Answer:
405
Step-by-step explanation:
r sequence= 5,15,45,135
d sequence:=10,30,90,270
r ratio is the Radio
d ratio is de Diameter
2*r=d
5*2=10, 15*2=30, 45*2=90, 135*2=270
to complete the sequence:
r+d= next r and continue
5+10=15
15+30=45
45+90=135
135+270=405
The answers are:
(2, -1)
(0, 3)
(-1, 5)
You just plug in the x values into the equation, solve, and see if you end up with the corresponding y value.

Answer:
B. A water wheel in a dry river
Step-by-step explanation:
Work is said to be done when a force moves a body or an object through a certain distance in the direction of the force. Thus for work to be done, force and distance are required.
i.e Work done = Force x distance
It is measured in Joules.
Also, the work done by an object could be a measured of potential energy.
So that,
Work done = potential energy = mass x gravitational force x height
Considering the collage in the question, since the water wheel is in a dry river no work is done. Water wheel is a device that functions through the flow of water body, thus causing its rotation.
