The bearing of the airport from the plane is 245°

The bearing of a point from a location is given by the angle in degrees of rotation from the Northern direction of the location to the direction of the location of the point

The given bearing of the plane from the airport = 65°

Therefore, the direction of the plane from the Northern direction of the airport = 65°

From the Northern direction of the plane, the bearing of the airport = 245°

Hence, the bearing of the airport from the plane is 245°

The function is invertible and the inverse of the function is y = -3 + √[ (x + 4)/-2]

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

y=-2(x+3)^2-4

Swap the variables x and y

So, we have

x = -2(y + 3)^2 - 4

Add 4 to both sides

-2(y + 3)^2 = x + 4

Divide both sides by -2

(y + 3)^2 = (x + 4)/-2

Take the square root and subtract 3 from both sides

y = -3 + √[ (x + 4)/-2]

This represents the inverse of the function

9 divided by 11.91 rounded to the nearest hundredth is: 0.76

To show that two numbers are divided, we can add a division sign '÷' between them. So, for example, if we have to show 36 divided by 6, we can write it as 36 ÷ 6. We can also show it in a fraction form as 36/6.

We want to find 9 divided by 11.91 . Thus, this can be expressed as:

9/11.91

The numeric value of f(x) at x = π/5 is given as follows:

f(π/5) = - 2π/5 - 2

We are given the second derivative of the function, as follows:

f''(x) = -25sin(5x).

As we have the second derivative of the function, the function itself is obtaining integrating the second derivative twice.

Using integral by substitution, the first derivative is given as follows:

f'(x) = 5cos(5x) + K1

In which K1 is the constant.

When x = 0, f'(0) = 3, hence the value of K1 is obtained as follows:

3 = 5 + K1

K1 = -2.

Hence:

f'(x) = 5cos(5x) - 2.

Integrating again, the function is given as follows:

f(x) = 5sin(5x) - 2x + K2.

When x = 0, y = -2, hence the constant K2 is obtained as follows:

K2 = -2.

Thus the function is:

f(x) = 5sin(5x) - 2x - 2.

The numeric value of the function at x = π/5 is obtained as follows:

f(π/5) = 5sin(5(π/5)) - 2(π/5) - 2.

f(π/5) = 5sin(π) - 2π/5 - 2

f(π/5) = - 2π/5 - 2 -> as sin(π) = 0.

The steps to graph the absolute value functions are given below.

We have,

Absolute value functions of form f(x) = |ax + b| have a characteristic shape, which depends on the values of a and b.

Here are some general guidelines for graphing these functions:

Find the y-intercept:

To find the y-intercept of the graph, set x=0 and solve for y.

This gives f(0) = |b|, so the y-intercept is at the point (0,|b|).

Find the x-intercept(s):

To find the x-intercepts of the graph, set y = 0 and solve for x.

If b > 0, there are two x-intercepts: x = -b/a and x = b/a.

If b = 0, there is one x-intercept at x=0.

If b < 0, there are no x-intercepts.

Determine the direction of the graph:

If a > 0, the graph opens upwards, like a "V".

If a < 0, the graph opens downwards, like an upside-down "V".

Determine the vertex:

The vertex is the point where the graph changes direction.

If a > 0, the vertex is at (-b/a, 0).

If a < 0, the vertex is at (b/a, 0).

Sketch the graph:

Use the information above to sketch the graph of the absolute value function.

Plot the y-intercept, the x-intercept(s), and the vertex, and then draw a smooth curve connecting these points.

Thus,

The graph of the absolute value functions is given above.

The circumference of the circle is 50.272in and the area is 3.142 x 8² = 200.96in².

The formula for circumference of a circle is given as:

  C = 2[tex]\pi[/tex]r

where r is the radius

and [tex]\pi[/tex] is 3.142

Area of a circle is given as:

   A = [tex]\pi r^{2}[/tex]

From the diagram,

diameter (d) given is 16in i.e:

d = 16in

but

r = d/2 = 16/2 = 8in

Now solve the C and A using the formula above:

C = 2 x 3.142 x 8 = 50.272in (approx.)

A = 3.142 x 8² = 200.96in² (approx.)

Briefly, a circle is a two-dimensional geometric shape consisting of all points in a plane that are a fixed distance, called the radius, from a given point called the center.

Any quarter with sales level less than or equal to 7.908 million dollars would be considered a "failure" by this company.

To determine this sales level, we need to find the 20th percentile of the normal distribution with mean 9 million dollars and standard deviation 1.3 million dollars.

By using a standard normal distribution table we can find that the z-score corresponding to the 20th percentile is approximately -0.84.

The sales level that is the cutoff between quarters that are considered "failures" will be:

-0.84 = (x - 9)/1.3

- 0.84 * 1.3 = x - 9

- 1.092 = x - 9

Answer:

x ≈ 11.3

Step-by-step explanation:

using the cosine ratio in the right triangle

cos61° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{DE}{DF}[/tex] = [tex]\frac{5.5}{x}[/tex] ( multiply both sides by x )

x × cos61° = 5.5 ( divide both sides by cos61° )

x = [tex]\frac{5.5}{cos61}[/tex] ≈ 11.3 ( to the nearest tenth )

The value of x in the triangular pyramid is 8 units.

The volume of the pyramid is given as 240 units cube. Therefore, let's find the value of x in the pyramid.

volume of the pyramid = 1 / 3 ×base area × height

base area = 1 / 2 bh

base area = 1 / 2 × 12 × x

base area = 6x

Therefore,

volume of the pyramid =  1 / 3 × 6x × 15
