Answer:
Answer ≈ 0.022
Step-by-step explanation:
For these types of questions with sin cos or tan, you will need to use a calculator. There is no other way as far as I have seen on the internet to solve this type of problem. Anyways, what you have to do is take your calculator and put in:
sin
sin(2/3+3/5) exactly like that
and the calculator will give this to you:
0.022105703 which you can then round up.
I hope this answer helped you out. If it did I would greatly appreciate it if you could check out my channel The Game Rater(or Nitro Studios the name might change). I would really appreciate that. Thanks.

If a sample of gas is a 0.622-gram, volume of 2.4 L at 287 K and 0.850 atm. Then the molar mass of the gas is 7.18.
<h3>What is an ideal gas equation?</h3>
The ideal gas equation is given below.

The equation can be written as

Where M is the molar mass, P is the pressure, V is the volume, R is the universal gas constant, T is the temperature, and m is the mass of the gas.
Then the molar mass of a 0.622-gram sample of gas has a volume of 2.4 L at 287 K and 0.850 atm.
V = 2.4 L = 0.0024
P = 0.85 atm = 86126.25 Pa
T = 287 K
m = 0.622
R = 8.314
Then we have

Then the molar mass of the gas is 7.18.

Answer:
-19
Step-by-step explanation:
Evaluate -x^2 - 5 x y + 5 y^3 where x = -2 and y = -1:
-x^2 - 5 x y + 5 y^3 = -(-2)^2 - -2 (-5) + (-1)^3×5
(-2)^2 = 4:
-4 - -5 (-2) + 5×(-1)^3
(-1)^3 = -1:
-4 - -5 (-2) + 5×-1
-5 (-2) = 10:
-4 - 10 - 5
-4 - 10 - 5 = -(4 + 10 + 5):
-(4 + 10 + 5)

Answer:
(f-g)(x)
= -x^2 - 2x + 2
Step-by-step explanation:
(f-g)(x) means
f(x) - g(x)
= x - 2 - (x^2+3x-4)
distribute the subtraction to all three of the last terms.
= x - 2 - x^2 - 3x + 4
combine like terms
= -x^2 - 2x + 2
Answer:
1190 m^3
Step-by-step explanation:
l = 1700 cm = 17 m
b = 14 m
h = 1000 cm = 10 m
Total volume = l × b × h
= 17 × 14× 10
= 2380 m^3
since it is half filled ,
Volume is half , so,
volume of water in pond = 2380 ÷ 2
= 1190 m^3
