Gilbert is -17 meters under sea level every second(s) he gains 0.5 meters after how many seconds is he at sea level?

He is at sea level after 34 seconds

Step-by-step explanation:

The height at sea level is given as 0 meters

So the change in height would be;

0- (-17) = 17 meters

There is a gain of 0.5 meters in 1 second

So, the time taken for it to gain 17 meters will be 17/0.5 = 34 seconds

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
