The inverse of f(x)=−8x+9 is y = (-x + 9)/8.

The inverse of a function is found by switching the x and y variables and solving for y. This is done to find the function that will undo the original function.

To find the inverse of f(x)=−8x+9, we will follow these steps:

1. Switch the x and y variables: x = -8y + 9
2. Solve for y by isolating the y variable on one side of the equation:
x - 9 = -8y
(x - 9)/-8 = y
3. Simplify the equation by dividing the numerator and denominator by -1:
y = (-x + 9)/8

Therefore, the inverse of f(x)=−8x+9 is y = (-x + 9)/8.

Note that we do not need to use parentheses around the denominator since it is a single term. We also do not need to use the term "inverse" in our answer since we are simply finding the inverse of the function. The terms "denominator" and "parentheses" are also not needed in our answer since they do not apply to this specific problem.

The equation for the line that passes through the point (-1,4) and that is parallel to the line with the equation y=2 is y=4.

To find the equation for the line that passes through the point (-1,4) and that is parallel to the line with the equation y=2, we need to use the concept of slope. The slope of a line is the ratio of the vertical change to the horizontal change between any two points on the line.

The equation y=2 is a horizontal line, which means that its slope is 0. Since the line we are looking for is parallel to this line, its slope will also be 0.

Now that we know the slope, we can use the point-slope form of an equation to find the equation of the line. The point-slope form of an equation is [tex]y-y1=m(x-x1)[/tex], where m is the slope and [tex](x1,y1)[/tex] is a point on the line.

Plugging in the values we know, we get:

[tex]y-4=0(x-(-1))[/tex]

Simplifying the equation, we get:

[tex]y-4=0[/tex]

Adding 4 to both sides of the equation, we get:

[tex]y=4[/tex]

So the equation for the line that passes through the point (-1,4) and that is parallel to the line with the equation y=2 is [tex]y=4[/tex].

The equations that represent functions are:

  1) 2x + 3y = 10

  2) 3y = 18

Functions are relations which give a particular output for each input.  The characteristic that every input is associated with exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs. Specific input is supplied to a function in order to produce a specific result. To determine if a curve is a function or not, apply the vertical line test. Any curve that intersects a vertical line at more than one point is not a function.

Let us look into each equation.

1)  2x + 3y = 10

Here for each input of x, we get only one output y.

So this is a function.

2)  4x = 16

 This is not a function because there can be multiple values of y for a single value of x.

3) 2x − 3 = 14

 This is also not a function because there can be multiple values of y for a single value of x.

4)  3y = 18

 This is a function because there is only one value of y for exactly one value of x. Also, considering the vertical line test, the curve is a straight horizontal line which intersects with a given vertical line only once. So it is a function.

5)14.6 = 2x

  This is also not a function because there can be multiple values of y for a single value of x.

Therefore the equations that represent functions are:

Therefore , the solution of the given problem of function comes out to be Nolan dropped the ball from a height of 12 units at the beginning.

The study of mathematics includes numbers, symbols, and their parts, as well as anatomy, building, and both actual and hypothetical geographic locations. The relationships between different components, each of which has a corresponding result, are described by a function. A function is made up of a variable of distinct components that, when put together, produce specific results for each input.

Here,

Assume that h represents the original height at which Nolan threw the ball. The object bounces once and rises to a height of 4, so after the bounce it has a height of h + 4.

=> h = k f(1) (1)

where k is a constant that denotes how much energy the object retains after each bounce.

=> h = k(4) (4)

The knowledge that the ball returns to a height of 4 on the first bounce must be used to determine the value of k:

=> 4 = k f(1) (1)

=> 4 = k (4/3)

=> k = 3

When we put this number of k back into the equation as a replacement for h, we get:

=> h = k(4) = 3(4) = 12

The intersection point of ℓ and Q is (1, 1, 2.5) is not in any of the option.

To find the intersection point of ℓ and Q, we need to find a point that lies on both the line and the plane. We can do this by finding the equation of the line and the equation of the plane, and then solving for the point where they intersect.

