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
Answer:
$54.50 would be your answer
Step-by-step explanation:
$80 as a decimal is 0.80
This means that 37.5 x 0.80 which is 30 will be taken off, so the printer is $30 off.
$80 - 30 off, so the pirinter sells for $50
sales tax is 9% on the price of $50, so multiply 50 by 1.09.
50 x 1.09 = 54.5
Therefore the final price is $54.50
Answer:
Step-by-step explanation:
Vertical asymptotes are
vertical lines which correspond to the zeroes of the denominator of a
rational function<span>.
(They can also arise in other contexts, such as logarithms, but you'll
almost certainly first encounter asymptotes in the context of rationals.) I'll give you an example:
</span>
This is a rational function.
More to the point, this is a fraction. Can you have a zero in the denominator
of a fraction? No. So if I set the denominator of the above fraction equal
to zero and solve, this will tell me the values that x
cannot be:
x2
– 5x – 6 = 0<span>
</span>(x
– 6)(x + 1) = 0<span>
</span>x
= 6 or –1
So x
cannot be
6 or –1,
because then I'd be dividing by zero.
<span>
<span><span>
<span>
</span></span><span><span /><span>
</span>
</span>
</span></span>
The domain is the set
of all x-values
that I'm allowed to use. The only values that could be disallowed are
those that give me a zero in the denominator. So I'll set the denominator
equal to zero and solve.
<span>x2
+ 2x – 8 = 0</span><span>
</span><span>(x
+ 4)(x – 2) = 0</span><span>
</span><span>x
= –4</span> or <span>x
= 2</span>
Since I can't have a
zero in the denominator, then I can't have <span>x
= –4</span> or <span>x
= 2</span> in the domain.
This tells me that the vertical asymptotes (which tell me where the
graph can <span>not
</span>go) will be at the
values <span>x
= –4</span> or <span>x
= 2</span>.
domain:
<span>
</span><span>vertical
asymptotes: <span>x
= –4</span>,<span>
2</span></span>
<span>
<span>
</span></span>
