Answer:the minimum rate is 1 mile per hour.
Step-by-step explanation:
Chanita wants to swim the 21-mile English Channel in 48 hours. Total number of miles that she covered on the first day is 9 miles. Total distance left for her to cover would be
21 - 9 =12 miles.
The next day, she has 12 hours of daylight to complete the remaining distance. Let x represent the minimum rate she has to swim on the second day to complete the distance.
Speed = distance/time
Therefore,
x ≥ 12/12
x ≥ 1
Answer:
The inequality that you have is 
. You can use mathematical induction as follows:
Step-by-step explanation:
For 
we have:
Hence, we have that 
Now suppose that the inequality holds for 
and let's proof that the same holds for 
. In fact,
Where the last inequality holds by the induction hypothesis.Then,
Then, the inequality is True whenever 
.
Answer:
1. True 2. True
Step-by-step explanation:
1. all horizontal lines represent a function.
2. The equation y=2x+1 represents a function.
answer is B) Corresponding angles
The number of days when the season pass would be less expensive than the daily pass is 5 days.
<h3>How many days would the season pass be less expensive?</h3>
The equation that represents the total cost of skiing with the daily pass : (daily pass x number of days) + (cost of renting skis x number of days)
$70d + $20d = $90d
The equation that represents the total cost of skiing with the seasonal pass : cost of season pass + (cost of renting skis x number of days)
$300 + $20d
When the season pass becomes less expensive, the inequality equation is:
Daily pass > season pass
$90d > $300 + $20d
In order to determine the value of d, take the following steps:
Combine and add similar terms: $90d - $20d > $300
70d > $300
Divide both sides by 70 d > $300 / 70
d > 4.3 days
Approximately 5 days.
