im in the eighth grade i need help with finding equation using scatter plots

I would love to get a written solution. I did the other proof tree that you can see in the attaached files. So its supposed to look like that Thank You.

d. I need help on part A especially.

b the link is https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion_en.html and these are the questions 2: Raise the cannon to a height of 15 meters. Set the horizontal velocity to 12 m/sa) Sketch the situationb) Predict the distance you have to place the target from the base of the cannon (calculate this & show all work). c)Perform the experiment by placing the target at the predicted range and clicking the cannon button. Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the target?) 3: Raise the cannon to a height of 5 meters. Measure the distance of the David statue from the base of the cannona) Sketch the situation.b) Predict the velocity with which you have to launch the object in order for it to hit the statue (calculate this & show all work).c)Perform the experiment by entering the predicted velocity and clicking Fire. Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the statue?) If they disagree, look at your math again! 4: Set the initial velocity of the object to 20 m/s. Place the target at a range (distance) 20 m.a) Sketch the situation.d) Predict the height from which you have to launch the object in order for it to land on the target (calculate this & show all work).b) Perform the experiment by raising the cannon to the predicted height and clicking Fire! Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the target?) If they disagree, look at your math again!

rectangular sheet of paper, AB 15cm and BC 12= so that the fold line goes through the corner A and the corner B ends up in the figure. Calculate the area of ​​the quadrilateral AECD and the triangle ABC. 12cm. The sheet is folded to the side of the CD, see

e are three questions but im putting one here. Shen invested his savings in two investment funds. The 8000 that he invested in Fund A returned a 5% profit. The amount that he invested in Fund B returned a 2% profit. How much did he invest in Fund B, if both funds together returned a 4% profit?

way where the teacher makes a math problem and im like
