An empty bathtub is filled at a constant rate of 8 gallons per minute. The bathtub will hold 36 gallons of water when full. The volume, V, of water in the bathtub is a function of t, the time in minutes. Which is the best description for the domain of the function V?

i think this could be a possible answer (1 / 84) -1

good luck! : d

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
