Answer:
Answer A
Step-by-step explanation:
Angle A = 180 - 26 - 90 (90 right angle)
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos
(
A)=
adj/hyp
Cos (26) = a / 13
a = 13* Cos (26)
a= 11.7
Find the last side of the triangle using the Pythagorean theorem.
We want to expand (2x + y²)⁵.
From Pascal's Triangle (shown below), the coefficients of the expansion are
1,5,10,10,5,1.
n=0: 1
n=1: 1 1
n=2: 1 2 1
n=3: 1 3 3 1
n=4: 1 4 6 4 1
n=5: 1 5 10 10 5 1
Therefore the third term in the expansion is
10*(2x)³*(y²)² = 10*(8x³)*(y⁴) = 80x³y⁴
Alternatively, the third term is
₅C₃ (2x)³(y²)² = 10*(8x³)*(y⁴) = 80x³y⁴
Answer: 80x³y⁴
2 1/2
10 goes into 25 2 times with a remainder of 5 so , you get 2 5/10
5/10 reduces to 1/2
