Answer: In mathematics, a function is any expression that produces exactly one answer for any given number that you give it. The input is the number you feed into the expression, and the output is what you get after the look-up work or calculations are finished.
Step-by-step explanation:
Answer:
B: 3
Step-by-step explanation:
For the line to be parrallel to the x-axis, it means the slope is zero.
Thus;
(y2 - y1)/(x2 - x1) = 0
(4k - 5 - (2k + 1))/(8 - 3) = 0
4k - 5 - 2k - 1 = 0
2k - 6 = 0
2k = 6
k = 6/2
k = 3
Because the distance to both chords are the same (5.70) and both chords are 90 degrees from the 5.70 line, both chords are identical.
Chord AB = 5, so chord CD is also 5.
91000
when it says nearest ten you ignore the decimals and look at 90998 the nearest ten of 998 is 1000 so keep the nine at the beginning and you have 91000
