Question

When will the total rise in water level be equal to about half a meter ?

Answer 1

x = 312. 5 years.

Step-by-step explanation:

We know that the water level is rising at a rate of 1.6 mm per year and the water level is modeled by f = 1.6x where x is the number of years after 1880.

Now,

1 m = 1000 mm

therefore,

1/2 m = 500 mm

and so when we are making when the water level be half a meter, we are solving the equation

1.6x = 500

dividing both sides by 1.6 gives

x = 312.5 years

add the above to 1880 to get the year

1880 + 312. 5 = 2192.5

Hence in the year 2192. 5, the water level will be half a meter.
