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:
the answer is B
Step-by-step explanation:
6w + 5 - 3w + 7
<h3>i) collect like terms</h3>
= 6w - 3w + 5 + 7
= 3w + 5 + 7
<h3>ii) add the numbers</h3>
= 3 w + 5 + 7
= 3w + 12
Answer:
(2x + 5) (x + 2)
Step-by-step explanation:
(2x + 5) (x + 2)
2x² + 4x + 5x + 10
2x² + 9x + 10
Ah, i’ve seen this one before. this answer is no no idea why you gotta get a chance and i’m you to go pick it out to get your stuff back on your car wash the car and stuff and you get your hair and get it done and you get a little more comfortable with your car and you get a hold on you like that one or a little bit more and stuff and like move you
