Answer:
1. (2x^2+x-1)
Step-by-step explanation:
expanding (2x^2-1)^2. multiplying (x-2) (1-2x)
= 4x^2-4x+1. = x-2x^2-2+4x
= -2x^2+5x-2
(4x^2-4x+1-2x^2+5x-2)
=2x^2+x-1
Answer:
Step-by-step explanation:
3/4x + -3
Answer:

Step-by-step explanation:
Given:

where,
T = total amount of waste
P = 50, the initial rate
k = 0.04
t = time

now we need to solve this integral!




when any number has a power of negative infinity it is 0. because:
, like something being divided by a very large number!


this is the total amount of waste
