Answer:
60 miles
Step-by-step explanation:
let d = distance to the lake
Using:  time = distance ÷ speed
Create expressions for the time it takes for each journey:
Drive:  
Walk:   
If total time = 17 hours






Therefore she walked 60 miles
 
        
                    
             
        
        
        
Answer:
The answer is 8.3 bar notation.
Step-by-step explanation:
 2 1/2 into improper is 5/2
3 1/3 into improper is 10/3
Now Multiply
5/2 x 10/3 is 300/36
Now Reduce.
25/3 = 8.3 bar notation

The inverse of the function x^7 is x^-7 and it is also a function.
An inverse function or an anti function is defined as a function, which can reverse into another function.
A standard method to find inverse of a function is to set y=f(x)
let y= f(x)=x^7
thus
 ![\sqrt[7]{y}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7By%7D) =x
=x
thus  (y)=
(y)=![\sqrt[7]{y}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7By%7D)
thus ![f^{-1} (x)=\sqrt[7]{x}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%20%28x%29%3D%5Csqrt%5B7%5D%7Bx%7D)
(To verify this if a function is inverse or not we are required to check for the identity)
f( (x))=
(x))= (f(x))=x
(f(x))=x
Therefore, The inverse of the function x^7 is x^-7 and it is also a function.

Answer:
2
Step-by-step explanation:
loge(x) is ln(x)
f(x) × ln(x)
Differentiate using product law
[ln(x) × f'(x)] + [(1/x) × f(x)]
x = 1
[ln(1) × f'(1)] + [(1/1) × f(1)]
(0 × 4) + (1 × 2)
0 + 2
