Answer:
Step-by-step explanation:
Given differential equation is
y"+y'-2y = 1
Hence, the characteristics is
=> D = -2, 1
The general equation of the given differential equation is
Let's consider that
g(t) = 1
Wronskian can be given by,
W = y_1(t)y'_2(t) - y_2(t)y'_1(t)
Now, the particular integral can be given by
Now,
Hence, the complete solution of the given differential equation is
3 boxes of paper cost 3*21.99=65.97, 2 toner cartridges cost 2*52.90=105.8.
Given that there's 20% off for all office supplies, then 3 boxes of paper cost 3*$21.99*0.8=$52.78,
2 toner cartridges cost 2*$52.90*0.8=$84.64, the price of folder is $0.99*0.8=$0.792.
So, after buying these things given that there's 20% off for all office supplies, he will have only
$175-$52.78—$84.64= $37.58.
As 37.58/0.792=47.45, hence he can buy only 47 folders
Answer is 47
Answer: y = x^{2} - 16
Step-by-step explanation: Work backwards to find the factors from the root, then multiply the factors together.
