<span>The range of Cos(x) is [-1,1]. Therefore the range of ln(Cos(x)) will be the image of [-1,1] using the natural log function. However, the domain of ln(x) is (0,infinity) and the log function is strictly increasing with vertical asymptote at "x=0". Therefore, the range of ln(Cos(x)) will be:
(- infinity, ln(1) ] = (-infinity, 0] !</span><span>so its true </span>
Answer:
Alma got home at 3:27
Step-by-step explanation:
2:45+30 min=3:15
3:15+12 min = 3:27
The square has area 8*8=64, the rectangle has area 7*4=28, and the triangle has area 7*6/2=21. Their sum is 64+28+21=113.
2x + x - 1 x
= ------------------ * ---------
x(x - 1) 8
3x - 1
= --------------
8x - 8
