Answer:
12.496
Step-by-step explanation:
Here, to calculate the sum of the first five terms of the series, we use the formula for the sum of terms in a geometric series.
Mathematically, that would be;
Sn = a(1-r^n)/1-r
where Sn = ?
a = 10
r = 1/5 = 0.2
n = 5
Substituting these values into the equation above, we have;
Sn = 10(1-(0.2)^5)/1-0.2
Sn = 10(0.99968)/0.8
Sn = 12.496
Hey!
-36 divided -6 is 6.........
Hello,
Answer C
y=2x-3.5==>2x-7=3.5 (1)
x-2y=-14 (2)
(1)-2*(2)==>3y=28+3.5 ==>y=31.5/3==>y=10.5
x=-14+2*10.5==>x=7
sol={(7,10.5)}
Answer: p = 3
Step-by-step explanation:
5p - 17 = -2
Add 17 to both sides
5p = 15
Divide both sides by 5
p = 3
