Domain is [-10,∞) 
2 is included , only at x=2 new function begins
Range is the values of y , so range  is [-7]∪[-4,6
I think, it should be  like this.
        
             
        
        
        
Answer:
60° =  radians
 radians
Step-by-step explanation:
To convert from degrees to radians
radian measure = degree measure × 
Thus 60° in radian measure
= 60 ×  ( divide ( cancel) 60 and 180 by 60 )
 ( divide ( cancel) 60 and 180 by 60 )
= 
 
        
             
        
        
        
The balloon reaches a height of 7 feet at 0.1 seconds and 2.13 seconds 
<h3>How to determine the time the balloon is at the height?</h3>
The equation of the function is given as
h(t)= -16t^2 + 35t + 5
The above equation is a quadratic equation
When the balloon is at a height of 7 feet, we have
h(t) = 7
So, we have the following equations
h(t)= -16t^2 + 35t + 5
h(t) = 7
Next, we plot the equations on a graph (see attachment)
The equations intersect at 
t = 0.059 and t = 2.129
Approximate
t = 0.1 and 2.13
Hence, the times are 0.1 seconds and 2.13 seconds
