Consider the quadratic function f(x)=−x^2−6x−4, which has been given a restricted domain, as shown in the following graph. What is the domain of f(x)? A) x≤−1
B) x≥−1
C)all multiples of 2
D)all real numbers

1. are the triangles similar and if so why? what is the value of x? show your work.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

The quadratic function h(t)=-16.1t^2+150 choose the graph representation
