This is the first section

OpenStudy (solomonzelman):

these questions are based on something that I can't see. Lack of information.

OpenStudy (marissalovescats):

What do you mean?

OpenStudy (marissalovescats):

I forget how I would solve this: ln h = -1.2 + 1.4 (ln C) C=60

OpenStudy (solomonzelman):

I can't type more than a line, the post button is hiding from me

OpenStudy (solomonzelman):

ln h = -1.2 + 1.4 (ln C)

OpenStudy (solomonzelman):

ln h = -1.2 + 1.4 (ln 60)

OpenStudy (solomonzelman):

ln h = -1.2 + (ln 60^1.4)

OpenStudy (solomonzelman):

ln h - (ln 60^1.4)= -1.2 ln (h/ 60^1.4)= -1.2

OpenStudy (solomonzelman):

ln (h/ 60^1.4)= -1.2ln(e)

OpenStudy (solomonzelman):

ln (h/ 60^1.4)= ln(e^-1.2)

OpenStudy (solomonzelman):

h/ 60^1.4= ln e^-1.2 h= ln e^-1.2 times 60^1.4

OpenStudy (solomonzelman):

this is the exact answer

OpenStudy (solomonzelman):

h= ln e^-1.2 times 60^1.4 h=-1.2 ln e times 60^1.4

OpenStudy (solomonzelman):

h=-1.2 times 60^1.4

OpenStudy (solomonzelman):

h=-370.333

OpenStudy (marissalovescats):

The answer is supposed to be 93

OpenStudy (solomonzelman):

Going from ln (h/ 60^1.4)= ln(e^-1.2) I made a mistake.

OpenStudy (solomonzelman):

ln (h/ 60^1.4)= ln(e^-1.2) h/ 60^1.4= e^-1.2 h= e^-1.2 times 60^1.4

OpenStudy (solomonzelman):

yup

OpenStudy (solomonzelman):

sorry for the first mistake
