Answer:
Answer: 45
Step-by-step explanation:
Well it seems like your answer would follow along with is:
`18x2.5=45
Hope this helps good sir!
9 - 6 + 4 - 8/3 ..,
geometric series a(n) = a1r^(n-1)
r = a(n+1)/a(n)
-6/9 = -2/3
4/-6 = -2/3
-8/3/4 = -2/3
so r = -2/3 and a1 = 9
Sn = a1(1-r^n)/(1-r) = 9(1-(-2/3)^n)/(1-(-2/3))
n is infinite Sn = 9/(5/3) = 27/5
Around 14 weeks
45*14=630
675-630=45
So around 14 weeks
Hope it cleared your doubt.
0,-5,8
To find the zeros, set each equation equal to 0
x=0
x+5=0
x-8=0
Then solve
x=0
x=-5
x=8
So the zeros are 0,-5, and 8
