Answer:
- secant slopes: -213.5, -187, -145, -113, -85
- tangent slope: -166
Step-by-step explanation:
A) the slope values you have put in your problem statement are correct. As you know, they are computed from ...
(change in gallons)/(change in time)
where the reference point for changes is P. Using the first listed point Q as an example, the secant slope is ...
(3410 -1275)/(5 -15) = 2135/-10 = -213.5 . . . . gallons per minute
__
B) The average of the secant slopes for points Q adjacent to P is ...
(-187 +(-145))/2 = -332/2 = -166 . . . . gallons per minute
The tangent slope at point P is estimated at -166 gpm.
The answers are a, c, d, e
Answer:
-4, -2, -1
Hope that helps!
Step-by-step explanation:
No. For example,

gives you a 2, which isn't a recurring decimal! You can try this for all sorts of multiples of 9 and you will see that they do not give you recurring decimals. However, there are some, e.g.

which gives you 1.1111111....

The GCF is 2
Pull out 2 from each number:
2(2n + 5)
