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 :)

Si f(x) = 1/2x^2-(1/4x+3),¿cuál es el valor de f(8)?<br> (3) 27<br> (2) 17<br> (4) 33<br> (1) 11
gavmur [86]

Answer:

27

Step-by-step explanation:

To evaluate f(8) substitute x = 8 into f(x)

f(8) = \frac{1}{2} × 8² - (\frac{1}{4} × 8 + 3)

     = \frac{1}{2} × 64 - (2 + 3)

     = 32 - 5

     = 27
