Answer:
x = - 
Step-by-step explanation:
the equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
The radius of a unit circle is r = 1
substitute (x, - 
) into the equation and solve for x
x² + (- )² = 1²
x² + 
= 1 ( subtract from both sides )
x² = 1 - = 
( take square root of both sides )
x = ± 
= ±
since the point is in the 3rd quadrant then x < 0
x = -
Which graph? Please explain in the comments
Answer:
4 units
Step-by-step explanation:
Perimeter formula is P = 2L + 2W. Here P = 34 units = 2L + 2(6.5 units).
Reducing this, 17 = L + 13. Then L = 4 units.
Answer:
A
Step-by-step explanation:
Answer:
C. 0 6 10
Step-by-Step-Explanation:
the number on the left of the indicated operation is the original set
the number '2' next to R shows that you need to multiply certain numbers by 2
the subscript on the R's shows which row the multiplication needs to be done on...
so in this case, leave the second row alone: 1 3 4
but multiply the first row by 2: 0 6 10
