The Deep Sea Explorer
A marine biologist is preparing a robotic submarine for a mission to the ocean floor.
To calibrate the mission parameters, she must decode two values from the submarine’s manual that are written in expanded exponential form.
Part A: The Depth Goal
The target depth for the mission is programmed as:
\( (9 \times 10^{4}) + (5 \times 10^{3}) + (5 \times 10^{2}) + (3 \times 10^{1}) + (3 \times 10^{0}) \)
What is the target depth in meters? \(m\)
Part B: The Salinity Sensor
The sensitivity of the salt-water sensor must be set to:
\((0 \times 10^0) + (3 \times 10^{-1}) + (5 \times 10^{-2}) + (2 \times 10^{-3})\)
What is the sensor sensitivity in standard decimal form?
