Answer:
dcba
Step-by-step explanation:
changed it because i realized it said greatest to least
On the first day the cost is $20
Over the next 5 days the price decreased by 2
So, day 1- $20
Day 2- $18
Day 3- $16
Day 4- $14
Day 5- $12
Day 6- $10
We'll then add them all to find the total over 6 days
$20+$18+$16+$14+$12+$10= $90
Over all six days, the total price is $90
Answer:
B and E
Step-by-step explanation:
The slope has to be 1/2 because the equation in the question is equal to 1/2 so only B and E are parallel

Answer:</h3>
- using y = x, the error is about 0.1812
- using y = (x -π/4 +1)/√2, the error is about 0.02620
<h3>
Step-by-step explanation:</h3>
The actual value of sin(π/3) is (√3)/2 ≈ 0.86602540.
If the sine function is approximated by y=x (no error at x = 0), then the error at x=π/3 is ...
... x -sin(x) @ x=π/3
... π/3 -(√3)/2 ≈ 0.18117215 ≈ 0.1812
You know right away this is a bad approximation, because the approximate value is π/3 ≈ 1.04719755, a value greater than 1. The range of the sine function is [-1, 1] so there will be no values greater than 1.
___
If the sine function is approximated by y=(x+1-π/4)/√2 (no error at x=π/4), then the error at x=π/3 is ...
... (x+1-π/4)/√2 -sin(x) @ x=π/3
... (π/12 +1)/√2 -(√3)/2 ≈ 0.026201500 ≈ 0.02620
