Answer:
Step-by-step explanation:
We can use the point-slope formula given by:
The given line passes through the
point (-3,2) and having slope .
We substitute the given point and slope to get:
we clear the fraction to get;
Or in standard form:
<h3>2 Answers: Choice B, Choice C</h3>
The rule we use here is
If the font size is too small, then it says (a^b)/(a^c) = a^(b-c)
We subtract the exponents when dividing exponentials like this. The bases must be the same.
So this means the exponents 13 and 3 subtract to get 13-3 = 10
We either have an exponent of "13-3" or an exponent of "10" as an equivalent expression. The base stays at 2 the entire time.
note that :
cot150 = 1/tan150
cos390 = cos(360+30) = cos30
