The solar energy falling on the ocean is 1.7 x 10^6 kJ m^-2year^-1 and the phytoplankton are able to use 18 754 kJm^-2year^-1 of this. i. Calculate the percentage of the Sun’s energy that is used by phytoplankton. Show your working.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
