Answer:
(0, ∞)
Step-by-step explanation:
As x becomes increasingly negative, e^x decreases towards zero (but never touches zero). As x grows without bound, e^x increases without bound.
Thus, the range is (0, ∞).

Answer:
![\cos{W} = \frac{9}{41}](https://tex.z-dn.net/?f=%5Ccos%7BW%7D%20%3D%20%5Cfrac%7B9%7D%7B41%7D)
Step-by-step explanation:
Cosine of an angle:
The cosine of an angle, in a right triangle, is the length of the side adjacent to this angle divided by the hypotenuse.
Length of the largest side:
The length of the largest side is 41, that is, the hypotenuse is 41. The hypotenuse is XW.
WY = 9.
This means that the length of the adjacent side to angle W is 9.
What ratio represents the cosine of ∠W?
Adjacent side has length 9, hypotenuse has length 41. So
![\cos{W} = \frac{9}{41}](https://tex.z-dn.net/?f=%5Ccos%7BW%7D%20%3D%20%5Cfrac%7B9%7D%7B41%7D)
5x - 2 = 8x + 5.
-2 = -5x + 8x + 5
-2 = 3x +5
-7 = 3x
-7/3 = -2.3
