2.) 2k

4.)24-13v

Step-by-step explanation:

The sum of the given series are:2(cos 2), cos 2 and 2cos 2.

Given series are:[infinity] (−1)n2n 42n(2n)! n = 0 [infinity] (−1)n2n 32n 1(2n)! n = 0 [infinity] (−1)n2n 4n(2n)! n = 0

To find the  Sum of the above series.

To find the sum of the given series, we have to use the Maclaurin's expansion of cosx which is given as:

cos x = 1 - x2/2! + x4/4! - x6/6! + x8/8! - x10/10! + ...

For x = 2, we have  cos 2 = 1 - 22/2! + 24/4! - 26/6! + 28/8! - ...

cos 2 = 1 - 2 + 4/24 - 16/720 + 256/40320 - ...

cos 2 = 1 - 2 + 1/6 - 1/45 + 1/1680 - ...

By simplifying the given series, we get:

Given series: [infinity] (−1)n2n 42n(2n)! n = 0

Sum = [42(cos 2)] / 2 = 2(cos 2)

Given series: [infinity] (−1)n2n 32n 1(2n)! n = 0

Sum = [32(cos 2)] / 2 = cos 2

Given series: [infinity] (−1)n2n 4n(2n)! n = 0

Sum = [4(cos 2)] / 2 = 2cos 2

Therefore, the sum of the given series are:2(cos 2), cos 2 and 2cos 2.

Answer:35

Step-by-step explanation:

The volume of a cylinder is calculated by multiplying the area of its base by its height. The formula for the volume of a cylinder is V = πr²h, where r is the radius of the base and h is the height.

The volume of a cone is calculated by multiplying the area of its base by its height and then dividing by 3. The formula for the volume of a cone is V = (1/3)πr²h, where r is the radius of the base and h is the height.

Since Sonequa’s two containers have equal radii and equal heights, it can be concluded that the volume of the cylinder is three times the volume of the cone. This means that if Sonequa fills the cone with water and pours it into the cylinder, she will need to repeat this process three times to fill the cylinder completely.

So, the claim that is most likely to be supported using the result of Sonequa’s investigation is: “The volume of a cylinder with the same radius and height as a cone is three times greater than the volume of the cone.”

Answer: √7 / 2 - 3/2

Step-by-step explanation:

√7-2x+5=8
=>  -2x + √7 = 3
=> x =  √7 / 2 - 3/2

the diameter of the circle is

D = 16 cm

so the radius is r = D/2 = 16/2 = 8cm

the area of the circle is,

put r = 8 and pi = 3.14

thus the area of the circle is 200.96 centimetres squared.

Points a b c d and e are collinear and in that the distance between points a and c is AC = 18.

If you can draw a straight line that passes through two or more points, then those points are collinear.

If points a, b, c, d, and e are collinear and in that order, then we can represent the distances between them as follows:

AB + BC + CD + DE = AE

AC + CD + CE = AE

Since we want to find AC, we can use the second equation and substitute the given values:

AC + CD + CE = AE

AC + CD + (x + 32) = (x + 50)

Now, we can use the fact that points a, b, c, d, and e are collinear to realize that CD = 0, since it is the distance between point c and itself. Therefore, we can simplify the equation:

AC + CD + (x + 32) = (x + 50)

AC + 0 + (x + 32) = (x + 50)

AC + x + 32 = x + 50

AC = 18

Therefore, the distance between points a and c is AC = 18.

The expression that is equivalent to the expression [(6c² + 3c)/(-4c + 2)] ÷ [(2c + 1)/(4c - 2)] is; -3c

Simplification of fractions is the process of reducing fractions that involves making the fraction as simple as feasible.

We achieve this by dividing the numerator and denominator by the greatest integer that divides perfectly into both numbers.

The given expression is;

\(\frac{[(6c^2 + 3c)(-4c + 2)] }{[(2c + 1)/(4c - 2)]}\)

On Simplifying the fraction equation by factorization we obtained ;

\(\frac{[3c(2c + 1)/(-2(2c - 1))]}{[(2c + 1)/(2(2c - 1)]}\)

\(\frac{[3c(2c + 1) }{(-2(2c - 1))] \times [(2(2c - 1)/(2c + 1)]}\)

Answer:110

Step-by-step exclamation:You have to add to get your answer.I'll show you how I got 110:

81+29=110

Your answer is:110

The numbers 1, 0.1, and 0.01 are related through the pattern of multiplying or dividing by 10.

The equation \(1 \times 10^{10} = 1 \times 10^1 = 10 \times 10^{0.1} = 0.1 \times 10^1\) demonstrates this pattern. By following this pattern, we can complete the equations \(x \times 10^x = 1 and x \times 10^x = 0.1.\)

The numbers 1, 0.1, and 0.01 are related through the pattern of multiplying or dividing by 10. Let's analyze the given example:

\(1 \times 10^10 = 1 × 10^1 = 10\\10 \times 10^1 = 10^2 = 100\\0.1 \times 10^1 = 10^0.1 = 1\)

We can observe that in each step, we either multiply or divide by 10.

