Find the 5th term of the expansion of (x + y)^9 a. 81x4y5 c. 81x5y4 b. 126x4y5 d. 126x5y4 select the best answer from the choices provided a b c d

Option d. .

Step-by-step explanation:

Based on binomial theorem we write down the binomial formula for all positive integer values of n as-

Now we calculate the 5th term of

From the given formula the fifth term of the binomial will be

=

Here the value of n = 9

Then the fifth term will be

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

a - base

b - exponent

so,
