I did 6 problems for you. You can now do the other 4 problems and see how I did it. You need to have the same denominator and the add the fractions together.
Answer:
See answers below
Step-by-step explanation:
Given that sin theta = √3/√7
Opposite =√3
Hypotenuse = √7
Get the adjacent
Adj² = (√7)²-(√3)²
Adj² = 7-3
Adj² = 4
Adj = √4
Adj = 2
Cos theta = adj/hyp = 2/√7
csc theta= 1/sin theta = 1/(√3/√7) =
√7/√3
sec theta= 1/costheta = 1/(2/√7) = √7/2
tan theta= opp./adj = √3/2
cot theta =1/tan theta = 1/(√3/2) = 2/√3
= 2√3/3
Answer:
The ordered pair is not a solution.
Answer:
a. 54,700 is not in correct scientific notation
Arccos is the same thing as inverse cosine which is used when you are looking for an angle measure. Make sure your calculator is in degree mode. Hit 2nd button then cos and you will see this on your screen:
and it is following the parenthesis there that you will enter your decimal. The inverse cosine of .67 is an angle measure of 47.93°
