The Cycle Shop sells bicycles and unicycles. Crazy Larry was supposed to do inventory over the weekend. Larry wrote that the total amount of inventory in the shop was 34 cycles; some were bicycles and some were unicycles. He also
counted the total amount of wheels on the cycles. There were 52 wheels. Of the 34 cycles, how many were bicycles and
how many were unicycles?

Tori examined the pattern of exponents in the table. based on the pattern, which statements are true? check all that apply.

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

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^x
