Answer:
x = 15 and y = 10
Step-by-step explanation:
It is assumed that 'x' and 'y' are declared as '10' and '15' respectively. Then following the mystery(x, y) function which is pass 10 and 15 as parameter. Then we can follow the logic of the mystery function.
First, temp is assigned to one; that is temp = 10
Secondly, one is assigned to two; that is one = 15
Thirdly, two is assigned to temp; that is two = 10.
Since x and y is same as one and two; we say:
x = one = 15 and
y = two = 10.

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
Answer:
the answer is B
Step-by-step explanation:
b is 3,-4 wich is the same on the graph
dont forget to press the crown :)
Answer:
Area = length x width
21 = (2w-1)w
21 = 2w^2 -w
2W^2 - w -21=0
(2w-7 )(W +3)=0
2W-7=0 or w+3=0
W=7/2 or w=-3
Width cannot be negative.
So width is 7/2=3.5
Then the length is 6
