U need help ASP .<br>f(x)=1-3X and g (x)=x+4 calculate gf(-2)<br>

IgorC [24]

Answer:

gf (-2) = 11

Step-by-step explanation:

$f(x) = 1 - 3x \\ g(x) = x + 4 \\ gf( - 2) = ..$

$gf = .. \\ g(1 - 3x) \\ = 1 - 3x + 4 \\ = - 3x + 5 \\ gf = - 3x + 5$

$gf( - 2) = - 3( - 2) + 5 \\ = 6 + 5 = 11$

What is the second term in the binomial expansion of (2r-3s)12?

Reptile [31]

$(a+b)^n=\displaystyle\sum_{k=0}^n\binom nka^{n-k}b^k$

where $\dbinom nk=\dfrac{n!}{k!(n-k)!}$ . The second term of the expansion occurs when $k=1$ .

So the second term of the expansion of $(2r-3s)^{12}$ is

$\dbinom{12}1(2r)^{12-1}(-3s)^1=12(2r)^{11}(-3s)=-73728r^{11}s$
