Hello, and thank you so much to anyone viewing this and/or posting to help out. These are two problems in my summer math packet I can't solve of the 156 problems. There are ten total I'm struggling with.
136) For a drag race car that weighs 1500 kilograms, the velocity v (in kilometers per hour) reached by the end of a drag race can be modeled by the function v=24.1(cube root)(p)), where p is the car's power ( in horsepower). Use a graphing calculator to graph the function. Calculate the power of a 1500-kilogram car that reaches a velocity of 220 kilometers per hour. Round to nearest ten.
137) The time t (in seconds) it takes a grandfather clock pendulum to swing back and forth is given by the function t=2π(square root)(r/32)), where r is the length (in inches) of the pendulum. It takes 8 seconds to swing back and forth.
a) How long is the pendulum? Use 3.14 for pi, round to nearest hundredth
b) Find the input to f(x) when the output is -8
