If this condition is false, the current cell should display the result of multiplying cell B11 (hours booked) by cell B8 (hourly fee). Use a relative reference to cell B11 and an absolute reference to cell B8 so that the formula can be copied to other cells.
If you are an information security professional within your company, you will be asked to understand the threats, vulnerabilities, and risks that may impact the company. If your boss asks you which is more important to focus on, threats or vulnerabilities, how would you respond?
Justify your response.

There are two values depending on the point.
##{dx}/{dt}={(-8 ” at ” (3,4)),(8 ” at “(-3,4)):}##
Let us look at some details.
First, let us find the values of ##x##.
By plugging in ##y=4## into ##x^2+y^2=25##,
##x^2+16=25 Rightarrow x^2=9 Rightarrow x=pm3##
Now, let us find some derivatives.
By differentiating with respect to ##t##,
##d/{dt}(x^2+y^2)=d/{dt}(25) Rightarrow 2x{dx}/{dt}+2y{dy}/{dt}=0##
by dividing by ##2x##,
##Rightarrow {dx}/{dx}+y/x{dy}/{dt}=0##
by subtracting ##y/x{dy}/{dt}##,
##Rightarrow {dx}/{dt}=-y/x{dy}/{dt}##
Since ##y=4##, ##x=pm3##, and ##{dy}/{dt}=6##,
##{dx}/{dt}=-{4}/{pm3}(6)=pm8##