To complete the equation \(x \times 10^x = 1\), we can substitute x = 0, which gives us:

\(0 \times 10^0\)

= 0 × 1

= 0

Therefore, x = 0 is a solution to the equation.

To complete the equation \(x \times 10^x = 0.1\), we can substitute x = -1, which gives us:

\((-1) \times 10^(-1) \\= -1 \times 0.1 \\= -0.1\)

Therefore, x = -1 is a solution to the equation.

In summary, the numbers 1, 0.1, and 0.01 are related through the pattern of multiplying or dividing by 10. By following this pattern, we can complete the equations \(x \times 10^x = 1\) and \(x \times 10^x = 0.1\) by substituting x = 0 and x = -1, respectively.

well, let's take a look at the tickmarks on the triangle, the tickmarks mean that AC = CB, both AC and CB stemming out of vertex C, and both twin sides will make twin angles at the "base" or namely ∡A = ∡B, that means that 34 = x - 5, let's also recall that the sum of all interior angles in a triangle is 180°, so

\(34=x-5\implies \boxed{39=x} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\measuredangle A}{34}~~ + ~~\stackrel{\measuredangle B}{34}~~ + ~~\stackrel{\measuredangle C}{4y}~~ = ~~180\implies 68+4y=180 \\\\\\ 4y=112\implies y=\cfrac{112}{4}\implies \boxed{y=28}\)

Answer:

y = 28

Step-by-step explanation:

The dashes on line segments AC and BC indicate that the line segments are equal in length.

Therefore, as the triangle has two sides of equal length, it is an isosceles triangle.

The base angles of an isosceles triangle are equal, therefore ∠A = ∠B.

Interior angles of a triangle sum to 180°.  

Therefore:

⇒ ∠A + ∠B + ∠C = 180°

⇒ 34° + 34° + 4y° = 180°

⇒ 68° + 4y° = 180°

⇒ 4y° = 112°

⇒ y = 112° ÷ 4°

⇒ y = 28

Step-by-step explanation:

Given equation of line:

\(\dfrac{x}{a}cos\theta+ \dfrac{y}{b}sin\theta =1\\OR\\\dfrac{x}{a}cos\theta+ \dfrac{y}{b}sin\theta-1=0\)

Given points are:

\((\sqrt{a^2-b^2},0), (-\sqrt{a^2-b^2},0)\)

Formula for distance between a point and a line is:

If the point is \((m, n)\) and equation of line is \(Ax+By+C = 0\)

Then, perpendicular distance between line and points is:

\(Distance = \dfrac{|Am+Bn+C|}{\sqrt{A^2+B^2}}\)

Here,

\(A = \dfrac{x}{a}cos\theta\\B = \dfrac{y}{b}sin\theta\\C = -1\)

For the first point:

\(m = \sqrt{a^2-b^2}, n = 0\)

By the above formula:

\(p\) and \(p'\) can be calculated as:

\(p\times p' =\\\Rightarrow \dfrac{|\dfrac{cos\theta}{a}\times \sqrt{a^2-b^2}+ 0 -1|}{\sqrt{\dfrac{cos^2\theta}{a^2}+\dfrac{sin^2\theta}{b^2}}}\times \dfrac{|-\dfrac{cos\theta}{a}\times \sqrt{a^2-b^2}+ 0 -1|}{\sqrt{\dfrac{cos^2\theta}{a^2}+\dfrac{sin^2\theta}{b^2}}}\\\Rightarrow \dfrac{1-(\sqrt{a^2-b^2}\times \frac{cos\theta}{a})^2}{\dfrac{cos^2\theta}{a^2}+\dfrac{sin^2\theta}{b^2}}}\)

Formula used:

\((x+y)(x-y) = x^2 - y^2\)

\(\Rightarrow \dfrac{\dfrac{a^2-a^2cos^2\theta+b^2cos^2\theta}{a^2}}{\dfrac{b^2cos^2\theta+a^2sin^2\theta}{a^2b^2}}\\\Rightarrow b^2(\dfrac{a^2sin^2\theta+b^2cos^2\theta}{a^2sin^2\theta+b^2cos^2\theta})\\\Rightarrow b^2\)

(Using the identity:

\(sin^2\theta +cos^2\theta = 1\))

The diagram with blue dots will be the adjusted plot points to get the best fit for the scatter diagram. We will: option c) decree the y-intercept and increase the slope to get this.

The best-fitted line is that particular line that passes through a maximum of the point and is very close to them.

Here we see that most of the scatter points line below the fitted line. Hence we need to lower these by decreasing the y-intercept.

After lowering this, we will notice that the lines are flatter than most of the points here. Hence to make the line a better fit, we will increase the slope of the line.
