T= sqrt(5/wc)
remove ( )
T= 5sqrt/wc
multiply by wc
Twc=5sqrt
divide by Tc
W= 5sqrt/cT
hope this helps
A1 = -7, an = 4(an - 1)
a2 = 4a1 = 4(-7) = -28
a3 = 4a2 = 4(-28) = -112
Therefore, the first six terms are -28, -112, -448, -1792, -7168, -28,672
Answer:
Positive
Step-by-step explanation:
(-9)-3=27
(-9)-2=18
(18)(27)=486
2d+4=10+2.5d
-2d -2d
4=10+0.5d
-10 -10
-6=0.5d
/0.5 /0.5
-12=d
d=-12
