Write g(x) = 40x + 4x2 in vertex form. write the function in standard form. factor a out of the first two terms. form a perfect square trinomial. write the trinomial as a binomial squared. g(x) = 4x2 + 40x g(x) = 4(x2 + 10x) (10/2)^2= 25 g(x) = 4(x2 + 10x + 25) – 4(25) g(x) = (x + – fill the blanks.

Suppose a man is heterozygous for heterochromia, an autosomal dominant disorder which causes two different‑colored eyes in an individual, produced 25‑offspring with his normal‑eyed wife. of their children, 15 were heterochromatic and 10 were‑normal. calculate the chi‑square value for this observation.

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.
