Find P(A) if P(B)=0.4 and P(A and B)=0.3. Assume A and B are independent
events.

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

Over which interval is the graph of f(x) = x2 + 5x + 6 increasing?

Use the distributive property -7(-2x+u-2)
