\bf \textit{Logarithm Change of Base Rule}\\\\
log_a b\implies \cfrac{log_c b}{log_c a}
\\\\\\
\textit{Logarithm Cancellation Rules}\\\\
\boxed{log_a a^x = x}\qquad \qquad a^{log_a x}=x\\\\
-------------------------------\\\\
log_{100}(50)\implies \cfrac{log_{10}(50)}{log_{10}(100)}\implies \cfrac{log_{10}(50)}{log_{10}(10^2)}\implies \cfrac{log(50)}{2}
\\\\\\
\cfrac{1.699}{2}\implies 0.8495

F (x) = 2 (x + 1)^2 - 1
Ivenika [448]

Answer:

Equation: y = x²

  • (-2, 4)
  • (0, 0)
  • (2, 4)

Equation: f(x) = 2(x + 1)² - 1

  • (-2, 1)
  • (0, 1)
  • (2, 17)

Step-by-step explanation:

Equation: y = x²

  • when x = -2, y = (-2)² = 4 ⇒ (-2, 4)
  • when x = 0, y = (0)² = 0 ⇒ (0, 0)
  • when x = 2, y = (2)² = 4 ⇒ (2, 4)

Equation: f(x) = 2(x + 1)² - 1

f(-2) = 2(-2 + 1)² - 1

      = 2(-1)² - 1

      =2(1) - 1

     = 1

Therefore, (-2, 1)

f(0) = 2(0 + 1)² - 1

     = 2(1)² - 1

      =2(1) - 1

     = 1

Therefore, (0, 1)

f(2) = 2(2 + 1)² - 1

     = 2(3)² - 1

      =2(9) - 1

     = 17

Therefore, (2, 17)

Fraction to Decimal Conversion  

(Math | General | Fraction to Decimal Conversion)

Fraction to Decimal Conversion Tables

Important Note: any span of numbers that is underlined signifies that those numbers are repeated. For example, 0.09 signifies 0.090909....

Only fractions in lowest terms are listed.  For instance, to find 2/8, first simplify it to 1/4 then search for it in the table below.  

 

fraction = decimal      

1/1 = 1      

1/2 = 0.5      

1/3 = 0.3 2/3 = 0.6    

1/4 = 0.25 3/4 = 0.75    

1/5 = 0.2 2/5 = 0.4 3/5 = 0.6 4/5 = 0.8

1/6 = 0.16 5/6 = 0.83    

1/7 =  0.142857 2/7 =  0.285714 3/7 =  0.428571 4/7 =  0.571428

 5/7 =  0.714285 6/7 =  0.857142  

1/8 = 0.125 3/8 = 0.375 5/8 = 0.625 7/8 = 0.875

1/9 = 0.1 2/9 = 0.2 4/9 = 0.4 5/9 = 0.5

 7/9 = 0.7 8/9 = 0.8  

1/10 = 0.1 3/10 = 0.3 7/10 = 0.7 9/10 = 0.9

1/11 = 0.09 2/11 = 0.18 3/11 = 0.27 4/11 = 0.36

 5/11 = 0.45 6/11 = 0.54 7/11 = 0.63

 8/11 = 0.72 9/11 = 0.81 10/11 = 0.90

1/12 = 0.083 5/12 = 0.416 7/12 = 0.583 11/12 = 0.916

1/16 = 0.0625 3/16 = 0.1875  5/16 = 0.3125 7/16 = 0.4375

 11/16 = 0.6875 13/16 = 0.8125 15/16 = 0.9375

1/32 = 0.03125 3/32 = 0.09375 5/32 = 0.15625 7/32 = 0.21875

 9/32 = 0.28125 11/32 = 0.34375 13/32 = 0.40625

 15/32 = 0.46875 17/32 = 0.53125 19/32 = 0.59375

 21/32 = 0.65625 23/32 = 0.71875 25/32 = 0.78125

 27/32 = 0.84375 29/32 = 0.90625 31/32 = 0.96875

Need to convert a repeating decimal to a fraction? Follow these examples:

Note the following pattern for repeating decimals:

0.22222222... = 2/9

0.54545454... = 54/99

0.298298298... = 298/999

Division by 9's causes the repeating pattern.

Note the pattern if zeros precede the repeating decimal:

0.022222222... = 2/90

0.00054545454... = 54/99000

0.00298298298... = 298/99900

Adding zero's to the denominator adds zero's before the repeating decimal.

To convert a decimal that begins with a non-repeating part, such as 0.21456456456456456..., to a fraction, write it as the sum of the non-repeating part and the repeating part.

 0.21 + 0.00456456456456456...

Next, convert each of these decimals to fractions. The first decimal has a divisor of power ten. The second decimal (which repeats) is converted according to the pattern given above.

 21/100 + 456/99900

Now add these fraction by expressing both with a common divisor

 20979/99900 + 456/99900

and add.

 21435/99900

Finally simplify it to lowest terms

 1429/6660

and check on your calculator or with long division.

= 0.2145645645...
