Cecile buys a move to watch on her phone, but she's worried about the amount of storage space downloading it will take up. She starts the download and notices it will download at a constant rate. After 3 minutes, she checks her phone and sees that she has 2,345 MB (megabytes) of space available. She checks her phone after 7 minutes and notices that she now has 2,105 MB of space available. a. How many MB of available storage are being filled by the movie per minute?

b. How much space was available on her phone before the download started?

c. Suppose the download lasted for a total of 19 minutes. How much available storage remains after downloading the movie?​

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. you notice the rainbow is the shape of a parabola. the equation for this parabola is y = -x2 + 36. graph of a parabola opening down at the vertex 0 comma 36 crossing the x–axis at negative 6 comma 0 and 6 comma 0. in the distance, an airplane is taking off. as it ascends during take-off, it makes a slanted line that cuts through the rainbow at two points. create a table of at least four values for the function that includes two points of intersection between the airplane and the rainbow. analyze the two functions. answer the following reflection questions in complete sentences. what is the domain and range of the rainbow? explain what the domain and range represent. do all of the values make sense in this situation? why or why not? what are the x- and y-intercepts of the rainbow? explain what each intercept represents. is the linear function you created with your table positive or negative? explain. what are the solutions or solution to the system of equations created? explain what it or they represent. create your own piecewise function with at least two functions. explain, using complete sentences, the steps for graphing the function. graph the function by hand or using a graphing software of your choice (remember to submit the graph).
