SOLUTION
From the sequence give
–3, 1, 5, 9, . . .
The first term, a = -3
The common difference, d = 4 (gotten by adding 4 to the next term).
The number of terms required n = 6.
Formula for sum of an arithmetic sequence is given by
Substituting these values into the equation above we have
Hence, the answer is 42, option B
1. consecutive sides are thats next to each other so
DE,CD,EF,FG,HG
2. A&B, K& L, C&D, F&E, J&I
3. AB, KL, CD, JI, FE
4.A,B,K,H,G
One way is to just expand it by using binomial theorem
or to use pascal's triangle
ok so
to find the nth term of a binomial, (a-b). where the binomial is to the r power you do
n-1=k
rCk times
and rCk=
so
4th term
4-1=3
6 is exponent
6C3
=
=
=
the 4th term is
Answer:
8π units
Step-by-step explanation:
The circumference of a circle is calculated by using the following formula
2 × r × π (r: radius)
2 × 4 × π = 8π
x = number of miles you walk
5*x = amount of money the cousin donates
25 = amount of money your friend donates
5x+25 = total amount of money donated
y = total amount of money donated
y = 5x+25
Answer: y = 5x+25
