Answer:
y-x-1 < 0
Step-by-step explanation:
according to the graph (0,1) and (-1,0) lies on the doted line,
equation of the dotted line is y-x-1=0
shaded region = y-x-1 < 0
Answer:
109.9 feet
Step-by-step explanation:
To find how many feet has Miguel traveled, we need to know the circunference of the tire:
C = pi*d = 3.14 * 28 = 87.92 inches
So, for each revolution of the tire, Miguel will travel 87.92 inches. So, to know the distance he will travel, we can do a rule of three:
1 revolution -> 87.92 inches
15 revolutions -> x inches
1/15 = 87.92/x
x = 87.92 * 15 = 1318.8 inches
As the question asks for the distance in feet, we convert from inch to foot by dividing the value of inches by 12, so:
distance in feet = 1318.8 / 12 = 109.9 feet
