Answer:
Step-by-step explanation:
The following equation represents a straight line that passes through the origin (Point ):
Where "m" is the slope of the line.
In order to find the slope the line, you can use the following formula:
Choose two points on the line. You can choose these points:
You can say that:
Substituting values into the formula, you get that the slope is:
Therefore, the equation of the line is:
The sum of the interior angles of a polygon with n sides is
180(n-2)
A regular octagon has n = 8 (8 equal sides).
The sum of the interior angles is
180*(8 - 2) = 1080°
Because we have a regular octagon, each interior angle is
1080/8 = 135°
The sum of the angles on one side of a straight line is 180°. Therefore the measure of an exterior angle of the regular octagon is 180 - 135 = 45°
Answer: 45°
139° 10′ This is degree minutes. Convert the minutes to decimal by dividing the minutes by 60.
10/60 = 0.167
So 139° 10′ = 139.167 degrees.
Now convert to radians:
139.167 x pi/180 = 2.429 radians
The answer may be slightly different depending on the rounding of everything.
Answer: 7 cars
Step-by-step explanation: Since he earned 400$ a week and he had 1450$ by the end, subtract 1450-400 and you get 1050. You then divide 1050 by 150 (1050÷150) and you get 7, so he sold 7 cars
Answer:2n + 3
