To find the interval of convergence and radius of convergence for the power series sigma^[infinity]_n=1 ((−1)^n x^n/n), we will use the ratio test.

Ratio test: Let the series sigma^[infinity]_n=1 a_n be a power series centered at x = c. Then, the radius of convergence is given by R = lim_n→∞ |a_n/a_n+1|, if the limit exists.

First, we apply the ratio test:

|(-1)^(n+1) * x^(n+1)/(n+1)| / |(-1)^n * x^n/n|

= |x/(n+1)|

Taking the limit as n → ∞, we get

lim_n→∞ |x/(n+1)| = 0

Therefore, the radius of convergence is R = ∞.

Next, we need to find the interval of convergence. Since R = ∞, the series converges for all x. Thus, the interval of convergence is

I = (-∞, ∞).

Therefore,

I = (-∞, ∞)
R = ∞
To find the interval of convergence (I) and radius of convergence (R) for the given power series, we can use the Ratio Test. The power series is:

Σ(−1)^n * (x^n / n) from n=1 to infinity.

Applying the Ratio Test:

lim (n→∞) |(a_(n+1)) / a_n| = lim (n→∞) |((-1)^(n+1) * x^(n+1) / (n+1)) / ((-1)^n * x^n / n)|

After simplification:

lim (n→∞) |n * x / (n+1)|

Since the (-1) terms cancel out, we are left with:

lim (n→∞) |n / (n+1) * x|

As n approaches infinity, the limit becomes 1, and thus:

|x| < 1

This gives us the interval of convergence (I):

I = (-1, 1)

For the radius of convergence (R), since |x| < 1:

R = 1

The absolute maximum and absolute minimum values of f on the given interval f(t) = 2 cos (t) + sin (2t), [0, π/2] is 3√3/2 and 0 respectively.

Given :Y = 2cost + sin2t

differentiate wrt t

dy/dt = -2sint +2cos2t = 0

sint = cos2t = 1 - 2sin²t

2sin²t + sint -1 = 0

2sin²t + 2sint - sint - 1 = 0

2sint (sint +1 ) -(sint+1) = 0

sint = 1/2 and -1

but  t € [ 0, π/2 ] so, sint = 1/2 = sinπ/6

t = π/6

again, differentiate wrt t

d²y/dt² = -2cost -4sin2t

put t = π/6

d²y/dt² = -2× √3/2 - 4×√3/2 < 0

hence, d²y/dt² < 0

So, at t = π/6 function gain, Maxima

now,

f(0) = 2cos(0) +sin2(0) = 2

f(π/6) = 2cos(π/6) + sin2(π/6) = 3√3/2

f(π/2) = 2cos(0) + sin2(π/2) = 0

True.All regular polygons can be inscribed in a circle, as their vertices lie on the circle's circumference.

A regular polygon is a polygon that has all sides and angles equal. When a regular polygon is inscribed in a circle, it means that all of its vertices lie on the circumference of the circle.

To visualize this, imagine drawing a regular polygon, such as a triangle, square, pentagon, or hexagon, inside a circle. Each vertex of the polygon touches the circumference of the circle. This property holds true for any regular polygon, regardless of the number of sides it has.

One way to understand why this is true is by considering the angles formed at the center of the circle. The angles between the radii (lines connecting the center of the circle to the vertices of the polygon) are all equal in a regular polygon. Since the sum of the angles around a point is always 360 degrees, the angles at the center of the circle must also add up to 360 degrees. This ensures that the vertices of the polygon lie on the circumference of the circle. In conclusion, all regular polygons can be inscribed in a circle, as their vertices lie on the circle's circumference.

Answer:

Step-by-step explanation:

Triangle MNP is a right triangle with the following values:

Interior angles of a triangle sum to 180°. Therefore:

m∠M + m∠N + m∠P = 180°

m∠M + 58° + 90° = 180°

m∠M + 148° = 180°

m∠M = 32°

To find the measures of sides MN and NP, use the Law of Sines:

\(\boxed{\begin{minipage}{7.6 cm}\underline{Law of Sines} \\\\$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$\\\\\\where:\\ \phantom{ww}$\bullet$ $A, B$ and $C$ are the angles. \\ \phantom{ww}$\bullet$ $a, b$ and $c$ are the sides opposite the angles.\\\end{minipage}}\)

Substitute the values into the formula:

\(\dfrac{MN}{\sin P}=\dfrac{NP}{\sin M}=\dfrac{PM}{\sin N}\)

\(\dfrac{MN}{\sin 90^{\circ}}=\dfrac{NP}{\sin 32^{\circ}}=\dfrac{8}{\sin 58^{\circ}}\)

Therefore:

\(MN=\dfrac{8\sin 90^{\circ}}{\sin 58^{\circ}}=9.43342722...\)

\(NP=\dfrac{8\sin 32^{\circ}}{\sin 58^{\circ}}=4.99895481...\)

To find the perimeter of triangle MNP, sum the lengths of the sides.

