Answer:
Two distinct concentric circles: 0 max solutions
Two distinct parabolas: 4 max solutions
A line and a circle: 2 max solution
A parabola and a circle: 4 max solutions
Step-by-step explanation:
<u>Two distinct concentric circles:</u>
The maximum number of solutions (intersections points) 2 distinct circles can have is 0. You can see an example of it in the first picture attached. The two circles are shown side to side for clarity, but when they will be concentric, they will have same center and they will be superimposed. So there can be ZERO max solutions for that.
<u>Two distinct parabolas:</u>
The maximum solutions (intersection points) 2 distinct parabolas can have is 4. This is shown in the second picture attached. <em>This occurs when two parabolas and in perpendicular orientation to each other. </em>
<u>A line and a circle:</u>
The maximum solutions (intersection points) a line and a circle can have is 2. See an example in the third picture attached.
<u>A parabola and a circle:</u>
The maximum solutions (intersection points) a parabola and a circle can have is 4. If the parabola is <em>compressed enough than the diameter of the circle</em>, there can be max 4 intersection points. See the fourth picture attached as an example.
Answer:
x=y
Step-by-step explanation:
There is exactly one value of x for a value of the function by the one-to-one property.
Answer:
100 percent increase
Step-by-step explanation:
1st garden
Length = 6 ft
Width = 4 ft
Perimeter = 2 (l+w)
= 2 (6+4) = 2(10) = 20
2nd garden
The length and width are 2 times the 1st garden
Length = 2 *6 = 12
Width = 2 *4 = 8
Perimeter = 2 (l+w)
= 2 (12+8) = 2(20) = 40
Percent change = (new - old )/old * 100 percent
The 1st garden is the old garden = 20 and the 2nd garden is the new garden = 40
Substituting in
Percent change = (40-20)/20 = 20/20 =100 *100 percent
= 100 percent increase
There are 24 (2x8+2x4) posts around the pool with 4 overlaps, therefore, there are 20 posts in total.
Among the 8 posts along one side, there are 7 gaps in between them. Hence, the length is 2x7=14yards
Among the 4 posts on the other side, there are 3 gaps in between them. Hence, the width is 2x3=6 yards
