What is the vertex of the quadratic function f(x)=(x-8)(x-2) ?
Nata [24]
Multiply out <span>f(x)=(x-8)(x-2):  f(x) = x^2 - 8x - 2x + 16, or f(x) = 1x^2 - 10x + 16.
Thus, a=1, b= -10 and c=16.

One of several ways to find the vertex involves "completing the square."

x^2 - 10x + 16 = x^2 - 10x + 25 - 25 + 16, or y = (x-5)^2 -9, or y+9=(x-5)^2.

Compare this result to y-k = a(x-h)^2.  We see that h=5 and k=-9.

Thus, the vertex is at (h,k) = (5, -9). </span>

Ahmad sells beaded neckless each large necklace sells for $6.10 and each small necklace sells for $4.50 how much will he earn fr
Ilya [14]

Answer:

The answer is $22.80

Step-by-step explanation:

<h3><u>Given</u>:</h3>

Ahmad sells beaded neckless each large necklace sells for $6.10 and each small necklace sells for $4.50.

If Ahmad will sell 3 large necklaces and 1 small necklace then,

3 × $6.10 = $18.30

So, $18.30 + $4.50 = $22.8

Thus, If Ahmad will sell 3 large necklaces and 1 small necklace then he will earn $22.80.

Two large numbers of the Fibonacci sequence are F51 = 20,365,011,074 and F52 = 32,951,280,099.What is the approximate value of t
Katen [24]
With the Fibonacci Sequence, we keep adding the 2 previous numbers
1
+1
=2

then
1
+2
=3

2 +
3
=5

And we can continue
<span> <span> <span> 8 </span> <span>
13
</span> <span> 21
</span> <span> 34 </span> <span>
55 </span> <span>
89 </span>
<span> 144 </span>
<span> 233 </span>
<span> 377 </span> </span> </span>

If we take a Fibonacci number and divide it by the PREVIOUS Fibonacci number (For example 377 / 233) we get:
<span> <span> <span> 1.61802575107296 </span> </span> </span>

This is something known as the phi ratio, which equals (1 + sq root(5)) / 2
or <span> <span> <span> 1.6180339887499</span></span></span>
The further we carry out the Fibonacci sequence, the closer the division of (Fibonnaci Number "n") /(Fibonnaci Number "n-1") gets to be
(1 + sq root(5)) / 2
So, I would say that F52 / F51 would  <span><span><span>equal 1.6180339887499 or be very close to it.
Look up the "Golden Ratio" in wkipedia
