The error is that if the absolute value your looking for is a positive number, you wouldn't have to change and the sign.
Answer:
10%
Step-by-step explanation:
Answer:
x² + (y-74)² = 4900
Step-by-step explanation:
Circle equation: (x-h)² + (y-k)² = r²
"h" refers to horizontal shifts while "k" refers to vertical shifts. If the center of the wheel is directly above the origin of the rectangular plane and the entire wheel is 4 ft. from the ground then:
- h = 0
- k = 74 (the radius + 4 ft.)
- r = 70
So plugging those into the equation of circles, we get the answer above.
Answer:
h < 100
Step-by-step explanation:
isolate h by dividing both sides by 2
h < 100
