produce specific outputs for each input. Each position is given a locale, region, or range.

Here,

Rolle's Theorem can be applied to $f(x) = x^2 - 3$ on the interval [-2, 2]. This is because f(x) satisfies the following conditions of Rolle's Theorem:

1 ) f(x) is continuous on the interval [-2, 2]

2 ) f(x) is differentiable on the interval (-2, 2)

3)  f(-2) = 1 and f(2) = 1

Since f(-2) = f(2), there must exist at least one point c in the interval (-2, 2) such that f'(c) = 0.

Taking the derivative of f(x) with respect to x, we get f'(x) = 2x. Setting f'(c) = 0, we have:

2c = 0

Solving for c, we get c = 0.

Therefore, the value of c for which f'(c) = 0 in the interval [-2, 2] is c = 0.

Note: The table shows the result of the equation H(x) = -x + 3 for different values of x.

Step-by-step explanation:

The number of trains that can accommodate 2 passengers is x = 32, the number of trains that can accommodate 3 passengers is y = 1, and the number of trains that can accommodate 5 passengers is z = -11.

It is represented by an equal sign (=) and consists of variables, numbers, and mathematical operations. Equations are used to describe relationships between different quantities and can be solved to find unknown values. For example, the equation 2x + 3 = 7 can be solved for x by subtracting 3 from both sides, giving 2x = 4, and then dividing both sides by 2, giving x = 2.

Let x, y and z be the number of trains that can accommodate 2 passengers, 3 passengers and 5 passengers, respectively.

From the information given, we have:

x + y + z = 20 (the total number of trains)

2x + 3y + 5z = 64 (the total number of passengers)

We also know that 10 trains were used during market day:

3 of the x trains, 2 of the y trains and 4 of the z trains.

So, we have:

2x + y + 5z = 10

Solving these three equations simultaneously, we can find the values of x, y and z:

Subtracting the first equation from the third equation:

0 + y + 4z = -10

y + 4z = -10

Subtracting 2 times the first equation from the second equation:

-x + 3y + 4z = 32

y + 4z = 42

Subtracting the last two equations:

x = 32

Substituting the value of x back into the first equation:

32 + y + z = 20

y + z = -12

Substituting the value of y and z back into the third equation:

2x + y + 5z = 10

64 + y + 5z = 10

y + 5z = -54

Solving these two equations simultaneously, we can find the values of y and z:

Subtracting the second equation from the last equation:

4z = -44

z = -11

Substituting the value of z back into the second equation:

y + 5z = -54

y - 55 = -54

y = 1

Therefore, the number of trains that can accommodate 2 passengers is x = 32, the number of trains that can accommodate 3 passengers is y = 1, and the number of trains that can accommodate 5 passengers is z = -11.

The child is paying out cord at a rate of s(ds/dt)) /√(s²-h²) feet per second when "s" feet of cord are out.

A differential equation is an equation that contains one or more functions with its derivatives.

The distance between the kite and the child's hand level "d".

By using the Pythagorean theorem, we can write:

d² + h² = s²

Simplifying and solving for d, we get:

d² = s²-h²

d = √(s²-h² )

Let's call the length of the cord "L". Then, we can write:

d² + L² = s²

Differentiating both sides with respect to time (t), we get:

2d (dd/dt) + 2L (dL/dt) = 2s (ds/dt)

We want to find (dL/dt) when L = s and d = √(s²-h² )

(dd/dt) = 0 as the height of the kite above the child's hand level is constant.

(dL/dt) = (s(ds/dt) - d (dd/dt)) / L

Substituting in the values we found for d and L, we get:

(dL/dt) = s(ds/dt)) / √(s²-h² )

Therefore, the child is paying out cord at a rate of s(ds/dt)) /√(s²-h²) feet per second when "s" feet of cord are out.

Hi there, here's your answer:

The general formula of a circle:

[tex](x-h)^{2} +(y-k)^{2}=r^2\\[/tex]

Where the ordered pair (h, k) is the center of the circle.

Given (h, k) = (-6, -2)

We also have that the circle passes through a point (7, 12)

Which means that (7, 12) lies on the circumference of the circle.

Let this be labelled as [tex](x_{1}, y_{1})[/tex]

Since this point lies on the circumference of the circle, it must satisfy the equation when substituted in for (x, y).

Thus, we substitute [tex]x_{1}[/tex] for x and [tex]y_{1}[/tex] for y.

We get the final equation to be:

[tex](7+6)^2 + (12+2)^2 = r^2[/tex]

Or

[tex]169 + 196 = r^2[/tex]

[tex]r^2 = 365[/tex]

We want to find the maximum number of miles that can be driven given a budget of $110, so we set 80 + 0.25x = 110 and solve for x:

80 + 0.25x = 110

0.25x = 110 - 80

0.25x = 30

The range of the function, given the graph of a relation, can be found to be −2 ≤ y ≤ 7 .

Graphs can be used to determine a function's domain and range. The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values. The y-axis on a graph represents the possible output values, or range.

The range here would therefore be the y - values that the relations fall within. The lowest y - value is - 2 as no relation goes below this. The highest y - value is 7.
