Answer:

(e) csc x − cot x − ln(1 + cos x) + C

(c) 0

Step-by-step explanation:

(e) ∫ (1 + sin x) / (1 + cos x) dx

Split the integral.

∫ 1 / (1 + cos x) dx + ∫ sin x / (1 + cos x) dx

Multiply top and bottom of first integral by the conjugate, 1 − cos x.

∫ (1 − cos x) / (1 − cos²x) dx + ∫ sin x / (1 + cos x) dx

Pythagorean identity.

∫ (1 − cos x) / (sin²x) dx + ∫ sin x / (1 + cos x) dx

Divide.

∫ (csc²x − cot x csc x) dx + ∫ sin x / (1 + cos x) dx

Integrate.

csc x − cot x − ln(1 + cos x) + C

(c) ∫₋₇⁷ erf(x) dx

= ∫₋₇⁰ erf(x) dx + ∫₀⁷ erf(x) dx

The error function is odd (erf(-x) = -erf(x)), so:

= -∫₀⁷ erf(x) dx + ∫₀⁷ erf(x) dx

= 0

Andy is hanging wallpaper in his kitchen. He is able to cover 2 2/5 of the walls in the room using 6 rolls of wallpaper. What is
faltersainse [42]

Answer: The number of rolls of paper is 2\dfrac{1}{2}.

Step-by-step explanation:  Given that Andy is hanging wallpaper in his kitchen. 6 rolls of wallpaper is used to cover 2\dfrac{2}{5} of the walls.

We are to find the number of rolls of paper used per wall.

We will be using unitary method to solve the given problem.

We have,

2\dfrac{2}{5}=\dfrac{12}{5}.

Now, number of rolls used to cover \dfrac{12}{5} of the walls = 6.

Therefore, number of rolls used to cover 1 wall is given by

\dfrac{6}{\frac{12}{5}}=\dfrac{5\times 6}{12}=\dfrac{5}{2}=2\dfrac{1}{2}.

Thus, 2\dfrac{1}{2} rolls of paper used per wall.

Find the slope of the graph of C
alexandr402 [8]

Step-by-step explanation:

the slope of a line or linear equation is always the factor of the driving variable.

usually in the form of

y = ax + b

x is the variable, and a the slope.

but in our case the variable is called "n".

it does not matter, the same principle applies.

the slope is the factor of n : 1050.

and as the slope is always the ratio y/x, we are looking for a fraction form, and that would be 1050/1.

so, the third answer is correct.
