The normal monthly precipitation P (in inches) in Juneau, Alaska for each month of the year can be approximated by the model P=0.00053t^5−0.02157t^4+0.2854t^3−1 .412t^2+2.19t+3.4, where t=1 represents January.
1. Sketch a graph of the model for
1≤t≤12.

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6

The function f(x)= x5+ ( x + 3)2 is used to create a table. if x = -1 then what is f(x)?
