[Jawaban] Graph the polynomial function [tex]f(x)=-2(x-3)^2\left(x^2-25\right)[/tex] using parts (a) through (e). (a) Determine the end behavior of the graph of the function. The graph of [tex]f[/tex] behaves like [tex]y=-2 x^4[/tex] for large values of [tex]|x|[/tex]. (b) Find the [tex]x[/tex]- and [tex]y[/tex]-intercepts of the graph of the function. The [tex]x[/tex]-intercept(s) is/are

[Jawaban] The final velocity of an object moving in one dimension is given by the formula [tex]$v=u+a t$[/tex], where [tex]$u$[/tex] is the initial velocity, [tex]$a$[/tex] is the acceleration, and [tex]$t$[/tex] is the time. Solve this equation for [tex]$t$[/tex]. To solve for [tex]$t$[/tex], first subtract [tex]$u$[/tex] from both sides of the equation. Subtracting [tex]$u$[/tex] from both sides of the equation results in: [tex]$v-u=a t$[/tex] Solve this equation for [tex]$t$[/tex]. A. [tex]$t=(v-u)-a$[/tex] B. [tex]$t=(v-u)+a$[/tex] C. [tex]$t=a(v-u)$[/tex] D. [tex]$t=(v-u) / a$[/tex]

[Jawaban] Suppose that you decide to buy a car for $25,635, including taxes and license fees. You saved $6000 for a down payment and can get a five-year car loan at 6.43%. Use PMT = [tex]$\frac{P\left(\frac{r}{n}\right)}{\left[1-\left(1+\frac{r}{n}\right)^{-n t}\right]}$[/tex] to find the monthly payment and the total interest for the loan. The monthly payment is $ [ ]. (Round to the nearest cent as needed.)
