weeeeeb [17]

Answer:

Hello,

Step-by-step explanation:

f(x)=\dfrac{4}{x} \\\\g(x)=\dfrac{4}{x} \\\\\\(gof)(x)=f(g(x))=f(\dfrac{4}{x} )=\dfrac{4}{\dfrac{4}{x} } =\dfrac{4*x}{4} =x\\\\\\(fog)(x)=g(f(x))=g(\dfrac{4}{x} )=\dfrac{4}{\dfrac{4}{x} } =\dfrac{4*x}{4} =x\\

Find the first five term of the sequence whose nth term is given by the fallowing-4n-3
Korvikt [17]

a(1) = -4(1)-3 = -4-3 = -7

a(2) = -4(2)-3 = -8-3 = -11

a(3) = -4(3)-3 = -12-3 = -15

a(4) = -4(4)-3 = -16-3 = -19

a(5) = -4(5)-3 = -20-3 = -23

So, sequence would be -7,-11,-15,-19,-23

The equation of a circle whose center is at (1,2) and radius is 5 is (x + 1)² + (y + 2)² = 5 (x - 1)² + (y - 2)² = 25 (x - 1)² -
Oksana_A [137]
\bf \textit{equation of a circle}\\\\ 
(x- h)^2+(y- k)^2= r^2
\qquad 
center~~(\stackrel{1}{ h},\stackrel{2}{ k})\qquad \qquad 
radius=\stackrel{5}{ r}
\\\\\\\
(x-1)^2+(y-2)^2=5^2\implies (x-1)^2+(y-2)^2=25
