Answer:
Option B (1,10)
Step-by-step explanation:
we have

we know that
If a ordered pair is on the graph of f(x) then the ordered pair must satisfy the function f(x)
<u><em>Verify each case</em></u>
case A) (0,0)
For x=0

Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is not on the graph of f(x)
case B) (1,10)
For x=1
Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is on the graph of f(x)
case C) (0,10)
For x=0

Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is not on the graph of f(x)
case D) (10,1)
For x=10

Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is not on the graph of f(x)
To determine the number of days that an employee work in a week, we simply use dimensional analysis and multiplying the number of works per week with the number of weeks in total for a year. That is,
employee works = (5 days per week)(49 weeks per year)
=245 days
The x-values are the heartbeat(s) and the y-values are the time(s)
<h3>How to determine the x and y values?</h3>
The variables are given as:
Time(s) and Heartbeat(s)
As a general rule, the action that is being done is the independent variable.
The action here is the heartbeat.
So, the x-values are the heartbeat(s) and the y-values are the time(s)
A possible value of this is;
x = 100, y = 60 seconds
So, the ordered pair is (100,60)
When represented as ratio, we have;
Ratio = 60/100
Simplify
Ratio = 0.6 heartbeat per second

Answer:
4cos4x
Step-by-step explanation:
let's use cos
amplitude=4
period=pi/2
2pi/x=pi/2
x=4
no phase shift
y=4cos4x

She should chose the $9 because it is cheaper ;)
