Answer:
Step-by-step explanation:
Left Panel
Angles with a positive measure all go anticlockwise if that is still taught. An example of that is the top one on the left panel. That's the counterclockwise direction. A and C are both going anticlockwise so they are going in the plus direction. (You are still in the left panel). The middle one is going clockwise so it is minus.
Central Panel
Top is clockwise so it is minus
Middle is counterclockwise so it is plus
I don't want to make a guess, but the third one is clockwise and minus.
Right Panel
The top one is anticlockwise so it is plus
The second one is clockwise, so it is minus
Answer:
2 what?
Step-by-step explanation:
Answer:
a
Step-by-step explanation:
This is the sum of the arithmetic sequence:
10 - 2 + 6 + 14 + ... + 110
where: a 1 = - 10, d = 8
a n = 110
a n = a 1 + ( n - 1 ) * d
110 = - 10 + ( n - 1 ) * 8
110 = - 10 + 8 n - 8
110 + 10 + 8 = 8 n
128 = 8 n
n = 128 : 8
n = 16
∑ n = n/2 * ( a 1 + a n )
∑ 16 = 16/2 * ( -10 + 110 ) = 8 * 100 = 800
Answer:
The sum is 800.
B is not proportional because it does not go thru the origin
