What is the sum of an 8-term geometric series if the first term is −11, the last term is 859,375, and the common ratio is −5? −1

LekaFEV [45]

Answer:

The sum of geometric series is 716144

Step-by-step explanation:

Given

First term=a_1= -11

Last term=a_8=859375

Common ration of geometric series=r= -5

And

Total terms in geometric sequence=n=8

We know that the formula for sum of geometric series is:

S_n= (a_1 (1-r^n))/(1-r)

= (-11(1-(-5)^8)/(1-(-5))

= (-11(1-5^8))/(1+5)

= (-11(1-390625))/6

=(-11(-390624)))/6

=4296864/6

=716144

So the sum of geometric series is: 716144 ..

Matt wants to hire a company to detail his car. Company A charges $15+17h where h represents the hours it takes to detail the ca

tensa zangetsu [6.8K]

Answer:

5 hours

Step-by-step explanation:

First, you set the equations equal, so 20h=17h+15

Second, you isolate the h, so you would subtract 17h from both sides, giving you 3h=15

Last, you divide both sides by 3 giving you h=5, meaning the companies charge the same price after 5 hours.

If a geometric sequence has a2 = 495 and a6 = 311, approximate the value of the common ratio ???? to four decimal

shtirl [24]

Answer:

$r = 0.8903$

Step-by-step explanation:

given,

a₂ = 495

a₆ = 311

geometric sequence formula

$a_n = ar^{n-1}$

$a_2 = ar^{2-1}$

$a_2 = ar$ ...................(1)

$a_6 = ar^{6-1}$

$a_6 = ar^5$ ................(2)

dividing equation (2) by (1)

$\dfrac{a_6}{a_2} = \dfrac{ar^5}{ar}$

$\dfrac{311}{495} = r^4$

$r^4 = 0.628$

$r = 0.8903$

hence, the common ratio of the geometric sequence is $r = 0.8903$
