Answer:
f(x) = (x − 1)(x − 2)(x − 3)
Step-by-step explanation:
through the x axis at one; x = 1 factor (x - 1)
through the x axis at two; x = 2 factor (x - 2)
through the x axis at three; x = 3 factor (x - 3)
f(x) = (x − 1)(x − 2)(x − 3)
By using The half-angle formula
cos X/2 = ±√[(1 + cos X)/ 2]
But we have cos x=2/3
= ±√[(1 + 2/3)/ 2]
= ±√[(5/3 )/ 2]
= ±√[(5/5]
=±√1
Therefore answer is ±1
cos A/2 = ±√[(1 + cos A )/ 2]
Answer:
Area of the parallelogram is 99 inch²
Step-by-step explanation:
We are given that,
Base of the parallelogram = 11 inches
Height of the parallelogram = 9 inches
Since, we know,
Area of a parallelogram = Base × Height
So, we get,
Area of the parallelogram = 11 × 9 = 99 inch²
Hence, the area of the parallelogram is 99 inch².
Answer:
5
Step-by-step explanation:
(5-2)^2 + (7-3)^2 = radius^2
radius=√25
radius=5
