a spherical container with a radius of 4 ft is filled with gas that costs$12 per cubic foot what is the total value of the gas i

Mashcka [7]

The spherical container has a radius of 4ft (where ft represents feet)

Its filled with gas that costs $12 per ft³

The value of gas in the container = ?

The volume of a sphere = 4/3 $\pi$ r³

The volume of the container = 4/3 × $\pi$ × 4³ ft³

One cubic foot = $12

4/3 × $\pi$ × 64 = How much?

Cross multiplying gives:

4/3 × $\pi$ ×64 × $12 = $3216.99 (Rounded up to nearest one cent)

The slope for is JK 1/3 , the slope of LK is -2 , the slope of ML is 2/5 , and the slope of MJ is 3/2 . Quadrilateral JKLM is not a parallelogram because neither pair of opposite sides is parallel

Further explanation:

Given vertices are:

J(−4, 1) , K(2, 3) , L(5, -3) , and M(0, −5) .

We have to find the slopes before concluding any result

The formula for slope is:

$m=\frac{y_2-y_1}{x_2-x_1}$

So:

Slope of JK:

$m_1=\frac{3-1}{2-(-4)}\\=\frac{2}{2+4}\\=\frac{2}{6}\\=\frac{1}{3}$

Slope of LK:

$m_2=\frac{-3-3}{5-2}\\=\frac{-6}{3}\\=-2$

Slope of ML:

$m_3=\frac{-3-(-5)}{5-0}\\=\frac{-3+5}{5}\\=\frac{2}{5}$

Slope of MJ:

$m_4=\frac{1-(-5)}{-4-0}\\=\frac{1+5}{-4}\\=\frac{6}{-4}\\=-\frac{3}{2}$

As the slopes of all sides are different, the given quadrilateral is not a parallelogram because in order for the quadrilateral to be a parallelogram the opposite sides have to be parallel i.e. have equal slopes and there are no sides with equal slopes.

Find the midpoint of the line segment with the given endpoints. (-3,-7) and (3,0)

Crank

The coordinates of the midpoint:
$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$
x₁,y₁ - the coordinates of one endpoint
x₂,y₂ - the coordinates of the other endpoint

$(-3,-7) \\
x_1=-3 \\ y_1=-7 \\ \\
(3,0) \\
x_2=3 \\ y_2=0 \\ \\
\frac{x_1+x_2}{2}=\frac{-3+3}{2}=\frac{0}{2}=0 \\ \\
\frac{y_1+y_2}{2}=\frac{-7+0}{2}=\frac{-7}{2}=-3.5 \\ \\
\boxed{(0,-3.5)} - \hbox{the midpoint}$

There really isn’t a possible answer since there is not enough information given. Not from what I have learned so far at least, but using common sense, and the process of elimination I would say 30
