Given:

What is the value of x?

andre [41]

Answer:

D.11.1

Step-by-step explanation:

first, let's use the SOHCAHTOA strategy. for people that don't know, it means:

Sine(angle)= side Opposite to the angle/Hypotenuse (SOH)

Cosine(angle)= side Adjacent to the angle/Hypotenuse (CAH)

Tangent(angle)= side Opposite to the angle/side Adjacent to the angle (TOA)

now, since the question describes both the hypotenuse and the side opposite to the angle, we will use Sine to find the length, according to the SOHCAHTOA strategy. This means that the equation will be:

Sin(46)=8/x

Now, we punch in the first half of our equation, Sin(46), into the calculator. it should pop up as:

Sin(46)=0.7193398

now, we substitute that in our original equation, and make it like this:

0.7193398=8/11.1

now, everything will be pretty easy. First, round the decimal into something easier, in this case, 18/25. Now, the equation will be:

18/25=8/x

from here, we can cross multiply to get the x. your fraction should be:

18x/200

so, x=200/18. convert it into a decimal, we get:

11.1111111...

now, we find the number closest to 11.11, which is 11.1, making the answer 11.1, or D.

Let f be a scalar field and F be a vector field. The following expressions either represent scalar fields, vector fields, or are

Mama L [17]

Answer:

(a) curl f - meaningless

(b) grad f -Δf- vector field

(c) div F - scalar field

(d) curl( grad f )curl (Δf)- vector field (e) grad F -ΔF- meaningless

(f) grad( div F )-Δ(divF) - vector field

(g) div( grad f ) - div(Δf)- scalar field

(h) grad ( div f ) -Δ(div f)-meaningless

(i) curl ( curl F ) - vector field

(j) div( div F ) - meaningless

(k) ( grad f ) x ( div F ) -(Δf) x (divF)-meaningless

(l) div( curl( grad f )) -div(curl(Δf))-scalar field

Step-by-step explanation:

(a) curl f - meaningless; a curl can only be taken of a vector field

(b) grad f - vector field; a gradient results in a vector field

(c) div F - scalar field; a divergence results in a scalar field

(d) curl( grad f ) - vector field; the curl of a vector field results in a vector field

(e) grad F - meaningless; a gradient can only be taken of a scalar field

(f) grad( div F ) -vector field ; the gradient of a scalar field is a vector field

(g) div( grad f ) - scalar field; the divergence of a vector field is a scalar field

(h) grad ( div f ) - meaningless; the divergence of a scalar field can not be taken

(i) curl ( curl F ) - vector field; the curl of a vector field is a vector field

(j) div( div F ) - meaningless; the divergence of a scalar field can not be taken

(k) ( grad f ) x ( div F ) - meaningless; a vector and scalar field cannon be crossed

(l) div( curl( grad f )) - scalar field; the divergence of a vector field is a scalar field
