What is the value of a in the polynomial

Mathematics
1 answer:
Alexandra [31]3 years ago
5 0

Answer: a= 16

Step-by-step explanation:

We have the following expression:

(y-4)(y^2 +4y +16)

To find the value of the coefficient "a" you must use the distributive property to multiply the expression:

(y-4)(y^2 +4y +16)

until you transform it to the form:

y^3 +4y^2 +ay -4y^2 -ay-64

Then we have

(y-4)(y^2 +4y +16)\\\\(y^3 +4y^2 +16y -4y^2 -16y-64)\\\\

Therefore the value of a in the polynomial is 16

What are the coordinates of the inflection point on the graph of y=(x+1)arctanx
Dennis_Churaev [7]

Inflection point is the point where the second derivative of a graph is zero.

y = (x+1)arctan xy' = (x+1)(arctan x)' + (1)arctan xy' = (x+1)/(x^2+1) + arctan xy'' = (x+1)(1/(1+x^2))' + 1/(1+x^2) + 1/(1+x^2)y'' = (x+1)(-1/(1+x^2)^2)(2x)+2/(1+x^2)y'' = ((x+1)(-2x)+1+x^2)/(1+x^2)^2y'' = (-2x^2-2x+2+2x^2)/(1+x^2)^2y'' = (-2x+2)/(1+x^2)^2

Solving for point of inflection: y'' = 00 = (-2x+2)/(1+x^2)^20 = -2x+2x = 1y(1) = (1+1)arctan(1) = 2 * pi/4 = pi/2

Therefore, E(1, pi/2).
