What is the growth percentage of h(x) = .5(2)" ?A200%B2%100%D10%

zaharov [31]

$h(x)=0.5(2)^x^{}$

We can compute the growth percentage, computing first, two consecutive values, as follows:

$\begin{gathered} h(1)=0.5(2)^1=0.5(2)=1 \\ h(2)=0.5(2)^2=0.5(4)=2 \end{gathered}$

Then, the growth percentage is:

$\frac{h(2)-h(1)}{h(1)}\cdot100=\frac{2-1}{1}\cdot100=100\text{ \%}$

2w-1 divided by 5+w+2=2w

FromTheMoon [43]

Answer:

(2w-1)/5+w+2=2w

We simplify the equation to the form, which is simple to understand

(2w-1)/5+w+2=2w

Reorder the terms in parentheses

( + 0.4w-0.2)+w+2=2w

Remove unnecessary parentheses

+ 0.4w-0.2+w+2=2w

We move all terms containing w to the left and all other terms to the right.

+ 0.4w+1w-2w=0.2-2

We simplify left and right side of the equation.

-0.6w=-1.8

We divide both sides of the equation by -0.6 to get w.

w=3

SpyIntel [72]

Answer:

y = - 5

Step-by-step explanation:

$log_{2}( \frac{1}{32} ) = y \\ \\ log_{2}( \frac{1}{ {2}^{5} } ) = y \\ \\ log_{2}( {2}^{ - 5} ) = y \\ \\ {2}^{ - 5} = {2}^{y} \\ \\ - 5 = y \\ \\ \huge \red{ \boxed{y = - 5}}$
