select answers;
this function can be represented by the quadratic equation f(x)=0.15(x+60)^2
this situation can be represented by the exponential function f(x)=60 x 1.15^x
this function has no x-intercept
after 4 years the value of the investment will be $120.00
after 6 years the value of the investment will be $653.00
after 7.86 years the value of the investment will be 3 times the initial value
after 8 years the value of the investment will be $184.00

Akite is being flown at a 45 angle. the string of the kite is 120 feet long. how high is the kite above the point at which the string is held?

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
