Answer:

$f^{-1}(6) = 50$

Step-by-step explanation:

Given

$f(x) = \sqrt{2x} - 4$

Required

Find $f^{-1}(6)$

First, we calculate the inverse function

$f(x) = \sqrt{2x} - 4$

Express f(x) as y

$y = \sqrt{2x} - 4$

Swap the positions of x and y

$x = \sqrt{2y} - 4$

Solve for y: Add 4 to both sides

$4 + x = \sqrt{2y} - 4+4$

$4 + x = \sqrt{2y}$

Square both sides

$(4 + x)^2 = 2y$

Divide both sides by 2

$y = \frac{(4 + x)^2}{2}$

Express y as an inverse function

$f^{-1}(x) = \frac{(4 + x)^2}{2}$

Next, solve for: $f^{-1}(6)$

Substitute 6 for x

$f^{-1}(6) = \frac{(4 + 6)^2}{2}$

$f^{-1}(6) = \frac{(10)^2}{2}$

$f^{-1}(6) = \frac{100}{2}$

$f^{-1}(6) = 50$

Bonnie is adding a ribbon border to the edge of her kite. Two sides of the kite measure 13.2 inches, while the other two sides m

OLEGan [10]

Answer:

Bonnie needs $67.8\ in$ of ribbon

Step-by-step explanation:

we know that

A Kite is a quadrilateral that has two pairs of equal sides

To find out how much ribbon Bonnie needs calculate the perimeter of the kite

$P=2(L1+L2)$

where

L1 is the length of one side

L2 is the length of the other side

$P=2(13.2+20.7)=67.8\ in$
