The first three terms in the binomial expansion of (a+b)^n in ascending powers of b, are p,q and r respectively. show that q^2/p
katen-ka-za [31]

First 3 terms are a^2 + n a^(n-)1 b + n(n-1)/2 * a^(n-2) b^2


So q^2 / pr = (n^2 * a^(2n-2) * b^2 ) / (1/2 * a^n * (n(n-1) * a^(n-2) * b^2 )


= n^2 * a^2n-2 * b^2

-----------------------------------

1/2 n(n-1) * a^(2n-2) * b^2


= 2n / n - 1 as required


given p = 4, q=32 and r = 96:-


32^2 / 4*96 = 2n / n-1

2n / n-1 = 8/3

6n = 8n - 8

2n = 8


n = 4 answer

Please help and thank you!!

The correct answer is A) f(x) should be vertically stretched by 1.5.

This is because it is going to be rising at a much faster rate. Therefore, the slope should be more steep, which can only be done by stretching the graph. Moving it up and down would only change the initial amount she had traveled, which should always be 0.
