Find the center and the radius of the circle defined by the equation x^2-8x+y+12y+36=0

choli [55]

Hello,
center is (4,-6)
radius=4
since
$x^2-8x+y^2+12y+36=0\\

x^2-2*4x+16-16+y^2+2*6y+36=0\\

(x-4)^2+(y+6)^2=4^2

z varies jointly with x and y. When x = 2 and y = 3, z = 60. What is the value of z when x = 4 and y = 9?

kondor19780726 [428]

2 x 3 = 6 x 10 = 60
Assuming that you are using the same rule:
4 x 9 x 10 = 360
The value of z when x = 4 and y = 9 is 360. Hope this helped!

Consider the sequence Two-fourths, three-fifths, four-sixths, StartFraction 5 Over 7 EndFraction, ellipsis Which statement descr

Phoenix [80]

Answer:

The sequence converges to 1

Step-by-step explanation:

Given

$\frac{2}{4}. \frac{3}{5}, \frac{4}{6}, \frac{5}{7},...$

Require

Description of the sequence

The given sequence follows:

$\frac{2}{4}. \frac{3}{5}, \frac{4}{6}, \frac{5}{7},... \frac{n+1}{n+3}$

i.e.

$T_n = \frac{n+1}{n+3}$

For every term,

$\frac{n+1}{n+3} < 1$

In other words,

as the value of n increases, $\frac{n+1}{n+3}$ approaches 1

Hence, (c) is true

What is the volume of a hemisphere with a radius of 2.3m round to the nearest tenth of a cubic meter

kodGreya [7K]

Answer: $25.5 m^{3}$

Step-by-step explanation:

If the volume of a sphere is

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

Where $r=2.3 m$ is the radius

The volume of a hemisphere is half the volume of the total sphere:

$V_{hemisphere}=\frac{V}{2}=\frac{\frac{4}{3} \pi r^{3}}{2}$

$V_{hemisphere}=\frac{2}{3} \pi r^{3}$

Solving this equation:

$V_{hemisphere}=\frac{2}{3} \pi (2.3 m)^{3}$

Finally:

$V_{hemisphere}=25.48m^{3} \approx 25.5 m^{3}$
