What is the error due to using linear interpolation to estimate the value of sinxsin⁡x at x = \pi/3? your answer should have at
Bad White [126]
<h3>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

City buses have an average of 1400 daily riders. During a gas shortage, the average number was 1554. What percent did the averag
I am Lyosha [343]

Answer:

11%

Step-by-step explanation:

<em>Percentage increase = (New average- previous average)/previous average x 100</em>

<em>New average: 1554</em>

<em>Previous average: 1400</em>

Percentage increase = (1554-1400)/1400 x 100

Percentage increase = 154/1400 x 100

Percentage increase = 0.11 x 100

Percentage increase = 11%

Therefore, the average increased by 11%.

Jim gets a $20 allowance per week plus $25for every lawn he mows. If he made $345 in one week, how many lawns did he mow?
vichka [17]

This week the number of lawns "times" 25 and his allowance = $345

Therefore...

25x + 20 = 345

      - 20     -20

25x         = 325

Now divide both sides by the coefficient (25)... and that will be the number of lawns he mowed.

Hope this helps!

What does x equal? <br><br><br> This question is found on Khan academy.
Sauron [17]

Answer:

Hi there!

The correct answer is 95°

Step-by-step explanation:

Okay if you look at the picture, 95 degrees' supplementary angle is 85 degrees. A supplementary angle means it adds up to 180°. So that means the angle that is supplementary to 85 is 95. **Keep in mind since they did not tell that the sides are parallel you cannot assume that 95° and angle x° are vertical so this is the safest way to solve the problem**
