(hg^(-3))/(w^(-4) k^0 )

Svetlanka [38]

One may note you never quite asked anything, now, assuming simplification,

$\bf ~~~~~~~~~~~~\textit{negative exponents}\\\\
a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad 
a^n\implies \cfrac{1}{a^{-n}}
\\\\
-------------------------------\\\\
\cfrac{hg^{-3}}{w^{-4}k^0}\implies \cfrac{hw^4}{g^3(1)}\implies \cfrac{hw^4}{g^3}$

Need some help with this question

Elza [17]

Answer:

5 units down.

Step-by-step explanation:

D' is the translated image. If D' is at (7,1) and the original point, D, is at (7,6), we can see a change of -5 in the y coordinate. This means that there was a translation of 5 units down.

A sphere and the base of a cone have a radius of 3 inches. The volume of the sphere equals the volume of the cone. what is the h

Valentin [98]

So the volume of a sphere is $V= \frac{4}{3} \pi r^3$ , and the volume of a cone is $V= \pi r^2 \frac{h}{3}$ (h=height, r=radius). Knowing only the radius, we can solve for the volume of the sphere. (Also I'm going to be leaving answers in pi form.)

$V= \frac{4}{3} \pi 3^3$
Solve the exponents to get $V= \frac{4}{3} \pi 9$
Multiply 4/3 and 9 to get $V=13.5 \pi$

Now that we know the volume of the sphere, we can solve for the height of the cone since the volumes for both are the same.

$13.5 \pi = \pi 3^2 \frac{h}{3}$

Solve the exponents to get $13.5 \pi =9 \pi \frac{h}{3}$

Divide $9 \pi$ on each side to get $1.5= \frac{h}{3}$

Multiply 3 on each side, and your answer should be $4.5=h$
