2 weeks = 14 day
14 * 15 = 210 seconds
210/60=3 hours and 30 minutes or 3.5 hours.
 
        
             
        
        
        
 unequal Triangle 
 If two sides of a triangle are unequal, The angle opposite to the greater side is greater than the angle opposite to less.That is, 
In a triangle ΔABC,
if AC > AB then ∠B > ∠C
 
        
             
        
        
        
Sec is the length of the hypotenuse divided by the length of the adjacent side. 
Meaning divide 20/16
Meaning your secant or sec is 1.25 or 1 1/4
        
             
        
        
        
So the two possible original temperatures would be either -9 or 9.
        
                    
             
        
        
        
Answer:
10.17 seconds
Step-by-step explanation:
substitute y=0 into the equation
0=-16x²+153x+98
 then use the quadratic formula
a = -16
b= 153
c = 98
Substituting values into the Quadratic equation, you get (Round the values to the nearest hundreth):
x₁= 10.17
x₂= -0.60
