Answer:

Step-by-step explanation:
Given:
Each city is exactly 120 miles from the other two.
Average rate from city A to city B = 60 mi/hr
Average rate from city B to city C = 40 mi/hr
Average rate from city c to city A = 24 mi/hr
We need to find the Dale's average rate for the entire trip.
Solution:
First we find the total time and total distance by following way.
Time taken to travel from A to B = 
Time taken to travel from B to C = 
Time taken to travel from C to A = 
So, total time taken = 
Total distance = 120 + 120 + 120 = 360 miles
Using average speed formula.



Therefore, the average rate for the entire trip 
To complete the square of a polynomial, use the term "(b / 2) ^ 2".
In this polynomial, the "b" term is 14.
Plug that in.
(14 / 2) ^ 2
7 ^ 2
49.
The answer is C.
Answer:
2
Step-by-step explanation:
If the polygon or the figures are similar then it is
known that the ratios of their corresponding sides and angles are proportional.
In this item we can derive an equation that is,
<span>
AC/AE = AD/AB</span>
Substituting the known values,
<span>
4/7 = 10/AB</span>
<span>AB from the equation is equal to 70/4 or equal to 17 ½. </span>
Answer:
6x
Step-by-step explanation:
Given that a function f(x) is given as

A) 
Now divide by delta x

B) When delta x tends to 0, this becomes

(NOte: This is the derivative of f(x))
