Agraphing calculator is recommended. use the squeeze theorem to show that lim x → 0 (x2 cos(15πx)) = 0. illustrate by graphing the functions f(x) = −x2, g(x) = x2 cos(15πx), and h(x) = x2 on the same screen. let f(x) = −x2, g(x) = x2 cos(15πx), and h(x) = x2. then ≤ cos(15πx) ≤ ⇒ ≤ x2 cos(15πx) ≤ . since lim x→0 f(x) = lim x→0 h(x) = , by the squeeze theorem we have lim x→0 g(x) = .

The fence around a quadrilateral-shaped pasture is 3a^2+15a+9 long. three sides of the fence have the following lengths: 5a, 10a-2, a^2-7. what is the length of the fourth side of the fence?

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
