What is the volume of a sphere with a radius of 6 mm?

Mrrafil [7]

Answer:

$V = 904.779\,mm^{3}$

Step-by-step explanation:

The volume of a sphere can be determined by using the following formula:

$V = \frac{4\pi}{3}\cdot r^{3}$

$V = \frac{4\pi}{3}\cdot (6\,mm)^{3}$

$V = 904.779\,mm^{3}$

If on the unit circle C , the distance from P (1, 0) to the point T ( 5/13, 12/13 ) is x , determine the coordinates of the poin

Lorico [155]

Answer:

T' $(\frac{5}{13},- \frac{12}{13})$

Step-by-step explanation:

See the diagram attached.

This is a unit circle having a radius (r) = 1 unit.

So, the length of the circumference of the circle will be 2πr = 2π units.

Now, the point on the circle at a distance of x along the arc from P is T $(\frac{5}{13},\frac{12}{13})$ .

Therefore, the point on the circle at a distance of 2π - x along the arc from P will be T' $(\frac{5}{13},- \frac{12}{13})$ , where, T' is the image of point T, when reflected over the x-axis. (Answer)

Find an equation for the parabola with focus at (-5,-4) and vertex at (-5,-3)

sattari [20]

Answer:

$(x+5)^{2}=-4(y+3)$

Step-by-step explanation:

Given:

Focus point = (-5, -4)

Vertex point = (-5, -3)

We need to find the equation for the parabola.

Solution:

Since the x-coordinates of the vertex and focus are the same,

so this is a regular vertical parabola, where the x part is squared. Since the vertex is above the focus, this is a right-side down parabola and p is negative.

The vertex of this parabola is at (h, k) and the focus is at (h, k + p). So, directrix is y = k - p.

Substitute y = -4 and k = -3.

$-4 = -3+p$
