The radius is 1.75 and the approximate circumference is 10.5 the pi circumference is 5.495 pi
the answer would be 23 because 46 and 2 are both common factors of 23.
1, it is one because .99 divided by 6475 is 0.1528, and 0.1528 to nearest whole number is 1.
1 is your answer.
The answer I believe is b
Step-by-step explanation:
Root of the function, where y = 0
f(x) = x² + 2x - 1
0 = x² + 2x - 1
x² + 2x - 1 = 0
x² + 2x = 1
x² + 2x + 1 = 1 + 1
(x + 1)² = 2
x + 1 = ±√2
x = -1 ± √2
Roots → x = -1 ± √2
