using the graph of f(x)=1/× as a guide describe the transformation and graph the function g(x)=2/x+4​
Stells [14]

Answer:    

A transformed function of f(x) is defined as,

g(x) = k f(x+a) + b,

Where k shows the stretch or compression ( When |k| > 1 or 0 < |k| < 1 ),

a shows the horizontal shifting, ( When a > 0 then it is shifted left when a < 0 then it is shifted right)

b shows the vertical shifting. ( b > 0 then it is shifted up b < 0 then it is shifted down)

Here, the parent function is,

f(x) = \frac{1}{x}

And, transformed function is,

g(x) = \frac{2}{x+4}= 2f(x+4)

Thus, by the above explanation,

g(x) is obtained after shifting of f(x) horizontally left by 4 unit and after stretched by 2 unit.

In a 30cm by 25cm rectangle, a quadrant of a circle of radius 7cm has been cut away from each corner. What is the perimeter of t
lidiya [134]

Answer:

Perimeter = 98 cm

Area = 596 cm^{2}

Step-by-step explanation:

Please refer to the attached image for the resultant figure when a quadrant of circle with radius 7 cm is cut from a rectangle of sides 30 cm and 25 cm.

Perimeter of a figure = Sum of all its sides + Perimeter of circle

Quadrant of a circle is one fourth of a circle and there are 4 such quadrant of a circle, so eventually there is one complete circle in this figure.

The sides of this resultant figure = 30 - 14 = 16 cm

and 25 - 14 = 11 cm

So perimeter of this figure = 16 + 11 + 16 + 11 + Perimeter of circle

\Rightarrow 54 + 2 \pi r\\\Rightarrow 54 + 2 \times \dfrac{22}{7} \times 7\\\Rightarrow 54 + 44 = 98 cm

To find area of this figure = Area of rectangle - Area of circle

Area of rectangle = Length \times Width

\Rightarrow 30 \times 25 = 750\ cm^{2}

Area of circle = \pi r^{2}

\Rightarrow \dfrac{22}{7} \times 7^{2} = 154\ cm^{2}

So, area of figure = 750 - 154 = 596 cm^{2}
