20x = 2*100
x = 10 ml (amt of 30% solution needed)
100-x = 90 ml (amt of 10% solution needed)
Very hard but I hope it helps
Answer:
no se pregúntale a otro gracias cuidate mucho:)
We know that
A range value of 3 that means
that the value of y is 3
<span>observing the table we see that for y = 3 the value of x is 0
therefore
the value of the domain for the range 3 is 0
the answer is
0

Answer:
Step-by-step explanation:
Parameterize the ellipse as (acos∙,bsin∙). Take points P:=(acosp,bsinp) and Q:=(acosq,bsinq) on the ellipse, with midpoint M:=(P+Q)/2.
If |PQ|=2k, then
a2(cosp−cosq)2+b2(sinp−sinq)2=4k2
The coordinates of M are
xy==a2(cosp+cosq)b2(sinp+sinq)
