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.
Answer:
0.857 miles in 1 hour
Step-by-step explanation:
It is given that,
A crew of highway workers paved 12 mile in 14 hour.
We need to find how much will they pave in 1 hour if they work at the same rate.
14 hours = 12 miles
To find how much they pave in 1 hour, we must divide 12 by 14 as follows :
Hence, they pave 0.857 miles in 1 hour.0.857 miles in 1 hour.
Answer:
176$
Step-by-step explanation:
I think it will be 176$ because he could've been given 1 dollar for each job and he did 24 total jobs so 200 - 24 = 176
(If this answer is wrong I'm sorry because I may not have that much advanced knowledge)
Answer:
Step-by-step explanation:
sum the outcome times the probabilities
5*.5+6*.12+7*.2+8*.08+9*.06+10*.04= 6.2
