Answer:
Step-by-step explanation:
a) The y-coordinates of points A and B are both -2, so there is no change in the y-value between those points. The x-coordinates differ by 4, so the slope is ...
... slope = (change in y)/(change in x) = 0/4 = 0
b) The y-value is constant at -2 for any value of x, so the equation of the line is ...
... y = -2
For this case we have the following equation:
h (t) = - 12t2 + 36t
When the object hits the ground we have:
- 12t2 + 36t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 3
Therefore, the time it takes the object to hit the ground is:
t = 3 s
Answer:
the time when the object hits the ground is:
t = 3 s
The sum of all the interior angles in a hexagon is 720°, so if you add up all the angles and then take them away from 720, you'll get your answer:
152 + 85 = 237
237 + 85 = 322
322 + 125 = 447
447 + 135 = 582
So 720 - 582 = 138°, which is your answer. I hope this helps!
