The EXPONENTIAL REGRESSION equation obtained by fitting the data is $y = 58.031(0.964)^x$

To obtain the exponential regression equation which models the data, we could use technology, we involves Inputting the data into an EXPONENTIAL REGRESSION CALCULATOR or EXCEL

Using an exponential regression calculator :

The regression equation obtained is :

$y = 58.031(0.964)^x$

The general function of an exponential regression function is : $AB^x$

A = 58.031 = Initial value ; B = Decay factor

Hence, the EXPONENTIAL REGRESSION EQUATION obtained using technology is : $y = 58.031(0.964)^x$

U is the midpoint of line segment XY. if XU=6x-7 and UY=4x+9, find the value of x and the measure of XY.

n200080 [17]

Answer:

Since U is the midpoint of XY, $XU = UY\\or, 6x-7 = 4x+9\\or, 6x - 4x = 7+9\\or, 2x = 16\\or, x = 8\\XY = XU +UY = 6x - 7 + 4x +9 = 10x+2 = 10(8) +2 = 82$
