Answer:
the first formula
Step-by-step explanation:
the graph is y=cosx and cosx=sin(x+90)
The equation is actually

. Free fall is always -16t^2 as the position function. We are looking for how long it takes the object to hit the ground. In other words, the height of an object is 0 when it is laying on the ground, so how long (t) did it take to get there? We will then set that position equal to 0 and solve for t.

. If we subtract 1437 from both sides and divide by -16, we have

. Taking the square root of both sides gives us, rounded to the nearest tenth, t = 9.5 or t=-9.5. The 2 things in math that will never EVER be negative are time and distance/length, so -9.5 is out. That means that it took just about 9.5 seconds for the object to fall to the ground from a height of 1437 feet when pulled on by the force of gravity.
Answer:
Image result for A triangle has two angles that are 33 degrees and 54 degrees. What is the third angle?
If you add all three interior angle measures together in a triangle it will always equal 180°.. To find a third angle you will subtract the sum of the two given angles from 180°.
