Pavel [41]

Answer:

6

Step-by-step explanation:

Radius of the given circle is 6 units.

Given equation of circle is:

{(x + 5)}^{2}  +  {(y - 7)}^{2}  = 36 \\  \: equating \: it \: with \\  {(x  -  h)}^{2}  +  {(y - k)}^{2}  =  {r}^{2}  \\ {r}^{2}   = 36 \\  \huge \red{ \boxed{r = 6 \: units}}

Elena L [17]

Answer:

Standard Form           Equivalent Form            Extreme Values

y=x^2-6x+17                   (x-3)^2+8                        (3,8)

y=x^2+8x+21                  (x+4)^2+5                        (-4,5)

y=x^2-16x+60                 (x-8)^2-4                         (8,-4)

Step-by-step explanation:

1) Standard form:

y=x^2-6x+17

Equivalent Form:

Can be found using completing the square method.

y=x^2-6x+17\\y=x^2-2(x)(3)+(3)^2-(3)^2+17\\y=(x-3)^2-9+17\\y=(x-3)^2+8

So, Equivalent form is: (x-3)^2+8

Extreme value:

Extreme values are basically the minimum and maximum value of the function.

Minimum Value will be found by finding derivative of the function:

The derivate is: 2x-6

Now, put the derivate equal to zero: 2x-6 = 0

2x=6\\x=6/3 \\x=3

Maximum value can be found by putting minimum value in the given function:

Put x = 3 and solve:

(3)^2-6(3)+17\\9-18+17\\9-1\\=8\\

So, the extreme values is: (3,8)

2) Standard form:

y=x^2+8x+21

Equivalent Form:

Can be found using completing the square method.

y=x^2+8x+21\\y=x^2+2(x)(4)+(4)^2-(4)^2+21\\y=(x+4)^2-16+21\\y=(x+4)^2+5

So, Equivalent form is: (x+4)^2+5

Extreme value:

Extreme values are basically the minimum and maximum value of the function.

Minimum Value will be found by finding derivative of the function:

The derivate of x^2+8x+21 is: 2x+8

Now, put the derivate equal to zero:

2x+8 = 0\\2x=-8\\x=-8/2 \\x=-4

So, minimum value is: -4

Maximum value can be found by putting minimum value in the given function:

Put x = -4 and solve:

x^2+8x+21\\=(-4)^2+8(-4)+21\\=16-32+21\\=5

So, Maximum value is: 5

So, the extreme values is: (-4,5)

3) Standard form:

y=x^2-16x+60

Equivalent Form:

Can be found using completing the square method.

y=x^2-16x+60\\y=x^2-2(x)(8)+(8)^2-(8)^2+60\\y=(x-8)^2-64+60\\y=(x-8)^2-4

So, Equivalent form is: (x-8)^2-4

Extreme value:

Extreme values are basically the minimum and maximum value of the function.

Minimum Value will be found by finding derivative of the function:

The derivate of x^2-16x+60 is: 2x-16

Now, put the derivate equal to zero:

2x-16 = 0\\2x=16\\x=16/2 \\x=8

So, minimum value is: 8

Maximum value can be found by putting minimum value in the given function:

Put x = 8 and solve:

x^2-16x+60\\=(8)^2-16(8)+60\\=64-128+60\\=-4

So, Maximum value is: -4

So, the extreme values is: (8,-4)
