The value of function f(n) = f(n - 1) - 2, at n = 6 is f(6) = -4

In this question,

we have been given a function f(n) = f(n - 1) - 2

Also, we have been given the value of function f(n) for n = 1

i.e., f(1) = 6

We need to find the value of f(6).

For n = 2,

f(2) = f(2 - 1) - 2

f(2) = f(1) - 2

f(2) = 6 - 2

f(2) = 4

For n = 3,

f(3) = f(3 - 1) - 2

f(3) = f(2) - 2

f(3) = 4 - 2

f(3) = 2

For n = 4,

f(4) = f(4 - 1) - 2

f(4) = f(3) - 2

f(4) = 2 - 2

f(4) = 0

For n = 5,

f(5) = f(5 - 1) - 2

f(5) = f(4) - 2

f(5) = 0 - 2

f(5) = -2

For n = 6,

f(6) = f(6 - 1) - 2

f(6) = f(5) - 2

f(6) = -2 - 2

f(6) = -4

Therefore, the value of function f(n) = f(n - 1) - 2, at n = 6 is f(6) = -4

Answer:

x=19

Step-by-step explanation:

All of the angles add up to 180 degrees since it is a straight angle. So, the equation is:

3x+7+90+x+7=180

You combine like terms:

4x+104=180

Then you subtract on both sides:

4x=76

Then you divide by 4 on both sides:

The value of the angle 16°43'27"is approximately 16.724167 degrees.

A plane angle is measured in degrees, with the letter ° typically used to indicate that one full rotation is equal to 360 degrees.

To convert a degree from minutes and seconds to decimal we must know the relation between degree and minutes and seconds.

1 degree=60 minutes.

1 minute = 60 seconds.

The given angle is 16°43'27"

27 seconds = 27 ÷ 60 minutes = 0.45 minutes = 0.45 ÷ 60 degree =0.0075 degree

43 minutes= 43 ÷ 60 degree = 0.71666666..

Total angle in decimal = 16+0.71666666+0.0075 =16.7241666...

Therefore required angle ≈ 16.7241667 degrees.

Answer: X = 8.4 Y= 3.5

Step-by-step explanation:

For the function f(x) =(4 sin x)/(1+cosx) , then f'(x) = 4/(1+cosx) using quotient rule of differentiation and f'(2) = 2.00

Quotient rule for differentiation states that the differentiation the division of two functions u, v is given as

(u/v)' = (u' v  - u v')/v² , where '  represents first derivative  with respect to independent variable

Given f(x) = (4sinx)/(1+cosx)

let u =4 sin x , v = 1+cos x , u'=4cos x , v' = -sin x

Then f(x) =u / v

Using quotient rule of differentiation:

f'(x) = ( u' v -u v' )/v² = (4cosx(1+cosx) +4sin²x )/(1+cos x)²

f'(x) = = 4(cos x +cos² x +sin² x)/(1+ cos x)² = 4(cos x +1)/(1+ cos x)²  

f'(x) = 4/(1+ cos x)

To find value of f'(x) at x= 2

f'(5) = 4/(1+cos2) = 2.000609= 2.00(rounding off )

Therefore if f(x) = (4x² tan x)/sec x  then f'(x) = 4/(1+cos x) and f'(2) =2.00

The required solution to the equation 4x^3 + 16x^2 + 28x = 0 is 0, -2 +  i√3,  -2 -  i√3

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now the given equation is,

4x^3 + 16x^2 + 28x = 0

Taking x common we get,

x(4x^2 + 16x + 28) = 0

So, we get

x = 0

And 4x^2 + 16x + 28 = 0

or, x^2 + 4x + 7 = 0

Thus from the above equation is of the form

ax^2 + bx + c = 0

where, a = 1, b = 4 and c = 7

Therefore solution of the above equation is given as,

x = [-b ± √(b^2 - 4ac)] / 2a

Putting the values we get,

x = [-4 ± √(4^2 - 4*1*7)] / 2*1

so, x = [-4 ± √(16 - 28)] / 2

x = [-4 ± √(- 12)] / 2

x = [-4 ± 2√(- 3)] / 2

or, x = [-2 ± √(- 3)]

Since √-1 = i

∴ √(- 3) = i√3

Thus,

x = -2 ±  i√3

So, the required values of x are 0,  -2 +  i√3,  -2 -  i√3.

Thus, the required solution to the equation 4x^3 + 16x^2 + 28x = 0 is 0, -2 +  i√3,  -2 -  i√3.

[tex]\frac{5.025 \times 10^{10}}{1.5 \times 10^{8}} \\ \\ =\frac{5.025}{1.5}(100) \\ \\ =\boxed{335}[/tex]

Option A is correct, 5.025 x 10¹⁰ is 335 times larger than 1.5 x 10⁸.

To determine how many times larger one number is than another, we divide the larger number by the smaller number.

In this case, we want to find how many times larger 5.025 x 10¹⁰ is than 1.5 x 10⁸.

Dividing the larger number by the smaller number:

(5.025 x 10¹⁰) / (1.5 x 10⁸)

To simplify, we can divide the coefficients (5.025 / 1.5) and subtract the exponents (10¹⁰ - 10⁸):

(5.025 / 1.5) x 10¹⁰⁻⁸

Evaluating the division of the coefficients:

(3.35) x 10²

Therefore, 5.025 x 10¹⁰ is 3.35 x 10² times larger than 1.5 x 10⁸.

In decimal form, this can be expressed as:

3.35 × 10² = 335

Therefore, 5.025 x 10¹⁰ is 335 times larger than 1.5 x 10⁸.

Answer:

Slope of one of the dotted lines:

[tex]y=x[/tex] or [tex]y=x+5[/tex]

Slope of the line of reflection:

[tex]y=-x[/tex]

Step-by-step explanation:

When seeing the dotted lines, both of them have a rise & run of 1, indicating that y = x. However, one of the lines has a y-intercept of 5, making it y = x + 5. So, the slopes for the dotted lines are [tex]y=x[/tex] or [tex]y=x+5[/tex].

The line of reflection has a rise & run of -1, and goes through the origin, indicating that the equation is y = -x.

The equation of the line in slope intercept form is y = (-4/3)x + 7.

According to the slope intercept form, the equation of a line is given as-

y = mx + c

where m is the slope and c is the y intercept.

Here we are given that an equation passes through the point (9,-5) and has a slope of -4/3.

According to the point slope form, the equation of a line passing through (x1, y1) and slope m is given as-

(y - y1) = m(x - x1)

Here,

x1 = 9, y1 = -5 and m = -4/3

Thus,

(y + 5) = -4/3(x - 9)

3(y + 5) = -4(x - 9)

3y + 15 = -4x + 36

3y = -4x + 21

y = (-4/3)x + 21/3

y = (-4/3)x + 7

This is our equation in slope intercept format as m = -4/3 and c = 7

Thus, the equation of the line in slope intercept form is y = (-4/3)x + 7.
