Answer:
-4 sqrt(7)/7
Step-by-step explanation:
csc theta = -4/3
csc theta = hypotenuse / opposite side
hypotenuse = 4
opposite = 3
Using the pythagorean theorem
a^2 + b^2 = c^2
3^2 + b^2 = 4^2
9+b^2 = 16
b^2 = 16-9
b^2 = 7
Taking the square root
sqrt(b^2) = sqrt(7)
b = sqrt(7)
We are in the third quadrant so only tan and cot are positive
that means the x and y values are "negative" so a = -3 and b = - sqrt(7)
sec theta = hypotenuse / adjacent
= 4/ - sqrt(7)
rationalizing
-4 sqrt(7)/ sqrt(7)* sqrt(7)
= -4 sqrt(7)/7
Answer is D
Please mark me as brainless if right
If you add all the numbers on the right together you get -35 then you divide by 5 which gives you the average of -7*F
Answer:
30.1%
Step-by-step explanation:
Find the percent that was US exports by dividing 6.2 by 20.6, then multiplying it by 100
(6.2/20.6) x 100
= approximately 30.1
So, approximately 30.1% of the trade was US exports
