Answer:
Average speed of the particle is 13 miles per hour.
Step-by-step explanation:
From the given question expression for distance traveled by the particle is
Then fro the time interval (1, 4) we have to calculate the average speed.
At t=1, s=2(1)²+3(1) =2+3 =5 miles
And at t = 4 s=2(4)²+3(4) = 2(16)+12 = 32+12 =44 miles
So displacement of the particle in the time span from 1 to hours.
s = (44-5) = 39 miles
And the times taken = (4-1) =3 hours
From the formula speed = displacement/(time taken for displacement)
V = 39/3 = 13 miles/hour
The linear function for the number of trimmers assembled is:
y = 7 + 4x.
--------------------------------
A linear function has the following format:
In which:
- a is the rate of change.
- b is the fixed amount.
--------------------------------
- In an earlier shift, 7 trimmers had already been produced, thus 7 is the fixed amount, that is,
.
- Diane assembles 4 trimmers per hour, thus the rate of change is 4, that is,
- The <u>amount of trimmers y produced after x hours</u> is given by:
