Find the charge on the capacitor in an LRC-series circuit at t = 0.05 s when L = 0.05 h, R = 3 Ω, C = 0.008 f, E(t) = 0 V, q(0) = 4 C, and i(0) = 0 A. (Round your answer to four decimal places.) C

Determine the first time at which the charge on the capacitor is equal to zero. (Round your answer to four decimal places.) s

DO NOT DO THE GRAPH OR THE DOMAIN OR RANGE PART. THOSE DO NOT COUNT. WE ARE NOT DOING THEM IN MATH 1003.Find the factors that are common in the numerator and the denominator. Then find the intercepts and asymptotes. (If an answer does not exist, enter DNE. Enter your asymptotes as a comma-separated list of equations if necessary.)

r(x) =

Given the following rational function:

            F(X) = (2X^2 - 20) / [( X - 5 )^2]

1. Find all horizontal and vertical asymptotes

2. Find the first derivative of F(X) and simplify

3. Find the critical values for X and determine if they are at a maximum or minimum, using the First Derivative Sign Test.

4. Find the Second Derivative and Use it to confirm your answers to part c. You may keep the 2nd derivative in “rough” form and simply substitute in the X value found in part c to see if you confirm a max or a min.

4x-2y-2z=2
-x-5y+2z=-8
4x-5y+z=11

Please make sure you show all steps numerically, becuse I want to be sure I know how to arrive at the same numbers.

A couple is deciding to invest in the laundromat business. There are two laundromat stores available for sale. They can only afford to buy one of them.

    The annual flow of income from each of the available laundromats is given below:

Laundromat 1: I’(t) = dI(t)/dt = 9000e^(.04t)

Laundromat 2: I’(t) = dI(t)/dt = 12500

The couple has decided to use the Present Value of each of the Laundromats after 8 years, at an annual interest rate of 10%, to compare the value of both investments.

They will buy the Laundromat with the highest Present Value.

1. Find the Present Value of each Laundromat

2. Which Laundromat should the couple buy? Explain.

         Hint: PV(t) = Definite ∫ I’(t)e^(-rt)dt, taken between ( a<t<b)

          Here a=0; b=8

                   r = 10%/100 = .10

I don't understand how to use beats using sum-to-product identity, or this assignment at all.

1. Dealing with vector fields is very common in engineering and science applications. Vector fields are often used to model a moving fluid throughout space, magnetic or gravitational force, and etc.

a. Provide two examples of vector field for engineering or science applications in two and three dimensions

b. Define a conservative vector field. Verify whether the given examples for vector fields in Part 1(a) are conservative? [15 marks]

c. Interpret the fundamental theorem of line integrals for conservative vector fields. Explain this with an example of a force field (i.e. vector field) and compute the work done by the force field in moving a particle from one point to another point along a curved path in three dimensional space.

Explain how to use derivatives to find the top of a hill or the bottom of a valley on a graph?

What does it even mean for a derivative to not exist and why is this involved? And what does that have to do with a derivative of zero?

The rate of growth of the population of rabbits in China is proportional to the current rabbit population. The population after t years is R(t). Write the differential equation for which R(t) is a solution. Your equation should involve an unknown constant

Initially, there are 100 rabbits but the population is increasing at a rate of 20 per year. Use this information to find the unknown constant in part That is, write the differential equation (without an unknown constant) for which R(t) is a solution

Find the population of rabbits in year t. That is, find R(t

Find the time t in which there are 1, 000 rabbits
