Because
therefore
f(x) = (x-3)(2x² + 10x - 1) + k, where k = constant.
Because f(3) = 4, therefore k =4.
The polynomial is
f(x) = 2x³ + 10x² - x - 6x² - 30x + 3 + 4
= 2x³ + 4x² - 31x + 7
Answer: f(x) = 2x³ + 4x² - 31x + 7
Answer:
1.25π
Step-by-step explanation:
Hello There!
The area of a sector can be found using this formula
where 0 = angle and r = radius
so given the measures r = 3 and 0 = 50 all we have to do is plug in the values into the formula
so...
so the area of the sector = 1.25π
Note: it says to leave your answer in terms of pi so we do not have to apply pi
N = 30 makes that a perfect square
Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = = = ( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )
BC = ≈ 19.4 cm ( to 3 significant figures )
