Which function is equivalent to y = 2(x – 4)^2 + 8?

Flura [38]

Answer:

B: y = 2x² - 16x + 40

Step-by-step explanation:

You can find this simply by expanding the given function:

y = 2(x - 4)² + 8

y = 2(x² - 8x + 16) + 8

y = 2x² - 16x + 32 + 8

y = 2x² - 16x + 40

If `f(x)=x^2-81` and `g(x)=(x-9)^(-1)(x+9)`, find `g(x)xxf(x)`.

marshall27 [118]

<u>Answer:</u>

$g ( x ) * f ( x ) = ( x + 9 ) ^ 2$

<u>Step-by-step explanation:</u>

We are given the following two functions and we are to find $g(x) * f(x)$ :

$f(x)=x2-81$

$g(x)=(x - 9)^{-1} ( x + 9)$

$g(x)*f(x)=x^{-81} * \frac{x+9}{x-9}$

$g ( x ) * f ( x ) =\frac{(x+9)(x-9)(x+9)}{x-9}$

$g ( x ) * f ( x ) = ( x + 9 ) ( x + 9 )$

$g ( x ) * f ( x ) =( x + 9 ) ^ 2$

The hydrogen ion concentration (h+) in a certain cleaning compound is (h+)=3.2x10^-11 use the formula ph=-log(h+) to find the pH

Furkat [3]

Answer:

The $pH$ of the clean compound is approximately 10.495.

Step-by-step explanation:

If the cleaning ion concentration of the cleaning compound is $[H^{+}] = 3.2\times 10^{-11}$ , then the $pH$ , no unit, of the compound is:

$pH = -\log_{10} [H^{+}]$ (1)

$pH = -\log_{10} (3.2\times 10^{-11})$

$pH = -\log_{10} 3.2 - \log_{10} (10^{-11})$

$pH = -\log_{10} \frac{32}{10} +11$

$pH = -\log_{10} 32 + \log_{10} 10 + 11$

$pH = -\log_{10} 32 +12$

$pH \approx 10.495$

The $pH$ of the clean compound is approximately 10.495.