First, let's find the equation of the line ℓ. We can use the formula for a line passing through two points:

(x - x1) / (x2 - x1) = (y - y1) / (y2 - y1) = (z - z1) / (z2 - z1)

Plugging in the points (1, 1, 1) and (2, 0, 1), we get:

(x - 1) / (2 - 1) = (y - 1) / (0 - 1) = (z - 1) / (1 - 1)

Simplifying, we get:

x - 1 = -y + 1 = 0

So the equation of the line is x + y = 2.

Next, let's find the equation of the plane Q. We can use the formula for a plane passing through three points:

| x - x1  y - y1  z - z1 |
| x2 - x1  y2 - y1  z2 - z1 | = 0
| x3 - x1  y3 - y1  z3 - z1 |

Plugging in the points (0, 0, 0), (1, 2, 2), and (1, 0, 1), we get:

| x   y   z |
| 1   2   2 | = 0
| 1   0   1 |

Expanding the determinant, we get:

x(2 - 0) - y(2 - 1) + z(0 - 2) = 0

Simplifying, we get:

2x - y - 2z = 0

So the equation of the plane is 2x - y - 2z = 0.

Now we can solve for the intersection point of the line and the plane by substituting the equation of the line into the equation of the plane:

2(x + y) - y - 2z = 0

2x + 2y - y - 2z = 0

2x + y - 2z = 0

Since x + y = 2, we can substitute 2 for x + y:

2(2) + y - 2z = 0

4 + y - 2z = 0

y - 2z = -4

Now we can solve for y in terms of z:

y = 2z - 4

And substitute this back into the equation of the line:

x + (2z - 4) = 2

x = 2 - 2z + 4

x = 6 - 2z

Now we have two equations with two unknowns:

y = 2z - 4
x = 6 - 2z

We can solve for z by setting the two equations equal to each other:

2z - 4 = 6 - 2z

4z = 10

z = 2.5

And then solve for x and y:

y = 2(2.5) - 4 = 1
x = 6 - 2(2.5) = 1

So the intersection point of ℓ and Q is (1, 1, 2.5).

The common tangent of the compound curve is parallel to its long chord. This means that the angle between the common tangent and the long chord is 0°. The long chord makes an angle of 18° with the shorter tangent and 12° with the longer tangent. We can use the law of sines to determine the length of the common tangent.

Let's call the length of the common tangent x, the length of the long chord L, the angle between the common tangent and the long chord θ, the angle between the long chord and the shorter tangent α, and the angle between the long chord and the longer tangent β.

Using the law of sines, we have:

x/sin(θ) = L/sin(α+β)

Substituting the given values, we have:

x/sin(0°) = 546/sin(18°+12°)

Simplifying the equation, we get:

x = 546*sin(0°)/sin(30°)

Since sin(0°) = 0 and sin(30°) = 0.5, we have:

When the process of rolling a fair 20-sided die 60 times and computing the value of chi-square using expected counts of 3 for each face is repeated many times, the distribution of the values of chi-square should be approximately normal. This is because the chi-square distribution is a special case of the gamma distribution, and as the degrees of freedom increase, the chi-square distribution approaches a normal distribution. In this case, the degrees of freedom are 19 (20-1), which is a relatively large number, so the distribution should be approximately normal.

The plane will end up flying 1.7 degrees off course.
The plane's speed relative to the ground will be 729.1 km/hr.

To determine the plane's speed and direction relative to the ground, we need to use vector addition to combine the velocity of the plane and the velocity of the wind.

First, let's find the components of the wind velocity. Since the wind is blowing from the southeast, its x-component is -30cos(45) = -21.2 km/hr and its y-component is -30sin(45) = -21.2 km/hr.

Next, let's find the components of the plane's velocity. Since the plane is heading north, its x-component is 0 km/hr and its y-component is 750 km/hr.

Now, we can add the components of the plane's velocity and the wind's velocity to find the plane's velocity relative to the ground:

x-component: 0 + (-21.2) = -21.2 km/hr

y-component: 750 + (-21.2) = 728.8 km/hr

Finally, we can use the Pythagorean theorem to find the magnitude of the plane's velocity relative to the ground:

speed = sqrt((-21.2)^2 + (728.8)^2) = 729.1 km/hr

And we can use the inverse tangent function to find the direction of the plane's velocity relative to the ground:

direction = tan^(-1)(-21.2/728.8) = -1.7 degrees

So, the plane will end up flying 1.7 degrees west of north, and its speed relative to the ground will be 729.1 km/hr.
