...
Step-by-step explanation:
remeber that for every angle they give you, you need to subtract 90 from it to get the answer.
Number 2 is correct. For number 3, the mean is 9 and the mean absolute deviation is 1.33.
Answer:
T = 0.34r³
Step-by-step explanation:
Given that T is directly proportional to r³ then the equation relating them is
T = kr³ ← k is the constant of variation
To find k use the condition T = 21.76 when r = 4 , then
21.76 = k × 4³ = 64k ( divide both sides by 64 )
0.34 = k
T= 0.34r³ ← equation of variation
