kolezko [41]

Answer:

first option

Step-by-step explanation:

Given

y = 2(x - 3)² + 1

Rearrange making x the subject

Subtract 1 from both sides

y - 1 = 2(x - 3)² ( divide both sides by 2 )

\sqrt{\frac{y-1}{2} } = (x - 3)² ( take the square root of both sides )

± \sqrt{\frac{y-1}{2} } = x - 3 ( add 3 to both sides )

± \sqrt{\frac{y-1}{2} } + 3 = x

Change y into terms of x with x being the inverse, that is

f^{-1} (x) = ±\sqrt{\frac{x-1}{2} } + 3

The length of a rectangular floor is two ft more than its width. If the area of the floor is 63 ft, find the length and the widt
NemiM [27]

Answer:

width = 7 and length = 9

Step-by-step explanation:

Let's assume width = w, and length = 2 + w

So area of a rectangle = width * length

63 ft² = w (2 + w)

63 = 2w + w²

w² + 2w - 63 = 0

Use the quadratic formula to solve this

here, a = 1, b = 2 and c = -63

w = 7 or -9

The dimensions of a rectangle cannot be negative. So we take the dimension, w = 7.

Width = 7 and Length = 7+2 = 9
