Answer:
Step-by-step explanation:
The cost per sandwich when 3 are delivered is $20/3 or $6.67 each.
The cost per sandwich when 4 are delivered is $26/4 or $6.50 each.
The average cost per sandwich changes with the number delivered, so it is not proportional. The cost decreases per sandwich as the volume of sandwiches increases. One can't predict the cost of 6 delivered sandwiches based on the information provided. If it were proportional, the cost could be calculated on the basis of the slope of the line. If all sandwiches cost $6.50 each, regardless of the volume ordered, the slope of a line relating number ordered and total cost would have a constant slope of 6.50. That isn't the case in this problem. The slope keeps changing.
Answer:
A. (3/2)² = (9/4)
B. (-1/2)⁴ = (1/16)
C. (-1/3)³ = 1/81
D. (-4/5)⁰ = 1
E. (-5/9)¹ = (-5/9)
Step-by-step explanation:
A. (3/2)² = (9/4)
(3/2)*(3/2) numerators-<em>3*3=9</em> denominators-<em>2*2=4</em> (9/4)
B. (-1/2)⁴ =
(-1/2)*(-1/2)*(-1/2)*(-1/2)=(-1*-1*-1*-1)/(2*2*2*2)= (1/16)
C. (-1/3)³ =
(-1/3)*(-1/3)*(-1/3)*(-1/3)=(-1*-1*-1*-1)/(3*3*3*3)=(1/81)
D. (-4/5)⁰ =
Anything to the power of 0 is =1
E. (-5/9)¹ =
Anything to the power of one is itself = (-5/9)
So, 260 degrees is in the 3rd quadrant, only 10 degrees away from being straight down at 270 degrees....if you have a xy axis, and draw a line segment from the origin into the 3rd quadrant, then at the endpoint of that segment, draw back up to the x-axis, your reference angle is the angle that the line segment makes with the x-axis (in this case, the negative portion of the x-axis), which is 80 degrees....since 260 degrees is 80 degrees past 180.
So your answer is 80 degrees.
Hope this helps,
