if QRST is indeed a quadrilateral, then, Check the picture below.
El valor absoluto de 26 is 26 |26|=26
Puedes decir que el valor absoluto de un número es el mismo número solo tiene que ser positivo
|-26|=26
|2|=2
|-59|=59
|-1/2|=1/2
Find the distance (in coordinate plane units) from (-4,10) to (-10,-1).
The change in x will be -6 and the change in y will be -11.
Thus, the distance between the 2 pts is, by the Pythagorean Theorem,
sqrt( [-6]^2 + [-11]^2 ) = sqrt(157).
Convert this to miles:
sqrt(157 units^2) = 12.6 units
1.55 mi
12.6 units * ------------- = 19.4 miles (answer)
1 unit
n = 15
the nth term of an arithmetic sequence is 
= a₁ + (n-1)d
where d is the common difference
d = a₂ - a₁ = 6 - 2 = 4
= 2 + 4n - 4 = 58
4n - 2 = 58
4n = 60 ( divide both sides by 4 )
n = 15
Where is the picture. i cant imagine
