Answer:
6825
Step-by-step explanation:
From the equation, the series is a geometric series, such that
a = 5
r = 4
n = 6
sum of a geometric series is a(r^n - 1)/(r - 1)
therefore,
sum of the series is 5 x (4^6 - 1) / (4 - 1)
= 5 x (4096 - 1) / 3
= 5 x 4095 / 3
= 6825
the answer is the second option (-5,1)
Hello
<span>an equation for the line in point-slope form and general form is :
y = ax+b a : </span>slope ; the <span>Passing through (x' ; y')
</span>y' = ax'+b
y-y' =a(x-x') and : x' =8 y' = -4
calculate a :
let : y = ax+b .....(D)
....(D') y = (1/5)x+4
.(D) perpendicular to(D') : slope (D) × slope (D') = -1
slope (D') = 1/5
slop(D)×(1/5) = -1
slope (D) = -5
equation for the line : y-y' =a(x-x')
y+4 =(-5) (x-8)
