For this case we have the following function:

f (x) = x ^ 4 + 2x ^ 2-1

What we must do is evaluate the value of x = 3 in the given function.

We have then:

f (3) = (3) ^ 4 + 2 (3) ^ 2-1

Then, Rewriting the function we have:

f (3) = (3) ^ 4 + 2 (3) ^ 2-1

f (3) = 81 + 18-1

f (3) = 98

Answer:

The value of the function evaluated for x = 3 is given by:

f (3) = 98

Bob and James are finishing the roof of a house. Working alone, Bob can shingle the roof in 14 hours. James can shingle the same
Snowcat [4.5K]

we know that Bob can do the whole job in 14 hours, how much of the work has he done in 1 hour only?  well since he can do the whole lot in 14 hours in 1 hour he has only done 1/14 th of the job.

we know that James can do it in 18 hours, a bit slower, so in 1 hour he has done only 1/18 th of the job.

let's say it takes both of them working together say "t" hours, so in 1 hour Bob has done (1/14) of the work whilst James has done (1/18) of the work, the whole work being t/t or 1 whole, so for just one hour that'd 1/t done by both Bob and James.

\bf \stackrel{Bob}{\cfrac{1}{14}}~~+~~\stackrel{James}{\cfrac{1}{18}}~~=~~\stackrel{total~for~1~hour}{\cfrac{1}{t}} \\\\\\ \stackrel{\textit{using an LCD of 126}}{\cfrac{9+7}{126}=\cfrac{1}{t}}\implies \cfrac{16}{126}=\cfrac{1}{t}\implies 16t=126\implies t=\cfrac{126}{16} \\\\\\ \stackrel{\textit{7 hrs, 52 minutes and 30 seconds}}{t=\cfrac{63}{8}\implies t=7\frac{7}{8}}\implies \stackrel{\textit{rounded up}}{t=7.88}

e-lub [12.9K]

Usually, the more often it's compounded, the better. That's assuming that the percent is equal through all comparisons, however.
