Water is being pumped to empty a swimming pool.

IceJOKER [234]

To empty the pool, you need to lower the water level by 150cm. since you can only lower it by 30cm every 2 hours (also same as 15 cm per hour), that means it will take you 10 hours.

150cm*(2 hours)/(30cm) = 150*(1/15) = 150/15 = 10.

6 a.m. + 10 hours = 4 p.m.

So the answer is C.) 4 p.m.

Im so confused pls help

Answer:

(d) f(x) = log₆(x)

Step-by-step explanation:

If we use y in place of f(x), we see that ...

x = 6^y

Taking logs of both sides, we get ...

log(x) = y·log(6)

y = log(x)/log(6)

y = log₆(x) . . . . . . . using the change of base formula

f(x) = log₆(x)

_____

Or you can get there more directly using the relation between logs and exponentials:

$\displaystyle a = b^c\ \leftrightarrow\ c=\log_b(a)$
