Answer:
The roller coaster is 155 feet above the ground.
Step-by-step explanation:
Given:
The roller coaster climbs 120 feet from ground level.
Then drops 75 feet
Then again climbs 105 feet
To find distance of roller coaster above the ground now we will subtract the drop in level from the rise and then add the second rise to the difference.
This can be evaluated as:
⇒ 
⇒ 
Thus the roller coaster is 155 feet above the ground.
Answer with explanation:
Properties of Rectangle
1. Opposite sides are equal and parallel.
2. Diagonals are equal and bisect each other.
3. Adjacent Sides are Perpendicular to each other.
→If two lines are parallel their slopes are equal and if two Lines are perpendicular, their product of slopes is -1.
→A Rectangle is a Quadrilateral also.
→Adjacent sides are perpendicular ,so , their slopes can't be equal.Product of their slopes should be equal to ,-1.
⇒Slope of AB × Slope of BC = -1
⇒Also, Slope of AB × Slope of BC = -1
Slope of AB × Slope of AD = -1
⇒ Slope of AD × Slope of CD = -1
Slope of CB × Slope of CD = -1
Option B And Option C
are statement which proves that polygon ABCD is not a rectangle.
Answer:
Approximately 62.83 inches.
Exactly 20π inches.
Step-by-step explanation:
It's simply the wheel's circumference.
<em>C</em> = 2π<em>r</em> = 2(10)(π) = 20π ≈ 62.83 inches
