ik im not first but have a lovely day! u are really kind! never forget that!
Given:
Line A: 
Line B: 
Line C: 
Line D: 
To find:
Which lines are perpendicular
Solution:
General equation of a line:
y = mx + c
where m is the slope and c is the y-intercept.
Slope of line A = 
Slope of line B = 
Slope of line C = 2
Slope of line D =
<em>Two lines are perpendicular if their slopes are negative reciprocal of one another.</em>
Negative reciprocal of is 2.
Therefore line B and line C are perpendicular lines.
The equation for momentum is p =
mv where p is the momentum, m is the mass and v is the velocity. Calculating
the momentum for each football player, player A will have a momentum of 1050
lb-mi/h and player B will have a momentum of 570 lb-mi/h. Therefore, momentum of player A is greater than that of
player B.
Answer:
u might need to reword that buddy
Step-by-step explanation:
1 min = 40 words
1 page = 500
It would take Regina 250 minutes to type 20 pages because we would first divide 500 words by 40 words (40 words equaling 1 minute) to first find out how long it took her to type 1 page. After finding it was 12.5 mins we then multiple, 12.5 x 20 which gives us 250 minutes. Which is also 4 hours and 10 minutes I believe.
