Question 1(multiple choice worth 2 points)bob is driving along a straight and level road toward a mountain. at some point on his trip, he measures the angle of elevation to the top of the mountain and finds it to be 21°44'. find the height of the mountain to the nearest foot if bob is 13,428.7 feet from the center of the mountain at the base. 5453 ft 5353 ft 53,534 ft 535,342 ft

The answer to you question is 5353 because height=13428.7 x tan (21’44’) = 5353

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.
