Answer:

The mistake is that the equation on both sides is multiplied by 8. Both sides should be divided by 8.

Step-by-step explanation:

$8x^2-x-1=0$
$8x^2-x=1$ Divide both sides of the equation by 8
$x^2-\frac{1}{8} x=\frac{1}{8}$
$x^2-\frac{1}{8} x+?=\frac{1}{8} +?$ Add the same value to both side
$x^2-\frac{1}{8} x+\frac{1}{256} =\frac{1}{8} +\frac{1}{256}$
Use $a^2-2ab+b^2=(a-b)^2$
$(x-\frac{1}{16} )^2 = \frac{33}{256}$
$x-\frac{1}{16}=+-\frac{\sqrt{33} }{16}$
$x_{1} =\frac{-\sqrt{33}+1 }{16}$
$x_{2} =\frac{\sqrt{33}+1 }{16}$

ian invested $2500 in an investment vehical that would guarantee to earn 4% intrest yearly. the function for this is A(t)=2500(1

BartSMP [9]

A ( t ) = 2500 * (1.04) ^t
A ( t ) = 5000
5000 = 2500 * (1.04)^t
( 1.04 ) ^t = 5000 : 2500
(1.04)^t = 2
t = 17.68 ≈ 18
The value of t is 18 years.

Find the minimum, maximum, range, mean, and median for the data set.

Papessa [141]

Minimum: 37
maximum: 208
range: maximum - minimum = 208 - 37 = 171
mean: (37 + 43 + 54 + 83 + 102 + 117 + 160 + 208)/8 = 100.5
median: middle number (83 + 102)/2 = 92.5
