9. 2.86600.... that is all i know so far
A=Pe^(rt)
P = 800g
t = 8 years
A = 450g
r = This is what we will try and find to start with
450=800e^(r*8)
After running the math through a calculator, we end with r = -0.07192
Now we just re-input this information into our equation: A=800e^(-0.07192*16)
A=800e^(1.15072)
Now we will re-write the equation using the negative exponent rule:
A = 800 1/e^1.15072
Combine right side:
A = 800/e^1.15072
Then do the math:
A = 253.12709836......
That will give us A = 253 (rounded to the whole number)
I hope this helps! :)
Answer:
x = xi + delta x
-2+1 = -1
y = yi + delta y
-5+3 = -2
(-1,-2)
Step-by-step explanation:
The answer is 404 visitors per day, Because 3/1212=404
<span>4+6(7x+7)
= 4 + 42x + 42
= 42x + 46
