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,

Answer:
Range : {11,27,43,59}
Step-by-step explanation:
Given:
f(x) = 4x - 1
Domain : {3,7,11,15}
f(3) = 4(3) -1 = 11
f(7) = 4(7) -1 = 27
f(11) = 4(11) -1 = 43
f(15) = 4(15) -1 = 59
hence Range : {11,27,43,59}

Answer:
B. 2cos3θsinθ.
Step-by-step explanation:
Use the identity
sin x - sin y = 2 [cos(x + y)/2]sin [x - y)/2].
So we have:
sin4θ - sin2θ = 2 cos (4θ+2θ)/2 sin (4θ-2θ)/2
= 2cos3θsinθ.
