EXPLANATION

The given expression is:

4^2×2^3- (14-16)÷2

Deal with the parenthesis first.

4^2×2^3- ( - 2)÷2

4^2×2^3 + 2÷2

Deal with exponents,

16×8+ 2÷2

Divide now

16×8 + 1

Multiply

128 + 1

You can now add to get

Answer: Ratio of black horses to all horses = 59/62

Step-by-step explanation:

Total number of horses = 62

Total number of white horses = 3

Assuming that the rest horses are black. That means the total number of black horses would be 62-3 =59. So there are 59 black horses and there are 3 white horses.

Ratio of black horses to all horses will be the total number of black horses / the total number of horses.

Ratio of black horses to all horses

= 59/62 or 59:62

It can also be expressed in decimals which will become

0.952

Evaluate the surface integral. S x2z2 dS S is the part of the cone z2 = x2 + y2 that lies between the planes z = 4 and z = 5
sammy [17]
The surface S can be parameterized in cylindrical coordinates using

\mathbf r(u,v)=(x(u,v),y(u,v),z(u,v))=(u\cos v,u\sin v,u)

where 4\le u\le5 and 0\le v\le2\pi. The surface integral is then equivalent to

\displaystyle\iint_Sx^2z^2\,\mathrm dS=\int_{v=0}^{v=2\pi}\int_{u=4}^{u=5}(u\cos v)^2u^2\left\|\mathbf r_u\times\mathbf r_v\right\|\,\mathrm du\,\mathrm dv
=\displaystyle\sqrt2\int_{v=0}^{v=2\pi}\int_{u=4}^{u=5}u^5\cos^2v\,\mathrm du\,\mathrm dv
=\dfrac{3843\pi}{\sqrt2}
