Answer:
a2=b2+c2-2bc cos a
Step-by-step explanation:
When a line is perpendicular, the slope is the negative reciprocal. Therefore, since the slope is 4, the slope of a line perpendicular is -1/4
Answer:
m = 10
Step-by-step explanation:
Given w is inversely proportional to m then the equation relating them is
w =
← k is the constant of variation
To find k use the condition w = 8, m = 25 , then
8 =
( multiply both sides by 25 )
200 = k
w =
← equation of variation
When w = 20 , then
20 =
( multiply both sides by m )
20m = 200 ( divide both sides by 20 )
m = 10
