What interval includes all possible values of x, where –3(6 – 2x) ≥ 4x + 12?

Pavel [41]

The solution to the problem is as follows:

solve for x :

−3(6−2x)≥4x+12

 −18+6x≥4x+12

 2x≥30

 x≥15

 So the answer is D ) 15 to +infinity


I hope my answer has come to your help. God bless and have a nice day ahead!

The cross section of a parabolic reflector has a vertical axis of symmetry with its vertex at (0,0) . The focus of the reflector

Paha777 [63]

Answer:

The depth of the reflector is 0.84 feet

Step-by-step explanation:

(See the figure below)

The equation of a parabola centered at the origin with an axis of symmetry on y-axis is:

$x^{2}=4py$ (1)

With p the distance from the origin to the focus using p=6, the equation (1) of the parabola becomes:

$x^{2}=4(6)y=24y$ (2)

Note that the point B is on the parabola, so this point should satisfy the parabola equation (2) that allow us to use the value x=4.5 to find the y value associated to it, that it is the depth (h) of the reflector:

$(4.5)^{2}=24y$ , solving for y
