Amarine biologist is measuring the temperature of a lake at 6 equally spaced depths. she makes her measurements at a point where the lake is 33.6 feet deep. what signed number represents the distantance and direction of the first measurement from the lake's surface?

-5.6 ft

Step-by-step explanation:

Since we are measuring depths this is regularly represented with negative numbers. If the biologist is performing the tests at a point of 33.6 ft depth (-33.6 ft) the first measurement will occur at -33.6/6= -5.6 ft

The following measurements will occur at -11.2, -16.8 ft, -22.4 ft, -28 ft and -33.6 ft

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
