U = - 4 i + 1 j
v = 4 i + 1 j
| u | = √ (-4)² + 1² = √ 17
| v | = √4² + 1² = √ 17
| u + v | = √(u + v)²=
= √( u² + 2 u v + v² )= ...
cos ( u, v ) = (-16+1) / (|u| |v|) = -15/17
...= √(17 + 2 · √17 · √17 · ( -15/17) +17) =
= √ 34 - 30 = √ 4 = 2
Answer: C ) 2
A parallelogram is a four-sided figure with opposite sides parallel.
15?im not sure...but I think thats right
Step-by-step explanation:
(x+3)(x-5)
= x²-5x+3x-15 = x²-2x-15
But the given polynomial x³-15
So it is not the correct factorization.
Again, (x-3)(x+5)
= x²+2x-15
But the given polynomial x³-15
So it is not the correct factorization.
Again , (x+3)(x²-4x+5)
= x³-4x²+5x+3x²-12x+15
= x³-x²-7x+15
But the given polynomial x³-15
So it is not the correct factorization.
So , optionD is the correct answer
Answer:
Expanded Notation Form:
500,000 = 500,000 + 0 + 0 + 0 + 0 + 0
Expanded Factors Form:
500,000 = 5 × 100,000 + 0 × 10,000 + 0 × 1,000 + 0 × 100 + 0 × 10 + 0 × 1
Expanded Exponential Form:
500,000 = 5 × 10⁵ + 0 × 10⁴ + 0 × 10³ + 0 × 10² + 0 × 10¹ + 0 × 10⁰
Word Form:
500,000 = Five hundred thousand
Step-by-step explanation:
Because math says so..
