Answer:
B. 5x^4+5x^3
Step-by-step explanation:
(f.g)(x) = f(x) * g(x)   = 5x^3 * (x+1)
           = 5x^3  * x + 5x^3  * 1
           = 5x^4 + 5x^3 
 
        
             
        
        
        
2+3=5
25/5=5
5x2=10 3x5=15
so the answer is:
£10:£15
        
             
        
        
        
Answer:  a) 0.07910, b) 0.000976, c) 0.7626
Step-by-step explanation:
Since we have given that 
Number of questions = 5
Number of choices = 4
P(getting correct) = 
a) the first question she gets right is the 5th question?
P(getting 4 wrongs answers and one right answer) is given by

b) she gets all of the questions right?
P(all right )= 
c) she gets at least one question right?
1-P(All of them wrong) 

Hence, a) 0.07910, b) 0.000976, c) 0.7626
