=3.4= 66. I couldn't get just one line would show up. I don't know what that means. 68. x= .572 70. x=3.847 72. x=16.636 100. x=3.426 done by Matt Bogaert

I agree with all but 66 I got .247 and for 100 I got -2.27 and 7.127 checked by Justin Ivins __#102.__ lnx+ln(x^2+4)=10 ln(x^3+4x)=10 y1=ln(x^3+4x) y2=10 x=27.984

__#104__. y1= 4 y2=3^(x+1)-2 (.631,4)

__#106.__ y1=500 y2=1500e^(-x/2) (2.194,500)

__#119.__ true The x intercept of y=(2/3)e^x - 42 is 4.1431347 so when you plug that number into the equation (2/3)e^x = 42 it works out to be equal

__#120.__ True, otherwise the equation would have no solution

Okay so I got that R^2 = .98725 for ExpReg and that R^2 = .98396 for PwrReg! My graphs were different for two of them aswell but I think my calculator is messed up or I might be doing something wrong because they all look almost identica! But I got the same answer for C and D! Checked By: Courtney Venable

Looks good! I got the same answers! 30 Checked by Morgan Miller

for 3.6: 37. True because the exponential growth model is y=ae^bx if b>0 38. True. For example y=3(2^X) can be rewritten as y= 3(2^X) = 3e^(ln2)x = 3e^.693x done by Rachel West
