Answer:

(1)The error is in third step.

The correct solution is (x-5)²

(2)The error is in third step.

The correct solution is (4c+3)(4c-c)

Step-by-step explanation:

(a-b) whole square is the sum square of a and b and subtraction of product of 2,a and b.

(a-b) = a²+b²-2ab

Therefore,

x²-10x+25

=x²-2.x.5+5²

=(x-5)²

The error is in third step.

The correct solution is (x-5)²

The subtraction of square of b from square a is the product of sum of a and b and the subtraction a from b.

(a²-b²)=(a+b)(a-b)

16c²-9

=(4c)²-3²

=(4c+3)(4c-c)

The error is in third step.

The correct solution is (4c+3)(4c-c)

The internet was used by 30% of the population of a state in 2008. If 3200 people were surveyed, how many in the survey were usi

andrew-mc [135]

1. We know that 30% expressed as a decimal is 0.30

Since 30% of people were using the internet, 0.30*3200 is our answer.
3200*0.30= 960.

Therefore 960 people were using the internet out of the 3200 surveyed.

Find an equation of the sphere with center (2, −10, 3) and radius 5. $$25=(x−2)2+(y−(−10))2+(z−3)2 use an equation to describe i

lana66690 [7]

In the $x,y$ plane, we have $z=0$ everywhere. So in the equation of the sphere, we have

$25=(x-2)^2+(y+10)^2+(-3)^2\implies(x-2)^2+(y+10)^2=16=4^2$

which is a circle centered at (2, -10, 0) of radius 4.

In the $x,z$ plane, we have $y=0$ , which gives

$25=(x-2)^2+10^2+(z-3)^2\implies(x-2)^2+(z-3)^2=-75$

But any squared real quantity is positive, so there is no intersection between the sphere and this plane.

In the $y,z$ plane, $x=0$ , so

$25=(-2)^2+(y+10)^2+(z-3)^2\implies(y+10)^2+(z-3)^2=21=(\sqrt{21})^2$

which is a circle centered at (0, -10, 3) of radius $\sqrt{21}$ .
