D) a horizontal translation and a reflection across a verticle line
D. graph D
Explanation
Step 1
graph the function as a line
convert
to graph, find 2 coordianates
a) when x=0
b) when
x=-4
now, using two points draw a line
Step 2
we are looking fro values under this line, so the answer is
D. graph D
From my understanding you ahould use the trig function cos to solve this.
cos(c) = 15/25 or 0.6
if you have this following function on your calculator I suggest using it:
cos ^{ - 1}
by using the function like so:
cos^{ - 1} (0.6
you should get about 53.13° (rounding to the nearest hundredth)
Hope this helped.
Sum to infinite for
1) arithmetic series is always divergent, sum is infinite.
2) geometric series is convergent if -1 < common ratio < 1 otherwise it is divergent.
b) is correct , (r = 5) > 1
198 is the answer. So write it.
