I'm not going to ask for a whole test, I just want to know what exactly this question is asking and how I would go about doing it.

The function f(x) has the value f(−1) = 1. The slope of the curve y = f(x) at any point is given by the expression = (2x + 1)(y + 1).

Write an equation for the line tangent to the curve y = f(x) at x = − 1.

I'm not sure if it wants me to write the equation of the tangent line, or find it at this point. I already know how to find the answer if it is asking me for the tangent line, but I don't know how I would go about finding it at x=-1. Would I do it normally, or would i somehow plug in negative one?

Rabbits on a particular island increase at a rate directly proportional to 6250-R(t), where R(t) is the number of rabbits and t is years (t>0). We also know that R(0)=2000 and R(7)=5000.

Find R(t) as a function of t only.

I know I want to write the equation as something like Y=Ce^kt. C being the initial amount, T being time and Y being the ending amount. I don't think this i correct though, as k doesn't come into account. Need some help here.

I'm stuck on this particular question.

A weak acid with an initial pH of 3.2 was titrated with a strong base. 15 mL of 0.1 M NaOH was added to the acid to reach the equivalence point at a pH of 8.6. What would you expect the approximate pH of the analyte to be after the first 5 mL of 0.1 M NaOH was added?

3.4

8.6

5.1

7.2

I think its 5.1, but I'm not sure. Can someone explain their answer?

Question 6 (1 point)

Question 6 Unsaved

In the chemical reaction where 0.1 M of N2O4(g) is converted to 2NO2(g), what are the concentration values of NO2(g) in the ICE table?

N2O4(g) 2NO2(g)

Question 6 options:

Initial = 0 M, Change = x, Equilibrium = 0 - x

Initial = 0 M, Change = 2x, Equilibrium = 0 + 2x

--> Initial = 0 M, Change = 2x, Equilibrium = 0 + x

Initial = 0.1 M, Change = x, Equilibrium = 0.1 M - x

Question 7 (1 point)

Question 7 Saved

The reaction below has an equilibrium constant of 3.4.

2SO2(g) + O2(g) 2SO3(g)

At a point during the reaction, the reaction quotient is 1.6 × 10-2. In which direction will the reaction proceed to establish equilibrium?

Question 7 options:

-->From left to right

The reaction is already at equilibrium

From right to left

In the reverse

Question 1 (1 point)

Question 1 Saved

For the following reaction, the partial pressures are listed in the table. If the Kp of the reaction is 3, in which direction would the reaction need to proceed in order to establish equilibrium?

2SO2(g) + O2(g) 2SO3(g)

Question 1 options:

Q = Kp, so the reaction is at equilibrium.

-->Since Q < Kp, the reaction must proceed to the right.

Since Q > Kp, the reaction must proceed to the left.

Since Q > Kp, the reaction must proceed to the right.

The question asks what the the values of A and B are on a given curve in the family Ay^2 - x^2 y +x^2= B. They gave me the point whcih the line is tangent to the curve wich is (6,11) and the slope wich is 4.

I already found the tangent line wich is Y=4x-13 and the slope formula for the curve wich is (2xy+2x)/(8-x^2). I'm unsure about where to go from here.

I think I'm supposed to set the denominator equal to zero and then solve for A and B that way, but that doesn't seem right. Could someone give me a little direction?

I would prefer for the answer not to be given if possible. Thank you.

Could someone help me with this chem question?

What is the value of arccos (-1) in radians. I came out to π^2/180 but my homework answersheet disagrees with me. It gave me either π/4, π/2, 0, or π.
