Let x be the number of gb used.
Question (1):
Runfast = 10 + 4x
<span>BA&D= 6 + 6x
Question (2):
</span> 10 + 4x = 6 + 6x
2x = 4
x = 2
Both companies will cost the same if you use 2 Gb of data.
BA&D will be cheaper if you use less than 2 Gb of data.
Runfast will be cheaper if you use more than 2 Gb of data.
Answer:
a) The vertex of the graph is 
, b) 
, c) The equation of the parabola is 
.
Step-by-step explanation:
a) The tennis ball experiments a free fall, that is, an uniform accelerated motion due to gravity and in which effects from Earth's rotation and air viscocity are negligible. The height of the ball in time is represented by a second order polynomial. Hence, the vertex of the parabola is the initial point highlighted in graph.
The vertex of the graph is .
b) If we know that , 
and 
, then the value of 
is:
c) The equation of the parabola is .
She received $221.72. If you divide 385.60 in half, because she sold half, you get 192.8. You then multiply that number by 1.15. There you have your answer.
