Last derivatives based problem. would be appreciated.

The derivative of is defined by the limit,

In this case, , so the derivative would be

Simplifying the numerator gives

The numerator and denominator share a common factor of , which we can cancel because means that we're considering so that :

Then as , we're left with the derivative

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
