Explain why the point (-8,-2) on the graph has no meaning in terms of volume and edge length

Determine the initial value of the quadratic relation y=7x²+2x-32. Enter a numeric value only.

Kevin threw a ball straight up in the air. The function y = -5(x- 2)? + 20 describes the ball's height, in metres, t seconds after Kevin threw it. What are the coordinates of the vertex? a. (-5, 2) с. (20, 2) b. (2,20) d. (-5, 20)

3 The given graph shows the relation between the area of water (y, in sq. miles) and the area of land (x, in sq. miles) on Mars. Write an equation for the same. 56 42 28 y = 14 0. 100 200 300 400 Area of land (sq. miles) Area of water (sq. miles)

Which sentence below best describes the relation between square footage and rent? O A. There appears to be a linear relation between square footage and rent. B. There appears to be a quadratic relation between square footage and rent. O C. There does not appear to be any relation between square footage and rent. (b) Based on your response to part (a), find either a linear or quadratic model that describes the relation between square footage and rent. Which equation below best describes the relation between square footage and rent? O A. R=0.976x² +0.166x+893 O C. R=0.166x² +0.000509x + 1214 E. R = 0.000509x + 1214 G. There is no relation. B. R=893x + 0.976 D. R=0.000509x² +0.166x + 1214 R=0.976x + 893 F. (c) Use the model you selected in part (b) to predict the rent of an apartment in the section that is 850 square feet. The predicted rent of an apartment with 850 square feet is about $ (Use the answer from part (b) to find this answer. Round to the nearest whole number as needed.)
