An airplane with a speed of 160 knots is headed east while a 24-knot wind is blowing from 240°. find the ground speed to the nearest tenth of a knot.

139.7 knots

156.4 knots

181.2 knots

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

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

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

c. 1,233 miles
