Answer:

68.7

Step-by-step explanation:

We need only estimate (approximate) the value of f(x) at x = 5:

f(x)=6.87(2.5)(x – 1)   →   f(5)=6.87(2.5)(5 – 1).

Note that 2.5(4) = 10, so now we have (exactly) f(5)=6.87(10), which, in turn, is

equal to 68.7.

Lars works as a nurse and a lumberjack. He wants to work for at most 666 days this week, and he wants to earn more than \$950$95
Nesterboy [21]

Answer:

Lars works for the expected number of days but doesn't earn the expected amount of money.

Step-by-step explanation:

Let's check whether Lars works for the expected number of days this week by working as a nurse for 2 days and working as a lumberjack for 4 days. To do this, we substitute N=2 and L=4 into the first inequality:

N+L≤6

2+4≤6

6≤6

The true inequality shows that Lars works for the expected number of days this week by working as a nurse for 2 days and working as a lumberjack for 4 days.

Now let's check whether Lars earns the expected amount of money by working as a nurse for 2 days and working as a lumberjack for 4 days.

To do this, we substitute N=2 and L=4 into the second inequality.

216N+112L>950

216(2)+112(4) > 950

880 >950

​  

The false inequality shows that Lars doesn't earn the expected amount of money by working as a nurse for 2 days and working as a lumberjack for 4 days.

Lars works for the expected number of days but doesn't earn the expected amount of money.
