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 $r = 0.8903$

If the value of y varies directly with x when y=50, x=4. What is the value of y when x=2

den301095 [7]

Answer:

Step-by-step explanation:

The general equation for a direct variation is y = k*x

So your first step (usually) is to find k

y = k x

when x = 4

then y = 50

y = k*x
50 = k * 4 Divide by 4
50 / 4 = k*4/4
12.5 = k

Now you can find the value of y when x = 2

y = k*x
k = 12.5
x = 2
y = ?

y = 12.5 * 2

y = 25
