Giselle washes her favorite jeans once a week. They come out five millimeters shorter each time she washes them. Define units for the time Giselle has been washing her jeans and the number of millimeters Giselle's jeans have shrunk. 1. How many millimeters shorter will Giselle's jeans be after twelve weeks? 2. How much shorter will her jeans be after one year? (Hint: there are 52 weeks in a year.) 3. Her favorite jeans are becoming high-water pants! They've shrunk 40 millimeters already. For how many weeks has she washed them?

Factor the trinomial. Check the factorization using FOIL multiplication. \( y^{2}-20 y+75 \) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. 1 A. \( y^{2}-20 y+75= \) B. The trinomial is prime.

Use the discriminant to determine all values of k which would result in the graph of the equation \( y=k x^{2}-18 x+27 \) being tangent to the \( x \)-axis.

For a nonzero constant a, find the intercepts of the graph of \( \left(x^{2}+y^{2}\right)^{2}=a^{2}\left(x^{2}-y^{2}\right) \). Then test for symmetry with respect to the \( x \)-axis, the \( y \)-axis, and the origin. What are the intercepts? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The intercept(s) is/are (Use a comma to separate answers as needed. Type an ordered pair.) B. There are no intercepts. Test ( \( \left.x^{2}+y^{2}\right)^{2}=a^{2}\left(x^{2}-y^{2}\right) \) for symmetry with respect to the \( x \)-axis, the \( y \)-axis, and the origin. Select all that apply. A. The graph of the equation is symmetric with respect to the \( x \)-axis. B. The graph of the equaxtion is symmetric with respect to the \( y \)-axis. C. The graph of the equation is symmetric with respect to the origin. \( \square \) D. The graph of the equation is not symmetric.

Find the derivative of the given function. \( y=x^{11 / 5} \) \( y^{\prime}=\square \)
