My guess is that when you get a world problem including fractions, the word "of" is going to be talking about the whole of the problem and the word "is" only talks about a part of it. For example, the fraction is 2 of 3. 3 is the whole since it correlates the the word "of". 2 is the part of the whole, because it uses "is." 2/3

Evaluate the triple integral_E x^6e^y dV where E is bounded by the parabolic cylinder z = 25 - y^2 and the planes z = 0, x = 5,
Nimfa-mama [501]

Nothing crazy here, just a matter of figuring out the limits of integration.

\displaystyle\iiint_Ex^6e^y\,\mathrm dV=\int_{-5}^5\int_{-5}^5\int_0^{25-y^2}x^6e^y\,\mathrm dz\,\mathrm dy\,\mathrm dx

=\displaystyle\int_{-5}^{-5}\int_{-5}^5x^6e^y(25-y^2)\,\mathrm dy\,\mathrm dx

=\displaystyle\left(\int_{-5}^5x^6\,\mathrm dx\right)\left(\int_{-5}^5e^y(25-y^2)\,\mathrm dy\right)=\boxed{\frac{625,000(3+2e^{10})}{7e^5}}

Given the arc length of a circle is 127π centimeters and the subtended angle is 60˚. Find the Circumference of the circle.
Mumz [18]

The circumference of the circle is 762π cm.

<h3>What is length of arc of a circle?</h3>

The length of arc a circle can is determined with the radius and central angle of the arc.

The radius of the circle is calculated as follows;

L = \pi r \times \frac{ \theta }{180} \\\\&#10;\pi r \theta = 180 L\\\\&#10;\pi  r = \frac{180 L}{\theta}

The circumference of the circle is calculated as follows;

C = 2\pi r\\\\&#10;C = 2(\pi  r)\\\\&#10;C = 2(\frac{180 \ L}{\theta } )\\\\&#10;C = 2(\frac{180 \times 127\pi}{60 } )\\\\&#10;C = 762 \pi \ cm

An air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute. Select all
Radda [10]

Answer:

The correct options are 3, 4 and 5.

Step-by-step explanation:

It is given that an air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute.

It means the initial height of air balloon is 1000. So, the y-intercept is (0,1000).

The ball falls at a rate of 50 ft per minute. So, the rate of change is

m=-50

The height of balloon is defined as

h(x)=-50x+1000                      [\because y=mx+b]

Where, x is time in minutes.

The balloon will reach the ground when h(x)=0

0=-50x+1000

50x=1000

x=20

Therefore the options 3, 4 and 5 are correct.
