Answer:
see explanation
Step-by-step explanation:
given that V is directly proportional to u and inversely proportional to f , then the equation relating them is
V = 
← k is the constant of proportion
(a)
to find k use the condition when u = 1 and f = 3 , V = 
, then
= 
( cross- multiply )
6k = 3 ( divide both sides by 6 )
k = 
= 
V = 
← equation of proportion
(b)
when f = 4 and V = 1 
= 
, then
= 
= 
( cross- multiply )
4u = 40 ( divide both sides by 4 )
u = 10
Answer:
x=3 and y=5 passes through(3,5)
x=2 and x=3 is perpendicular to y=3
so anwer is x=3
Answer:
x = 20°
Step-by-step explanation:
So when I learned it we called it the exterior angle theorem not the angle sum theorem but here goes.
Since exterior angle = 110 Degrees,
--> The Inner 2 angles's sum = 110 Degrees
so, 70 + 2x = 110
=> 2x = 40
x = 20
x = 20°
