Answer:
k = 18
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 3 when x = 6, that is
3 = 
( multiply both sides by 6 )
18 = k
The constant of variation is k = 18
Answer:
because one i one is higher than the other, if you look at it
Answer: Robert ran faster than Jocab
Step-by-step explanation:
Convert the improper fraction to a proper fraction
Jocab = 5miles in 1 1/2 hours, therefore, 1 1/2 hours = 3/2 hours, to convert to minute will be 3/2 x 60 = 90 minutes
Robert = 3 miles in 3/4 hours = 45 minutes
If Robert runs 3 miles in 45 minutes, by the end of 90minutes, Robert would have covered 6miles, while Jocab covered 5miles in 90 minutes, therefore, Robert ran faster than Jocab.
Answer:
Step-by-step explanation:
I really hope that solving a few trig questions can forestall death. That would be a really easy way to get rid of the C 19 restrictions and a myriad other diseases. BETTER LIFE THROUGH MATH will be our motto.
11) tan45 = x/13 x = 13
cos45 = 13/y y = 13√2
12) sin30 = 4/x x = 8
tan30 = 4/y y = 4√3
13) sin60 = 21/x x = 21(2/√3) = 42/√3
y = xcos60 = (42/√3)(1/2) = 21/√3
14) cos45 = x/22 x = 22/√2
sin45 = y/22 y = 22/√2
15) Height = 24sin30 = 12
cos 45 = 12/x x = 12/√2
tan45 = y/12 y = 12
cos30 = z/24 z = 24(√(3)/2) = 12/√3
