Tides in a specific location can be approximated using the periodic function shown on the graph. what is the interpretation of the amplitude in this application? a. the time between high tides b. the time between high tide and low tide c. the sum of the heights at high tide and low tide d. the difference between the height at high tide and low tide

D

Step-by-step explanation:

Amplitude will never measure time(because time is never on the y-axis) this eliminates A and B.

C is incorrect because that is the displacement.

D is the answer because it will give you the individual height of high tide and low tide using the amplitude measured over a period of time.

a) what number, when added to negative four, is equal to negative five?

step-by-step explanation:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
