Answer:

h = 19.7 ft.

Step-by-step explanation:

Use the Pythagoras Theorem

$(Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\\\(20)^2=(3.5)^2+(h)^2\\400=12.25+h^2\\400-12.25=h^2\\387.75=h^2\\$

Now we take square root on both sides,

$\sqrt{387.75} =\sqrt{h^2}\\19.69=h\\h=19.7\ ft\\$

so the value of h equals 19.7 ft.

Help me about this integral

NemiM [27]

The gradient theorem applies here, because we can find a scalar function f for which ∇ f (or the gradient of f ) is equal to the underlying vector field:

$\nabla f(x,y,z)=\langle2xy,x^2-z^2,-2yz\rangle$

We have

$\dfrac{\partial f}{\partial x}=2xy\implies f(x,y,z)=x^2y+g(y,z)$

$\dfrac{\partial f}{\partial y}=x^2-z^2=x^2+\dfrac{\partial g}{\partial y}\implies\dfrac{\partial g}{\partial y}=-z^2\implies g(y,z)=-yz^2+h(z)$

$\dfrac{\partial f}{\partial z}=-2yz=-2yz+\dfrac{\mathrm dh}{\mathrm dz}\implies\dfrac{\mathrm dh}{\mathrm dz}=0\implies h(z)=C$

where C is an arbitrary constant.

So we found

$f(x,y,z)=x^2y-yz^2+C$

and by the gradient theorem,

$\displaystyle\int_{(0,0,0)}^{(1,2,3)}\nabla f\cdot\langle\mathrm dx,\mathrm dy,\mathrm dz\rangle=f(1,2,3)-f(0,0,0)=\boxed{-16}$

A box contains 95 pink runner bands and 90 brown rubber bands. You select a rubber band at random from the box. Find each probab

vovikov84 [41]

Given:
95 pink rubber bands
90 brown rubber bands

185 rubber bands in all.

Probability of pink : 95/185 ⇒ 19/37

95 ÷ 5 = 19
185 ÷ 5 = 37

Probability of brown : 90/185 ⇒ 18/37

90 ÷ 5 = 18
185 ÷ 5 = 37