The conic section is ELLIPSE.

The correct graph of the system of equations is D) The graph shows a line with an x-intercept at 4 comma 0 and a y-intercept at 0 comma negative 1. There is a second line with an x-intercept at 4 comma 0 and a y-intercept at 0 comma negative 12.

What is the system of equations?

A system of equations is a set of two or more equations with the same variables. The goal of a system of equations is to find the values of the variables that simultaneously satisfy all the equations in the system.

The given equations are

3x + y = 12

x + 4y = 4

To graph the system of equations, we can start by finding the x-intercepts and y-intercepts of each line.

The x-intercept is the point where the line crosses the x-axis, which means that the y-value is 0. To find the x-intercept, we can set y = 0 and solve for x:

3x + y = 12

3x + 0 = 12

3x = 12

x = 4

So, the x-intercept of the first line is (4, 0).

Next, we can find the y-intercept, which is the point where the line crosses the y-axis, meaning that the x-value is 0. To find the y-intercept, we can set x = 0 and solve for y:

3x + y = 12

0 + y = 12

y = 12

So, the y-intercept of the first line is (0, 12).

We can repeat this process for the second line to find its x-intercept and y-intercept:

x + 4y = 4

x + 4 * 0 = 4

x = 4

So, the x-intercept of the second line is (4, 0).

Next, we can find the y-intercept by setting x = 0:

x + 4y = 4

0 + 4y = 4

4y = 4

y = 1

So, the y-intercept of the second line is (0, 1).

Now that we have found the x-intercepts and y-intercepts of each line, we can plot these points on a coordinate plane and draw lines through them to obtain the graph of the system of equations.

The graph shows a line with an x-intercept at (4, 0) and a y-intercept at (0, 12). There is a second line with an x-intercept at (4, 0) and a y-intercept at (0, 1).

Therefore, the correct graph of the system of equations is D) The graph shows a line with an x-intercept at 4 comma 0 and a y-intercept at 0 comma negative 1. There is a second line with an x-intercept at 4 comma 0 and a y-intercept at 0 comma negative 12.

The probability that a randomly picked fruit will weigh between 362.8 grams and 374.9 grams can be calculated using the standard normal distribution and the z-score formula .

To find the probability, we need to calculate the z-scores for the lower and upper bounds. The z-score is given by (X - μ) / σ, where X is the value, μ is the population mean, and σ is the population standard deviation.

For the lower bound, the z-score is (362.8 - 376) / 11 ≈ -1.2, and for the upper bound, the z-score is (374.9 - 376) / 11 ≈ -0.1091. Using a standard normal table or calculator, we can find the corresponding probabilities for these z-scores.

The probability corresponding to the lower z-score is approximately 0.1151, and the probability corresponding to the upper z-score is approximately 0.4573. To find the probability within the range, we subtract the lower probability from the upper probability:

0.4573 - 0.1151 = 0.3422. Therefore, the probability that a randomly picked fruit will weigh between 362.8 grams and 374.9 grams is approximately 0.3422, or 34.22%.

There are 15,504 ways to randomly select a team of 5 people from a group of 20 people

If there are 20 people trying out for a team, the number of ways to select a team of n people can be calculated using the formula for combinations, which is:

C(20, n) = 20! / (n! * (20 - n)!)

where C(20, n) represents the number of ways to select n people from a group of 20 people.

For example, if we want to select a team of 5 people, we can plug in n = 5 and calculate:

C(20, 5) = 20! / (5! * (20 - 5)!) = 15,504

Therefore, there are 15,504 ways to randomly select a team of 5 people from a group of 20 people. Similarly, we can calculate the number of ways to select teams of different sizes by plugging different values of n into the formula for combinations.
