The comparison test, [tex]$\sum_{n=1}^{\infty} a_{n}$[/tex] diverges since [tex]$\sum_{n=M}^{\infty} b_{n}$[/tex] diverges.
Suppose that [tex]$\sum_{n=1}^{\infty} a_{n}$ and $\sum_{n=1}^{\infty} b_{n}$[/tex] are series with positive terms. We assume that does not exist and that [tex]$\sum_{n=1}^{\infty} b_{n}$[/tex]diverges.
To prove that [tex]$\sum_{n=1}^{\infty} a_{n}$[/tex] also diverges, we will use the comparison test. Since [tex]$\sum_{n=1}^{\infty} b_{n}$[/tex] diverges, we can find a number M such that [tex]$\sum_{n=M}^{\infty} b_{n}$[/tex] diverges. Since [tex]$\lim_{n\rightarrow \infty} \frac{a_{n}}{b_{n}}$[/tex] does not exist, we can find a number N such that for all [tex]$n \geq N$, $\frac{a_{n}}{b_{n}} > 1$[/tex].
Now, for any [tex]$n \geq \max \{M,N\}$[/tex], we have [tex]$\frac{a_{n}}{b_{n}} > 1$[/tex]. Thus, [tex]$a_{n} > b_{n}$[/tex]. By the comparison test, [tex]$\sum_{n=1}^{\infty} a_{n}$[/tex] diverges since [tex]$\sum_{n=M}^{\infty} b_{n}$[/tex] diverges.If the ratio of two series with positive terms,[tex]$\sum_{n=1}^{\infty}a_n$[/tex] and [tex]$\sum_{n=1}^{\infty}b_n$[/tex], does not converge to a limit as n approaches infinity and [tex]$\sum_{n=1}^{\infty}b_n$[/tex] diverges, then [tex]$\sum_{n=1}^{\infty}a_n$[/tex] must also diverge.

two planes take off from the same airstrip. the first plane flies west for 150 miles and then flies 30 degrees south of west for 220 miles. the second plane flies east for 220 miles and then flies x degrees south of east for 150 miles. if x < 30, which plane is farther from the airstrip after the second leg? justify your answer.
The first plane is farther from the airstrip after the second leg
Which plane is farther from the airstrip after the second leg?The first plane
Initial distance = 150 miles west
Additional distance = 220 miles 30 degrees SW
This means that
Additional distance = 220 * cos(30) miles SW
Additional distance = 190.53 miles
Total distance = 150 + 190.53 = 340.53
The second plane
Initial distance = 220 miles east
Additional distance = 150 miles x degrees SE
This means that
Additional distance = 150 * cos(x) miles SW
Total distance = 220 + 150 cos(x)
Given that
x < 30
We have
Second plane < First plane
220 + 150 cos(x) < 340.53

A 83-inch candle burns down in 5 hours. Assuming the candles are the same
thickness and make (that is, directly proportional), how long would it take a 15-inch
candle to burn down?
Step-by-step explanation:
83 in burn in 5 hours.
so, we have a 83/5 speed ratio.
directly proportional means
y = kx
with k being constant for all values of x.
83 = k×5 = 5k
k = 83/5
15 in burn in x hours.
therefore,
15 = 83/5 × x
75 = 83x
x = 75/83 hours
this can be also calculated like this :
because of the direct proportionality, 15/x must have the same ratio as the original 83/5.
83/5 = 15/x
83x/5 = 15
83x = 75
x = 75/83 hours = 0.903614458... hours

?
12
74°
Answer: We can use trigonometry to solve this problem.
Let x be the length of the ladder, and h be the height of the ladder.
We can use the tangent function to relate the angle of elevation, the length of the ladder, and the height of the ladder:
tan(74°) = h / x
We know that x = 12 ft and we can find h.
We can cross multiply and solve for h:
x * tan(74°) = h
12 * tan(74°) = h
We can use a calculator to find the value of h, this will give us the height of the ladder.
Finally, we can use the Pythagorean theorem to find the length of the ladder:
x^2 = h^2 + 12^2
x = √(h^2 + 12^2)
Round your answer to the nearest tenth, we have x = √(h^2 + 12^2)
We can use the value of h to find the length of the ladder.
However, without the value of h it is not possible to find the length of the ladder.

