Perimeter of triangle is calculated by adding up the three sides of the triangle.

In the given triangle ABC, vertices of triangle are given as A(-2,2) B(0,4) C(1,-2)

We calculate the length of side AB by the distance formula which states as :

For the points (x_{1},y_{1}) and (x_{2},y_{2})

distance =\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}

AB = \sqrt{(0+2)^{2} + (4-2)^{2}} = 2\sqrt{2}

BC=\sqrt{(1-0)^{2} + (-2-4)^{2}} = \sqrt{37}

AC=\sqrt{(1+2)^{2} + (-2-2)^{2}} = 5

Perimeter = AB+BC+AC = =2\sqrt{2} + 5+ \sqrt{37}= 13.911

So, Perimeter = 14 (Rounded to the nearest tenth)

if an alien species ages a year every human month, how old would they be, in human years, by the time they're 2,000 in their spe
DENIUS [597]
Hey there!
If they're 2,000 in their time, then they must have went through 2,000 months given that they aged 1 year/month.
That means we're converting 2,000 months into years.
Because 12 months is a year, we divide 2,000 into groups of 12 (2,000/12)
to get 166 as our closest whole number. 12 times 166 is 1,992, so the remainder is 8 months.
Therefore, the aliens are 166 years and 8 months in human time.
Hope this helps!

saul85 [17]

In normal distributions, the 95th percentile is a value exists within 2 standard deviations of the mean.

The mean is 175 lbs. and SD is 15 lbs. This means that Harvey's mass will be inside 2 standard deviations (respectively) of the mean. In other words, his weight will be in the range 145 - 205 Lbs.
