Answer:
3. f = gh
4. r = 1/s³
5. y = x[tex]\sqrt{z}[/tex]
6. m = n²/p
7. Inverse variation, s is constant
8. Direct Variation, x is constant
9. joint variation, q and r are both constants
10. Direct variation, r is constant
11. Joint variation, r and h are both constants
12. Inverse variation, x is constant
13. y = kx
17.5 = 21k
k = 21/17.5
y= (21/17.5)*39
y = 46.8
14.
m = kn
209 = 22k
k = 209/22
361 = (209/22)n
n = (361*22)/209
n = 38