Suppose that the annual amount of rainfall (in million tons) accumulated in a lake follows a gamma distribution with alpha = 3 and gamma = 5.
a) Find the expected annual rainfall accumulated in this lake.
b) Find the standard deviation of the annual amount of rainfall in this lake.
c) Find P(X < 4), use R.
d) Find P(2 < X < 5), use R

c) Pgamma(4, shape = 3, scale = 5)
d) Pgamma(5, shape = 3, scale = 5) - Pgamma(2, shape = 3, scale = 5)
Gamma Distribution Probabilitiesa) The expected annual rainfall accumulated in this lake is given by the mean of the gamma distribution, which is alpha * gamma. In this case, the expected annual rainfall is 3 * 5 = 15 million tons.
b) The standard deviation of the annual amount of rainfall in this lake is given by the square root of the variance, which is the square root of alpha * gamma². In this case, the standard deviation is the square root of 3 * 5² = 15 million tons.
c) To find P(X < 4), we can use the cumulative distribution function (CDF) of the gamma distribution. In R, we can use the pgamma() function to find the CDF of the gamma distribution at a given value.
pgamma(4, shape = 3, scale = 5)
This will return the probability that X is less than 4, which is the cumulative probability.
d) To find P(2 < X < 5), we can use the cumulative distribution function (CDF) of the gamma distribution. In R, we can use the pgamma() function to find the CDF of the gamma distribution at a given value.
pgamma(5, shape = 3, scale = 5) - pgamma(2, shape = 3, scale = 5)

When Boris bought his house, he got his mortgage through a bank. The mortgage was a personal, amortized loan for 91500, at an interest rate of 3.3% , with monthly payments for a term of 40 years.
Answer: As the loan is amortized, Boris will make a series of equal payments each month for the duration of the loan, with each payment comprising of both interest and principal. The amount of interest in each payment will decrease over time, while the amount of principal in each payment will increase.
To calculate the monthly payments, we can use the formula:
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]
Where:
M = monthly payment
P = the principal or the loan amount = 91500
i = interest rate as a decimal = 3.3%/12 = 0.00275
n = total number of payments = 40 years x 12 months/year = 480
By substituting the values in the formula:
M = 91500 [ 0.00275 (1 + 0.00275)^480 ] / [ (1 + 0.00275)^480 - 1]
M = $439.65
So the monthly payment that Boris will make is $439.65. This amount will stay the same throughout the loan term, but the proportion of interest to principal in each payment will change as the loan is amortized.

A percentage can be specified.In mathematics, a percentage is a number any figure that is stated as a proportion of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. The "%" symbol, however, is frequently used to denote it. The % amount has no dimensions and is flat. Because the numerator of percentages is 100, they are effectively fractions. To show that a number is a percentage, the percent sign (%) should be put in front of it. On a test, for instance, you would receive a 75% if you gave the answer 75 out of the total questions.
Here,
Given :

Angela observes that a drone is flying horizontally at a constant height of 5m above the ground. If the drone is flying in the opposite direction from Angela's location at a speed of 1m/s determine the rate at which the angle of elevation (theta) decreases at the moment when (theta)=pi/6
The rate of change of the angle of elevation is approximately - 2.597 degrees per second (-0.045 radians per second). (Correct choice: C)
How to determine the rate of change of the angle of elevation
In this problem we find the case of a drone that travels horizontally, at constant height (h), in meters. The rate of change of the angle of elevation (θ'), in degrees per second, can be found from trigonometric functions and derivatives:
tan θ = y / x
Where:
x - Horizontal distance, in meters. y - Vertical distance, in meters.By derivatives:
sec² θ · θ' = - y · x⁻² · x'
θ' = - (y · x⁻² · x') / sec² θ
Where x' is the speed of the drone, in meters per second.
If we know that y = 5 m, θ = π / 6 and x' = 5 m / s, then the rate of change of the angle of elevation is:
x = y / tan θ
x = (5 m) / tan (π / 6)
x ≈ 2.887 m
θ' = - [(5 m) · (2.887 m)⁻² · (5 m / s)] / sec² (π / 6)
θ' ≈ - 2.597 degrees per second (- 0.045 radians per second)

