Answer:
Step-by-step explanation:
Sum = -14
Product = - 32
So, the factors = -16 , 2
When we add -16 +2 = -12 and when we multiply it is -32
w⁴ - 14w² - 32 = w⁴ - 16w² + 2w² - 16 * 2
= w²(w² - 16) + 2(w² - 16)
= (w² - 16)(w² + 2)
= (w² - 4²)(w² + 2)
= (w + 4)(w - 4)(w² + 2)
Answer:
Step-by-step explanation:
Triangle BCD is a right angle triangle.
From the given right angle triangle
BC represents the hypotenuse of the right angle triangle.
Taking 45 degrees as the reference angle,
BC represents the adjacent side of the right angle triangle.
BD represents the opposite side of the right angle triangle.
To determine BC, we would apply trigonometric ratio
Cos θ = adjacent side/hypotenuse side. Therefore,
Cos 45 = BC/2√2
√2/2 = BC/2√2
BC = 2√2 × √2/2
BC = 2
3636 times. 1000000 divided by 275 equals 3636.36363 repeating
Answer:
the first four
Step-by-step explanation:
The last two do not equal 9 or .90
Answer:
c = 10
Step-by-step explanation:
Using Pythagoras' theorem
The square on the hypotenuse of a right triangle is equal to the sum of the squares on the other 2 sides, that is
c² = a² + b² ← substitute values
c² = 6² + 8² = 36 + 64 = 100 ( take the square root of both sides )
c = 
= 10
