<span>For exponential decrease use the formula P(1 - r)^t
p: initial amount
r: rate of change or percent of decrease (be sure to put in decimal form or you wont get the right answer)
t: amount of time (in years)
1,000,000 (1-0.042)^15 =
$525,391.01
(also make sure to use pemdas or order of operations when solving) hope this helps :)</span>
Answer: i havent done this in a long long time but i think it may be
15n-0.10
Step-by-step explanation:
At the standard 0.05 value, this is not significant, however at a 0.01 level, it would be significant
The rates are equivalent because both of them do 30 jumping jacks a minute.
<span>This is how to solve for log expressions.
First, do the arithmetic such that all that can be solved is in the other side, besides log.
There are different properties of log to help you solve log expressions.
log4x − 616 = 4
</span><span>log4x = 620
</span>Change how it is written to solve for x.
x^620 = 4
This makes no sense so we try again.
Or, this could be solved differently.
log 4x-6 16 = 4
(4x-6) ^4 = 16
256x - 1296 = 16
x = 5.125
Final answer: x = 5
