High and low frequency a porpoise can hear are 1.5 x10^5 and 7.5 x 10^1. which is a reasonable estimate of the quotient of the highest and lowest audible for the porpoise?
a. 10,000,000 and 100,000,000
b. 1000 and 10,000
c. 100,000 and 1,000,000
d. 10,000 and 100,000

The orders of magnitude of the highest and lowest frequencies are and . This means that their ratio is

Since the highest frequency has the lesser coefficient, the ratio will be less than 10.000. So, an estimate can be "between 1.000 and 10.000"

For the record, the answer is

which is indeed between 1.000 and 10.000.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
