Answer:
   A.  width = x - 4.5
   B.  111 = 2(x + (x -4.5))
Step-by-step explanation:
A. The width is 4.5 meters shorter than x, so is x -4.5.
__
B. The perimeter is twice the sum of length and width. It is 111 meters, so an equation for it could be ...
   111 = 2(x + (x -4.5))

Answer:
Step-by-step explanation:
The given information is expressed as
 Side effect no side effect total
Adult 7 43 50
Children 22 28 50
Total 29 71 100
Probability is expressed as 
Number of favorable outcomes/number of total outcomes
For the probability that an adult has side effects, 
Total number of outcomes = 50
Number of favorable outcomes = 7
Probability that an adult has side effects = 7/50 = 0.14
For the probability that a child has side effects, 
Total number of outcomes = 50
Number of favorable outcomes = 22
Probability that an adult has side effects = 22/50 = 0.44
Therefore, it is more likely that a child has side effects compared to an adult
 
        
             
        
        
        
#2) Use quotient rule

Remember for solving log equations:

#3) Derivative of tan = sec^2 = 1/cos^2
Domain of tan is [-pi/2, pi/2], only consider x values in that domain.
#4 Use Quotient rule
#9  Use double angle identity for tan

This way you can rewrite tan(pi/2) in terms of tan(pi/4).
Next use L'hopitals rule, which says the limit of indeterminate form(0/0) equals limit of quotient of derivatives of top/bottom of fraction.
Take derivative of both top part and bottom part separately, then reevaluate the limit. <span />
