2ways you can solve that is by multiplying 9 by 1 then by 5 or 9by 5 then by 1
ANSWER
EXPLANATION
The given problem is
This is defined if and only if
Even the given expression can be simplified to obtain:
The exclusion is
The answer would be positive 5
Cos(x°) = (√3)/2
cos⁻¹[(√3)/2] = x°, that means x° = 30°
Answer:
I would stay direct vartation
Step-by-step explanation:
For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
