Solving a Proportion Use proportional reasoning to determine the value of a in the proportion shown below. Three-fifths = StartFraction a + 5 Over 25 EndFraction a = 1 a = 25 a = 10 a = 15

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

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)

Which describes the difference between the graph of f(x)=x^2 and g(x)=-(x^2-2)
