The result of multiplying 2 by x plus y times 3 plus 5 times z is equal to 10.
2x + y * 3 + 5 * z = 10
2x + 3y + 5z = 10
or
2 (x + y * 3 + 5 * z) = 10
2x + 2y + 6 + 10 + 2z = 10
2x + 2y + 16 + 2z = 10
Can someone please check this for me and tell me which way is right? I forgot how to do...
Homework Statement
At the He-Ne laser wavelength (L= 632.8 nm) the refractive indices of crystal quartz are n o = 1.54264 and n e = 1.55171 calculated from its Sellmeier equation. The laser is incident from the air onto the surface of crystal quartz at an angle of incidence of 45 degrees...
I have no idea how to do this or where to start. Can someone please help me?
Problem 4.4- Suppose n o and n e are given. In (a) you only need to find the magnitude of the group velocity. Problem #2 in HW 10 may be helpful. You can also directly use the definition of group velocity, i.e., v g =...

The following error propagation (sample calculations) consists of the ‘simple’ methods
outlined in lab appendix (pages A7-A9). This method yields uncertainties which are
slightly high, but still gives ‘reasonably good values’.
For added/subtracted quantities, the uncertainties are...
In response to your question, I am not sure what they have in common. I don't understand how to do the problem and this is how come I am asking for help.
I added the numbers together and that is how I got it. I don't know how to convert to centimeters or meters. No, I don't know how to combine uncertainties from multiple sources.
response to uncertainties
My textbook isn't very good and doesn't give an explanation about combining uncertainties. As for in class, my instructor doesn't explain the steps and there aren't any example given about the uncertainties. All it mentions is the definition of an uncertainty and the...
d1 = 2.53 cm +/- .05 cm
d2 = 1.753 m +/- .001 m
0 = 23.5 degrees +/- .5 degrees
v1 = 1.55 m/s +/- .15 m/s
Using the measured quantities above, calculate the following. Express the uncertainty calculated value.
a = 4 v1^2 / d2
a = 4 (1.55 m/s +/-.15 m/s)^2 / 1.753 m +/- .001 m
a = 6.8 m/s...
Why is the equation y = (x - 2) ^2 - 9 the one out of all three equations listed below:
y = (x - 5) (x + 1)
y = x^2 - 4x - 5
y = (x - 2) ^2 - 9
the one from which the x-intercepts are most easily determined? Can you explain this?
Make up an equation that satisfies the given conditions: must have x-intercepts at (-1, 0) and (2, 0). It must also have a y-intercept at (0, 4).
Is it correct to say that the equation with x-intercepts would look like this:
y = (x - 2) (x + 1)How do you factor the y-intercept?
These 3 equations all describe the same quadratic function. What are the coordinates of the following points on the graph of the function? From which equation is each point most easily determined?
y = (x - 5) (x + 1)
y = x ^ 2 - 4x - 5
y = (x - 2) ^ 2 - 9
X-intercept, what are the points...
re: Parabola standard form of equation at x=-5
I have two different formulas for using the conic section of a parabola, can someone please tell me which is correct for this type of problem?
The first one is as follows:
Type: Parabola
General Equation: y = a (x-h)^2 + k
Standard Form: (x - h)...
