5 0

Answer:

the answer is option B

Step-by-step explanation:

To find dy/dx the equation here is

first multipled by derivative of second + second multipled by derivative of first

y = x*sinx

dy/dx = x * derivative of sinx + sinx * derivative of x

derivative of x with respect to x is 1

derivative of sinx with respect to x is cosx

therefore

dy/dx = x * cosx + sinx * 1

= x * cosx + sinx

What is the point-slope equation of a line with slope -5 that contains the point (6,3)
Luden [163]

Answer:

y-3=-5(x-6)

Step-by-step explanation:

we know that

The equation of the line into point-slope form is equal to

y-y1=m(x-x1)

we have

m=-5

(x1,y1)=(6,3)

substitute

y-3=-5(x-6) ----> equation of the line into point-slope form
