Answer:

it might be because they want you to try to figure out questions on your own. some people dont have the luxury to have someone help with math, so to make it fair i think they dont encourage it.

Let c be the curve of intersection of the parabolic cylinder x2 = 2y, and the surface 3z = xy. find the exact length of c from t

Mandarinka [93]

Parameterize the intersection by setting $x(t)=t$ , so that

$x^2=2y\iff y=\dfrac{x^2}2\implies y(t)=\dfrac{t^2}2$
$3z=xy\iff z=\dfrac{xy}3\implies z(t)=\dfrac{t^3}6$

The length of the path $C$ is then given by the line integral along $C$ ,

$\displaystyle\int_C\mathrm dS$

where $\mathrm dS=\sqrt{\left(\dfrac{\mathrm dx}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dy}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dz}{\mathrm dt}\right)^2}\,\mathrm dt$ . We have

$\dfrac{\mathrm dx}{\mathrm dt}=1$
$\dfrac{\mathrm dy}{\mathrm dt}=t$
$\dfrac{\mathrm dz}{\mathrm dt}=\dfrac{t^2}2$

and so the line integral is

$\displaystyle\int_{t=0}^{t=2}\sqrt{1^2+t^2+\dfrac{t^4}4}\,\mathrm dt$

This result is fortuitous, since we can write

$1+t^2+\dfrac{t^4}4=\dfrac14(t^4+4t^2+4)=\dfrac{(t^2+2)^2}4=\left(\dfrac{t^2+2}2\right)^2$

and so the integral reduces to

$\displaystyle\int_{t=0}^{t=2}\frac{t^2+2}2\,\mathrm dt=\dfrac{10}3$

Reuben dogs 2.25 miles every weekdayOn weekends he’s jogs 1.8 times as far to the nearest hundred how many miles does reuben

77julia77 [94]

Answer:

Distance covered by Reuben jogging in 4 calendar weeks = 61.2 miles

Step-by-step explanation:

Distance covered by Reuben jogging every weekday = 2.25 miles

Distance covered by Reuben jogging every weekends is 1.8 times as far as he covers in weekdays to nearest hundred.

To find Reuben jogs in 4 calendar weeks.

Solution:

Distance covered by Reuben jogging every weekends = $1.8\times 2.25\ miles= 4.05\ miles$
