Answer:
Concept: Mathematical Sequences
- Let An be 99 a double digit multiple
- The sequence is finite.
- Finite= restricted and not bounded to positive infinity
- By that logic the last possible digit is 999999999999999999999999999999999999999999999
Answer:
62 degrees
Step-by-step explanation:
- Its key to copying a specified line is to open your beacon to the length of both the section, then use that amount of entrance to label off another section of the same length.
- To bisect a segment or angle means to divide it into confocal scanning parts. A line segment's bisector would then pass thru the midpoint of its segment.
- Once copying a segment as well as bisecting a section, its Draw a ray including one end-point step will be the same.
- So if copying a line and bisecting a line segment, this same needle of both the compass is placed mostly on-line segment's end.
- Therefore, the "Draw a ray with one endpoint" choices are correct, and the other choices were incorrect.

Step-by-step explanation:
<h3>Given</h3>
- (x +
)(y + 
) = 1 - (x+y)² = ?
<h3>Solution</h3>
<u>Let's make substitution as:</u>
- (x + ) = m
then
- (y + ) = 1/m
<u>Solving the first equation for x and the second one for y:</u>
- (x + ) = m
- = m - x
- 1 + x² = (m - x)²
- 1 + x² = m² - 2mx + x²
- 2mx = m² - 1
- x = (m² - 1)/2m
And
- (y + ) = 1/m
- = 1/m - y
- 1 + y² = 1/m² -2y/m + y²
- 1 = 1/m² - 2y/m
- m² = 1 - 2my
- 2my = 1 - m²
- y = (1 - m²)/2m
- y = - (m² - 1)/2m
<u>Now, sum of x and y:</u>
- x + y = (m² - 1)/2m - (m² - 1)/2m = 0
<u>Therefore:</u>
Answer is zero
