x+12=21

Step 1: Subtract 12 from both sides.

x+12−12=21−12

x=9

What is the equation of the parabola in vertex form with vertex (2,-4) and directrix y=-6

Pachacha [2.7K]

Answer:

$y=\dfrac{1}{8}(x-2)^2-4$

Step-by-step explanation:

The directrix y=-6 is parallel to the x axes, so parabola has equation of the form

$(x-x_0)^2=2px(y-y_0),$

where $(x_0,y_0)$ is the vertex of parabola and p is parabola's parameter.

By the definition, $\frac{p}{2}$ is the distance from the vertex to the directrix, so

$\dfrac{p}{2}=2\Rightarrow p=4$

Hence, the equation of parabola is

$(x-2)^2=8(y+4)$

See attached diagram for the graph of parabola and its directrix.

In vertex form this equation is

$y=\dfrac{1}{8}(x-2)^2-4$

The diameter of a standard basketball is 9.5 inches. If the basketballs are covered in rubber, what is the minimum amount of rub

Softa [21]

Answer:

The minimum amount of rubber needed is 1,134 square inches

Step-by-step explanation:

we know that

The surface area of a sphere (basketball ) is given by the formula

$SA=4\pi r^{2}$

we have

$r=9.5/2=4.75\ in$ ----> the radius is half the diameter

$\pi=3.14$

substitute

$SA=4(3.14)(4.75)^{2}=283.385\ in^2$

Multiply by 4 (because are four basketballs)

$283.385(4)=1,133.54\ in^2$

therefore

The minimum amount of rubber needed is 1,134 square inches
