The depth of the ocean crust can be approximated by the equation: d=2500+350*t^1/2, where d=depth in meters, and t=age in millions of years

OpenStudy (anonymous):

can anyone help with this ???

OpenStudy (anonymous):

what is the question lol

The depth of the ocean crust can be approximated by the equation: d=2500+350*t^1/2, where d=depth in meters, and t=age in millions of years. How old would the crust be if it were 5000 m deep? How deep would the crust be if it were new (zero years?

lol do u get it??

OpenStudy (anonymous):

yeah sorry i was away, i will answer you in 5 minutes

OpenStudy (anonymous):

ok thankss

OpenStudy (anonymous):

\[t=((d-2500)/350)^2\] \[t \approx 51\] MegaYears

OpenStudy (anonymous):

step by step ?

OpenStudy (anonymous):

1. substract 2500 from both sides of the equation 2. devide 350 on both sides of the equation 3. square both sides of the equation

OpenStudy (anonymous):

4. plug in your value of t = 5000 5. get an approximative answer of 51 MY

ok got it thank you.

you are welcome.
