What is the inverse of g? <br> g(x) = 3/x+7
ikadub [295]

Given function :-

\bf \implies g(x) = \dfrac{3}{x}+7

  • To find its reverse , substitute y = g(x) .

\bf \implies y = \dfrac{3}{x}+7

  • Interchange x and y .

\bf \implies x = \dfrac{3}{y}+7

  • Solve for y .

\bf\implies \dfrac{3}{y}= x -7 \\\\\bf\implies y =\dfrac{3}{x-7}

  • Replace y with f-¹(x) .

\implies\boxed{\red{\bf f^{-1}(x) = \dfrac{3}{x-7} }}

A rectangle has an area of 524.4m2. One of the sides is 6.9m in length. Work out the perimeter of the rectangle. PLEASE ANSWER!!
malfutka [58]

Answer:

<h2>165.8 m</h2>

Solution,

Area of rectangle= 524.4 m^2

Length(L)= 6.9 m

Breadth(B)=?

Now,

area = length  \times breadth \\ or \: 524.4 = 6.9 \times b \\ or \: 524.4 = 6.9b \\ or \: b =  \frac{524.4}{6.9}  \\ b = 76 \: m

Again,

Perimeter of rectangle:

2(l + b) \\  = 2(6.9 + 76) \\  = 2 \times 82.9 \\  = 165.8 \: m

Hope this helps...

Good luck on your assignment.....
