Let be the population of a community. The rate R (per day) at which a rumor spreads in the community is jointly proportional to the number of people who have already heard the rumor and the number (P-N) of people who have not yet heard the rumor
A rumor about the president of a college is spread in his college community of 24,000 people. Five days after the rumor started 1000 people had heard it, and it was spreading at the rate of 69 additional people per day Complete
part (a) through (d)
(a) Write an equation relating R and with k as the constant of variation
An equation with the given information is R=?

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
