Answer: This does not represent a function
Step-by-step explanation: To tell if this relation is a function, we can use the vertical line test. In other words, if we can draw a vertical line that passes through more than one point on the graph, then the relation is not a function. In this situation, it's possible to have a vertical line that passes through more than one point so it's not a function.

Answer:
Step-by-step explanation:
You have the right numbers, but the wrong accounts.
__
Let x represent the amount invested at 8% (the highest rate). Then the total interest is ...
.08x +.03(3000 -x) = .04(3000)
.05x = .01(3000) . . . . subtract .03(3000)
x = 3000/5 = 600
Matthew invested $600 at 8%, $2400 at 3%.

You may notice that the overall interest rate is 4%, closer to 3% than to 8%. That means more of the money must be invested at 3% than at 8%.
Answer:
Step-by-step explanation:
a) The half-life equation is given by:
b) Using the decay equation we have:
we need to find t when
Therefore, it will take 4820 years to decay to half the original amount.
