(1 point) Find a vector function that represents the curve of intersection of the paraboloid $$z=7x^2+2y^2$$ and the cylinder $$y=2x^2$$. Use the variable t for the parameter. $$\mathbf{r}(t)=?t,$$ Use $$\cos (t)$$ and $$\sin (t)$$, with positive coefficients, to parametrize the intersection of the surfaces $$x^2+y^2=25$$ and $$z=8x^3$$. $$\mathbf{r}(t)=?$$ (1 point) Find a parameterization for the curve shown in the figure below.
