Answer:

36.4 m

Step-by-step explanation:

Rounded to tenths, the dimensions are ...

12.7 m by 5.5 m

The sum of these is 18.2 m, so the estimate of the perimeter is ...

2·18.2 = 36.4 m

_____

The perimeter formula is ...

P = 2(L +W) . . . . . twice the sum of length and width.

Answer:

$\boxed{\sf \ \ \ f^{-1}(x)=1+\sqrt{x} \ \ \ }$

Step-by-step explanation:

the minimum of f is for x = 1 and f(1)=0

f is decreasing for x<=1 and increasing for x>=1

so the domain is $[1;+\infty[$

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

x>=1 so x is positive and we can take the square root

so $f^{-1}(x)=1+\sqrt{x}$

Slope 4.2; y-intercept (0,3.4)

umka2103 [35]

Answer:I don't know if you're asking for equation or not cause you didn't mention the question so I'm just gonna write down the equation.

y=4.2x+3.4

Use this formula➡️y=mx+b

m is slope, b is y-intercept , x and y are the points like (0, 3.4)

You said it's the y-intercept but it's not. it's just a point on the graph
