Answer:
Cos θ = √7/3
Step-by-step explanation:
From the question given above, the following data were obtained:
Sine θ = √2 / 3
Cos θ =?
Recall
Sine θ = Opposite / Hypothenus
Sine θ = √2 / 3
Thus,
Opposite = √2
Hypothenus = 3
Next, we shall determine the Adjacent. This can be obtained as follow:
Opposite = √2
Hypothenus = 3
Adjacent =?
Hypo² = Adj² + Opp²
3² = Adj² + (√2)²
9 = Adj² + 2
Collect like terms
9 – 2 = Adj²
7 = Adj²
Take the square root of both side
Adjacent = √7
Finally, we shall determine the value Cos θ. This can be obtained as follow:
Adjacent = √7
Hypothenus = 3
Cos θ =?
Cos θ = Adjacent / Hypothenus
Cos θ = √7/3
Answer:
I think the answer is12h?
Answer:
Step-by-step explanation:
When we have a number to a fraction power, we need to note that
- It's the same as taking the denominator root of the base to the numerator power
Basically, for example, 
is the same as 
since the numerator is 1 (
) and the denominator is 2 ().
Applying this same logic to 
-

The formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid is p = s + dgh, where s is the atmospheric pressure, d is the density of the liquid, and gas the acceleration due to gravity.
p = s + dgh
dgh = p - s
h = (p - s)/dg
Which formula represents h in terms of p, s, d, and g? Formula B is correct.
