Assume Charles charges $7*3=$21 if he babysits for 2,5 hours (that is 2 and a half hours).
That is we are not considering Charles babysitting exactly 1, 2, 3 or 4 hours, but also in between times.
then we can write the following piecewise function to describe the situation:
f is a function from (0, 4] to {$7, $14, $21, $28}
Answer:
$80
Step-by-step explanation:
4x/2=2x
7x-60
7x-60=2x*2
7x-60=4x
3x=60
x=20
20*4=80
The converse of the statement is
if a rectangle doesn't have four sides the same length, then it isn't a square
Answer:
In programming, a recursive function is a function that calls itself. Recursion is used very commonly in programming, although many simple examples (including some shown in this section) are actually not very efficient and can be replaced by iterative methods (loops or vectorized code in MATLAB).
