Answer:
The answer to your question is the third choice secФ = 41/40
Step-by-step explanation:
Data
Opposite side = 9
Adjacent side = 40
hypotenuse = 41
Process
To solve this problem use trigonometric functions. The secant is the trigonometric function that relates the hypotenuse and the adjacent side.
sec Ф = hypotenuse / adjacent side
hypotenuse = 41
adjacent side = 40
then,
secФ = 41/40
Answer:
-3
Step-by-step explanation:
(fg)(-1) is just f(-1) * g(-1). From the graph on the left, we can see that f(-1) is 1, since (-1,1) is on the graph. From the graph on the tight, we can see that g(-1) is -3, since (-1,-3) is on the graph. Now, we just have to multiply 1 and -3: 1*-3 = -3
Answer: -8 and -4
