Answer:
Step-by-step explanation:
Given

Find f(0)
From the piecewise function, we have the following as values of f(x):
If
If
f(0) implies that and
So, we make use of the first function, which is:
Substitute 0 for x in
So, the expression becomes
<em></em>
<em>Hence, the value of f(0) is 14</em>
Answer:
Step-by-step explanation:
See the attachment for derivation of the equation.
y = -(6/7)x + 20 6/7
The y-intercept of the equation is 20 6/7, which means there is 20 6/7 hours of setup time required. When Anna arrives, she has not yet done any setup, so she would not have done any work yet.
In any event, the graph does not tell us how much time Anna really worked. Did Anna spend 6 or 9 hours on the setup? We don't know.
Answer:
the number of diagonals can be found by n *n minus 3 by 2
a) the number of all possible diagonals drawn for having 7 side = 14 diagonals
b) the number of all possible diagonals drawn for having 10 side=35 diagonals
Percent discount = (original price - sales price) / original price
1250 - 900 = 350
350/1250 = 0.28
The percent discount is 28%.
