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
Answer:
B
Step-by-step explanation:
5.7 is five and 7 tenths and you keep moving up
You get: (1x20)/(5x20)=20/100=20%.
Hope i helped you! :)
700 + 80 + 2^2?
I have no idea rly lol
The <u>whole number</u> <u>closest </u>to √22 is 5.
The square root of 22 is:
= √22
= 4.69
The whole number that it is closest to will <u>depend on the first decimal point</u>.
If it is 5 or above then it will be closest to 5.
If it is 4 and below, then it is closest to 4.
The first decimal point is 6 so √22 is closer to 5.
In conclusion, the square root of 22 is closer to 5.
