Answer:
y = 15·2.1599^x
Step-by-step explanation:
We know that the number changed by the ratio 1523/15 = 101.5333... in 6 days, so the daily multiplier is the 6th root of this:
b = 101.5333...^(1/6) = 2.1599 . . . rounded to 4 dp
Of course, the coefficient 'a' in the equation is the initial number, 15.
Your exponential equation is ...
y = 15·2.1599^x
a = 15
b = 2.1599
Answer:
C
Step-by-step explanation:
Remark
You must do the changes in order. Add 1 then multiply by 2
- First entry: 6
- Add 1: 6 + 1 = 7
- Multiply by 2 = 2*7 = 14
- Add 1: 14 + 1 = 15
- Multiply by 2: 15 * 2 = 30
Answer: 7 14 15 30
3 + 2k
This is because multiplying by 1/5 is like dividing each term by 5
23 can round to 20 and 21 can also round to 20 so all u do is 20x20=400 so 400 is your estimated answer
