\sqrt{12}  -  \sqrt{48}  =

\sqrt{12}  -  \sqrt{4 \times 12}  =

\sqrt{4 \times 3}  -  \sqrt{4 \times 4 \times 3}  =

\sqrt{ {2}^{2} \times 3 }  -  \sqrt{ {4}^{2} \times 3 }  =

2 \sqrt{3}  -  4\sqrt{3}  =

find a positive angle less than one revolution around the unit circle that is co-terminal with the given angle -15pi/17
natta225 [31]
ANSWER
=\frac{19}{17} \pi

EXPLANATION

To find a positive angle that is coterminal with
-  \frac{15}{17}  \pi

We add multiples of 2π until we get a positive angle that is less than one revolution,


We add to obtain,


-  \frac{15}{17}  \pi + 2\pi


This simplifies to,

=  \frac{19}{17} \pi

This is the first positive angle that is coterminal with
-  \frac{15}{17}  \pi


and is less than one revolution.

DUE IN 30 MINS!!!<br> plz help T-T
-Dominant- [34]

Answer:

1. Tectonic activity is responsible for some of Earth's most dramatic geologic events: earthquakes, volcanoes and deep ocean trenches can all be formed by tectonic activity in the lithosphere.

2.The lithosphere can affect the atmosphere when tectonic plates move and cause an eruption, where magma below spews up as lava above. This can also release copious amounts of volcanic ash or soot, which pollutes the atmosphere, blocks radiation and creates a cooling effect.

3. I don't know what's show on the text sorry that parts up to you good luck :)

The ages of armadillos are normally distributed, with a mean of 14 years and a standard deviation of 1.2. Approximately what per
vovangra [49]

Answer:

Percentage of armadillos between 13 and 17 years = 79.052%f using Standard Normal Distribution Tables

Step-by-step explanation:

As we know from normal distribution: z(x) = (x - Mu)/SD

where x = targeted value; Mu = Mean of Normal Distribution; SD = Standard Deviation of Normal Distribution

Therefore using given data: Mu = 14, SD = 1.2 we have z(x) by using z(x) = (x - Mu)/SD as under:

Approach 1 using Standard Normal Distribution Table:

z for x=17: z(17) = (17-14)/1.2 gives us z(17) = 2.5

z for x=13: z(13) = (13-14)/1.2 gives us z(13) = -0.83

Afterwards using Normal Distribution Tables we find the probabilities as under:

P(17) using z(17) = 2.5 gives us P(17) = 99.379%

Similarly we have:

P(13) using z(13) = -0.83 gives us P(13) = 20.327%

Finally in order to find out the probability between 17 & 13 years we have:

Percentage of armadillos between 13 and 17 years = P(17) - P(13) = 99.379% - 20.327% = 79.052%

The standard normal distribution table is being attached for yours easiness.

Approach 2 using Excel or Google Sheets:

P(17) = norm.dist(17,14,1.2,1)

P(13) = norm.dist(13,14,1.2,1)

Percentage of armadillos between 13 and 17 years = { P(17) - P(13) } * 100
