- Using Figure 7, solve f(x)=1 .arrow_forwardFor the following exercises, use this scenario: A pot of boiling soup with an internal temperature of 100° Fahrenheit was taken off the stove to cool in a 69° F room. After fifteen minutes, the internal temperature of the soup was 95° F. Use Newton’s Law of Cooling to write a formula that models this situation.arrow_forwardFor the following exercises, use this scenario: A soup with an internal temperature of 350 Fahrenheit was taken off the stove to cool in at 71F room. After ?fteen minutes, the internal temperature of the soup was 175F. Use Newton’s Law of Cooling to write a formula that models this situation.arrow_forward
- For the following exercises, use Kepler’s Law, which states that the square of the time, T, required for a planet to orbitthe Sun varies directly with the cube of the mean distance. a. that the planet is from the Sun. 46. Using the Earth’s time of 1 year and mean distance of93 million miles, find the equation relating T and a.arrow_forwardFor the following exercises, use Kepler’s Law, which states that the square of the time, T, required for a planet to orbitthe Sun varies directly with the cube of the mean distance,a, that the planet is from the Sun. 48. Using Earth’s distance of 150 million kilometers, findthe equation relating T and a.arrow_forwardFor the following exercises, solve the application problem. 48.The volume V of an ideal gas varies directly with thetemperature T and inversely with the pressure P.A cylinder contains oxygen at a temperature of310 degrees K and a pressure of 18 atmospheres in avolume of 120 liters. Find the pressure if the volumeis decreased to 100 liters and the temperature isincreased to 320 degrees K.arrow_forward
- Repeat the previous exercise to find the formula forthe APY of an account that compounds daily. Usethe results from this and the previous exercise todevelop a function I(n)for the APY of any accountthat compounds n times per year.arrow_forwardFor the following exercises, use Figure 2 to approximate the values. 17. If f(x)=1 , then solve for x.arrow_forwardAn object is dropped from a tower, 1296 ft above the ground. The object's height above ground t seconds after the fall is s(t) = 1296 – 16t. Determine the velocity and acceleration of the object the moment it reaches the ground. The velocity of the object the moment it reaches the ground is ft/s. (Simplify your answer.)arrow_forward
- When an oven is turned off its interior temperature is given by T=70+330(0.8)7, where T is the temperature in (F) in the oven and t is the time in minutes after the oven is turned off. For each of the following, assume room temperature remains constant. What is the oven temperature (in F) after ten minutes?arrow_forwardA truck slows, doesn't quite stop at a stop sign, and then speeds up again in such a way that its speed at time t seconds is v(t) = 11 + |-5t + 40| ft/sec. How far does the truck travel from time t = 0 to time t = 10? 72 X ft Need Help? Read Itarrow_forwardConsider the following. (Give your answers correct to one decimal place.) (a) Find the value x(7, 0.05). (b) Find the value x(14, 0.05). (c) Find the value x(13, 0.99). (d) Find the value x(28, 0.995).arrow_forward
