105. Half-life. Tritium is used in nuclear weapons to increase their power. It decays at the rate of \( 5.5 \% \) per year. Calculate the half-life of tritium.

Simplify. \( \sqrt{\frac{x^{12}}{x^{6}}}= \)

How many times larger is the required centripetal acceleration for a car rounding a curve at 65 MPH than for one rounding the same curve at 20 MPH ? (Round the final answer to four decimal places.) The centripetal acceleration is

4. Adaptador de corriente para computadora Problema: Un adaptador de corriente tiene una resistencia interno de \( 8 \Omega \) y debe operar con una corriente de 3 A. ¿Cuál es el voltaje de sallida del adaptador?

Part 8 What is another way to find the difference in the cost of 7 desktop computers and 7 laptop computers? Explain.

Consider the integral \( \int_{0}^{9} \int_{0}^{8 \sqrt{x}} f(x, y) d y d x \). Sketch the region of integration and change the order of integration. \( \int_{a}^{b} \int_{g_{1}(y)}^{g_{2}(y)} f(x, y) d x d y \) \( a=0 \) \( g_{1}(y)= \)
