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)
Answer:
8
Step-by-step explanation:
To find the answer, multiply 4 and 2 together, since 13 is 2 times less than 26.
----------------------------------------------------------------------------------------------------------------
Let's double check,
26 ÷ 13 = 2
so,
4 × 2 = 8

Have a good day :)
Answer: -7
In the slope-intercept format y = mx+b, b is always the y-intercept. If it is with a positive sign, the y-intercept is positive and if it is negative then the y-intercept is negative.
