Answer: cos(76)</h3>
=========================================================
Explanation:
The original expression is of the pattern cos cos + sin sin. This pattern matches the second identity in the hint. Specifically, we'll say the following:
cos(A - B) = cos(A)cos(B) + sin(A)sin(B)
cos(A)cos(B) + sin(A)sin(B) = cos(A - B)
cos(94)cos(18) + sin(94)sin(18) = cos(94 - 18)
cos(94)cos(18) + sin(94)sin(18) = cos(76)
----------
We can verify this by use of a calculator. Make sure your calculator is in degree mode.
- cos(94)cos(18) + sin(94)sin(18) = 0.24192
- cos(76) = 0.24192
Both expressions give the same decimal approximation, so this helps confirm the two expressions are equal. You could also use the idea that if x = y, then x-y = 0. Through this method, you'll subtract the left and right hand sides and you should get (very close to) zero.
Answer:
C) p + 3 < 20
Step-by-step explanation:
Since the max is 20, it has to be < 20
p + 3 < 20
Answer:
the big tank can hold 2027.37 m³of water
10 small tanks can be filled
Step-by-step explanation:
r = 11, h = 16
V = (1/3)πr²h
V = (1/3)121π(16)
1936π/3 = 2027.37
2027.37/200 = 10. 136
10 tanks
