4vir4ik [10]
Remember that the general decay equation is:
y=A(1-r)^{x}
where 
y is the amount after a time x
A is the initial amount 
r is the the decay percent in decimal form

The first ting we are going to do is find r by dividing our <span>decay rate of 25% by 100%: </span>r= \frac{25}{100} =0.25.
We also know from our problem that y=64. Lets replace y and r in our formula:
64=A(1-0.25)^{x}
64=A(0.75)^{x}
We know now that our decay rate is 0.75, and since 0.75<1, we can conclude that this situation represents exponential decay.

Now, to find the initial amount, we are going to solve our equation for A:
64=A(0.75)^{x}
A= \frac{64}{0.75 ^{x} }
Notice that A will depend on the number of ours x. <span />

-10/5+2(7-9)^2
Oksana_A [137]
Answer: -4

Reasoning: so first you need to subtract the 7 from the 9 to get -2. Then you square it to get 4 because a negative 2 times -2 is 4. Then you multiply the 4 by the 2 to get 8. You can simplify the -10/5 to -1/2 and multiply that by the 8 to get -8/2 which simplified out to -4.


I hope that helps.
