a) 9/212 = #mph
b)0.000142045 Miles / 0.000277778 hours = # mph
Step-by-step explanation:
a) 9/212 = #mph
b)
1)9 inches divide the length value by 63360 is 0.000142045 Miles
2) 1 hour 3600 seconds in ones hour so 1/3600 =0.000277778
3) take miles/hour
0.000142045 Miles / 0.000277778 hours = # mph
If the pattern continues, so that each term is separated by a distance of 3, then the sequence is given by the recursive rule

From this definition, we can write
in terms of
:




and so on, up to

(notice how the subscript on <em>a</em> and coefficient on 3 add up to <em>n</em>)
or

Answer:
Solution is 
Step-by-step explanation:
Given Differential Equation,
...............(1)
We need to solve the given differential equations using undetermined coefficients.
Let the solution of the given differential equation is made up of two parts. one complimentary solution and one is particular solution.

For Complimentary solution,
Auxiliary equation is as follows
m² - 2m + 1 = 0
( m - 1 )² = 0
m = 1 , 1
So,

Now for particular solution,
let 


Now putting these values in (1), we get






Therefore, Solution is 
The formula for the surface area of cone is:
Surface Area of Cone = π * r * l + π * r^2 , where l = slant height
Substituting the given values:
282.74 ft^2 = 3.14 * 5 ft * l + 3.14 * (5 ft)^2
<span>l = 13 ft</span>
