1) A projectile is thrown upward so that its distance above the ground after t seconds is

leonid [27]

Answer:

After 22 seconds the projectile reach its maximum height of 4,840 units

Step-by-step explanation:

we have

$h(t)=-10t^{2}+440t$

This is a vertical parabola downward (because the leading coefficient is negative)

The vertex is a maximum

Find out the coordinates of the vertex

Convert the quadratic equation in vertex form

Factor -10

$h(t)=-10(t^{2}-44t)$

Complete the square

$h(t)=-10(t^{2}-44t+22^2)+(10)(22^2)$

$h(t)=-10(t^{2}-44t+22^2)+4,840$

Rewrite as perfect squares

$h(t)=-10(t-22)^{2}+4,840$

The vertex is the point (22,4,840)

therefore

After 22 seconds the projectile reach its maximum height of 4,840 units

Let f = ay i + bz j + cx k where a, b, and c are positive constants. let c be the triangle obtained by tracing out the path from

oee [108]

You can either compute three line integrals, or use Stokes' theorem and compute one surface integral. I prefer the latter.

The curl of the given vector field is

$\nabla\times\mathbf f(x,y,z)=-b\,\mathbf i-c\,\mathbf j-a\,\mathbf k$

Parameterize the triangular surface bounded by $\mathcal C$ - I'll call it $\mathcal S$ - by

$\mathbf s(u,v)=7\,\mathbf i+6v\,\mathbf j+2(u+v-uv)\,\mathbf k$

with $0\le u\le1$ and $0\le v\le1$ . By Stokes' theorem, we have

$\displaystyle\int_{\mathcal C}\mathbf f(x,y,z)\cdot\mathrm d\mathbf r=\iint_{\mathcal S}\nabla\times\mathbf f(x,y,z)\cdot\mathrm d\mathbf S$

where $\mathcal S$ is positively oriented; that is, every vector normal to $\mathcal S$ is pointed in the positive $x$ direction. The surface element is given by

$\mathrm d\mathbf S=\mathbf s_u\times\mathbf s_v\,\mathrm du\,\mathrm dv$

So our integral is

$\displaystyle\int_{v=0}^{v=1}\int_{u=0}^{u=1}(-b\,\mathbf i-c\,\mathbf j-a\,\mathbf k)\cdot((12v-12)\,\mathbf i)\,\mathrm du\,\mathrm dv$
$\displaystyle=12b\int_{v=0}^{v=1}(1-v)\,\mathrm dv=6b$

The sum of 13 and Rhonda's height is 74.<br> Use the variable r to represent Rhonda's height.

VashaNatasha [74]

The equation is 13+r = 74. This is because the term "sum" means we add two or more values.

That equation solves to r = 61 after subtracting 13 from both sides.

Assuming the r value is her height in inches, it means Rhonda is 61 inches tall (i.e. 5 feet, 1 inch)
