Hi there! 5 bottles of water for $3 would make $0.60 per bottle. 0.6 * 15 = 9. That means 15 bottles of water should equal $9, but instead it is $8. Based on that, no. The costs for bottles of water is not proportional to the numbers sold. Basically, you can divide to find unit prices and multiply the number of another item to see if the numbers are proportional.

The table below shows the distance d(t) in feet that an object travels in t seconds: t (seconds) d(t) (feet) 1 15 2 60 3 135 4 2
storchak [24]

Answer:


Step-by-step explanation:

Answer:


Option B is correct


The average rate of change of d(t) between 2 second and 4 second is; 90 ft/s


and it represents the average speed of the object between 2 seconds and 4 seconds.


Step-by-step explanation:


Average rate of change of function is defined as the ratio of the difference in the function f(x) as it changes from a to b to the difference between a and b. Then, the average rate of change is denoted as A(x).




As per the given statement, the distance d(t) is in feet and t is the time in second.


To find the average rate of change of d(t) between 2 seconds and 4 seconds.


From the table we have;


at t = 2 , d(2) = 60


and


at t =4 , d(4) = 240.


Then, by the definition of average rate of change ;


=


Simplify:




therefore, the average rate of change of d(t) between 2 second and 4 second is; 90 ft/s and it represents the average speed of the object between 2 seconds and 4 seconds.

avanturin [10]

Answer:

1. 88 - b

Since there is 88 birds and a few of them flew away. You know b represents the amount of birds present.

2. 73 + d

Since he is earning d (amount of dollars) so what you have to do is add the amount of dollars, d, to the orginial amount, which is 73.

3. 23 x g

Since Kurt has 23 miles. If he drives 23 miles to a gallon and we have g gallons then we would multiply to find how far he can drive.

expeople1 [14]

Answer:

4.1 calls

Step-by-step explanation:

The number of calls (c) that Roger expects to get as a function of how many inches of snow fall (s), is described by the following linear model:

c(s)=0.8s+0.29

Therefore, when s = 4.7 inches, the number of service calls that Roger expects is:

c(4.7)=0.8*4.7+0.29\\c(4.7)=4.05\ calls

Rounding to the nearest tenth, Roger will get about 4.1 calls.
