Melinda and genevieve live in houses that are next to each other.
melinda lives in a two-storey house, and genevieve lives in a
bungalow. they like to throw a tennis ball to each other through their
open windows. the height of a tennis ball thrown from melinda to
genevieve, f(x), in feet, over time, x, measured in seconds is modelled
by the function
f(x) = -5x2 + 6x + 12
what are the domain and range of this function if genevieve catches
the ball 4 ft above the ground? draw a diagram to support your
answer.

If the measure of angle 1 is 110 degrees and the measure of angle 3 is (2 x+10 degree), what is the value of x?

Questions 9-10. use the table of educational expenditures to answer the questions. k-12 education expenditures population indiana $9.97 billion 6.6 million illinois $28.54 billion 12.9 million kentucky $6.58 billion 4.4 million michigan $16.85 billion 9.9 million ohio $20.23 billion 11.6million 9. if the amount of k-12 education expenses in indiana were proportional to those in ohio, what would have been the expected value of k-12 expenditures in indiana? (give the answer in billions rounded to the nearest hundredth) 10. use the value of k-12 education expenditures in michigan as a proportion of the population in michigan to estimate what the value of k-12 education expenses would be in illinois. a) find the expected value of k-12 expenditures in illinois if illinois were proportional to michigan. (give the answer in billions rounded to the nearest hundredth) b) how does this compare to the actual value for k-12 expenditures in illinois? (lower, higher, same? )
