What is the standard form that has a center (1,3) and a radius of 9

klasskru [66]

$\huge\boxed{(x-1)^2+(y-3)^2=9^2}$

Start with the standard form of a circle, where $(h,k)$ is the center of the circle and $r$ is the radius.

$(x-h)^2+(y-k)^2=r^2$

Plug in the known values.

$\boxed{(x-1)^2+(y-3)^2=9^2}$

This is the circle's equation in standard form.

[|(x-4)÷(x+5)|]\leq[4]

Katena32 [7]

Answer:

Solutions are;

x = -8

x = -3.2

Step-by-step explanation:

Here, we want to solve the given equation for x

|(x-4)/(x + 5)| = 4

From what we have, this is an absolute value equation and thus, we are going to have two solutions

These are;

x-4/x+ 5 = 4

x-4 = 4(x + 5)

x-4 = 4x + 20

x-4x = 20 + 4

-3x = 24

x = -24/3

x = -8

secondly;

x-4/x+5 = -4

x-4 = -4(x + 5)

x-4 = -4x - 20

x + 4x = -20 + 4

5x = -16

x = -16/5

x = -3.2

Step-by-step explanation:

We know that: in order to ride a roller coaster,a rider must be greater than 49 inches tall.Jeff is 45 inches tall.

We have the next inequalitythats:

$x+45>49\\\\x>49-45\\\\x>4\\$

Therefore, we conclude that the Jeff must grow 4 inches in order to ride the roller-coaster.
