Answer: ∠MON = 15°
Step-by-step explanation:
∠LON = ∠LOM + ∠MON
(9x + 44) + (6x+3) = 77
9x + 6x + 44 + 3 = 77
15x + 47 = 77
15x = 30
x = 2
∠MON = 6(2) + 3 = 15
I’m no math teacher but I think it’s 13
Answer:
Y = √(R² - X²)
Step-by-step explanation:
∵ The two forces acting at right angles to each other
∴ The resultant force R = √(X² + Y²)
∴ R² = X² + Y²
∴ Y² = R² - X²
∴ Y = √(R² - X²)
Answer:
Step-by-step explanation:
A third degree polynomial has a <em>total of three roots</em>, real and imaginary combined.
If it already has 2 real roots, -4 and +4, then it has to have three real roots because imaginary roots come in conjugate pairs, i.e. they come in even numbers.
The work and answer provided are correct, the simpler way of doing it is
1)
1/6 page written in 1/12 of a minute
to write a full page, you would need to write 1/6, 6 times
so,

and

so it takes 1/2 of a minute to write a full page, there are 60 seconds in a minute, 1/2 of 60 seconds is 30 seconds
same process works for question 2(use 3 instead of 6 though)
