For the solid with square cross-sections, the integral that represents its volume is ∫ab​(f(x))2dx. Therefore, the integral ∫ab​(f(x))^2dx represents the volume of the solid with square cross-sections, and the integral ∫ab​π(f(x))^2dx represents the volume of the solid formed by rotating the region around the x-axis.

For the solid with square cross-sections, we want to calculate the volume. Each cross-section is a square with side length equal to the value of f(x). Therefore, the area of each cross-section is (f(x))^2. To find the volume, we integrate the area function over the interval from x = a to x = b, resulting in the integral ∫ab​(f(x))^2dx.

For the solid formed by rotating the region around the x-axis, each cross-section is a circle with radius equal to the value of f(x). The area of each cross-section is given by π(f(x))^2. To find the volume, we integrate the area function over the interval from x = a to x = b, resulting in the integral ∫ab​π(f(x))^2dx.

Answer:

  does not exist

Step-by-step explanation:

The notation f^-1(x) usually refers to the inverse function. That is, if we have the functional relation

  y = f(x)

Then the inverse function f^-1(x) will give you ...

  x = f^-1(y)

__

In order for an inverse function to exist, the original function must pass the "horizontal line test." That is, any horizontal line can intersect the function's graph in, at most, one point.

Here, the function f(x) = 245 is a horizontal line, so the horizontal line test fails. The horizontal line at y=245 will intersect f(x) in an infinite number of points.

So, f(x) = 245 does not have an inverse function. f^-1(x) does not exist.

_____

Alternate interpretation of the question

Sometimes, an exponent is applied to a function name when the intended operation is application of the exponent to the function value. For example, you may see sin²(x) when the intended meaning is sin(x)². The application of an exponent to the function name could be confused with multiple applications of the function: sin²(x) = sin(sin(x)), as the notation is sometimes used for this purpose, too.

If what you intend by f^-1(x) is really f(x)^-1, then you can say ...

  f(x)^-1 = 1/245

The slope of the line is  m = 14 / 17

The chance to not hit the target is 65 percentage. This means that there is a 65% chance that the hunter will miss the target.

The percentage of a hunter to hit a target is .35, which means that there is a 35% chance that the hunter will hit the target. This leaves a 65% chance that the hunter will miss the target. This means that there is a 65% chance that the hunter will not hit the target. This percentage is determined by the accuracy of the hunter, the size of the target, and any other external factors that may affect the accuracy of the hunter's shot. Accuracy is determined by the hunter's skill, experience, and the quality of the equipment used. The size of the target is also a factor, as it can be harder to hit a smaller target. Additionally, any environmental factors present, such as wind or rain, can cause the shot to go astray. All of these factors combine to determine the chance that the hunter will have to make or miss the target.

Answer:

Exponential decay

Step-by-step explanation:

The general form of an exponential function is

\(P=P_{0}a^t\), where P0 is the initial value, a is the base, and t is the exponent.

In your example, P0 is 1 and a is 4/5.

A function is experiencing exponential growth when a > 1.

A function is experiencing exponential decay when 0 < a < 1.

4/5 lies between 0 and 1, so the function is experiencing exponential decay.

Answer:

(a): Negative relationship

(b): 70 km

(c): It is the starting point where the bicyclist starts cycling.

Step-by-step explanation:

a: Looking at the points and the line, the graph is decreasing. I don't really know what your teacher exactly wants, but the answer could also be like "as the values of x increases, the values of y decreases."

b: On the graph, the time (number of hours) is shown in the x-axis. Given to calculate the remaining distance after 4 hours, we will substitute 4 into x.

y = -25x + 170

y = -25(4) + 170

y = -100 + 170

y = 70

There are 70 km remaining.

c: 170 is basically the y-intercept of the graph, where x is 0. When the time is 0, it means that the bicyclist didn't start moving. It is the exact starting point where the bicyclist will start cycling.

The total number of possibilities is 2475 possible 4-person committees with the same number of boys and girls in the Math-Fest Club.

This is a combination problem, and we can use the formula:
nCk = n! / (k! * (n - k)!)
Where n is the total number of students in the club (11 boys + 10 girls = 21), and k is the number of students we want to select (4).
nCk = 21C4

= 21! / (4! * (21 - 4)!)

= 21! / (4! * 17!)

= 5985
So there are 5985 ways to select 4 students from the club.
Now we need to determine how many of these committees have the same number of girls as boys.

We can do this by counting the number of ways to select 2 boys and 2 girls, and multiplying by the number of ways to arrange them in the committee.
To select 2 boys from the 11 available, we can use the formula:
nCk = n! / (k! * (n - k)!)
11C2 = 11! / (2! * (11 - 2)!) = 55
Similarly, we can select 2 girls from the 10 available:
10C2 = 10! / (2! * (10 - 2)!) = 45
So there are 55 * 45 = 2475 ways to select 2 boys and 2 girls for the committee.
Now we need to arrange them in the committee.

There are 4 positions, so we can use the formula:
nPk = n! / (n - k)!
4P4 = 4! / (4 - 4)! = 24
So there are 24 ways to arrange the 4 selected students in the committee.
Finally, we can multiply the number of ways to select the students by the number of ways to arrange them:
2475 x 24 = 59400

The equation of line is y = 30x + 75 , where the slope is m = 30 and the y intercept is 75

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( 1 , 105 )

Let the second point be Q ( 3 , 165 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 165 - 105 ) / ( 3 - 1 )

Slope m = ( 60 / 2 )

Slope m = 30

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 105 = 30 ( x - 1 )

On simplifying the equation , we get

y - 105 = 30x - 30

Adding 105 on both sides of the equation , we get

y = 30x + 75

Hence , the equation of line is y = 30x + 75

They have the same slope, the lines are parallel to one another.

If two non-vertical lines that are in the same plane has the same slope, then they are said to be parallel. Two parallel lines won't ever intersect.

The slopes of two perpendicular lines are negative reciprocals. The product of the slopes of two perpendicular lines is -1

We need to put these equations into y=mx+b format.

3x-5y=20

-5y=-3x+20. (take 5x from both sides)

y=3/5 x -4 ( divide both sides by -3)

The slope is 3/5

y=3/5x-1

The slope is 3/5

Answer:

2.44 miles

Step-by-step explanation:

Give the following :

Average miles to school = 12 miles per hour

Average Miles from school = 15 miles per hour

Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667

Recall:

Speed = distance / Time

Time = distance / speed

Let distance = d

For the scenario described :

d/12 + d/15 = 0.3667

(5d + 4d) / 60 = 0.3667

5d + 4d = 22

9d = 22

d = 22/9
