Question

y varies jointly as the square x and the inverse of z. When y = 24 and x = 4, z = 6. Find the constant of variation and determine the value for x when y = 15 and z = 15.

Answer 1

???????????? "vary jointly" ?????????

????????? "invers av z" ???????

yu kant du invers av a number, yu kan oenlee invers a op

me spekt huever rote that thank av invers av multipli & thun want 1/z

offhand me wood ges yu hav y=a*x^2 +b/z

but that hav 2 dont-nos & yu oenlee suppli 1 point

so maebee sumwon want y=a*(x*x=1/z)

The 1 pont yu giv...x=4, z=6 & y=24...x*2=16 & 1/6=0.1666666666666...

so 24=a*(16.16666666666...)

wich giv a=24/16.166666

a=1.440000000001

tri that with y=15 & z=15 & see wot cha get
