Presumably you want to find
, where
presumably denotes the complement of
. We have
and since
, we have
the set of all values in
*not* in
; that is,
.
Now
Use grouping to factor the numerator (top):
x^4 - 2x³ -x + 2
x³(x-2) -1(x-2)
=(x³-1)(x-2)
Cancel the (x³-1) factor from the numerator and denominator leaves (x-2).
Answer: B
Answer:
A. 32.08
Step-by-step explanation:
The figure given is a right triangle. We would apply trigonometric ratios formula to find x.
Reference angle = 58°
Hypotenuse = x
Adjacent length = 17
Thus, we would apply the following:
Plug in the values
Multiply both sides by x
Divide both sides by Cos(58)

Answer:
The player should receive 3 times as many points.
Step-by-step explanation:
Ratio of the points should be the same as ratio of the areas
(Ratio of radii)² = Ratio of areas
= (4/2)² = 2² = 4
The ratio of the areas:
inner circle to the outer ring is:
1 : 4-1
1 : 3
