The depth of the ocean is sometimes measured in fathoms (1 fathom = 6 feet). Distance on the surface of the ocean is sometimes measured in nautical miles (1 nautical mile = 6076 feet). The water beneath a surface rectangle 1.20 nautical miles by 3.70 nautical miles has a depth of 18.0 fathoms. Find the volume of water (in cubic meters) beneath this rectangle. Number i Units

(a) The volume V of a growing spherical cell is V = ³, where the radius is measured in micrometers (1 μm = 10-6m). Find the average rate of change of V with respect to r when r changes from 6 to each of the following. (Round your answers to one decimal place.) (i) 6 to 9 μm # Tab (ii) 6 to 7 μm aps Lock Esc Submit Answer (iii) 6 to 6.1 um (b) Find the instantaneous rate of change of V with respect to r when r = 6 μm.

I need help with this question. I also don't know what the units should be for the answer. Is it m/s^2 or is it kg m/s^2

Each of the following equations was given by a student during an examination 1/2 mv^2=1/2 mv_0^2+√mgh v=v_0+at^2 ma=v^2        Do a dimensional analysis of each equation and explain why the equation can’t be correct.  (Hint:  Determine the dimensions on each side of the equation and compare them.)

Can you please write this in interval notation and explain how you got these answers?

Make sure all quantities are expressed in standard units before calculating anything. Tank what my teacher added. Thank you :)

The base of a pyramid covers an area of 12.8 acres (1 acre = 43,560 ft²) and has a height of 471 ft. If the volume of a pyramid is given by the expression V = bh/3, where b is the area of the base and h is the height, find the volume of this pyramid in cubic meters. m³ ⒸSylvain Grandadam/Photo Researchers, Inc.

A) A pyramid has a height of 488 ft and its base covers an area of 10.0 acres. The volume of a pyramid is given by the expression: V=1/3Bh, where B is the area of the base and h is the height. Find the volume of the pyramid in cubic meters. (1 acre = 43,560ft^2). B) What If? If the height of the pyramid were increased to 525 ft and the height to base area ratio of the pyramid were kept constant, by what percentage would the volume of the pyramid increase?
