I am confused on how to go about solving this question. I tried plugging in the values of x and y into the equations but dont know what to do from there

We need at least 10 more requests to produce the answer.

The more requests, the faster the answer.
Determine the values of h and k for which the graph of y=he^kx passes through the points (1,4) and (4,32).
Calculate the distance from the center of the Earth of Geostationary or Geosynchronous orbit. G = 6.67 x 1—11 N*m2/kg2 and the mass of the Earth = 5.98 x 1024 kg. (5 points) What kind of problem is this? If there is any other hidden information what is it? For what variables do I have numbers and for what am I solving? I am interested in equations with what variables? List all relevant equations here. Highlight what you know by...
How do I determine the per-worker production function, y = f (k) of the production function Y = K1/3 L2/3? I know I must divide both sides by L, labor. This gives me y = (K1/3L2/3)/L. Where do I go from here?
A laser produced a diffraction pattern on a screen. The graph
below shows the intensity of the signal as a function of y. Assume
that the slit is 0.050 mm wide, located 0.80 m from the screen.
What is the frequency of the laser? Completely solve algebraically
before inserting any numerical values.
I know the answer is f = 4.8x10^14 Hz but I dont know how to get
it with these equations:

Which of the following has no absolute extrema? (select all that apply) a: y = -19tan(x) b: y = -19x^2 c: y = 19 d: y = -19cos(x) I am pretty confused on local/absolute max/min and the extrema it would be great if you could be able to explain a bit about it too. I can't figure out this practice question. Thanks for your help.
