Answer:

602.88 cu ft.

Step-by-step explanation:

V = Bh where B is the area of the base, which is a circle in your problem.

Since the diameter is 8, the radius is 4.

So, B = \pi r^{2}  = 3.14(4^{2} )  = 3.14(16) = 50.24

V = Bh = 50.24(20) = 1004.8 cu ft = total volume of tank

60% of that volume is .60(1004.8) = 602.88 cu ft.

ANSWER

\tan( \alpha )  +  \tan( \beta )

EXPLANATION

The given identity is

\frac{  \sin( \alpha  +  \beta ) }{ \cos( \alpha ) \cos( \beta )  }

We expand the numerator to get:

= \frac{  \sin\alpha  \cos\beta  + \sin\beta  \cos \alpha }{ \cos( \alpha ) \cos( \beta )  }

Split the numerator to obtain:

= \frac{  \sin\alpha  \cos\beta }{ \cos( \alpha ) \cos( \beta )  }  + \frac{ \sin\beta  \cos \alpha }{ \cos( \alpha ) \cos( \beta )  }

Cancel the common factors:

= \frac{  \sin\alpha }{ \cos( \alpha )  }  + \frac{ \sin\beta  }{ \cos( \beta )  }

This simplifies to give us;

=  \tan( \alpha )  +  \tan( \beta )

The second choice is correct

WE has a midpoint at K. The coordinates of W are (4,3) and the coordinates of E are (-4,-1). Find the coordinates of K.
Nadusha1986 [10]

Answer:

(0,1)

Step-by-step explanation:

Coordinates of midpoints equal to half of total of 2 endpoints

xK = (xW + xE)/2 = (4 + -4)/2 = 0/2 = 0

yK = (yW + yE)/2 = (3 + -1)/2 = 2/2 = 1

so coordinate of K is (0,1)
