Answer:
Step-by-step explanation:
1. 2 + 3{(4 - 1)2}
let solve the bracket first
2+3{(3)2}
2+3(9)
2 + 27
=29
2. 3y - ( x +2)
where x = -5 and y = 3
3(3) - (-5 + 2)
9 + 5 - 2
i multiply the bracket with negative sign
9 + 3
= 12
3. 2(4x - 3) + 3x
distribute
8x - 6 + 3x
combine the like terms
8x + 3x -6
Answer:
(-2,3)

Answer:
Step-by-step explanation:
hello :
note : y = A sin(Bt + C) + D
• amplitude is A
• period is 2π/B
in this exercice : f(t)= 1/2sin3t
amplitude is A
=1/2
period is 2π/3
Answer:
a^5x^5, 10a^5x^4, 40a^5x^3
Step-by-step explanation:
Use pascal's triangle for the first one
(2+x)^5 * a^5
= x^5a^5 + 5*2^1*x^4*a^5 + 10*2^2*x^3*a^5 ...
= a^5x^5 + 10a^5x^4+ 40a^5x^3 ...
