Answer:

Circular paraboloid

Step-by-step explanation:

Given ,

$r(s,t)=ssin4t,s^2,scos4t$

Here, these are the respective $x,y,z$ axes components.

Component along x axis $r_i : ssin4t$

Component along y axis $r_j : s^2$

Component along z axis $r_k : scos4t$

We see that , from the parameterised equation , $r_i^2+r_k^2=s^2sin^24t+s^2cos^24t\\r_i^2+r_k^2=s^2\\r_i^2+r_k^2=r_j$

This can also be written as :

$x^2+z^2=y$

This is similar to an equation of a parabola in 1 Dimension.

By fixing the value of z=0,

We get $y=x^2$ which is equation of a parabola curving towards the positive infinity of y-axis and in the x-y plane.

By fixing the value of x=0,

We get $y=z^2$ which is equation of a parabola curving towards positive infinity of y-axis and in the y-z plane.

Thus by fixing the values of x and z alternatively , we get a CIRCULAR PARABOLOID.

Please help IM TIRED :,)

Ad libitum [116K]

It states that the chef makes 20.5 servings, and that each serving holds 3.275 ounces, so to find the total amount of sauce the chef made you would multiply the number of servings by the volume of each serving, which is 20.5*3.275= 67.1375

There are four decimal places in the product of 67.1375 total ounces of sauce.

Answer:

$\boxed{\sf A}$

Step-by-step explanation:

$\sf 1 \ gallon = 3785.41 \ cm^3$

$\sf 5 \ gallon = \ ? \ cm^3$

$\sf Multiply \ the \ gallon \ value \ by \ 3785.41.$

$5 \times 3785.41 = 18927.1$

$\sf Approximate \ the \ value.$

$18927.1 \approx 19000$
