Find r(t) if r'(t) = 5t4i + 6t5j + t k and r(1) = i + j.

Vladimir [108]

$\mathbf r(t)=\displaystyle\int(5t^4\,\mathbf i+6t^5\,\mathbf j+t\,\mathbf k)\,\mathrm dt$
$\mathbf r(t)=(t^5+C_1)\,\mathbf i+(t^6+C_2)\,\mathbf j+\left(\dfrac12t^2+C_3\right)\,\mathbf k$

Given $\mathbf r(1)=\mathbf i+\mathbf j$ , we have

$\begin{cases}1^5+C_1=1\\\\1^6+C_2=1\\\\\dfrac121^2+C_3=0\end{cases}\implies C_1=0,C_2=0,C_3=-\dfrac12$

so that the particular solution is

$\mathbf r(t)=t^5\,\mathbf i+t^6\,\mathbf j+\dfrac12(t^2-1)\,\mathbf k$

Suraj took a slice of Pizza from the freezer and put it in the oven the pizza temperature in degrees Celsius as a function of ti

stepan [7]

Answer:

The oven heat the pizza at 8 degree Celsius per minute

Step-by-step explanation:

Select any two points on the graph.

(I take these as they lie on grid lines)

(0.75,0) and (2,10)

now calculate slope using these two points

slope = change in Y ÷ change in X

= (10-0) ÷ (2-0.75)

= 8

So, the oven heat the pizza at 8 degree Celsius per minute
