The ratio can be written in parts as shown below;

Then, 60 can be divided as shown below;

25kg:35kg
Answer:
Give me more information
Step-by-step explanation:
The parabola defined by
y = a(x - h)² + k
has its vertex at (h,k).
After a shift by h units right, followed by a shift of k units vertically, the parabola is defined by
y = a(x - 2h)² + 2k
which has its vertex at (2h, 2k).
Answer: The vertex gets shifted by h units horizontally and k units vertically.
Answer: The value of x- 2y is a.
.
Step-by-step explanation:
Given: x and y are two positive real numbers such that
and
.
Consider ![(x-2y)^2=x^2-2(x)(2y)+(2y)^2\ \ \ [(a+b)^2=(a^2-2ab+b^2)]](https://tex.z-dn.net/?f=%28x-2y%29%5E2%3Dx%5E2-2%28x%29%282y%29%2B%282y%29%5E2%5C%20%5C%20%5C%20%5B%28a%2Bb%29%5E2%3D%28a%5E2-2ab%2Bb%5E2%29%5D)


Put
and
, we get


Taking square root on both sides , we get'

Hence, the value of x- 2y is a.
