Answer:
Part a) Option d 
Part b) Option a
Step-by-step explanation:
Part a
if we look at the options given and the data available
Option a) x^4+9 
Putting x= 2 we get (2^4) + 9 =25
Putting x= 3 we get (3^4) + 9 =90 but f(x) =125 so not correct option
Option b) (4^x)+9 
Putting x= 2 we get (4^2) + 9 =25
Putting x= 3 we get (4^3) + 9 =73 but f(x) =125 so not correct option
Option c) x^5
Putting x= 2 we get (2^5)  =32 but f(x) =25 so not correct option
Option d) 5^x
Putting x= 2 we get (5^2)  =25
Putting x= 3 we get (5^3)  =125
Putting x= 4 we get (5^4)  =625
So Option d is correct.
Part (b)
3(2)^3x
can be solved as:
=3(2^3)^x
=3(8)^x
So, correct option is a
 
        
             
        
        
        
Answer:
9ft
Step-by-step explanation:
Use the pythagorean theorem.
15^2 = 12^2 + x^2
solve for x
x^2 = 81
x = 9
