A because polygons have a closed pane
Answer: 888,000
Step-by-step explanation:
Base: 600 x 600 = 360,000
600 x 440 x 2 (there is 4 triangles and 2 makes 1 square. So there is 2 pairs so times 2)= 528,000
360,000 + 528,000= 888,000
Answer:
3.50h + 17
4.75h + 11
Step-by-step explanation:
3.50 per hour times the hours, h, plus the fee, 17
4.75 per hour times the hours, h, plus the fee, 11
In the future, please post the full problem with all included instructions. After doing a quick internet search, I found your problem listed somewhere else. It mentions two parts (a) and (b)
Part (a) asked for the equation of the line in y = mx+b form
That would be y = -2x+9
This is because each time y goes down by 2, x goes up by 1. We have slope = rise/run = -2/1 = -2. This indicates that the height of the candle decreases by 2 inches per hour. The slope represents the rate of change.
The initial height of the candle is the y intercept b value. So we have m = -2 and b = 9 lead us from y = mx+b to y = -2x+9
----------------------------------------------------------------
Part (b) then asks you to graph the equation. Because this is a linear equation, it produces a straight line. We only need 2 points at minimum to graph any line. Let's plot (0,9) and (1,7) on the same xy grid. These two points are the first two rows of the table. Plot those two points and draw a straight line through them. The graph is below
Answer:
The numbers in the second row of each collumn is increasing by 4 every time the numbers in the first row increase by 1.
