Given the directrix of y = 4 and focus of (0, 2), which is the equation of the parabola?

Find the zeros of the function. write the smaller solution first, and the larger solution second f(x)= (x+6)^2-49

An assembly consists of two mechanical components. suppose that the probabilities that the first and second components meet specifications are 0.87 and 0.84. assume that the components are independent. determine the probability mass function of the number of components in the assembly that meet specifications. x

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