The series as represented in the task content is divergent and hence; diverges.

It follows from the task content that the series defined by the summation expression as represented above is to be identified as divergent or convergent.

It is noteworthy to know that;

If a sequence converges, it means that the limit of the sequence exists as n → ∞. Also, if the limit of the sequence as n → ∞ does not exist, Then, such series is said to diverges.

Therefore, by evaluation as the limit of the expression k sin²k / 1 + k³ as k → ∞ is; Undefined and hence does not exist.

The table to show the number of cups for the colors will be:

Red cups Blue cups

1. 8

2. 16

3. 24

Given that the person is making purple paint in the ratio of 2 cups blue paint to 1/4 cups of red paint.

Therefore, for every 1 cup of red paint, the number of blue paint will be:

= 2 ÷ 1/4

= 2 × 4

= 8 cups

Therefore, to get other values, you simply have to multiply by 8.

2 red paint will be:

= 2 × 8

= 16 blue cups.

Answer: 11.74

Step-by-step explanation:

A rectangle has two pairs of equal sides.

Answer:

[tex]P(x)=x^3-3x^2+16x-48[/tex]

Step-by-step explanation:

Given information:

For any complex number  [tex]z=a+bi[/tex], the complex conjugate of the number is defined as  [tex]z^*=a-bi[/tex].  

If f(z) is a polynomial with real coefficients, and z₁ is a root of f(z)=0, then its complex conjugate z₁* is also a root of f(z)=0.

Therefore, if P(x) is a polynomial with real coefficients, and 4i is a root of f(x)=0, then its complex conjugate -4i is also a root of P(x)=0.

Therefore, the polynomial in factored form is:

[tex]P(x)=1(x-3)(x-4i)(x-(-4i))[/tex]

[tex]P(x)=(x-3)(x-4i)(x+4i)[/tex]

Expand the polynomial:

[tex]P(x)=(x-3)(x^2+4ix-4ix-16i^2)[/tex]

[tex]P(x)=(x-3)(x^2-16(-1))[/tex]

[tex]P(x)=(x-3)(x^2+16)[/tex]

[tex]P(x)=x^3+16x-3x^2-48[/tex]

[tex]P(x)=x^3-3x^2+16x-48[/tex]

The resulting equation of isolation and substitution is  9y⁴-466 y² + 5481 = 0

Given:

{x² + y² = 25

{x²/16 - y²/9 = 1

Zach isolated  x² in the first equation, we have:

x² + y² = 25

x² = 25- y²

Zach then substituted the x² into the second equation:

x²/16 - y²/9 = 1                           (put x² = 25- y²)

(25- y²)²/16 - y²/9 = 1                (Expand the bracket)

(625- 50y²+y⁴)/16 - y²/9 = 1      The LCM of 9 and 16 is 144

( 9(625- 50y²+y⁴) - 16 y² ) /144 = 1         Cross multiply

9(625- 50y²+y⁴) - 16 y² = 144

5625 - 450y² + 9y⁴-16 y² = 144

9y⁴-466 y² + 5625 = 144

9y⁴-466 y² + 5625-144 = 0

9y⁴-466 y² + 5481 = 0  

Therefore, the resulting equation is  9y⁴-466 y² + 5481 = 0

The amount of the monthly payments is $368.34, and the total interest on the loan is $5,100.

The initial amount of money that we borrow is $17,000. We borrow this amount for a total of five years. The interest charged is 6%. We borrowed the money for the purchase of a car. We need to find the monthly payments and the total interest for the loan.

Let the total amount to be paid and the interest be denoted by the variables "A" and "I", respectively.

I = P*R*T

I = $17,000*0.06*5

I = $5,100

The total amount of money to be paid is the sum of the initial amount and the interest charged.

A = P + I

A = $17,000 + $5,100

A = $22,100

The total number of months in five years is 12*5 = 60.

The amount of the monthly payment is the ratio of the total amount to be paid to the total number of months.

M = $22,100/60

M = $368.34

The most appropriate design for the study would be the experiment. We must apply the new repellent to a group of 5 dogs and the popular repellent to another group of 5 dogs. This will allow us to establish if the new repellent is more effective.

The most appropriate research design for this case is the experiment because it will allow us to check if our hypothesis is true.

The research design of experiment should be implemented as follows. First of all we must apply the new repellent to a group of 5 dogs and in parallel, we must apply the popular repellent to another 5 dogs. After a while we must examine them to check the effects of the repellent.

In this way we will know if the new repellent is more effective than the popular repellent. Additionally, we can establish how effective it is taking into account that we used a population of 5 dogs.

