The price of gold is often reported per ounce. At the end of 2005, this price was $513. At the end of 2015, it was $1060. By wha

erastova [34]

Answer:

106.63%.

Step-by-step explanation:

We have been given that at the end of 2005, this price was $513. At the end of 2015, it was $1060.

To find the percentage of the price per ounce of gold increase we will use % increase formula.

$\text{Percent Increase}=\frac{\text{Final value-Initial value}}{\text{Initial value}}\times 100$

Let us substitute our given values in above formula.

$\text{Percent Increase}=\frac{1060-513}{513}\times 100$

$\text{Percent Increase}=\frac{547}{513}\times 100$

$\text{Percent Increase}=1.0662768031189084\times 100$

$\text{Percent Increase}=106.62768031189084\approx 106.63$

Therefore, the price of per ounce of gold increased by 106.63%.

Find the absolute maximum and minimum values of the following function on the given interval. If there are multiple points in a

Bond [772]

$f(x)=3\sin x+3\cos x\implies f'(x)=3\cos x-3\sin x$

$f$ has critical points where $f'=0$ :

$3\cos x-3\sin x=0\implies\cos x=\sin x\implies\tan x=1\implies x=\pm\dfrac\pi4+2n\pi$

where $n$ is any integer. We get solutions in the interval $\left[0,\frac\pi3\right]$ for $n=0$ , for which $x=\frac\pi4$ .

At this critical point, we have $f\left(\frac\pi4\right)=3\sqrt2\approx4.243$ .

At the endpoints of the given interval, we have $f(0)=3$ and $f\left(\frac\pi3\right)=\frac{3+3\sqrt3}2\approx4.098$ .

So we have the extreme values

$\max\limits_{x\in\left[0,\frac\pi3\right]}f=3\sqrt2$

$\min\limits_{x\in\left[0,\frac\pi3\right]}f=3$
