Complete parts​ (a) through​ (c) using the following data.

Row 1 2 2 2 5 5 5 5 6 7 7
Row 2 92 82 83 79 90 73 79 82 59 70 ​

Construct a scatter plot of the data and draw the regression line. Plot Row 1 on the horizontal axis and Row 2 on the vertical axis.

(a) Find the equation of the regression line for the given​ data, letting Row 1 represent the​ x-values and Row 2 the​ y-values. Sketch a scatter plot of the data and draw the regression line. Input the values of the slope and intercept for the regression line when Row 1 represents the​ x-values.

​(Round to three decimal places as​ needed.)

​(b) Find the equation of the regression line for the given​ data, letting Row 2 represent the​ x-values and Row 1 the​ y-values.

Sketch a scatter plot of the data and draw the regression line. Input the values of the slope and intercept for the regression line when Row 2 represents the​ x-values.

y = x( ) +( )

1). Find the dervatives dy/dx and d^2/dx^2 , and evaluate them at t = 2.

x = t^2 , y= t ln t

2) Find the arc length of the curve on the given interval.

x = ln t , y = t + 1 , 1 < or equal to t < or equal to 2

3) Find the area of region bounded by the polar curve on the given interval.

r = tan theta , pi/6 < or equal to theta < or equal to pi/3

4) Find the length of the polar curve on the given interval

r = (theta)^2 , 0 < or equal to theta < or equal to pi/2

analysis of algorithm

Using kinematic relation s = v_0t +(1/2)at^2 , I got the 2 equations: 172.8m = 5.682V_0 + 16.143a and 140.3m = 4.930V_0 + 12.152a. How do I get Initial velocity and acceleration out of that? m=meters and t is seconds
