Hello from MrBillDoesMath!
Answer:
- 8064 x^5 y^5
Discussion:
The binomial theorem gives us the expansion of (a + b) ^n :
(a + b ) ^n
= a^n + na^(n-1)b + (n(n-1)/ 2!) a^(n-2)b^2 +....
In our case, taking the 6th term above, setting a = 2x, b = -y, and n = 10 gives
( (10*9*8*7*6)/ (5 *4*3*2*1) ) * (2x)^5 (-y)^5r
= - 8064 x^5 y^5
Thank you,
MrB
Answer:
D. 8
Step-by-step explanation:
C= 2πr
π= 3.14
C= 25.12
25.12 = 2 * 3.14 * r
r= 4
d= 2r
d= 8
Answer:
1/10
Step-by-step explanation:
7/10
= .7
Eight taken away from five is equivalent to fourteen.
Thirteen added to seven equals five.
I don't understand the equation itself, but if those equations were to be actually written the way they were, then the above sentences are correct.
