Hello! I'm just going to post the questions and then a picture with the question and answer choices.

4. Which of the following functions has a rate of change that stays the same?

5.How many real number solutions does the equation have?

6. How many real number solutions does the equation have?

7. Graph the set of points. Which model is most appropriate for the set?
(sorry if you cant see well, had to zoom out to get all of it.)

8. What type of equation will best fit the data below?

This is Unit 4 Lesson 10 Quadratic Functions and Equations Unit Test.

All help is appreciated! ;c

Pete is making decorations for a dinner party. the instructions tell him to use 9 flowers for a medium-sized decoration. complete each statement to adjust the flowers for different-sized decorations based on these instructions.

Find the solution of each of the following.

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
