Emma was studying the weights of ground hogs as they grow from babies to adulthood. She began her study when the baby was 5 oz and used the equation
w(t) = 5(1.2)' where t is a time in months to model this situation. She concluded
her study when the ground hog was about 80 oz.
Chose the best domain to represent this problem
A)*(0,15]
B) (5,80]
C) (0,18]
D) All reals greater than 0

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
