# 3 Multi-step response questions

Question 1

Question 2

Question 3

• Hey, I just wanna give some heads-up for these questions, I heard they are really easy however: One of the questions for Logistic Models will ask for the RATE where the function moves the fastest, so we need find the infliction point and plug back to the Differential Equation to find that RATE.

• The other thing is that one question is Newton's Colling question. SIt is reallyimilar to Exponential Growth; we just include that room temperature constant.

• OK. Sounds good.

• Is the Bouty Okay?

I have not seen the questions yet. But, again I get 80% of the bounty which is low for the time pressure. Without time pressure, the bount is fine if questions are not hard.

• Awesome Let's start then

• So, there is no time-pressure then? I can respond in 24 hours?

• Working on them now.

• There's a 2 hours limit, but you can go over a couple of minutes.

• With time pressure, the bounty is low.

• I will tip you then

• Done......

• Question 1 - Part A: The equation of the tangent line at the point (0, 3) is y = 3x + 3. - Part B: The second derivative at (0, 3) is 6. The concavity of the solution curve at this point is concave up, indicating that the curve bends upwards like a cup. - Part C: The particular solution with initial condition f(0) = 3 is y = f(x) = 3 - 3sin(x^2 + x).

• Last part seem to be wrong!

• Question 2: - Part A: The differential equation according to Newton's Law of Cooling is dy/dt = -k(T + 16). - Part B: The temperature of the chili after 4 hours is -4.08°C. - Part C: The chili's temperature will be -12°C at t = 7.85 hours.

• Question 3 : - Part A: P(t) = 14000 / (1 + 4.8333 * e^(-4t)) - Part B: The largest rate of increase in the number of bacteria is 28000 bacteria per day. - Part C: The maximum number of bacteria is 14000. This is the carrying capacity of the logistic model, which is the limit to the growth of the population due to environmental constraints.

• Part (A) seem to be wrong.

• Kav, I have two 20 MCQ questions Projects regarding Calculus 2. Would you like to do it?

When do you want to send those?

• What's the best time for you?

• I can do now or 5 pm Pacific Time. Let me know.

• I only need the letter answer so ABCD

• For Question 1, letter C, I found: 3 sin(x^2 + x) + 3; your answer is the SAME as mine but negative sin.

• Not the same. Yours is Sin, correct answer is Cosine (…)
