Which statement are true
Ket [755]

Answer:

  • Line XY contains ray OX and ray OY
  • Line XY contains segment YX
  • Ray YX exists in the diagram

Step-by-step explanation:

A ray can be named by any pair of points on an infinite line. Point O, X, and Y on the same line can be used to name rays OX, OY, XY, YX, OY, and XO. The first point named is the end point of the ray. The ray goes through the other point and continues indefinitely.

BA can be the name of a line segment, but not a ray. The line shown does not extend from point B beyond point A.

Any segment can be named by its end points in either order.

So, we have ...

  • Line XY contains ray OX and ray OY
  • Line XY contains segment YX
  • Ray YX exists in the diagram

The radius of a right circular cylinder is given by √(t+6) and its height is 1/6√t , where t is time in seconds and the dimensio
denis23 [38]

Answer:

The rate change of volume of the cylinder is \frac{\pi}{4} ( \sqrt t+\frac2{ \sqrt t}) cubic inch per second.

Step-by-step explanation:

Given that the radius of right circular cylinder is \sqrt{(t+6)}  and its height is \frac16 \sqrt t where t is time in second and the dimension are inches.

\therefore r = \sqrt{(t+6)}

The base area of the cylinder is A= \pi r^2

                                                        =\pi (\sqrt{t+6})^2

                                                       = \pi (t+6)

\therefore A= \pi(t+6)

Differentiating with respect to t

\frac{dA}{dt}=\pi

\therefore h=\frac16\sqrt t

Differentiating with respect to t

\frac{dh}{dt}=\frac16 \times \frac12(t)^{\frac12-1}

\Rightarrow \frac{dh}{dt}=\frac1{12} (t)^{-\frac12}

The volume of cylinder is V= Ah

∴V= Ah

Differentiating with respect to t

\frac{dV}{dt}=A\frac{dh}{dt}+h\frac{dA}{dt}

    =\pi (t+6). \frac1{12}t^{-\frac12} +\frac16\sqrt t . \pi

   =\pi. \frac1{12}.t^{\frac12}+\pi . 6.\frac1{12} t^{-\frac12} +\pi\frac16 \sqrt t

   =\frac{\pi}{4} ( \sqrt t+\frac2{ \sqrt t})

The rate change of volume of the cylinder is \frac{\pi}{4} ( \sqrt t+\frac2{ \sqrt t}) cubic inch per second.
