Consider the equation Cost = 4.3 + 6.89 *log(length). How should the length be increased such that the cost increases by 6.89 units? (e ≈ 2.718)

Length increased by the multiplying of e

Step-by-step explanation:

From the question we are told that:

Therefore cost increase by 6.89 is given as

Since

Therefore

Since

Therefore

Therefore

Length increased by the multiplying of e

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
