Answer:
r = 6
Step-by-step explanation:
Given that M is directly proportional to r³ then the equation relating them is
M = kr³ ← k is the constant of proportionality
To find k use the condition r = 4 when M = 160
k = =
= 2.5, so
M = 2.5r³ ← equation of proportionality
When M = 540, then
540 = 2.5 r³ ( divide both sides by 2.5 )
216 = r³ ( take the cube root of both sides )
r = = 6
Answer:
Step-by-step explanation:
ok so I'm going to try to show it the best c an
m = slope
the equation you use is
m
so when using that formula with the cords, you get
and then subtract everything and you'll get
