Answer:
   (b)  √5
Step-by-step explanation:
The square root of an integer is rational if the integer is a perfect square. You probably know the first few perfect square integers are 1, 4, 9, 16, 25, 36, ...
The integer 5 is not on that list, so its square root will be irrational.
   √5 is irrational
 
        
             
        
        
        
Rule T < - 7, - 8>
=> 
- 7 means shift 7 units to the left
- 8 means shift 8 units down
Therefore, the answer is 7 units to the left and 8 units down

Answer:
h(x) = -16x² + 192x + 208
 784ft
6 sec
13 sec
Step-by-step explanation:
a)
h(x) = -16x² +vx + h
here v represent velocity 
           represent initial height of launch
 represent initial height of launch
        
h(x) = -16x² + 192x + 208
b)
h(x) = -16x² + 192x + 208
here a = -16
         b = 192
         c = 208
x = -b/2a
   = -192/2(-16)
   = 6
plug this value in the equation
h(x) = -16(6)² + 192(6) + 208
       = 784ft
e)
Plug h(x)=0 in the equation
0 = -16x² + 192x + 208
divide equation by -16
x² - 12x - 13 = 0 
Factors
1x * -13x = -13
1x - 13x = -12
Factorised form
x² - 12x - 13 = 0 
x² + x - 13x - 13 = 0 
x(x+1) -13(x+1) = 0 
(x+1)(x-13) = 0
x = -1
x = 13
Since time can not be negative so we will reject x = -1
