Help Me Plz A music producer is making a list of vocalists needed to record an album. For each day of recording, a different number of vocalists are needed. The first day, seven vocalists are needed. Each day after that, the number of vocalists needed doubles. The producer must pay by the day for each vocalist. To find the total price, the producer needs to know how many vocalists sang in total at the end of the 10th day. Use a series to find the sum after the 10th day. 7,168 7,161 3,584 3,577

7161

Step-by-step explanation:

Now we need to find the sum for a series

The formula is

Sn =   (first term)*(1 - r^n)/(1-r)  where n is the number of days and r is the rate

     = 7( 1 -2^10)/ (1-2)

     = 7( -1023)/-1

     = 7161

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
