Answer:

See the explanation

Step-by-step explanation:

We know that

f(x) = 2x⁶ + 3x⁴ - 4x³ + (1/x) - sin2x

Lets calculate the derivatives:

f'(x) = 6(2x⁵) + 4(3x³) - 3(4x²) -( 1/x²) - 2(cos2x)

f'(x) = 12x⁵ + 12x³ - 12x² - (1/x²) - 2cos2x

Similarly:

f''(x) = 60x⁴ + 36x² - 24x + (2/x³) + 4sin2x

f'''(x) = 240x³ + 72x - 24 - (6/x⁴) + 8cos2x

Rearrange:

f'''(x) - 240x³ +72x - (6/x⁴) + 8cos2x - 24

f''''(x) = 720x² + 72 + (24/x⁵) - 16sin2x

Rearrange:

f''''(x) = 720x² + (24/x⁵) - 16sin2x +72

Step-by-step explanation:

The length of the arc in its simplest form will be 138.16 units.

Let r is the radius of the sector and θ be the angle subtended by the sector at the center. Then the arc length of the sector of the circle will be

Arc = (θ/2π) 2πr

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

In a circle with a radius of 22, an angle measuring 2π radians intercepts an arc.

Then the length of the arc in the simplest form will be given as,

Arc = (2π/2π) 2π (22)

Arc = 44 x 3.14

Arc = 138.16 units

The length of the arc in its simplest form will be 138.16 units.

suplementary means adds to 180

a+b=180

a=83

83+b=180

minus 83 both sidse

b=97

answer is 97 degrees

Answer:

97°

Step-by-step explanation:

Supplementary angles are a pair of angles whose sum is 180°.

If one angle of a pair of supplementary angles is given, it is easy to find the other angle.

It can be found out by subtracting the given angle from 180.

So here in this case, ∠A + ∠B = 180° where ∠A = 83°

83 + ∠B = 180

∠B = 180 - 83

∠B = 97°

So the m∠B = 97°

Step-by-step explanation:

1. it is an equilateral triangle.

let  base=2x

let h be the height from centre.

h/8=sin 30=1/2

h=1/2×8=4

so total height=8+4=12

again  x/8=cos 60

x=(√3/2)×8=4√3

Base=2x=2×4√3=8√3

area of triangle=1/2×8√3×12=48√3 sq. units.

Answer:

8.7 plus b equals 54.6

Step-by-step explanation:

4(8.7) + b = 54.6.

b = 19.8 cm.

The sum of the sides = the perimeter = 3a + a + b = 54.6.  

Now a = 8.7, so:

3(8.7) + 8.7 + b = 54.6

4(8.7) + b = 54.6.

b = 54.6 - 4(8.7)

b = 19.8.

Answer: D.) 34.8 + b = 54.6

Step-by-step explanation:

Using the Slope Equation:

Pick two points on the line and determine their coordinates.

Determine the difference in y-coordinates of these two points (rise).

Determine the difference in x-coordinates for these two points (run).

Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

How do you calculate rise over run?

Multiply the slope by the run to calculate the rise between subsequent points. In the example, if you wanted to know the rise given a run of 10, multiply 10 times 0.6 to calculate a rise of 6. Divide the rise by the slope to calculate the run.

What does a slope of mean?

The slope of a line is the steepness of the line. There are many ways to think about slope. Slope is the rise over the run, the change in 'y' over the change in 'x', or the gradient of a line.

How do I find slope?!

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

Answer:

A. 0

Step-by-step explanation:

In a function, all x-coordinates must be different.

The given function already shows 1, 2, 5, and 8 as x-coordinates, so you must choose a number other than those.

Answer: 0

The correct option will be Option A : the value of k will be 0.

The function is a relation between two sets where one set is called the domain and another set is the codomain which is one one or many one relations.

If the x or input values are different then the relation will become a function.

So we can say if the x values are repeated and their corresponding y or output values are the same, then also the relation becomes a function.

If the x values are repeated and their corresponding y or output values are different, then the relation will not become a function.

Given the ordered pairs are {(1,3), (2, 9), (k, 12), (5,9), (8,0)

As we know the x value is repeated and the y value is different then the relation will not be a function.

So here in the given ordered pair, there is no any second 12. So k value should not be equal to 1,2,5,8 otherwise it will not be a function.

By checking all the options

0 is not present in x value of the given ordered pair.

Therefore the correct option will be Option A : the value of k will be 0.

Step-by-step explanation: - (-3) should be a positive 3 when simplified. Whenever there is two negative sign in front of a number it is going to be positive.

The solution to the expression is A = 6

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the expression , we get

A = -2 + 5 - ( -3 )

On simplifying , we get

Step 1 :

A = -2 + 5 + 3

The - ( -3 ) becomes positive value and Amar made a mistake in Step 1

So , the value of A is

Step 2 :

A = -2 + 8

On simplifying the equation , we get

Step 3 :

A = 6

Therefore , the value of A is 6

Hence , the expression is A = 6
