Answer:
choices A and F are part of Leo's system of equations
Step-by-step explanation:
The formula for the amount in an account compounded annually is ...
A = P(1 +r)^t
For the given amounts and variables, that is ...
y = 500(1.025)^x . . . . matches F
__
The formula for the amount in an account compounded continuously is ...
A = P·e^(rt)
With given values, this is ...
y = 400e^(0.02x) . . . . matches A
Answer:
i believe it's 2 per mile could be wrong tho :)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Begin by dividing by 5
2x + 4 = 3
Is this written as 2^(x + 4) = 3? I think it is.
Take the log of both sides
log 2^(x + 4) = log(3)
(x + 4) * log(2) = log 3
log 2 = 0.30103
log 3 = 0.47712
(x + 4) = log2 / log3
x + 4 = 0.63093 Add 4 to both sides
x = -3.369 Rounded to the nearest thousandth
====================
If you mean the question exactly as it is written (the 4 is not part of the power)
5(2^x + 4) = 15
2^x + 4 = 3
2^x = 3 - 4
2^x = - 1
This can't be done 2 to any power should be >0.
if x>0 then this will give an ever increasing number
if xK0 then this will give an ever decreasing answer but still greater than 0.
No value will make 2^x go to something minus.
If I have misread this in some way, leave a note and I will get back to you.
1303/12.8 is the answer for that one which it should land in the middle of the line!
