Question

Let R=qs4 , when s=8 , R=16. When s=10,R is equal to

Answer 1

R = qs4
When s = 8, R = 16 therefore;
16 = q(8 * 4) = 32q
q = 16 / 32 = 0.5

When s = 10,
R = qs4 but q = 0.5 therefore
R = 0.5 * 10 * 4 = 20

Answer 2

R = 39.0625

Explanation:

Given:
`R = qs^4`

We have to find q, when s = 8 and R = 16

Now plugin these value in the above equation, we get

16 = q.
`8^(4)`

16 = q.4096

q =
`(16)/(4096)`

q = 0.00390625

Now plug in q = 0.00390625 and s = 10 in above given formula and find the value of R.

R = 0.00390625*
`10^(4)`

R = 0.00390625*10000

R = 39.0625
