<span> x | f(x)
25 | 2
125 | 3
625 | 4
From my research, the above table belongs to the question. The values in x show increasing exponential values of 5, where:
5^2 = 25
5^3 = 125
5^4 = 625
As for the case of f(x), they are the values of the powers. So the logarithmic function that would explain the values of x and f(x) would be:
A base-5 function:
</span><span>f(x) = log5 x</span>
To make x^2 + 2x a perfect square we need to add the term { 2 / (2*1) }^2
which equals 1.
Add 1 to both sides: x^2 + 2x = 8
add 1 to both sides: x^2 + 2x + 1 = 8 + 1 (x + 1)^2 = 9
Take square root on both sides: x + 1 = +/- 3 x = +3 - 1 or x = -3 - 1 x = 2 or x = -4
is the question set up -13=m-5 or....
$75
If the fixed cost is $15, it can be removed from the two hour charge to give the charge of ONLY two hours, which is $150.
This means the hourly charge is $150÷2, which is $75
