Find the measures of two angles, one positive and one negative, that are coterminal with pi divided by five. How do you do this?

Anestetic [448]

$\theta= \frac{\pi}{5} 
$
$\\ \theta_1,\theta_2$ - coterminal angles

$\\ \theta_1= \frac{\pi}{5} +2\pi= \frac{\pi}{5} + \frac{10\pi}{5}= \frac{11\pi}{5} 
\\
\\ \theta_2= \frac{\pi}{5} -2\pi= \frac{\pi}{5} - \frac{10\pi}{5}=- \frac{9\pi}{5}$

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining Bismuth-210 transforms i

Luden [163]

Answer:

Approximately 76.5 mg.

Step-by-step explanation:

Given,

The initial quantity of the Bismuth-210, P = 233 mg,

Also, the rate of decay per day, r = 13 %

Thus, the quantity of the Bismuth-210 after 8 days would be,

$A=P(1-\frac{r}{100})^8$

$=233(1-\frac{13}{100})^8$

$=233(1-0.13)^8$

$=233(0.87)^8$

$=76.4733194697$

$\approx 76.5\text{ mg}$

Find the solution to the following equation.<br> 5x + 7 - x - 2 = 6x + 3x – 16<br> Please explain

konstantin123 [22]

Answer:

21/5 =x

Step-by-step explanation:

5x + 7 - x - 2 = 6x + 3x – 16

Combine like terms

4x +5 = 9x - 16

Subtract 4x from each side

4x+5 -4x = 9x-4x-16

5 = 5x-16

Add 16 to each side

5+16 = 5x-16+16

21=5x

Divide each side by 5

21/5 = 5x/5

21/5 =x
