Find the value of x to the nearest tenths. the figure is not drawn to scale.
x = 15.7
x = 4.4
x = 13.9
x = 1.9

Option A is correct

Value of x to the nearest tenths is 15.7 units

Step-by-step explanation:

Angle bisector theorem states that a triangle divides opposite sides in two segments that is proportional to the other two sides.

In given figure:

Labelled the figure.

By Angle bisector theorem:

here, BD = 7.8 units, DC = 8.3 units , AC = x units and AB = 14.8 units

Substitute these values we have;

By cross multiply we have:

Simplify:

7.8x = 122.84

Divide both sides by 7.8 we have;

x = 15.748717

Therefore, the value of x to the nearest tenths is 15.7 units

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
