Answer:
y = 650·0.922^t
Step-by-step explanation:
At the end of each year, 92.2% of the amount at the beginning of the year remains. That is, the beginning amount is multiplied by 0.922. The exponent t in 0.922^t tells how many times (years) that multiplication has taken place. At the end of t years, the amount remaining in milligrams (y) is ...
y = 650·0.922^t
Answer:
I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).
Step-by-step explanation:
So, my answer was f(20) = 64(1/2)^19
f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.
Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19
I hope this helps!
Answer:
x = 51/6 or 17/2
<u>Step-by-step explanation:</u>
9( x-3) = 3 (x + 8)
Distribute
9x - 27 = 3x + 24
Add 27 to both sides
9x = 3x + 51
Subtract 3x from both sides
6x = 51
Divide both sides by 6
x = 51/6 or 17/2
area = S^2
so 20.25 = S^2
take square root of 20.25 for length of side
square root of 20.25 = 4.5 inches
