Answer:
-x^2-x+2
Step by step explanation:
(x^2+1)-(2x^2+x-1)
x^2+1-(2x^2+x-1)
x^2+1-2x^2-x+1
-x^2+1-x+1
-x^2+2-x
-x^2-x+2
Answer: The radius is half the diameter and the diameter is double the radius
Step-by-step explanation:
The diameter is a straight line across the center of a circle. It goes from one side to another. The radius is half that, so a line starting from the center that goes to just one side.

Answer:
112.34
Step-by-step explanation:
The 2nd digit after the decimal point is in the hundredths position.
• If the digit following is ≥ 5 then round up
• If the digit following is < 5 then leave digit as it is
here the digit following the 3 in the hundredths position is 9 so round up
112.3398 ≈ 112.34 ( to the nearest hundredth )
Prob(there are no sixes after the roll) = (5/6)^4 = 625/1296
Prob( at least on six is rolled) = 1 - 625/1296 = 671/1296 = 0.518 to nearest 1/1000
