The area of the arrow given in the figure is 610 square cm

<h3>Area of composite figure</h3>

The given figure is made up of rectangle and triangle. The area is expressed as:

Area = Area of rectangle + area of triangle

Substitute the given parameters

Area of the arrow = (15*20) + 0.5(31 * 20)

Area of the arrow = 300 + 310
Area of the arrow = 610 square cm

Hence the area of the arrow given in the figure is 610 square cm

Please help asap find f -1

ExtremeBDS [4]

I.
Given a function f with domain D and range R, and the inverse function
$f ^{-1}$ ,

then the domain of $f ^{-1}$ is the range of f, and the range of $f ^{-1}$ is the domain of f.

II. We are given the function $f(x)= \sqrt{x-5}$ ,

the domain of f, is the set of all x for which $\sqrt{x-5}$ makes sense, so x is any x for which x-5 $\geq$ 0, that is x≥5.

the range is the set of all values that f can take. Since f is a radical function, it never produces negative values, in fact in can produce any value ≥0

Thus the Domain of f is [5, ∞) and the Range is [0, ∞)
then , the Domain of $f ^{-1}$ is [0, ∞) and the Range of $f ^{-1}$ is [5, ∞)

III.
Consider $f(x)= \sqrt{x-5}$

to find the inverse function $f^{-1}$ ,

1. write f(x) as y:

$y= \sqrt{x-5}$

2. write x in terms of y:

$y= \sqrt{x-5}$

take the square of both sides

$y^{2} =x-5$

add 5 to both sides

$y^{2} +5=x$

$x=y^{2} +5$

3. substitute y with x, and x with $f^{-1}(x)$ :

$f^{-1}(x)=x^{2} +5$

These steps can be applied any time we want to find the inverse function.

IV. Answer:

$f^{-1}(x)=x^{2} +5$ , x≥0

y≥0, where y are all the values that $f^{-1}$ can take

A plane, parallel to the base of a cone intersects the cone at the midpoint between points A and B. Determine the area of the cr

IRINA_888 [86]

Given that point of intersection is at halft ot the heigth, by similarity of triangles, the radius is halft of 6 in, i.e 3 in.

The the area is Pi*r^2 = Pi*(3in)^2 = Pi*9 in^2 = 9Piin^2

This is option C)
