To solve the third term of 10-n², substitute the number 3 for n.
10-n²
=10-3²
=10-9
=1
The third term of 10-n² is 1.
Standard deviation is equal to the square root of the variance. To arrive at this work out the mean, then subtract the mean and square the result of each number. Then work out the mean of those squared differences and take the square root of that.
It's about 34 and a third
(A)squared plus (B) squared = (c)squared
pythagrem therom a squred + b squared =c squared
No. For it to work, then 3 squared and 4 squared would have to be equal to 6 squared. 4 squared=16 3 squared= 9 9+16= 25 6 squared= 36.
x = 0.83333 10x = 8.3333 100x = 83.3333 Subtract the second from the third. 90x = 75 x = 75/90 Reduce. x = 5/6

pythagorean therom add them both together and subtract from 180vv LAW OF COSINE vva^2 = b^2 + c^2 - 2(b)(c)CosAOther Answer1) If you have a perimeter you can subtract the first two from the total perimeter.2) If it is a right triangle and you are missing the hypotenuse (the slanted one), the formula a^2 + b^2 = c^2 is used. (Words-- A squared plus B squared equals C squared.)(A) is the length that is upright, (B) is the length that is sideways, and (C) is the hypotenuse, or the answer.If you have a right triangle you can work that question backwards.If you have any questions you can email me. My screen name is Eparisahana.
The Longest Side (Hypotenuse) Squared is equal to the adjacent side squared plus the opposite side squared, or in mathematical terms: a2= b2+ c2
Trial and error. You know that the answer will be between 2 and 3, closer to 3. 2.8 squared = 7.84 2.82 squared = 7.95 2.828 squared = 7.99 2.8284 squared = 7.999 which is close enough for me.
In a right angle triangle the base squared (a) plus the height squared (b) is equal to the hypotenuse squared (c) Pythagoras' theorem: a2+b2 = c2
