find the value of "m". the function is hyperbolic cosine

D. 9256= cosh ( 0. 4 m ) (osh (osm ) find value of "Q: 0. 9256 = cash (0.4m) cash (0.5 m ) A : STEP1 : we can rewrite the equation as: cosh (0.5 m ) = cosh ( 0.4.m ) 0. 9254 STEP 2 : Take the natural logarithm of both sides, and applying the properties of logarithms - In ( x ) , In ( y ) = incy In Ccosh (0.5m) ) = In ( cosh (0.4m) 0. 9254 =/ In (cosh (0.5m)) = In ( cosh (0.4m) ) - In (0.92ste) STEP 3 : Use the identity that In ( cosh ( x) ) = x, we get 0.5 m = 0- 4m - in (0- 9256) STEP : Solve for mi 0-5 m- 0. 4m = - In (0.9254) 0. Im = - in (0.9254, 0 -1 m = 0. 077613 10 0 . 1: 0 - 1 DMZ 0 77313103
