Answer:
R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]
Step-by-step explanation:
Squaring both sides of equation:
I^2 = (ER)^2/(R^2 + (WL)^2)
<=>(ER)^2 = (I^2)*(R^2 + (WL)^2)
<=>(ER)^2 - (IR)^2 = (IWL)^2
<=> R^2(E^2 - I^2) = (IWL)^2
<=> R^2 = (IWL)^2/(E^2 - I^2)
<=> R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]
Hope this helps!
Answer:
maya - 6 min per puzzle
amy - 7 min per puzzle
maya would finish first since her unit rate is smaller. for example, it takes maya 30 for 5 but it would take 35 for 5.
Step-by-step explanation:
Your answer will be D and E
The formula for the area of a parallelogram is
A=b*h where b=base and h=height
if the base were to increase by 3times and the height were to increase by 2 times then
6A=b*h
The area of the parallelogram would be 6 times larger
So if the original area was 47units², then the new area would be
47*6=282units²
Answer=282units²
