Answer:
The sixth term of the binomial expansion is;
10C5 (5y)^5 (3)^5
Step-by-step explanation:
Here, we want to select which of the options represent the 6th term of the binomial expansion;
(5y + 3)^10
We should know that while the powers of 5y will be increasing, the powers of 3 will be decreasing.
We can write the terms as follows;
10C0(5y)^10(3)^0 + 10C1(5y)^9(3)^1 + 10C2(5y)^
8(3)^2 + 10C3(5y)^7(3)^3 + 10C4(5y)^6(3)^4 + 10C5(5y)^5(3)^5 + ............
Sum of the angles of any quad =360
then y+(x+2)+(x-2)+(x-10) = y +3x -10 =360 (by adding both sides by 10)
y + 3x =370 ;.... eq 1
the sum of each two opposite sides in a quad inscribed in a circle =180
then (x+2)+(x-2)=180
therefore 2x =180
therefore x=90 (sub in eq 1)
y+3*90 =y +270 = 370 (subtracting both sides by 270)
therefore y=100
then measure angle B=100 degrees
A=92 degrees
C=88 degrees
D=80 degrees
I know that one other form is
800,000+1,000+6
The value of x is 150. I subtracted 180-30 to get 150.
