Answer:
I think it is 6/7
Step-by-step explanation:
I am really bad at explaining but I'm not completely sure
Step-by-step explanation:
In the first part, he was travelling with twice the speed, or Vs, for distance
48 - d, for 2 hours.
speed = distance/time
distance = speed * time
First part :
48 - d = 2V * 2
⇒d + 4V = 48
Second part:
d = V * 2
⇒d = 2V
Substitute 2s for d in equation 1.
2s + 4s = 48
6s = 48
s = 8
The speed in the second part is 8 mph.
<u>The speed in the first part is 2s = 2(8) = 16</u>
I hope this helps
I think it is yz but I and not completely sure
Using an linear function, we find that by 2020 only 11% of all American adults believe that most qualified students get to attend college.
-----------------------------------------
A decaying linear function has the following format:

In which
- A(0) is the initial amount.
- m is the slope, that is, the yearly decay.
- In 2000, 45% believed, thus,

- Decaying by 1.7 each year, thus
.
The equation is:

It will be 11% in t years after 2000, considering t for which A(t) = 11, that is:




2000 + 20 = 2020
By 2020 only 11% of all American adults believe that most qualified students get to attend college.
