Find an equation of the tangent line to the curve at the given point. y = 7x + 9 cos(x), p = (0, 9)

Alright, lets get started.

We have given a curve y, and a point P.



The derivative of the curve is the slope of the tangent line.

We will find the derivative of the given function.







Putting the value as x = 0 because P (0,9)



As sin 0 = 0





The equation of tangent will be : where m is slope



Putting the value of (x,y) as (0,9), we could find the value of c



c = 9

Hence the equation of tangent will be :



Answer

Hope it will help :)

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
