What is the explicit rule of the sequence?
-182, -175, -168, -161, . . .

A- an=7n−189
B- an=7n−175
C- an=−7n−189
D- an=−7n−175

I think it is either C or D

One of the inventors of integrated circuits observed that the number of transistors that fit on an integrated circuit will double every 24 months. what type of relationship most appropriately models this situation?

Find the volume of the described solid.the solid lies between planes perpendicular to the x-axis at x = 0 and x=7. the cross sectionsperpendicular to the x-axis between these planes are squares whose bases run from the parabolay=-31x to the parabola y = 30/x.a) 441b) 147c) 864d) 882
