Given that r= 2p2/q-3 ; rearrange the formula to make q the subject of the formula.

Vesnalui [34]

Step-by-step explanation:

The given expression is:

$r=\dfrac{2p^2}{q-3}$

We need to solve it to make q the subject of the formula.

Cross multiplying both sides,

$rq-3r=2p^2$

Adding 3r to both sides,

$rq-3r+3r=2p^2+3r\\\\rq=2p^2+3r$

Now, dividing both sides by r,

$q=\dfrac{2p^2+3r}{r}$

Hence, this is the required solution.

Which one of the following is true when ds/st =3t^2/2s

Zina [86]

Middle school math! I actually know how to teach differential calculus to middle schoolers, but I wouldn't start with this example, where we're gonna have to integrate eventually.

We have

$\dfrac{ds}{dt} = \dfrac{3t^2}{2s}$

We have an odd mix of s and t on the right, which means this probably was an implicit derivative to begin with. In other words, instead of s as a function of t, we have some equation of s and t that is satisfied.

We move the variables to their respective sides

$2s \ ds = 3t^2 dt$

Integrating,

$s^2 =t^3 + C$

We only need one constant of integration.

I won't bother to write the square root. This is choice D.

For each shape in the table, list three examples of real-world objects that could be modeled by the shape. Use your experiences,

marishachu [46]

Interesting question. Let's see.

Rectangular Prism: any box (like a shoe box or a packing box).

Triangular Prism: We're not supposed to give personal answers, but I can't help it with this. When I was growing up, our front door's window had a triangular prism beveled around its edges. What made it so remarkable was that it broke up the light into a rainbow of colors on the floor.

Cylinder. Many drinking glasses are in the shape of a cylinder. Also old fashioned water towers were cylindrical in shape.

Cone: a kitchen funnel is an upside down cone. Some funnels don't have a spout, so that makes them true cones.

Pyramid: The pyramids for the Pharaohs in Egypt.

Sphere: Any ball (beach ball, baseball basketball soccer. Some storage shapes for spices -- technically not a perfect sphere). Planets. The sun. (The earth is almost a perfect sphere).
