You are measuring the height of a tree. you stand 55 feet from the base of the tree. the angle of elevation from the ground to the top of the tree is 49˚. find the height of the tree to the nearest foot. options : - a. 11 ft. b. 70 ft. c. 63 ft. d. 58 ft. e. none of the above show work!

The answer is C. 63 ft.

Step-by-step explanation

For right-angled triangle, tan=opp side / adj side

tan(49)=height/55

height=55tan(49)=63'

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
