Answer:

V = 13312yd^2

Step-by-step explanation:

32 x 32 x 39 / 3 = volume

32 x 32 x 39 = 39936/3 = 13312 sq yard.

As you can see the formula for Volume is L x W x H / 3

The formula for Area of a pyramid is SA = A + (3/2)bh

We have one rule we work out the square to represent the A then we can find SA. While 3/2 is 1.5 really which is 150% of the height x the base, then we + plus the area of the square.

Find the equation of a straight line that has a perpendicular bisector of AB.

Natalija [7]

Answer:

Step-by-step explanation:

slope of line through A ,B is

m=(-2-6)/(5-2)=-8/3

slope of line perpendicular to AB Is 3/8

mid-point of AB =((2+5)/2,(6-2)/2)=(7/2,2)

eq. of reqd line is

y-2=3/8(x-7/2)

8y-16=3x-21/2

16y-32=6x-21

16y-6x=-21+32

16y-6x=11

Sum and difference tan(135+30)

Mumz [18]

$\tan(x+y)=\dfrac{\sin(x+y)}{\cos(x+y)}=\dfrac{\sin x\cos y+\sin y\cos x}{\cos x\cos y-\sin x\sin y}=\dfrac{\tan x+\tan y}{1-\tan x\tan y}$

So,

$\tan(135^\circ+30^\circ)=\dfrac{\tan135^\circ+\tan30^\circ}{1-\tan135^\circ\tan30^\circ}$

You should know that $\tan135^\circ=-1$ and $\tan30^\circ=\dfrac1{\sqrt3}$

Putting everything together,

$\tan(135^\circ+30^\circ)=\dfrac{-1+\dfrac1{\sqrt3}}{1-(-1)\left(\dfrac1{\sqrt3}\right)}=\dfrac{1-\sqrt3}{\sqrt3+1}=\sqrt3-2$
