Solve for k. a/b=b/a+1/k

Mathematics
1 answer:
ArbitrLikvidat [17]4 years ago

Answer:

k = ab/ ( a^2 - b^2)

Step-by-step explanation:

a/b=b/a+1/k

Multiply each side by abk to get rid of the fractions

abk *a/b=abk(b/a+1/k)

a^2k = b^2k + ab

Subtract b^2k from each side

a^2k - b^2k = b^2k - b^2k + ab

a^2 k - b^2 k = ab

Factor out k

k( a^2 - b^2) = ab

Divide each side by ( a^2 - b^2)

k( a^2 - b^2)/  ( a^2 - b^2) = ab/ ( a^2 - b^2)

k = ab/ ( a^2 - b^2)

1) Option C is correct

2) Option B is correct

Step-by-step explanation:

Question no 1:

We need to find the constant of proportionality

The constant of proportionality can be found by using the formula y/x = k, where k is the constant of proportionality.

Finding k:

x = Hot pepper corn

y = chedder corn

So, y/x = 10/4 = 2.5

y/x = 20/8 = 2.5

y/x= 30/12= 2.5

So, Constant of proportionality is k = 2.5

Hence Option C is correct.

Question No 2

Every female rabbit has 5 baby rabbits. We need to find ratio of baby rabbits to female rabbits.

Baby rabbits = 5

female rabbits = 1

Ratio of baby rabbits to female rabbits: 5: 1 or 5/1 = 5

So, ratio of baby rabbits to female rabbits is 5

Option B is correct.
