He has 20 guppies?
This is what I got from the information. Unless they had eggs.
Lets say g represents how many games played
Each place has an initial charge for shoes show that will be added to games times cost per game.
Eastside=2.25+3g
Westside=1.75+2.5g
Now subtract westside from east side
Cost difference=.5+.5g
Answer:
x = 20
Step-by-step explanation:
The sum of the opposite interior angles of a triangle is equal to the exterior angle
x + 2x+10 = 70
Combine like terms
3x+10 = 70
Subtract 10 from each side
3x+10-10 = 70-10
3x = 60
Divide each side by 3
3x/3 = 60/3
x = 20
We know that
1 milligrams is equals to-------------> 0.001 <span>grams
then
</span><span>3000 milligrams----------------------> X
X=3000*0.001------> x=3 grams
the answer is
3 grams</span>
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
