Here we have given that the function is [tex]\sum\frac{(-1)^n\pi^{2n}}{4^{2n}(2n)!}[/tex]

And we need to find the sum of series by using the Maclaurin series as

Now, the sum of series is calculated as,

=>f(n) =  [tex]\sum\frac{(-1)^n\pi^{2n}}{4^{2n}(2n)!}[/tex]

When we put the value on n = 0, then we get,

=> f(0) = [1 x 3.14]/1] =  3.14

Now, we have to put the value of the function, the value of x as 1,

Then we get,

=> f(1) = [-1 x 9.8596] / [16 x 2]

=> f(1) = -0.308

And then we have to put the value of function for the value of x as 2,

Then we get,

=> f(2) = [1 x 30.959] / [64 x 24]

The value of k where the roots of the quadratic equation are real and equal is k = 9.

Option B is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

3x + 6 = 9 is an equation.

We have,

3x² + 2kx + 27 = 0

This is in the form of ax² + bx + c.

a = 3

b = 2k

c = 27

Now,

The roots are real and equal.

D = 0

D = b² - 4ac

Now,

b² - 4ac = 0

(2k)² - 4 x 3 x 27 = 0

Step-by-step explanation:

You want the domain of the rational function f(x) = (x +4)/(3x -5).

Domain

The domain is the set of input values for which the function is defined. A rational function is undefined when its denominator is zero. f(x) is undefined when ...

  3x -5 = 0

When $36$ consecutive integers are added, the result is $-18$. What is the greatest product that can be obtained by multiplying two of these $36$ integers?

Answers

The greatest product that can be obtained by multiplying two of these 36 integers is; 306

How to solve mathematical sequence?

We are told that when 36 consecutive integers are added, the product is -18.

Now, the sequence for these integers would be;

x, (x + 1), (x + 2), (x + 3),......(x + 35)

Now, since the addition of these integers gives a negative number, then it suggests to us that the sequence starts with a negative integer and then ends with a positive integer.

Thus, we have;

x + (x + 1) + (x + 2) +(x + 3) + (x + 35) = -18

The formula for sum of an arithmetic sequence is;

Sₙ = (ⁿ/₂)(2a + (n - 1)d)

where a is first term and d is common difference

Thus;

-18 = (36/2)(2x + (36 - 1)1)

-18 = 18(2x + 35)

-18/18 = 2x + 35

2x + 35 = -1

x = -34/2

x = -17

Thus;

The first term = -17

Last term = -17 + 35 = 18

Thus, the greatest product that can be obtained  = 18 * 17 = 306

How do you determine the nature of the roots of a quadratic equation example?

Answers

The nature of the roots of a quadratic equation is described by the discriminant calculated by seeing the equation and comparing it with the standard equation which is given by -

[tex]ax^{2} + bx+c[/tex] , where a , b , c are real numbers .

The root of the equation is given by -

x= (-b )± [tex]\frac{\sqrt{b^{2} - 4ac}}{2a}[/tex]

Here, the term (b^2 - 4ac) is called the discriminant of the quadratic equation .

This discriminant is the defining factor of the nature of the roots.

Now, here arise three cases-

(i) If (b^2 - 4ac) > 0, the roots are real and distinct .

(ii) If (b^2 - 4ac) = 0 , the roots are real and equal.

(iii) If (b^2 - 4ac) < 0 , the roots are not real and they are imaginary i.e. they are complex in nature and of the form a+ib.

Hence, it is the discriminant which determines the nature of roots.

Use the diagram below to find the following measures. GN is the angle bisector of ∠MGO.

Answers

Answer:

∠MGN = 24°

∠NGO = 24°

Step-by-step explanation:

What is an angle bisector?

An angle bisector is a line, segment, or ray that splits an angle in halfEach halve of the angle is equal to each other

Thus, ∠MGN ≅ ∠NGO.

To solve for ∠MGN and ∠NGO, we need to:

Create an equation about their relationshipSolve for "x"Substitute "x" back into the equations to find the angle measures

1. Create an equation about their relationship:

If ∠MGN ≅ ∠NGO, then...

[tex]5x-6 = 11x -42[/tex]

2. Solve for "x":

[tex]5x - 6 = 11x -42[/tex]

[tex]42 - 6 = 11x - 5x[/tex]

[tex]36 = 6x[/tex]

[tex]6 = x[/tex]

3. Substitute "x" back into the equations to find the angle measures:

[tex]< MGN = 5x - 6[/tex]

[tex]< MGN = 5(6) - 6[/tex]

[tex]< MGN = 30 - 6[/tex]

[tex]< MGN = 24[/tex]

❗❗❗At this point, you could write that ∠MGN and ∠NGO = 24°, as they are congruent, but you should still substitute "x" into  ∠NGO to make sure "x" is correct.❗❗❗

[tex]< NGO = 11x - 42[/tex]

[tex]< NGO = 11(6) - 42[/tex]

[tex]< NGO = 66 - 42[/tex]

[tex]< NGO = 24[/tex]

∴ ∠MGN = 24°

∴ ∠NGO = 24°

solving systems by substitution

Answers

Answer: x=-3, y=2

Step-by-step explanation: to solve using substitution, we need either x or y by itself in one equation. let's use x from the 2nd equation since it doesn't have a constant.

so the first equation stays the same at 2x+3y=0

for the second equation, rearrange to solve for x by moving the 2y to the right -> x=2y-1

then, we can plug in this x value to x in the first equation to get,

2(2y-1)+3y=0

then solve for y,

4y-2+3y=0

4y-3y=2

y=2

then to solve for x, plug in y in either of the initial equations. lets choose the second one.

so you'd have,
