Suppose a ladder of length 16 feet rests against a wall, and we pull the base of the ladder horizontally away from the wall. for a given distance x that we pull the ladder horizontally, let g(x) be the height of the ladder on the wall, under the assumption that the other end of the ladder always contacts the wall. we know from pythagorean theorem that for every x: x^2 + [g(x)]^2 = 16^2. (a) at what rate is the height changing when x=6? when the ladder is4feet from the ground (g(x) =4)? (b) write a formula for q'(x) in terms of x and g(x).

Jonathan pays $1.90 per pound for potatoes. he buys 8.3 pounds of potatoes. he determines that he will pay $15.77, before tax, for the potatoes. which best describes the reasonableness of jonathan’s solution? jonathan’s answer is reasonable because there are two decimal places in the factors and two in the product. jonathan’s answer is unreasonable because there are three decimal places in the factors and two in the product. jonathan’s answer is reasonable because is 16, and 16 is close to 15.77. jonathan’s answer is unreasonable because is 8, and 8 is not very close to 15.77.
