In the graph, for x on the interval [-7,6), the function y=0
[ ] represents the greatest integer than x without going over
In the interval [-7,6) the value of the greatest integer function is -7
To get y=0 we must add 7
Then the graph is y=[x]+7
Answer: Option A. y=[x]+7
Answer:
The amount after 10 years is $187.57148
Step-by-step explanation:
we are given
amount deposited is $75
so, P=75
time is 10 years
so, t=10
9.6% compounded annually
so, r=9.6%
r=0.096
now, we can use formula
now, we can plug value
we get
So,
The amount after 10 years is $187.57148
Answer:
C. (2, 6] hour jobs cost $100
Step-by-step explanation:
Let's consider each of these statements in view of the graph:
- A cleaning time of 2 hours will cost $100. -- The closed circle at (2, 50) tells you the cost of a 2-hour job is $50, not $100.
- A cleaning time of 6 hours will cost $150. -- The closed circle at (6, 100) tells you the cost of a 6-hour job is $100, not $150.
- Cost is a fixed rate of $100 for jobs requiring more than 2 hours, up to a maximum of 6 hours. -- The line between the open circle at (2, 100) and the closed circle at (6, 100) tells you this is TRUE.
- Cost is a fixed rate of $200 for jobs that require at least 6 hours. -- "At least 6 hours" means "greater than or equal to 6 hours." The closed circle at (6, 100) means a 6-hour job is $100, not $200.
