5 liters of water must be added.
Step-by-step explanation:
In this question form and equate equations for the amount of sugar in both syrups which does not change.
Let the amount of water to be added to 15 liters of 40% sugar syrup to be w liters
The 40% sugar syrup will contain 15 liters of 40% sugar syrup. This means that the amount of sugar contained in the syrup is 15 *0.4 = 6 liters......(i)
So for a 30% sugar syrup, the amount of syrup is =15 +w *L , thus amount of sugar in this syrup will be : (15+w)0.3*L--------(ii)
Because only water was added, the amount of sugar remains the same hence equate the equations for amount of sugar;
0.3(15+w)=6
solve for value of w as
4.5+0.3 w =6
0.3 w = 6-4.5
0.3 w = 1.5
w= 1.5/0.3 = 5 liters

Answer:
(x+1)2+(y−2)2=5
Explanation:
The general form for a circle with center
(a,b) and radius r is XXX(x−a)2+(y−b)2=r2
With center (−1,2) and given that (0,0) is a solution (i.e. a point on the circle),according to the Pythagorean Theorem: XXX r 2=(−1−0)2+(2−0)2=5
and since the center is (a,b)=(−1,2)by applying the general formula we get:XXX(x+1)+(y−2)2=5
