Ordinary brass contains 61.6% copper, 2.9% lead, 0.2% tin, and 35.3% zinc. how many pounds of each metal would be in 160 lb. of brass?

Step-by-step explanation:

We have been given that ordinary brass contains 61.6% copper, 2.9% lead, 0.2% tin, and 35.3% zinc.

The amount of each metal would be given percent of 160 pounds.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
