Answer:
Therefore the angle of intersection is
Step-by-step explanation:
Angle at the intersection point of two carve is the angle of the tangents at that point.
Given,
and
To find the tangent of a carve , we have to differentiate the carve.
The tangent at (0,0,0) is [ since the intersection point is (0,0,0)]
[ putting t= 0]
Again,
The tangent at (0,0,0) is
[ putting t= 0]
If θ is angle between tangent, then
Therefore the angle of intersection is .
8 litres (amount of 20% solution needed) and 7 litres for (amount of 50% solution needed)
<u>Step-by-step explanation:</u>
Let consider ‘x’ for 20% acid solution and (15 – x) for 50% acid solution. And so, the equation would be as below,
20% in x + 50% in (15 – x) = 15 litres of 34%
Convert percentage values, we get
0.20(x) + 0.50 (15 – x) = 15 (0.34)
0.20 x + 7.5 – 0.50 x = 5.1
-0.3 x + 7.5 = 5.1
0.3 x = 7.5 – 5.1
0.3 x = 2.4
Apply ‘x = 8’ value in (15 – x) we get,
15 – 8 = 7 litres
The value of 7 litres for (amount of 50% solution needed)
