ll.find the constant variation of the following variation

21. E is inversely proportional to z and z = 4 when E = 6.

22. a varies directly as n. if n = 12 then a = 9.

23. T varies as the square root of Land L = 82 then T = 10.

24. m varies jointly as I and n, m = 13 when I = 39 and n = 3.

25. s varies jointly as square oft and square of r, as s = 72 and t and requals to 2 and 3 respectively.

Answer:

21. 24

22. 3/4

23. 82 'yan or typo? basta kung 81, 10/9 tas kung 82 talaga (5sqr. root of 82)/41

24. 1/9

25. 4

Step-by-step explanation:

21. E=k/z

22. a=kn

23. t=k(sqr root L)

24. m=kln

25. s=ktr²
