Answer: ![y = 650(0.907)^t](https://tex.z-dn.net/?f=y%20%3D%20650%280.907%29%5Et)
This is the same as writing y = 650(0.907)^t
=====================================================
Explanation:
Exponential equations can be of the form y = a*b^t
- a = initial amount
- b = growth or decay factor
In this case, we have
- a = 650 mg to start with
- b = 1 - 0.093 = 0.907 as the decay factor
If we had exponential growth, then we'd compute 1 + 0.093 instead.
Based on those values, we go from y = a*b^t to y = 650(0.907)^t which is the same as writing ![y = 650(0.907)^t](https://tex.z-dn.net/?f=y%20%3D%20650%280.907%29%5Et)
Other exponential forms are possible, but I think this form is the most intuitive. The 0.907 means that 90.7% of the sample remains after each year.
Multiply, and Divide
2/ 2 - 15i
2(2 + 15i)/ (2 - 15i) * 2 + 15i
= ( 4 + 30i)/ (4 + 225)
= (4 + 30i )/ 229
Hence; 2/ 2 - 15i
= 4/ 229 + 30i/ 229
Therefore, Letter Choice (D); is your answer 4/229 + 30i/229
Hope that helps!!!!
Answer:
ABCDEFG = 3211000
Step-by-step explanation:
A counts the number of zeroes, and there are 3 zeroes (E, F, G), so A = 3.B counts the number of ones, and there are 2 ones (C, D), so B = 2.C counts the number of twos, and there is 1 two (B), so C = 1.D counts the number of threes, and there is 1 three (A), so D = 1.There is no four, five, six in, so E, F, G are all zeroes.
