Instantaneous rate of change Given the equation A=sqrt3/4 (5x-1)^2, what is the instantaneous rate of change of A with respect to x at x=1?

Expert Answers

An illustration of the letter 'A' in a speech bubbles

`A=[sqrt(3)]/4*(5x-1)^2=>`

`A'=[sqrt(3)]/4*2*(5x-1)*5=>`

`A'=[5sqrt(3)]/2*(5x-1)`

`A'(1)=[5sqrt(3)]/2*(5-1)=>`

` ` `A'(1)=10sqrt(3)`
