dust particle 0.000000000778 kg comet 544000000000000 kg The mass of the dust particle can be written in the form a × 10b kg, where a = and b = . The mass of the comet can be written in the form of a × 10b kg, where a = and b = .

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

Apositive number a or the same number a increased by 50% and then decreased by 50% of the result?
