What is the lateral area of the drawing?
katrin2010 [14]

The lateral area of the shape is the sum of the area of all lateral faces.

The area of the lateral face that is rectangle with sides 5 mi and 2 mi is

A=5\cdot 2=10\ mi^2.

As you can see the shape has all four lateral faces of the same rectangular form with the same sides lengths, therefore,

LA=4A=4\cdot 10=40\ mi^2.

Answer: correct choice is B.

What is the domain and derivative of f(x)=ln(2xsqrt(2+x))?
harkovskaia [24]
Domain is the numbers yo can use
we has a sqrt and a ln
we cant have any neagtive ln's or sqrts
x cannot be negative
it cannot be 0 either
domain is all numbers bigger than 0


deritivive
apply chain rule
dy/dx(f(g(x))=f'(g(x))g'(x)
and also
dy/dx (lnx)=1/x
and
dy/dx(f(x)g(x))=f'(x)g(x)+g'(x)f(x)
and from experience
dy/dx(sqrtx)=1/(2√x)


so

dy/dx(ln(2xsqrt(2+x)))=
(1/(2xsqrt(2+x))(2)(sqrt(2+x)+(x/(2sqrt(2+x))=
(3x+4)/(2x(x+2))



domain is all real numbers greater than 0
derivitive is \frac{3x+4}{2x(x+2)}
