expeople1 [14]

Answer:

A. 51°

Step-by-step explanation:

By the theorem of intersecting secants.

m\angle B=\frac{1}{2} (m\widehat{LW} - m\widehat{MU})

44.5\degree =\frac{1}{2} (140\degree - m\widehat{MU})

2\times 44.5\degree = 140\degree - m\widehat{MU}

89\degree = 140\degree - m\widehat{MU}

m\widehat{MU} = 140\degree -89\degree

m\widehat{MU} = 51\degree

What is the inverse of f(x) = sqft x+ 3
grin007 [14]

Answer:

f^{-1} (x)=x^{2} -3

Step-by-step explanation:

Given the function

f\left(x\right)=\sqrt{x+3}

We can find the inverse function by exchanging x and y, and then solve for y.

y=\sqrt{x+3}

Replace x with y.

x=\sqrt{y+3}

square both sides

x^2=y+3

y=x^2-3

Hence,

f^{-1} (x)=x^{2} -3
