The process of finding which prime numbers you need to multiply together to get a certain number. ex: 21=7x3 20=2x2x5
Answer:
(a)
(b) 4 miles
Step-by-step explanation:
Given:
The sequence of run is an arithmetic sequence.
Miles traveled on day 1 = 1 mile
Miles traveled on day 7 = 2 miles
(a).
Explicit formula for an arithmetic sequence is given as:
Here,
So,
Therefore, the explicit definition of the above sequence is given as:
Where, is the miles covered on day.
(b)
In order to find the distance covered by her on day 19, we plug in 19 for n in the above formula. This gives,
Therefore, the number of miles covered by her on day 19 is 4 miles.
Answer:
1.97 feet

Step-by-step explanation:
<em>Hope</em><em> </em><em>this</em><em> </em><em>will</em><em> </em><em>help</em><em> </em><em>u</em><em>.</em><em>.</em><em>.</em><em>.</em>
The unit rate is another way of saying speed, so we divide the distance over the time. We can pick on any row
If we pick row 1, then, speed = distance/time = 90/2 = 45
Row 2 says the same thing: 135/3 = 45
So does row 3: 225/5 = 45
and so on
Because the speed is 45 mph, the unit rate is 45 miles in one hour. The term "unit" implies how much distance can be covered in one unit of time, in this case 1 hour.
You have the correct answer. Nice work.
