3)

Step-by-step explanation:

1)

This integral can be solved easily by using algebraic substitutions:

,

Then, the integral can rewritten as follows:

Where is the integration constant.

2) Let be , then we obtain the expression by the definition of the derivative for the inverse hyperbolic cosine and the chain rule:

3)

This integral can be solved by the following trigonometric substitutions:

Where is the integration constant.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
