To find the center solve for x and y:

x + 9 = 0

x = -9

y + 6 = 0

y = -6

So the center is (-9, -6).

The radius is the square root of 9, which is 3.

So the answer is Option B.

You can do this by comparing your equation to the general form of equation of a circle

( x - a)^2 + (y - b)^2 = r^2       where (a,b) is the centre and r = radius:-
(x  + 9)^2   (y + 6)^2 = 9 

so (a,b) = (-9,-6)  and r = 3

so the answer is B

ipn [44]

Maya is cleaning out her closet and is shocked when she realizes that she has 55 shirts. She decides to donate 40% of them. How many more shirts does she have for her ?

Answer:

The number of T-shirt that Maya will have after donating 40% is 22 shirts

Explanation:

Given:( as per the above data provided)

Total number of T-shirts = 55

Percentage of T-shirts she wish to donate = 40%

To find:

Remaining number of T-shirt left after donating?

Formula to be used:

Remaining T shirt = (Total number of T-shirt /100) X The Percentage of T-shirt she wish to donate

Steps:

Substituting all the above provided values in the formula we get,

              = (55/100)*40

              = 22 shirts.

Thus the number of T-shirts left with her is 22.

Find an equation of the plane. the plane through the point (−5, 9, 10) and perpendicular to the line x = 1 + t, y = 4t, z = 2 −
PtichkaEL [24]
The direction vector of the line
L: x=1+t, y=4t, z=2-3t
is <1,4,-3>
which is also the required normal vector of the plane.

Since the plane passes through point (-5,9,10), the required plane is :
&Pi; 1(x-(-5)+4(y-9)-3(z-10)=0
=>
&Pi; x+4y-3z=1
