A line passes through the points (4, 9) and (-9, -5).Find the slope of the line. Read the following excerpt from the Truman Doctrine and answer the question below."The seeds of totalitarian regimes are nurtured by misery and want. They spread and grow in the evil soil of poverty and strife. They reach their full growth when the hope of a people for a better life has died.We must keep that hope alive.The free people of the world look to us for support in maintaining their freedoms."Describe the tone of President Truman's address to Congress. Jasmine, multiply your age by 3 and add 6. Then multiply this sum by 2. James, multiply your age by 2 and add 4. Then multiply this sum by 3. I predict you will both get the same number! An initially uncharged sphere is on an insulated stand and isolated in a chamber. The charge on the sphere is monitored as a beam of monochromatic light shines on the sphere. Initially nothing happens. The wavelength of the light is slowly decreased. When the wavelength reaches a certain value, a positive charge is suddenly measured on the sphere. The wavelength is then held constant, and the charge continues to increase at a constant rate. The intensity of the beam is then increased without the wavelength being changed, and the rate of increase of the charge becomes greater.Required:a. In a coherent paragraph-length response, describe the cause of the charge on the sphere and the changes in the observations about the charge, in terms of physics principles.b. An electron in the chamber is moving with speed 210^5m/s when it collides with a positron (a particle identical to an electron except for the sign of its charge) moving with the same speed in the opposite direction. The particles annihilate each other. How much energy is released due to the annihilation?c. In another experiment, a beam of electrons with uniform wavelength e is incident on a slit, where the width of the slit is much larger than e. A detector is placed near the slit, but no diffraction pattern is observed. What change should be made that would result in a diffraction pattern? Indicate why this change is the one needed. How do you say together in french ?

Can someone pleaseeee help and if youre correct ill give brainliest Help me solve this !!! Math problem! Answer the statistical measures and create a box and whiskers plot for the following set of data.1, 1, 6, 10, 12, 13, 13, 14, 16, 19Min:Q1:Med:Q3:Max: A store boght 100 toys a a cost of $10 each.
