The first equation is
(Equation 1)
The second equation is (Equation 2)
Putting the value of x from equation 1 in equation 2.
we get,
by simplifying the given equation,
Using discriminant formula,
Now the formula for solution 'x' of quadratic equation is given by:
Hence, these are the required solutions.
Answer:
{5π/6, 11π/6}
Step-by-step explanation:
Since you have memorized the trig values of common angles, you know tan(π/6) = 1/√3, so cot(π/6) = √3.
The solution to this equation is ...
cot(θ) = -√3
so θ = -π/6 or, in the domain of interest, 11π/6. There is a corresponding quadrant II angle, 5π/6.
Answer:
is scientific notation of 78 billion
Step-by-step explanation:
For scientific notation , follow the following notation:
-------->(equation 1)
Let,
In standard form
or
As decimal point move 10 places from right to left, therefore
b = 10
Put the value of 'a' and 'b' in (equation 1)
is scientific notation of 78 billion
