Pedro tem um terreno no formato quadrado e área de 20 m². Ele quer construir uma cerca de arame ao redor do terreno. Utilizando uma calculadora descubra a medida do perímetro aproximado desse terreno.

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

15 there is a line that includes the point 0,10 and has a slope of 7/4. what is it’s equation in slope intercept form

Pls brainliest will be awarded if answer is correct
