Answer:
maximum difference of radii =
Step-by-step explanation:
We know that area of circle is given by

For circle with radius 'r' we have

For circle with radius 'R' we have

Now according to given condition we have


Thus maximum difference of radii =
Answer:
z to the power of 4 x squared square root of yx
1. The intevals of x should be:
because point (-1,1) lies on the linear part of the graph;
because the point (-1,1) doesn't lie on the first parabola;
This gives you that option B is false.
Now the middle part of the graph is parabola going in negative y-direction and right part of the graph is parabola going in positive y-direction. Therefore, option A is false, because there the middle parabola is going upward.
The third part of the graph has vertex at point (5,4). In option D the vertex of the parabola is (3,4), so this option is false.
Answer: correct choice is C.
1) answer = 360
explanation =
-> 10% of 300 = 300*10
-> 10% of 300 = 30
-> 20% = 10% x 2
-> 20% = 30 x 2
-> 20% = 60
-> 300 yards ( distance they ran ) + 60 yards ( how much more distance Quadra ran ) = 360 yards
2) answer = Newton spends 10 minutes or 1/6 hours reading
explanation =
-> 25% = 1/4
-> 40*4= 10
-> 1 hrs = 60 min
-> 10 min x 6 = 60 min
-> 1/6 hrs = 10 min
3) answer = 30 fish
explanation =
-> 40% = 12
-> 10% = 3
-> 40*4=10 and 12*4=3
-> 10% + 40% = 50% so 12 + 3 = 15
-> 50% = 15 and 100% = 15 x 2
-> 100% = 30
4) answer = 30
explanation =
-> 1/4 is equal to 25 %
-> add up all the prrcentages ( 25% + 10% + 15% = 50% )
-> she have 50% of tej chocolates Which were in the tin she bought away and kept 15 chocolates to herself
-> 50% = 1/2
-> 50% x 2 = 100%
-> 15 x 2 = 30
