If f is a scalar field and f, g are vector fields, then f f, f · g, and f × g are defined by the following.(f f)(x, y, z) = f(x, y, z) f(x, y, z)(f · g)(x, y, z) = f(x, y, z) · g(x, y, z)(f × g)(x, y, z) = f(x, y, z) × g(x, y, z) find an identical expression, assuming that the appropriate partial derivatives exist and are continuous.

a. curl(f f)f div f + f · ∇f
b. grad(div f) − ∇2f f
c. curl f + (∇f) × ff d
d. f + (∇f) × f
e. none of above

the answer is d on edge

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

d. you cannot tell because there are no values shown.
