Answer:
86.23
Step-by-step explanation:
$5.29*16.3=86.227
86.227 exact -> 86.23 real
By applying <em>algebraic</em> handling, <em>exponential</em> and <em>logarithm</em> properties, we conclude that the equation of the time of flight (T) is .
<h3>How to clear a variable within an exponential equation </h3>
In this question we must clear the variable of time of flight (T) by means of <em>algebraic</em> procedures. <em>Exponential</em> expressions are <em>trascendental</em> functions, these are, expressions that cannot be described algebraically:

Answer:
Clarissa will take 10 hours by herself
Step-by-step explanation:
Let s = time for shawna
s-5 = time for clarissa
The formula for determining the time is
1/a + 1/b = 1/c where a and b are the times alone and c is the time together
1/s + 1/(s-5) = 1/6
Multiply each side by 6s(s-5) to clear the fractions
6s(s-5) ( 1/s + 1/(s-5)) = 1/6 *6s(s-5)
Distribute
6(s-5) + 6s = s(s-5)
Distribute
6s -30 +6s = s^2 -5s
Combine like terms
12s -30 = s^2 -5s
Move everything to the right
0 = s^2 -5s -12s +30
0 = s^2 -17s +30
Factor
0 = ( s-15) (s-2)
Using the zero product property
s-15 =0 s-2 =0
s =15 s=2 ( This is not a reasonable answer since it is less than the time together)
s=15
s-5 = 10
