Answer:
{x,y,z} = {1,-1,-2}
Step-by-step explanation:
Looks like the integrand is
The denominator is factorized as
Then we want to find constants such that
We can use the cover-up method to easily find and :
This would be -19x because of the minus it makes the 25 a negative while the 6 is a positive and a negative + positive = negative in this case
The equation for interest also works for depreciation
the price drops by 11%
or the price of the machine next year would be 89% of this year
the initial price is 60,000
the amount of years is 5
and the percentage of next year is 89
the full equation would be
60,000(0.89)^5
the price of the machine after five years is <span>33504.356694 (not rounded)
