Answer:

Step-by-step explanation:
You have the following function:
(1)
In order to find the zeros of the function you equal to zero the equation (1), and then you solve for θ:

Then, there are infinite zeros for the function of the equation (1), because n has infinite positive integers values.
Answer:
At the time of launch height of the object was 60 meters.
Step-by-step explanation:
An object was launched from a platform and its height was modeled by the function,
h(x) = -5x² + 20x + 60
Where x = time or duration after the launch
At the time of launch, x = 0
So, by putting x = 0 in this equation,
h(0) = -5×(0) + 20×(0) + 60
h(0) = 60
Therefore, at the time of launch height of the object was 60 meters.
1+1+1 is 3. And you have 1/3+1/3+1/3=3/3=1. So you end up with 3+1=4. So yes
