Year Net Profit
1 $14,250.00
2 $15,390.00
3 $16,621.20
4 $17,950.902

We need to get the increase of the net profit of the current year from the previous year.

Percentage increase = (Current year - Previous Year)/ Previous Year * 100%

Year 2: (15,390 - 14, 250) / 14,250 * 100% = 0.08 * 100% = 8%
Year 3: (16,621.20 - 15,390) / 15,390 * 100% = 0.08 * 100% = 8%
Year 4: (17,950.90 - 16,621.20) / 16,621.20 * 100% = 0.08 * 100% = 8%

Every year the net income increases by 8%. So, the net income in Year 5 will be:

17,950.90 x 1.08 = 19,386.97 Choice D.

SCORPION-xisa [38]

Answer:

Greater.

Step-by-step explanation:

The in the function $f(x)=2x^2+5\sqrt{x-2}$ , the square root term $\sqrt{x-2}$ has to give a real number if $f(x)$ is to be real. This can only happen if $x\geq 2$ because if $x$ then $\sqrt{x-2}$ will give a complex number and therefore $f(x)$ will not be real.
