The linearization of the given function near x = -0.9 is approximated by the linear equation -x - 7, with the center of the linearization at x = -1. This equation is obtained by evaluating the function and its derivative at x = -1, then using them to approximate the value of the function at x = -0.9.

The linearization of the given function f(x) = 3x^2 + 2x - 3 near the point x = -0.9 is a linear equation that approximates the value of the function at the point. To obtain the linearization, we must first choose a suitable integer near -0.9 at which the function and its derivative are easy to evaluate. In this case, we choose x = -1 as the center of the linearization. To obtain the linearization equation, we evaluate the function and its derivative at x = -1, then use them to approximate the value of the function at x = -0.9. This results in the linear equation -x - 7. This equation allows us to approximate the value of the function at x = -0.9 without having to calculate the value of the function directly.

f(-1) = 6

f'(-1) = -1

Linearization: f(x) ≈ f(-1) + f'(-1)(x + 1)

= 6 - 1(x + 1)

= -x - 7

The required area of the regular 12-gon is obtained as 3 square units.

A regular polygon can be defined as a polygon having all of its sides and angles equal to one another. The expression for each angle of a regular polygon is 180(n - 2)/n.

The angle between two sides of regular 12-gon is given as below,

180(12 - 2)/12 = 150°.

Now, the area of regular 12-gon is equivalent to the area of sum of 12 triangles.

The angle for the triangle will be 150/2 = 75°.

The diagram for such a triangle is given as below,

Now, OC = 1 × Sin B

⇒ OC = Sin 75°

And, BC =  1 × Cos B

⇒  BC = Cos 75°

Then, AB = 2BC = 2Cos 75°

Area of the triangle is given as,

1/2 × base × height

⇒ 1/2 × Sin 75° × 2Cos 75°

⇒ 0.25

Now, the area of the regular 12-gon inscribed in a unit circle is given as,

12 × 0.25 = 3 square units.

Hence, the area of a regular 12-gon inscribed in a unit circle is 3 square units.

As per the polar coordinates, the limits of the integration is written as ∬Df(rcos⁡(θ),rsin⁡(θ))rdrdθ.

What is meant by polar coordinates?

In math, polar coordinates refer a pair of coordinates locating the position of a point in a plane, the first being the length of the straight line ( r ) connecting the point to the origin, and the second the angle ( θ ) made by this line with a fixed line.

Here we have  the limits of integration and evaluate the integral to find the volume. for the polar coordinates.

Here we have the polar representation of a point P is the ordered pair (r,θ) where r is the distance from the origin to P and θ is the angle the ray through the origin and P makes with the positive x-axis.

Then the polar coordinates r and θ of a point (x,y) in rectangular coordinates satisfy

=> r=x² + x²      and      tan⁡(θ)=yx;

Here the rectangular coordinates x and y of a point (r,θ) in polar coordinates satisfy and x=rcos⁡(θ) and y=rsin⁡(θ).

Then the area element dA in polar coordinates is determined by the area of a slice of an annulus and is given by dA=rdrdθ.

Here we have to convert the double integral ∬Df(x,y)dA to an iterated integral in polar coordinates,

Now, we have to substitute rcos⁡(θ) for ,x, rsin⁡(θ) for ,y, and rdrdθ for dA to obtain the iterated integral

=> ∬Df(rcos⁡(θ),rsin⁡(θ))rdrdθ.

115°=115°

Step-by-step explanation:

Because the angles in a triangle add up to 180°, 115°+(x+17)°+(7x-16)°=180°

Now we can solve algebraically.

115°+(x+17)°+(7x-16)°=180°

115+x+17+7x-16=180

Rearrange:

115+17-16+7x+x=180

Solve:

115+1+8x=180

116+8x=180

8x=180-116

8x=64

x=8

Now we can fill x in to find the measure of the angles.

The function itself is the derivative of a function's integral. But only in the case of indefinite integrals is this always the case.

The value of a new vehicle after the first 12 months of ownership is given by the equation:

value after 12 months = value at time of purchase × (1 - depreciation rate)

In this case, the value of the vehicle at the time of purchase is 63,580, and the depreciation rate is 20%. Plugging these values into the equation gives us:

value after 12 months = 63,580 × (1 - 0.20) = 50,864

The value of the vehicle after five years is given by the equation:

value after 5 years = value after 12 months × [tex](1 - depreciation rate)^n[/tex]

The simplified expression of [(b - 3)/(b² + 2b)] + [b/(4b + 8)] is (b² - 12 + 4b)/[(4b)(b + 2)]

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

[(b-3)/(b^2+2b)]+[b/(4b+8)]

Rewrite the exponents

[(b - 3)/(b² + 2b)] + [b/(4b + 8)]

So, we have

(b - 3)/(b² + 2b) + b/(4b + 8)

Factor out b and 4

(b - 3)/b(b + 2) + b/4(b + 2)

Factor out 1/(b + 2)

1/(b + 2) * ((b - 3)/b + b/4)

So, we have

1/(b + 2) * (4(b - 3) + b²)/(4b)

This gives

1/(b + 2) * (4b - 12 + b²)/(4b)

Rewrite as

1/(b + 2) * (b² - 12 + 4b)/(4b)

For 30N force which is acting at 45 angles with the x−axis, its x−component will pass through the origin, hence its horizontal component will also not cause any torque about O

Hence, torque because of 20N force which is acting in a tangential direction :

The recurrence relation an = an-1 + an-3 counts the number of ways to climb n stairs if you can take either 1 stair or 3 stairs at a time.

What is a recurrence relation?

A recurrence relation is an equation that defines a sequence of values in terms of the preceding terms of the sequence. It is a mathematical tool used to define a sequence of numbers, functions, or other mathematical objects in a recursive manner.

To find a recurrence relation that counts the number of ways to climb n stairs if you can take either 1 star or 3 stairs at a time, we can use the following steps:

Identify the base cases. In this case, the base cases are the number of ways to climb 0 stairs (an = 1) and the number of ways to climb 1 stair (an = 1).

Determine the recurrence relation. For n > 1, the number of ways to climb n stairs is equal to the number of ways to climb n-1 stairs (taking 1 stair at a time) plus the number of ways to climb n-3 stairs (taking 3 stairs at a time). Therefore, the recurrence relation is:

an = an-1 + an-3

Use the base cases and the recurrence relation to determine the values of an for the desired range of n.

For example, to determine the values of an for n = 0, 1, 2, 3, 4, and 5, we can use the following table:

n | an

0 | 1

1 | 1

2 | an-1 + an-3 = 1 + 1 = 2

3 | an-1 + an-3 = 2 + 1 = 3

4 | an-1 + an-3 = 3 + 2 = 5

5 | an-1 + an-3 = 5 + 3 = 8

Hence, the recurrence relation an = an-1 + an-3 counts the number of ways to climb n stairs if you can take either 1 stair or 3 stairs at a time.
