Scientists studying a bacteria sample find that after starting with 120 cells, the number of cells doubles every hour. Which of the following equations is a function that will predict C(h), the number of cells after h hours have passed?

C(h)=(120)(2)(h)
C(h)=120(2h)
C(h)=120(2)h
C(h)=120+2h

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
