To calculate the volume of a cylinder, we have equation like this: V = πd 2 4 h = πr 2h d is the diameter, r is the radius and h is its height. We can measure the diameter (r = d 2 ) and height directly. To calculate the confidence interval of the volume, we should use the propagation of errors. We use the micrometer screw to measure the diameter. The minimum interval on the screw is 0.01mm. What is the confidence interval for δd and δr?

Answers

Answer:

$\delta d =$ +/- 0.01 mm

$\delta r =$ +/- 0.02 mm

Step-by-step explanation:

$\delta d$ . The error of a quantity directly measured is the uncertainty of the tool used for measuring. So error for diameter is 0.01 mm.

$\delta r$ . The error of a quantity obtained multiplying/dividing a measure by a constant is calculated multiplying/dividing the measure uncertainity by the same constant. Radius is calculated as r=2*d, so we calculate $\delta r$ multiplying the diameter uncertainty by 2 ( $\delta r = 2*0.01=0.02$ ).

$\log (4x - 1) - \log (x + 2) = \log x$
$\log ( (4x - 1)/(x + 2) ) = \log x$
$(4x - 1)/(x + 2) = x$
$4x - 1 = x(x + 2)$
$4x - 1 = x^2 + 2x$
$0 = x^2 - 2x + 1$
$0 = (x - 1)^2$
⇒ $x = 1$

Determine whether (6,4) is a solution of y = 19x - 2.

Answers

Answer:

Not a solution

Step-by-step explanation:

To determine if a pair of coordinates is the solution to an equation, just plug it in.

Given that the equation is:

y = 19x - 2

And the coordinates they give us to evaluate:

(6, 4)

Plug the coordinates in:

y = 19x - 2

4 = 19(6) - 2

4 = 114 - 2

4 = 112

4 ≠ 112

4 is not equal to 112. Therefore this pair is not the solution.

Answer: No, it's not a solution.

Explanation

The point (6,4) tells us that x = 6 and y = 4 pair up together.

Plug those values into the equation. Simplify both sides as much as possible (use PEMDAS). If we get the same thing on both sides, then that point is a solution to the equation.

y = 19x - 2

4 = 19*6 - 2

4 = 114 - 2

4 = 112

We get different values on each side. Therefore, the point (6,4) is not a solution to the equation.

Another approach you could do is graph the equation using a tool like Desmos. GeoGebra works as well. The point (6,4) is not on the diagonal line. Check out the diagram below to see what I mean.

What is 16.403 round to the nearest tenth?

Answers

Well, since there is a 0 in the hundredths place, the 4 in the tenths place would stay the same! Ignore the 3.
Your answer:16.4
I hope this helps!

16.4 is 16.403 rounded to the nearest tenth because tenths are the number right after the decimal point and if the number right after it is 5 or above you round the place above up. If the tenths are below 5 you round down.
