A. The temperature goes higher-lower-steady/same-lower-same.
B. I do not understand the question
Let A and 4A be the investment amounts.
The total profit is 3480=0.06A+0.20A=0.26A, so Fund A investment, A=3480/0.26=$13384.62, and Fund B is $53538.46.
M = 3. y2-y1 / x2-x1 -- 10-4 / 2-0 = 6/2 =3.
15 tables in a row are needed
I got .115384615
It may be wrong on my part but message me if I messed up because I am actually smart.