A number is multiplied by 6, and that product is added to 4. The sum is equal to the product of 2 and 23. Find the number.
Answer:
The number is 7
Step-by-step explanation:
1. Create the equation needed to solve this
Lets think of a number as x. We have a number multiplied by 6 and have 4 added to it.
We get:
6x + 4
Now this sum is equal to the product of 2 and 23. We connect this to get
6x + 4 = 2(23)
We can simplify this to
6x + 4 = 46
2. Solve for x
6x + 4 = 46
Subtract 4 from both sides
6x = 42
Divide both sides by 6
x = 7
Therefore the number is 7

a. Find the initial quality of radioactive material
b. Hoy many more years will it take for the amount of radioactive material to reduce to 0.2 g?
a. The initial quantity of radioactive material is 0.68 g.
b. It will take an additional 7.15 years for the amount of radioactive material to reduce to 0.2 g.
a. In order to find the initial quality of radioactive material, we will use the formula:
Initial Quality = Final Quantity * (1 - Reduction Rate)^Years
We know that -
the final Quantity is 1.52 g, the reduction rate is 18% (or 0.18), and the number of years is 4.
Initial Quantity = 1.52 g * [tex](1 - 0.18)^4[/tex]
Initial Quantity = 1.52 g * 0.452
Initial Quantity = 0.68 g
Hence, the initial quantity of the radioactive material is 0.68 g.
b. In order to find how many more years it will take for the amount of radioactive material to reduce to 0.2 g, we will use the formula:
Years = log(Final Quality / Initial Quality) / log(1 - Reduction Rate)
We know that -
the final quality is 0.2 g, the initial quality is 0.68 g, and the reduction rate is 18% (or 0.18).
Years = log(0.2 / 0.0.68) / log(1 - 0.18)
Years = 7.15
Therefore, it will take an additional 7.15 years for the amount of radioactive material to reduce to 0.2 g.

The circumference of a personal sized pizza at center court is 12.56 inches. Their large pizza is three times the diameter as the personalized sized pizza. What is the area of the large pizza?
The area of the large pizza is approximately equal to 112.984 square inches.
How to determine the area of a large pizza
Herein we need to determine the area occupied by a large pizza (A), in square inches, and based on given input by circumference of a small pizza (s), in inches. Then, we need the following formulas:
Circumference
s = π · D
Area
A = 0.25π · D²
Where D is the diameter, inches.
First, determine the diameter of the small pizza:
D = s / π
D = 12.56 / π
D ≈ 3.998 in
Second, calculate the diameter of the large pizza:
D' = 3 · (3.998 in)
D' = 11.994 in
Third, obtain the area of the large pizza:
A = 0.25π · (11.994 in)²
A ≈ 112.984 in²

The largest value of all four operations is
The largest value of all four operations is 54
How do you determine the largest number?In order to determine the largest value of all the four operations, one needs to plug in the values into the different operations given and then generate their values. By so doing, the following deductions are made:
(f * g)(3) = 2 * (3^2) * (3 - 4 * (2 * 3)) = 54
(f - g)(4) = 2 * (4^2) - (4 - 4 * (2 * 4)) = 40
f(g(2)) = 2 * (2^2) = 8
(f + g)(1) = 2 * (1^2) + (1 - 4 * (2 * 1)) = -3

Use the figure below to select the classification of each set of angles in a)-d)
The classification of the angles are;
a) ∠3 and ∠5; Alternate Angles
b) ∠1, ∠2 and ∠3; three interior angles of a triangle.
c) ∠2 and ∠3; Complementary angles
d) ∠4 and ∠5; Supplementary angles
How to classify angles?We know that the sum of angles in a triangle is 180 degrees and as such it means that ∠1, ∠2 and ∠3 are classified as three interior angles of a triangle.
We know that alternate angles are defined as angles that occur on opposite sides of the transversal line and have the same size. Thus;
∠3 and ∠5 are alternate angles.
Since ∠1 is 90 degrees, then it means that ∠2 and ∠3 are complementary angles.
Similarly, ∠4 and ∠5 are called supplementary angles because they sum up to 180 degrees.
