The surface area of the three-dimensional figure is square centimeters?

Zina [86]

Answer:

Step-by-step explanation:

Alright, lets get started.

The surface area of the figure given is : The area of all shapes together

The figure has 2 similar triangles and 3 similar rectangles.

The area of 1 triangle =

$\frac{1}{2}*base*height$

The area of 1 triangle = $\frac{1}{2}*10*8.66=43.3$

So, the area of both triangles = $43.3*2=86.6$

The area of 1 rectangle = $width *length$

The of 1 rectangle = $10*15=150$

So, the area of all 3 rectangles = $3*150=450$

So, total area of figure = $86.6+450=536.6$

hence the surface area is 536.6 square centimeters : Answer

Hope it will help :)

Determine the domain of the function (f*g)(x) where f(x) =3x-1/x-4 and g(x) =x+1/x

BARSIC [14]

Answer:

Domain = R- {0,4}

Step-by-step explanation:

$f(x) =\frac{3x-1}{x-4}$

$g(x) =\frac{x+1}{x}$

$(f*g)(x)=\frac{3x-1}{x-4} \times \frac{x+1}{x}$

$(f*g)(x)=\frac{(3x-1)(x+1)}{(x-4)(x)}$

In order to function (f*g)x to be defined , the Denominator must not be equal to zero.

Hence

x ≠ 0

(x-4) ≠ 0 ⇒ x≠4

Hence (f*g)x is defined for all values of x except 0 and 4

Hence Domain = R- {0,4}
