Given, (0,−2).
Since the x-coordinate is 0, the point clearly lies on y-axis.
Also, the y-coordinate −2 being negative, the point lies on the negative y-axis.
The complementary angle of 12 degrees, is 78 degrees.
Complementary angles are angles that when added together have an end result of 90 degrees. So, to find the answer, simply subtract 12 from 90. Thus making the answer 78 degrees.
I hope this helps!
Answer:
427 feet.
Step-by-step explanation:
Answer:
5 seconds
Step-by-step explanation:
When the ball returns to its original height, it will be 96 ft from the ground. That means we want to solve for t ...
h(t) = 96
96 +80t -16t^2 = 96
16t(5 -t) = 0 . . . . subtract 96 and factor
This equation is true for t=0 and for t=5.
After 5 seconds, the ball will pass the top of the building on the way down.
