The area of the rectangle is 4x2, what does the coefficient 4 mean in terms of the problem? a the width is 4 times the length b the length is 4 times the width c the total area of the square is 4 d the length is 4 (the rectangle has a width of x and a length of 4x, i can't provide the rectangle so you have to draw your own)

How long would it take for a ball dropped from the top of a 576-foot building to hit the ground? round your answer to two decimal places.

What is the first step of an indirect proof of a number that is divisible by two

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60
