I think its C. 7x3 = 21. 7x18 = 126. 9x7 = 63
If you all that the answer its 210. If you estimate what that little part above the farthest to the right shape, I'd say its near 18 to 21. Then add 210 with either numbers 18 through 21, it would be close to 227 square meters.
Answer:
y = 12x/5 - 39/5.
Step-by-step explanation:
The equation of the straight line is given by the following formula:
(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1); where (x, y) is the general point, (x1, y1) is the first point on the line, and (x2, y2) is the second point on the line.
Given that (x1, y1) = (2, -3) and (x2, y2) = (7, 9):
(y - (-3))/(x - 2) = (9 - (-3))/(7-2).
(y + 3)/(x - 2) = 12/5.
Cross multiplying:
5*(y + 3) = 12*(x - 2).
5y + 15 = 12x - 24.
5y = 12x - 39.
y = 12x/5 - 39/5.
This the equation of the line in the y = mx + c form!!!
Answer:
about 151 feet
Step-by-step explanation:
The height of the ball at a time of 3.1 seconds is given by Charlize's equation as ...
h(3.1) = -16(3.1)^2 +3 = -150.76 . . . feet
The well is about 151 feet deep.

<em>Comment on this measurement</em>
The speed of sound is sufficiently slow that it will make a difference in the time Charlize records. She would get a more accurate measurement if she were able to <em>see</em> the ball hit bottom.
