What’s the inverse of y= 100 - x^2
Marianna [84]

Answer:

The inverse is ±sqrt(100-x)

Step-by-step explanation:

y= 100 - x^2

Exchange x and y

x = 100 -y^2

Solve for y

Subtract 100 from each side

x-100 = 100-100-y^2

x-100 = - y^2

Multiply by -1

-x+100 = y^2

100 -x = y^2

Take the square root of each side

±sqrt(100-x) = sqrt(y^2)

±sqrt(100-x) = y

The inverse is ±sqrt(100-x)

The diagonal of a square has a length of Eight times begin square root two end square root cm. Find the length of a side of the
Sidana [21]

ANSWER

A. 8cm

EXPLANATION

The diagonal of the square is

d = 8 \sqrt{2} cm

Let the length of each side of the square be l units.

Then the diagonal and any two sides form an isosceles right triangle with the diagonal being the hypotenuse.

We use the Pythagoras Theorem, to obtain,

{l}^{2}  +  {l}^{2}  =  {d}^{2}

This implies that,

2 {l}^{2}  = (8 \sqrt{2}  )^{2}

2{l}^{2}  = 128

Solve for l,

{l}^{2}  = 64

Take positive square root of both sides

l =  \sqrt{64}

l = 8cm
