Answer:
11) 4/11
12) -0.2
Step-by-step explanation:
Jo's Mobile Plan:
- Fixed monthly charge = £16
- Monthly 150 free minutes, post that 13p (or £0.13) per minute,
- Monthly 150 free texts, post that 15p (or £0.15) per text
Jo's mobile phone usage details:
- 170 minutes of calls
- 182 texts
Total Charges for Jo = Fixed Monthly Charge + Charges for Calls + Charges for Texts
⇒ Total Charges for Jo = 16 + (170-150) × 0.13 + (182-150) × 0.15
⇒ Total Charges for Jo = 16 + (20) × 0.13 + (32) × 0.15
⇒ Total Charges for Jo = 16 + 2.6 + 4.8
⇒ Total Charges for Jo = 23.4
Hence, Jo should be charged £23.4 for the month.
By critically observing and comparing the functions for the given graphs, we can logically deduce that the widest graph is: "Function 1: y = 0.25x²."
<h3>How to determine the widest graph?</h3>
In Geometry, a graph which has the smallest positive coefficient of x² in absolute value is generally considered as the widest graph while the graph with the largest positive coefficient of x² in absolute value is the narrowest graph.
By critically observing and comparing the functions for the given graphs, we can logically deduce that "Function 1: y = 0.25x²" is the widest.
