Alex787 [66]

Answer with explanation:

Presume that, initial water level to be, 0 mm, at a time t=0.

And water level is rising at the rate of 1.8 \frac{\text{mm}}{\text{year}}.

 After 6.2 years level of water will be =1.8 × 6.2

                                                           =11.16 mm

→Averge, that is increase in water level after 6.2 years is given by

                     =\frac{W_{2}-W_{1}}{t_{2}-t_{1}}\\\\=\frac{11.16-0}{6.2-0}\\\\=\frac{11.16}{6.2}\\\\=1.8 \frac{\text{mm}}{\text{year}}

→→Rate of Depreciating of water level is given by = Negative of Increase of water level=-1.8 \frac{\text{mm}}{\text{year}}

Can someone help me with this problem?
pashok25 [27]
No, it is not a solution.

Let's plug 5 into the equation where p is.

10(5) - 2 > 97

50 - 2 > 97

48 > 97

This is false, 48 is less than 97.
