to get the circumference :)

Answer:

2.17 \times 10^{-1}

Step-by-step explanation:

(7 \times 10 ^{-6}) + 0.26 - (5 \times 10^{-2}) = \frac{7}{10^3} + \frac{26}{10^2}-\frac{5}{10^2}

                                              = \frac{7 + (26 \times 10) - ( 5 \times 10)}{10^3}\\\\=\frac{7 + 260 - 50 }{10^3}\\\\=\frac{217}{10^3}\\\\= 2.17 \times 10^2 \times 10^{-3}\\\\= 2.17 \times 10^{-1}

I need help with this
Kruka [31]

Answer:

<h2>V = 235.5 in³</h2>

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

r - radius

H - height

From the pictue we have r = 5in and H = 3in. Substitute:

x=\pi(5^2)(3)=\pi(25)(3)=75\pi\ in^3

\pi\approx3.14

Therefore

x=(75)(3.14)=235.5\ in^3

Which expression is equivalent to x^4 - 12x^2 + 36?
QveST [7]
So the answer is
(<span>x^2 plus or minus 6)(x^2 plus or minus 6)
an easy way to do this is to only look at plus or minus 6
x^4 <u><em>- 12</em></u>x^2 + <u><em>36   (-12 and 36)
</em></u><em />

<u><em /></u>6 x 6 = 36
<em />6 + 6 </span>≠ -12              (x^2 + 6)(x^2 + 6) is incorrect        
<span><u><em>
</em></u><em><u /></em><u />
6 x -6 </span>≠ 36
<span><em />6 + -6 </span>≠ -12             (x^2 - 6)(x^2 + 6) is incorrect
<span><em /><em>
</em><em />-6 x -6 = 36
<em />-6 + -6 = -12         </span><span>(x^2 - 6)(x^2 - 6) is correct
