A company charges a flat rate of $150 plus $0.60 per pound to transport freight in the metro area. This cost is represented by the function below where w is the weight of the freight in pounds and c(w) is the cost given the weight of the freight. How much does Ferdinand Freight Company charge to transport freight weighing 1,500 pounds? c(w) = 150 + 0.60w

Step-by-step explanation:

1050

Step-by-step explanation:

150+.60(1500)=1050

.60*1500=900

900+150= 1050

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
