Find $r(t)$ if $r'(t) = 9t^2i + 9t^2j + \sqrt{t}k$ and $r(1) = i + j$ Step 1 Integrals of vector functions are obtained by integrating each component separately. Therefore, if $r'(t) = 9t^2i + 9t^2j + \sqrt{t}k$, then $r(t) = \int 9t^2 dt i + \int 9t^2 dt j + \int \sqrt{t} dt k = t^3 i + t^3 j + \frac{2}{3}t^{\frac{3}{2}} k + C$ Step 2 The next step is to find the constant vector $C$. We are given that $r(1) = i + j$, but the results of the integration also tell us that $r(1) = i + j + \frac{2}{3}k + C$. We now compare these two equations for $r(1)$ and solve for $C$. Solving $i + j = i + j + \frac{2}{3}k + C$ gives us $C = -\frac{2}{3}k$ Step 3 Combining this result for $C$ into the general form of $r(t)$, we get $r(t) = t^3 i + t^3 j + \frac{2}{3}t^{\frac{3}{2}} k - \frac{2}{3}k = t^3 i + t^3 j + (\frac{2}{3}t^{\frac{3}{2}} - \frac{2}{3})k$

The assertion is false. The empirical evidence of bunching of reported earnings at the EITC-maximizing earnings threshold suggests that individuals are adjusting their reported earnings to maximize their EITC benefits, rather than behaving according to the standard model of labor supply. This behavior indicates that the standard model may not accurately capture the complexities of actual labor supply behavior.
