Test for the commutative property of union and intersection of the sets P = { x : x is all real numbers between 2 and 7} and Q =
In-s [12.5K]

Answer:

Step-by-step explanation:

P = {x : x is a real number between 2 and 7}

{x: 3,4,5,6}

Q = {x : x is all rational number between 2 and 7}

{4 }

We know that P contains all the rational numbers between 2 and 7.

And P ∪ Q and Q ∪ P each of them contain all the real numbers which are between 2 and 7.

{3,4,5,6}

Here Q is the proper subset of P

P ∩ Q = Q ∩ P = Q= {4}

A sphere with a diameter of 5 feet long is being painted. how much more paint would be needed to paint a sphere that has four ti
MArishka [77]

well, if the diameter is 5, thus its radius must be half that, or 2.5, and therefore, the radius of the one four times as much will be (4)(2.5).

Let's simply get their difference, since that'd be how much more is needed from the smaller to larger sphere.

~\hfill \stackrel{\textit{surface area of a sphere}}{SA=4\pi r^2}\qquad \qquad r=radius~\hfill \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{\large difference of their areas}}{\stackrel{\textit{radius of (4)(2.5)}}{4\pi (4)(2.5)^2}~~ - ~~\stackrel{\textit{radius of 2.5}}{4\pi (2.5)^2}}\implies 100\pi -25\pi \implies 75\pi ~~ \approx ~~235.62~ft^2

Please help!!!!!!!!!! !!
mestny [16]

Answer:

The ~length~ is ~9.6~ units ✔︎

༄❁༄❁༄❁༄❁༄

a=8\\b=2\\c=?\\d=?\\e=5

Using~ Pythagorean ~theorem:

c^2=a^2+b^2

c^2=(8)^2+(2)^2

\sqrt{c^2} =\sqrt{68}

c=\sqrt{68} ~or~2\sqrt{17}

»»---------------------►

d^2=c^2+e^2

d^2=(2\sqrt{17})^2+(5)^2

d^2=68+25

\sqrt{d^2} =\sqrt{93}

d=\sqrt{93} ~or~9.6

So, your~ answer ~is ~9.6
