Find the 7th term of the geometric sequence with the given terms.

ohaa [14]

Answer:

1. 1458

2. 500 or -500

Step-by-step explanation:

1. a4=54, a5=162

r = 162/54 = 3

a7 = a5 × r²

= 162 × 3² = 1458

2.a4=-4, a6=-100

r² = -100/-4 = 25

r = +/- 5

a7 = a6 × r

= -100 × +/- 5

= +/- 500

Write a vector equation of the line that passes through p(–1 6) and is parallel to a = (3, -1).

Phoenix [80]

Answer:

Step-by-step explanation:

(x,y) = p + t(a)

(x,y) = (-1,6) + t(3,-1)

(x,y) - (-1,6) = t(3,-1)

(x + 1, y - 6) = t(3, -1)

A few years ago, a total of 2669 thousand people lived in the metropolitan areas of Las Vegas, Nevada, and Sacramento, Califo

aniked [119]

Let's make equation for this problem. Let's say the population of LV is x, then Sacramento will be x+275 since <span>Sacramento had 275 thousand more residents than Las Vegas. Remember that their total population is 2669, so your equation will be </span> $x+275 +x=2669$

If you solve this equation, you have x=1197, that is population of LV. So Sacramento is 1472.
