An air traffic controller is tracking two planes. To start, Plane A was at an altitude of 700 meters, and Plane B was at an altitude of 424 meters. Plane A is gaining altitude at 16 meters per second, and Plane B is gaining altitude at 22 meters per second. For each plane, write an expression for the altitude of the plane after x seconds. Write an equation to show when the two planes would be at the same altitude.

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

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

there are infinitely many solutions.
