That is an arithmetic sequence of the form:
a(n)=2n-1
Now the sum of an arithmetic sequence is just the average of the first and last terms times the number of terms...
We know the first term is 1, let's find the last term...
a(1000)=2(1000)-1=1999
So the sum of that sequence is:
1000(1999+1)/2
1,000,000
Answer:
529 feet squared
Step-by-step explanation:
We know that the sides of a square are all the same length, and the formula to find the area of a square is length time width, so to find the area of the square we multiply 23 by 23, or square 23. 23 times 23 equals to 529 so the area of the square is 529 feet squared.
Answer:
ok so S=soda C=chips and G=gum
Step-by-step explanation:
From the information,
s+3=c
(1/2)c=g
from this P=s+c+g
P=s+(s+3)+((s+3)/2)
P=5/2s+9/2
Answer:
AD = 12 units
Step-by-step explanation:
AD = CD
so
4x = 10x-18
subtract 10x from both sides to get:
-6x = -18
divide each side by -6 to get:
x = 3
insert x into your problem and you get 4(3) which equals 12
