Evaluate the surface integral. S xz ds, s is the part of the plane 2x 2y z = 4 that lies in the first octant
maksim [4K]

The value of the given surface integral is 4.

The given plane intercepts the coordinate axes at (2, 0, 0), (0, 2, 0), and (4, 0, 0). These point are the coordinates of a triangular region that we can parameterize using.

S(u,v)=(1-u)((1-u)(2,0,0)+u(0,2,0)+u(4,0,0)\\S(u,v)=(2(1-u)(1-v),2u(1-v),4v)

<h3>What is the surface integral?</h3>

A surface integral is a generalization of multiple integrals to integration over surfaces. It can be thought of as the double integral analog of the line integral. Given a surface, one may integrate a scalar field over the surface or a vector field.

with 0≤u≤1 and  0≤v≤1. Then the surface element ds  is equivalent to

ds=\||\:\left(s_u\times \:\:S_v\right)||dudv=12\left(1-v\right)dudv

The surface integral is then

\int \:\int \:_Sxzds=12\int _0^1\:\int _0^1\:\left(2\left(1-u\right)\left(1-v\right),2u\left(1-v\right),4v\right)dvdu=4

Therefore the value of the given surface integral is 4.

Hobbs Mules charges $80 for a 2-hour mule ride and $144 for a 4-hour mule ride. The table down below shows how much McGee Mules
Nataliya [291]

Answer: If a group wants to take a 3 hour ride they should choose Hobbs Mules.

Step-by-step explanation:

First figure out how much a 3 hour ride at McGee Mules would cost. Do this by setting up a proportion, then solving it.

Numerator = Time       Denominator = Cost

\frac{1}{42} = \frac{3}{x}  42 x 3 = 126/1 = 126  So a 3 hour ride with Mcgee should cost $126.

Next figure out how much a 3 hour ride at Hobbs Mules would cost by doing the same thing.

\frac{2}{80} = \frac{3}{x}   80 x 3 = 240/2 = 120  So a 3 hour ride with Hobbs should cost $120.

In conclusion, The group should choose Hobbs because they price is $6 cheaper.

I am between 40 and 80. When my digits are reversed i am another prime number
Maurinko [17]

Answer:

42 times

Step-by-step explanation:

Since there are 6 sides on a fair dice, each having a number 1 thru 6 with no numbers repeating and half those numbers being odd, Bridget can expect to roll an odd number 84*(1/2) times. So our answer is 42.

Also, if you could please mark this "brainliest" (the crown) it would help a lot!

The two parallel sides of a trapezium are 19.8 and 7.2 and its area is 135 cm²..find its height
Virty [35]

Answer:

10cm

Step-by-step explanation:

the formula for an area of a trapezium:

\frac{(a + b) \times h}{2}  = area

where a and b are the parallel sides and h is the height. equating what we have:

\frac{(19.8 + 7.2) \times h}{2}  = 135

simplify the numerator by adding 19.8 and 7.2=27

\frac{27h}{2}  = 135

multiply both sides by 2

27h = 270

divide both sides by 27

h =  \frac{270}{27}  = 10

the height is 10cm
