WILL MARK BRAINLIEST IF HELP WITH CONICS HYPERBOLAS PROBLEM!

Write the equation of a hyperbola, centered at the origin, given the following values.
Foci (±9,0), vertices (±4,0)

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

Does anyone know how to do geometryme with this problem

Which of the following is the explicit rule for a geometric sequence defined a recursive formula of a -5a for which the first term is 23?
