The table below shows the amount of a radioactive compound remaining after X years Sarah is compiling the data into a lab report

including a graph and needs to determine what scale to use which statement is true about her data.
A. the y-intercept of the graph is 900, and the X increases, f(x) approaches 100.
B. the amount of radioactive substance will continue to Decay at a constant rate over time until it reaches the x-axis.
C. the y-intercept of the graph is 900, andaz x increases, f(x) approaches infinity.
D. the x-intercept of the graph is 900, and as X increases, f(x) approaches 100. ​

Answer:

  A. the y-intercept of the graph is 900, and as X increases, f(x) approaches 100.

Step-by-step explanation:

The table can be described by the function ...

  f(x) = 100 +800·2^-x

This is an exponential decay (not a constant-rate decay) from a y-intercept of 900 down to a minimum value of 100 (not zero).

The best description is that of choice A.

What is the smallest multiple of 18 of the form 2A945B, where A and B are digits?
musickatia [10]

Answer:

219456

Step-by-step explanation:

It must end in 0,2,4,6,8 (divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).

The digit sum is 2+A+9+4+5+B=20+A+B.

We want to make A as low as possible because it's a higher digit than B.

If A is as low as possible, we have that the sum is 20+0+7=27. Uh-oh. B has to be even! So A=0 doesn't work.

If A=1, we have that the sum is 20+1+6=27. Yay!

So, the answer is \boxed{219456}
