The slope of the normal curve y=3x^2-5x is at the point (0,0)
Rufina [12.5K]

Answer:

\frac{1}{5}

Step-by-step explanation:

Consider the curve y=3x^2-5x

Differentiate with respect to x

\frac{dy}{dx} =3(2x)-5=6x-5

( Use \frac{d}{dx}(x^n)=nx^{n-1} )

Slope of normal curve is given by \frac{-1}{\frac{dy}{dx} }

Slope of normal curve = \frac{-1}{6x-5}

To find slope of normal curve at point (0,0) ,put x=0 in \frac{-1}{6x-5}

Slope of normal curve at point (0,0) = \frac{-1}{6(0)-5} =\frac{-1}{-5}=\frac{1}{5}

Debora [2.8K]

Answer:

1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.

Step-by-step explanation:

Given: Jamal Sliced aright circular cylinder into congruent pieces.

To find: Shape of Two-Dimensional plane section obtained after slicing.

We get congruent pieces only when we slice the cylinder parallel to its base at equal heights.

By doing this we get small pieces of cylinders of equal height and equal radius.

Base and top remains same that is circular in shape.

Therefore, 1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.
