In my 7th hour i made friends with this girl named Alexis and I mean she was very good friend at first and I just took it as she was a vey touchy person at first and i mean we've been friends for a few months now but I've taken some time to think about how she acts and even talked to some friends abut he due to recently I talked to her about my mental health and she pulled a coin purse out of her bag and gave me a razor blade out of it and said "its ok bestie we can kill..ourselves together" and no I didn't use it one of my other friends came to me and took it and threw it away but she's done other things that are weird on multiple occasions there was a crop top i would wear i got dress coded for wearing it but that didn't stop me from wearing it anyways i just threw an oversized flannels over it so the school wouldn't say anything about it but i showed my chest a she would play with my hair and she would touch my chest and made comments on my chest when I wore it to the point then ever i wore that shirt to school when i got to that class I would cover up and button my flannel and when i wear a skirt sometimes she'll lift my skirt to look under it or touch under my skirt and she'll try to kiss me like the most she has done is give me a kiss on the cheek and she even knows I have a girl. friend of 14 months she's known since the beginning of our friendship but she doesn't care that wont ever stop her She'll even go as far as the tell me when me and my girl. friend break up that I better date her and ill say but ill need time to recover for a very long time and she says no you don't you have me i feel l like a really bad person for letting this happen i feel like i need to get help I already know something worse is going to happen i can just feel it i don't know who to go how do I tell my girl. friend what do I do please help

Airplane speeds are measured in three different ways: (1) indicated speed, (2) true speed, and (3) ground speed. the indicated airspeed is the airspeed given by an instrument called an airspeed indicator. a plane’s indicated airspeed is different from its true airspeed because the indicator is affected by temperature changes and different altitudes of air pressure. the true airspeed is the speed of the airplane relative to the wind. ground speed is the speed of the airplane relative to the ground. for example, a plane flying at a true airspeed of 150 knots into a headwind of 25 knots will have a ground speed of 125 knots. the problems below refer to static and dynamic pressure. static pressure is used when a body is in motion or at rest at a constant speed and direction. dynamic pressure is used when a body in motion changes speed or direction or both. a gauge compares these pressures, giving pilots an indicated airspeed. in problem #s 1 and 2, use the following information. the indicated airspeed s (in knots) of an airplane is given by an airspeed indicator that measures the difference p (in inches of mercury) between the static and dynamic pressures. the relationship between s and p can be modeled by s=136.4p√+4.5. 1. find the differential pressure when the indicated airspeed is 157 knots. 2. find the change in the differential pressure of an airplane that was traveling at 218 knots and slowed down to195 knots. in problem #s 3 and 4, use the following information. the true airspeed t (in knots) of an airplane can be modeled by t=(1+a50,000) ⋅ s, where a is the altitude (in feet) and s is the indicated airspeed (in knots). 3. write the equation for true airspeed t in terms of altitude and differential pressure p. 4. a plane is flying with a true airspeed of 280 knots at an altitude of 20,000 feet. estimate the differential pressure. explain why you think your estimate is correct.
