False, the mean is found by adding all the numbers. Dividing the answer by how many number we're in total

for example: 5 + 12 + 4 + 2 +11= 34

34 ÷ 5 = 6.8

A piece of cloth is folded into a square with a side length measuring x inches. When it is unfolded, it has an area of x2 + 27x

marusya05 [52]

we have

$x^{2} + 27x + 162$

Using a graph tool------> to resolve the second order equation

the solution is

$x=-18\\ x=-9$

$x^{2} + 27x + 162=(x+18)*(x+9)$

therefore

the answer is the option

length = (x + 18) inches and width = (x + 9) inches

Find the equation of the sphere in standard form centered at (−6,10,5) with radius 5.

Dovator [93]

Answer:

The equation of the sphere in standard form is

$x^{2} +y^{2}+z^{2} +12 x-20 y-10 z+136=0$

Step-by-step explanation:

Step 1:-

The equation of the sphere having center and radius is

$(x-h)^{2} +(y-k)^{2} +(z-l)^{2} = r^{2}$

Given centered of the sphere is (-6,10,5) and radius r=5

$(x-(-6))^{2} +(y-10)^{2} +(z-5)^{2} = 5^{2}$

on simplification,we get

$using (a+b)^{2} =a^{2} +2 a b+b^{2}$

$using (a-b)^{2} =a^{2} -2 a b+b^{2}$

simplify , we get

$x^{2} +y^{2}+z^{2} +12 x-20 y-10 z+136=0$
