A hot air balloon is ascending at the rate of 13 m/s and is 75 m above the ground when a package is dropped over the side. How long does the package take to reach the ground? With what speed does it hit the ground?

you look at the graph and divide your d value by the t value to find the walking rate, if it increase by one the then rate goes down bc you know are walking a second longer to go teh same distance, or the slope of the line on teh graph would be more steeper

just because the increase of price, the actualy supply will increase, but the movement along the supply curve to a higher quantity supplied would be correct

ALGEBRA 1
find the slope using the distance and put the points into the point-slope equation y1 - y= m times (x-x1) so if you have the points (3,4) and the slope is 5 then the equation would look like this: 4-y= 5 (x-3) then distrubute the 5 so its 4-y = 5x -15 then solve it for y

To stop a car, you require first a certain reaction time to begin braking. Then the car slows under the constant braking deceleration. Suppose that the total distance moved by your car during these two phases is 56.7 m when its initial speed is 82.5 km/h, and 24.4 when the ...
