Why can't you calculate the output for rule 6 when the input is −6? Explain.

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

Y=(x+3)(x-4)(x+1)^2 sulutions? multiplicity?

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.
