How would I do this what would he the answer

E.

Step-by-step explanation:

100,000 is the starting number. If it doubles each decade for 5 decades it'd be written like 100,000x2^5.

I'm quite sure this is correct if not then it's C.

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.

answer: y=0 if that is what u r looking for
