HELP ME ASAP!!!

Olenka [21]

Answer:

21.6 liters

Step-by-step explanation:

40 drops make up a volume of 10 mL

Therefore, the volume of 1 drop of water = 10mL/40 = 1/4 mL= 0.25mL

Since the tap loses 1 drop of water in 1 sec, it loses 0.25mL of water in 1 second

60 seconds make up 1 second so volume of water lost in 1 minute = 0.25 x 60 = 15 mL

60 minutes make up 1 hour so volume of water lost in 1 hour = 15 x 60 = 900 mL

24 hours make up a day so volume of water lost in 1 day = 900 x 24 = 21,600 mL

Since 1000 mL make up 1 liter, divide by 1000 to get volume in liters

Volume of water lost in 1 day = 21600/1000 = 21.6 liters

Can be done as one equation

V lost in one day = 0.25 x 3600 x 24 mL = 21600 mL = 21.6 L

Study the geometric sequence {-4, -84, -1764, -37044, ...}.

Nonamiya [84]

Answer:

$\bold{a_n=(-4)21^{n-1}}$

Step-by-step explanation:

$a_1=-4\,,\ a_2=-84\,,\ a_3=-1764\,,\ a_4=-37044\quad\implies\ \ r=21$

{-84:(-4)=21 and -1764:(-84)=21 and -37044:(-1764)=21}

geometric sequence formula: $a_n=a_1r^{n-1}$

$a_1=-4\quad and \ \ r=21$

$a_n=(-4)21^{n-1}$
