Answer:
xy=302,400
Step-by-step explanation:
i just did the problem right now on edge and that's what i got
hope this helps and that I'm not too late
Maybe if i add 10 + 30 is = 40 this is my answer
Answer:
Option A. ![f(x)=86[1.04]^{x}](https://tex.z-dn.net/?f=f%28x%29%3D86%5B1.04%5D%5E%7Bx%7D)
; grows approximately at a rate of 0.4% daily
Step-by-step explanation:
we have
where
f(x) the number of weeds in the garden
x ----> the number of weeks
Calculate how quickly the weeds grow each day
Remember that a week is equal to seven days
so
Using the law of exponents
b^(x/a) = b^(x*(1/a)) = (b^(1/a))^x
so
![f(x)=86[(1.29)^{\frac{1}{7}}]^{x}](https://tex.z-dn.net/?f=f%28x%29%3D86%5B%281.29%29%5E%7B%5Cfrac%7B1%7D%7B7%7D%7D%5D%5E%7Bx%7D)
therefore
The rate is approximately
1.04=1+r
r=1.04-1=0.04=4% daily
Thats the same thing as 0.3 x 10
when mulitplying by 10, 100, 1000, etc.
what i do is i move the decimal place over how many zeros there are so there is one zero and that means you need to move the decimal place over one space to the right so the answer is
3
Answer:
3) 87.9 or 1) 12.5
Step-by-step explanation:
they did multiply then subtract
