Hello,
A function f(x) is even if f(-x)=f(x).
A: (x-1)²+1≠((-x)-1)²+1
B:2x²+1=2(-x)²+1 is even
C:4x+2≠4*(-x)+2
D:2x≠2*(-x)
Answer B
Hey there! :)
The formula for finding volume of a sphere = 4/3 · π · r³
Radius = 1
1³ = 1 × 1 × 1 = 1
π = 3
3 × 1 = 3
3 × 4/3 = 12/3 = 4
The volume is 4 in³
Hope this helps :)

Step-by-step explanation:
Answer:
(a) 0.0001 or 0.01%
(b) 0.01 or 1%

Since there are 10 possible numeric digits (from 0 to 9), and there is only one correct digit, there is a 1 in 10 change of getting each digit right.
The probability that if you forget your PIN, then you can guess the correct sequence
(a) at random:

(b) when you recall the first two digits.

Hello,
x²+2*7x+49+y²+2y+1+14-49-1=0
==>(x+7)²+(y+1)²=36
Center is (-7,-1) and radius 6.
