Are
you familiar with that?
------------
amp = 4
and
period=2 pi /4 = pi /2
42 + 5 * 32 - 42 ÷ 23
I am going to use the PEMDAS order. Parenthesis, Exponents, Multiply, Divide, Add, Subtract
Multiply ⇒ 5 * 32 = 160
42 + 160 - 42 ÷ 23
Divide ⇒ - 42 / 23 = -1.83
42 + 160 - 1.83
Add ⇒ 42 + 160 = 202
202 - 1.83
Subtract ⇒ 202 - 1.83 = 200.17
42 + 5 * 32 - 42 ÷ 23 = 200.17
Answer:
the amount of books grant has left
explanation:
if you take away b books, he is left with 29-b books
The answer is 9x⁴ᵃ - 24x²ᵃyᵃz³ᵃ + 16 y²ᵃz⁶ᵃ
(a - b)² = a² - 2ab + b²
(3x²ᵃ - 4yᵃz³ᵃ)² = (3x²ᵃ)² - 2 * 3x²ᵃ * 4yᵃz³ᵃ + (4yᵃz³ᵃ)² =
= 3²x²ᵃ*² - 2 * 3 * 4 x²ᵃ * yᵃz³ᵃ + 4²yᵃ*²z³ᵃ*² =
= 9x⁴ᵃ - 24x²ᵃyᵃz³ᵃ + 16 y²ᵃz⁶ᵃ
