A point is moving on the graph of xy=7. When the point is at (4, 7/4), its x –coordinate is increasing at a rate of 1 units per sec. What is the speed of the y-coordinate at that moment and in which direction is it moving?

Would a temperature change affect the refractive index and if so, how?

Select the best explanation from those shown.

1) At higher temperatures, the liquid would evaporate and the refractive index could not be measured accurately.

2) Yes, a decrease in temperature would decrease the refractive index.

3) Yes, a decrease in temperature would increase the refractive index.

4) No, the refractive index is temperature independent.

anyone has any idea?thank you.

I kinda doubt that last one but it doesn't hurt to ask, I guess. I'm just curious as to the rate at which polar ice is melting/sea level is rising. Is there some sort of equation that scientists are using to predict it? I want to know how long it will take before my province ends up underwater xP

You take a surprise quiz in your astronomy class with 8 multiple questions. You estimated that you would have about a 70% chance of getting any individual question correct. What are your chances of getting them all right? Your simulation should use at least 20 runs.

A: 4.28709385
B: 5.6
C: 0.05764801
D: 56
E: 2,097,152

how do i determine the period, vertical shift, phase shift, domain, range, and asymptote of these problems:

*by pi i mean 3.14...... the n with the swigly line at the top i dunno how to type it on the keyboard

1. y = 1 - tan ( x/2 - pi/8 )

2. y = 3 + 2 csc ( x/2 - pi/3 )

3. y = 1 + cot ( 3x + pi/2 )

4. y = 2 - sec ( 2x - pi/2 )

proportions. The bell with the lowest pitch is tuned to
pitch A, the next bell is tuned to A-sharp, then B,
C, C-sharp an so on to cover entire chromatic scale
of notes. Poor fella has only 1lb of silver.

How much siver should the jeveler use
for the largest bell in the set?
