How many solutions exist for the system of equations in the graph? On a coordinate plane, a graph of a circle and a parabola are shown. The circle has a center at (0, 0) and a radius of 8 units. The parabola opens up and goes through (0, 8), has a vertex at (3.5, 2), and goes through (7, 8). one two three four Mark this and return

Use properties to rewrite the given equation. which equations have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p?

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

Question: a) does the given set of points represent a linear function? how do you know? b) assume that the point (-2,4) lies on the graph of a line. what y-values could complete this set of ordered pairs that lie on the same line: (- (hint: there are several correct answ
