The first term of an infinite geometric sequence is 18, while the third term is 8. There are two possible sequences. Find the sum of each sequence.

Answers

Answer:

Step-by-step explanation:

The sequence is geometric with

a = 18

Third term = 8.

Let the second term be x.

The infinite geometric sequence will be in the form

18,x,8,......

For geometric sequence, the ratio of two consecutive terms are equal. Hence, we have

$(x)/(18)=(8)/(x)\n\nx^2=144\nx=\pm12$

So, there are two possible sequences

18,-12,8,......

and

18,12,8,......

Thus, the common ratios are

$r=(-12)/(18),(12)/(18)\n\nr=(-2)/(3),(2)/(3)$

The sum of the infinite geometric for $r=(-2)/(3)$

$S=(a)/(1-r)\n\n(18)/(1-(-2)/(3))\n\nS=(18)/((5)/(3))\n\nS=(54)/(5)$

The sum of the infinite geometric for $r=(2)/(3)$

$S=(a)/(1-r)\n\n(18)/(1-(2)/(3))\n\nS=(18)/((1)/(3))\n\nS=54$

Hello,
Let'q the ratio
$u_(1) =18\n u_(2) =18*q\n u_(3) =18*q^2=8\ ==\ \textgreater \ q^2= (4)/(9) ==\ \textgreater \ q=\pm\ (2)/(3) \n1) if \ q= (2)/(3) \ then \ \sum_(i=0)^(\infty)\ 18* ((2)/(3) )^i= 18*(1)/(1+ (2)/(3) ) = (18*3)/(5)= 10.8\n\n2) if \ q= -(2)/(3) \ then \ \sum_(i=0)^(\infty)\ 18* (-(2)/(3) )^i= 18*(1)/(1- (2)/(3) ) = (18*3)/(1)= 54\n\n$

First you need to subtract both numbers and then, add them up. You'll receive e.g. 6-4=2 and 6+4=10, then just type them one after another, which will give you 6+4=210.

the soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation 5x + 10y = 800, where x represents the number of small vehicles and y represents the number of larger vehicles. If the number of larger vehicles washed was 50, how many small vehicles were washed in total?

Answers

5x+10y = 800
replace y by 50: 5x+10(50) = 800
5x+500 = 800
5x = 800-500
5x = 300
x = 300/5
x = 60
60 small vehicles were washed in total.

proof: 5x+10y = 800
replace x=60 and y=50
so; 5(60) +10(50) =800
300 + 500 = 800
800 = 800

Answer:

60 in total

Step-by-step explanation:

proof: 5x+10y = 800

replace x=60 and y=50

so; 5(60) +10(50) =800

300 + 500 = 800

800 = 800
