Mathematics

Answer:

True

Step-by-step explanation:

Distance can never be negative as distance can't 'decrease' as it is a scalar quantity. Scalar only has magnitude.

DISPLACMENT is a vector quantity, which can be positive, 0, or even negative as it has magnitude and direction.

Hope that helps!

I need help on this?!

Sergio039 [100]

If you nee solving it will be:
c^6(-3c^5)^2
c^6(3c^5)^2
c^6·3^2(c^5)^2
c^6·9(c^5)^2
c^6·9c^10
9c^6c^10
9c^6+10
9c^16
So the answer is:
9c^16
(9c to the power of 16)
Sorry I was late..

Evaluate the surface integral. s xy ds s is the triangular region with vertices (1, 0, 0), (0, 8, 0), (0, 0, 8)

zmey [24]

Parameterize $S$ by

$\vec s(u,v)=(1-u)v\,\vec\imath+8uv\,\vec\jmath+8(1-v)\,\vec k$

with $0\le u\le1$ and $0\le v\le1$ .

Then the surface element is

$\mathrm dS=\|\vec s_u\times\vec s_v\|\,\mathrm du\,\mathrm dv=8\sqrt{66}\,v\,\mathrm du\,\mathrm dv$

and the surface integral is

$\displaystyle\iint_Sxy\,\mathrm dS=8\sqrt{66}\int_0^1\int_0^18(1-u)uv^3\,\mathrm du\,\mathrm dv=\boxed{8\sqrt{\dfrac{22}3}}$

A runner warms up for ten minutes and then takes seven minutes to run each mile The total time after r miles is 45 minutes . How

Charra [1.4K]

5 miles are ran total. Take away ten minutes of warm up from the total time of 45 minutes. You now have 35 minutes of running. You will now divide 35 minutes by 7 minutes. Which equals 5
