Remember, a/(c/d)=(a)(d/c)
subsitute 1/2 for x

$f(x)=\frac{1}{\frac{1}{2}}=(1)(\frac{2}{1})=2$

How do you solve an inequality like this/<br><br> x-2/x+16 ≥ 0

neonofarm [45]

$\bf \cfrac{x-2}{x+16}\ge 0\implies \stackrel{cross-multiplying}{x-2\ge (x+16)0}\implies x-2\ge 0\implies x\ge 2$

Help me answer this question

Elden [556K]

Ok, so basically, the amount of orange pics is 3/5.
I think better w/ visuals, so i drew 5 circles, and colored 3 orange
Since the 3 circles represent 12 picks (because there are 12 picks total and 3/5 of the picks are orange) you nee to find out how many picks 1 circle represents.
In order to find this, do 12/4=3
One circle equals 3 picks
multiply 3 by 5, and you get 15
Hope this helps because this is a better explanation for visual learners!

Rewrite the expression as an algebraic expression in x.<br> tan(sin−1(x))

solmaris [256]

Let $tan^{-1} x=\alpha$
Then it can be shown by using a right-angled triangle and the rule of Pythagoras that $\alpha= tan^{-1} \frac{x}{ \sqrt{1-x^{2}} }$
Therefore
$tan(sin ^{-1} (x))=\frac{x}{ \sqrt{1-x^{2}} }$

Question 15(Multiple Choice Worth 1 points)

Sphinxa [80]

In f(x) = 16(0.75)x the (0.75) does not have a 1 so it is decreasing and if it is only 75% of 16 then it would be losing 25% each time So the exponential decay will be 25%.
