When exchanging US Dollars (USD) for Philippine Peso (PHP) the number of Philippine Pesos received is directly proportional to the number of US Dollars to be exchanged. If 1,150 USD can be converted into 35,165.85 PHP. Find the constant of proportionality k. k= (If needed, round answer to 3 decimal places.) Using the k from above find the amout of PHP given that you have 1,300 USD to convert. you will receive PHP (If needed, round answer to 2 decimal...
define what it means for two variables to be directly and inversely proportional. Using the variables x and y and the constant of proportionality c, write an equation showing x and y having the defined relationship. Directly Proportional: Inversely Proportional: Reference(s): Please help!!
1a) If the rate of change, W, is inversely proportional to W(x) where W is always greater than 0. If W(1)=25 and W(4)=17, then find W(0) 1b)assume an object's weight, W, is proportional to its height, H. Does it make sense to use differential equations to model the Weight of the object? If so, write the differential equation. If not, explain why 1c)Assume the population, P, of cats in a region is proportional to the area, A, of the region....

Use linear approximation, i.e. the tangent line, to
approximate as follows:Let f(x) = x 6.
The equation of the tangent line to f(x) at x = 2 can be written
in the form y = mx+b
where
is:
and where
is:
Using this, we find our approximation for 1.86is

Find a constant k (in terms of a) so that the function fxx (x,y) = e-(x+u) 0 << oo and 0 < y <a and O elsewhere is a valid joint density function.
The intensity of a light source at a distance is directly
proportional to the strength of the source and inversely
proportional to the square of the distance from the source. Two
light sources, one five times as strong as the other, are 9 m
apart. At what point on the line segment joining the sources is the
intensity the weakest? Write an equation representing the
intensity, I, at a distance, x, from the weaker lightbulb, and with
k as the...
