Number 4 and 6 are correct because you can only add variables with other variables so that is why 4 and 6 are correct
Answer:
ASC X12
Step-by-step explanation:
The Accredited Standards Committee X12 (also known as ASC X12) is a standards organization. Chartered by the American National Standards Institute (ANSI) in 1979, it develops and maintains the X12 Electronic data interchange (EDI) and Context Inspired Component Architecture (CICA) standards along with XML schemas which drive business processes globally.
2x^2 + 17x -21 cannot be factored nicely, if it was +21 you could, but the zeros for this have to gotten using the quadratic equation
-b +/- (b^2-4ac)^1/2
2a
so
-17 +/- (17^2-4(2)(-21))^1/2
2(2)
-17 +/- (457)^1/2
4
so the zeros are roughly 1.094 and -9.594
sin 3 x = sin ( 3 x + 2 π ) = sin [ 3 ( x + 2 π/ 3 ) ] = sin 3 x
This means "after the arc rotating three time of ( x + ( 2 π /3 ) ) , sin 3x comes back to its initial value"
So, the period of sin 3x is 2 π /3 .
Answer:
about 113.04 square inches
Step-by-step explanation:
No angles are indicated, so we must assume the sector is 1/4 of the circle. Then its area is 1/4 of that of a circle with radius 12 in:
Circle area = πr²
Sector area = (1/4)π(12 in)² = 36π in²
Sector area ≈ 36(3.14) in² = 113.04 in²