The transformation is applied to ΔABC to get the ΔA'B'C' is vertical translation of 6 units downwards.

The triangle has the vertices  A(-2, 3), B(2, 1), and C(1, 0)

They are transformed such that:

A(-2, 3)→A'(-2,-3)

B(2, 1)→B'(2,-5)

A(-1, 0)→A'(-2,-6)

Now, if we pay close attention, we can notice that A's y-coordinate is 6 less than A's.

Similar to A, B and C have coordinates that are 6 units lower than the object's coordinates but with the same x-coordinate.

This demonstrates that the graph undergoes a vertical translation; the graph is translated 6 units lower since the new ordinates are 6 units smaller.

A transformation, or f: X→X', is a function that maps to itself. The transformation will result in the pre-image X becoming the image X'. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, may be used in this transformation.

Kinetic energy is defined as the work required to accelerate a body of a given mass from rest to its stated speed. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Mass - (Measured in Kilogram) - Mass is the amount of matter in a body, regardless of its volume or the forces acting on it.

Velocity - (Measured in Meters per Second) - Velocity is a vector quantity (has both magnitude and direction) and is the rate of change of an object's position with respect to time.

We have that the data is:

The formula to calculate kinetic energy is:

             Ec = m * v²/2

Since it only asks us to calculate the kinetic energy, it is not necessary to clear the formula.

[tex]\boldsymbol{\sf{Ec=\dfrac{158 \ kg*\left(0.42 \ \frac{m}{s}\right)^2 }{2} }}[/tex]

[tex]\boldsymbol{\sf{Ec=\dfrac{158 \ kg*0.1764 \ \frac{m^2}{s^2} }{2} }}[/tex]

[tex]\boldsymbol{\sf{Ec=13.9356 \ kg*\dfrac{m^2}{s^2} }}[/tex]

We work with the units, in this case with m^2 = m*m.

[tex]\boldsymbol{\sf{Ec=13.9356 \boxed{\boldsymbol{\sf{Kg*\frac{m}{s^2} }}}*m }}[/tex]

Newton's units are: Kg*m/s^2.

[tex]\boldsymbol{\sf{Ec=13.9356 \ N*m \longmapsto Joule \ units=N*m}}[/tex]

The speeds when converted are 29.648 km/h and 8.24 m/s

From the question, we have the following parameters that can be used in our computation:

Speed = 16 knots

Also, from the question, we have

1 nautical mile to be 1853 m

This means that

Speed = 16 * 1853 m per hour

Convert meters to kilometers

So, we have

Speed = 16 * 1.853 km per hour

Evaluate the products

Speed = 29.648 km/h

Also, we have

Speed = 16 * 1853 m per hour

Convert hour to seconds

So, we have

Speed = 16 * 1853/3600 m/s

Evaluate

Speed = 8.24 m/s

The cost of the sweater is $ 30 and

1 dollar = 17 pesos, $ 25 = 425 pesos and $ 3 dollar = 51 pesos.

Mathematical Operations are activities or mathematical processes used to solve given problems. The most used mathematical activities are adding, subtracting, multiplying, and dividing.

The basic operations and their symbols are given below
Addition (+); Subtraction (-); Division (÷);  and Multiplication (x).  

Here we have

Priya exchanged 250 dollars for 4250 pesos  

[Here we used division and multiplication to solve the problem ]

Then the value of 1 dollar in pesos = [tex]\frac{4250}{250}[/tex] = 17 pesos

⇒ 1 dollar = 17 pesos

⇒ 25 dollars = 25 × 17 = 425 pesos

⇒ 3 dollar = 3 × 17 = 51 pesos

Given the cost of the sweater = 510 pesos  

The cost of the sweater in pesos = [tex]\frac{250}{4250} \times510[/tex] = 30

line g:   P1=(x1,y1) = ( -6,1)    and parallel to  f  ( same slope)

use point-slope, again  

y-y2 = m(x-x1)

y-1=[tex]\frac{1}{6}[/tex](x-(-6))

y-1 =[tex]\frac{1}{6}[/tex](x+6)

y-1 = [tex]\frac{1}{6}[/tex]x +1

Answer:

f(x) = -3x+1

Step-by-step explanation:

every straight graph has an equation f(x) = m * x + b

when the graph goes up when you look at it from left to right, m is a positive number. when it goes down, then m is negative.
the value of m you can read when you go 1 to the right and then count how many you need to go up/down to meet the graph. in this picture, you need to go down 3.
So m = -3
b is how many you habe to go up (+) or down (-) from the center point 0
so in this case you see on the picture that the graph is hitting the y line on 1

so your equation is -3x + 1
