Given the quadrilateral is a rectangle, if LO = 15x+19 and QN = 10x+2 find PN
see the attached figure to better understand the problem
we know that
The diagonals of a rectangle are congruent and bisect each other
so

substitute the given values

solve for x

Find the length of PN
Remember that
----> diagonals of rectangle are congruent

substitute the value of x

therefore

Answer:
A circle can intersect a parabola in
1. One point [ when circle just touches the parabola]
2. Two points [ When circle cuts the parabola in two distinct points. ]
3. Three points [Circle just touches at one point and cuts the parabola in two distinct points]
4. Four points [ Either parabola or circle meeting each other or crossing at four distinct points]
Answer:
approximately 14 each hour
Step-by-step explanation:
500/100 = 5 = 1% of 500
2% of 500 = 10
500 - 10 = 490
490/36 = 13.6 or about 14
multiply 14 by the number of hours each day and you'll get the final answer
