Find the volume of a trough 5 meters long whose ends are equilateral triangles, each of whose

yawa3891 [41]

Answer:

$V=5\sqrt{3}\ m^3$

Step-by-step explanation:

we know that

The volume of a trough is equal to

$V=BL$

where

B is the area of equilateral triangle

L is the length of a trough

step 1

Find the area of equilateral triangle B

The area of a equilateral triangle applying the law of sines is equal to

$B=\frac{1}{2} b^{2} sin(60\°)$

where

$b=2\ m$

$sin(60\°)=\frac{\sqrt{3}}{2}$

substitute

$B=\frac{1}{2}(2)^{2} (\frac{\sqrt{3}}{2})$

$B=\sqrt{3}\ m^{2}$

step 2

Find the volume of a trough

$V=BL$

we have

$B=\sqrt{3}\ m^{2}$

$L=5\ m$

substitute

$V=(\sqrt{3})(5)$

$V=5\sqrt{3}\ m^3$

Which expression represents the area of the figure?

lys-0071 [83]

Answer:

The solution is 8x2 + 16x + 8. The region can be divided into a triangle and a rectangle.

Area of Triangle=

(2x + 2)(2x)

Area of Triangle = 2x2 + 2x

Area of Rectangle: (2x + 2)(3x + 4)

Area of Rectangle: 6x2 + 14x + 8

Sum of Two Regions: 8x2 + 16x + 8
