Yes, the inverse is a function because it passes the horizontal line test.

It will a function because for every y we see only one x, so when it is going to be inverse for every x we will see only one y

Manuel wants to buy a new bicycle.He found one on sale for 10% off the original price.If the original price was $206.00, how muc

hram777 [196]

So, because the bike was 10% off, we know that the bike is now at 90% of its original value (100%-10% = 90%)
So to find the new value, we multiply the price by 90%:
0.9*206 = 185.4
The bike will cost Manuel $185.4

Find Integrating Fector: <br> ylogy dx + ( x-logy )dy=0

12345 [234]

Rewrite the ODE as

$y\log y\,\mathrm dx+(x-\log y)\,\mathrm dy=0\iff y\log y\dfrac{\mathrm dx}{\mathrm dy}+x=\log y$
$\dfrac{\mathrm dx}{\mathrm dy}=\dfrac1{y\log y}x=\dfrac1y$

so that it is now linear in $x$ . An integrating factor would

$\mu(y)=\exp\left(\displaystyle\int\frac{\mathrm dy}{y\log y}\right)=e^{\log(\log y)}=\log y$

Multiply both sides by $\mu(y)$ to get

$\log y\dfrac{\mathrm dx}{\mathrm dy}=\dfrac1yx=\dfrac{\log y}y$
$\dfrac{\mathrm d}{\mathrm dy}[x\log y]=\dfrac{\log y}y$
$x\log y=\displaystyle\int\frac{\log y}y\,\mathrm dy$
$x\log y=\dfrac12\log^2y+C$
$x=\dfrac12\log y+\dfrac C{\log y}$

(/25) 11111111.11111111.11111111.10000000 dotted decimal subnet mask equivalent: ________________________________ number of subn

hjlf

Count the number of 1 bits after the last decimal point. Call this number n.

There will be 2^n subnets and 2^(8-n) - 2 hosts per subnet. (You can mutilply the number of subnets by the number of hosts per subnet to find the total number of hosts.)

/25: 255.255.255.128, 2 subnets, 126 hosts per subnet

/26: 255.255.255.192, 4 subnets, 62 hosts per subnet

/27: 255.255.255.224, 8 subnets, 30 hosts per subnet

/28: 255.255.255.240, 16 subnets, 14 hosts per subnet

/29: 255.255.255.248, 32 subnets, 6 hosts per subnet

What is 7/10 times 8/21 in simplest form? Show work

Soloha48 [4]

Multiply the numerators: 7×8=56 then the denominators 10×21=210. The lowest multiples for 56 and 210 is 14. So divide 56/14=4 and 210/14=15. Your answer is 4/15.

Hope this helps (:
