In the given triangle ABC, angle A is 90° and segment AD is perpendicular to segment BC. PLEASE HELP I CANT FIGURE THIS OUT AT ALL 50 POINTS AND MARKING U SMARTEST THING! The figure shows triangle ABC with right angle at A and segment AD. Point D is on side BC. Part A: Identify a pair of similar triangles. Part B: Explain how you know the triangles from Part A are similar. Part C: If DB = 9 and DC = 4, find the length of segment DA. Show your work.

Y=4x^2+x-1 solve using quadratic formula

What is the length of the missing leg in this right triangle? 18 mm 24 mm 26 mm 32 mm

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
