Answer:

The answer to your question is below

Step-by-step explanation:

The answers for 1, 3 and 4 are given in decimals and roots.

1)  \sqrt{2^{2} - 4(3)(-6)}

    \sqrt{4 + 72}

    \sqrt{76}

    2\sqrt{19} = 8.71

2) \sqrt{1^{2} -4(1)(-6)}

    \sqrt{1 + 24}

    \sqrt{25}

     5

3) \sqrt{1^{2} - 4(1)(-11)}

   \sqrt{1 + 44}

    \sqrt{45}

     3\sqrt{5} = 6.7

4) \sqrt{8^{2} -4(5)(2)}

    \sqrt{64 - 40}

    \sqrt{24}

     2\sqrt{6} = 4.89

Step-by-step explanation:

Kx = u - y

Divide both sides by k

X = <u>u</u><u> </u><u>-</u><u> </u><u>y</u>

K

I think that's the answer

Hope it helps:)

You are correct. For each of the three possibilities for their second day, there are two possibilities for the third day.

The total number of possibilities is 3*2 = 6.

If the endpoints of the diameter of a circle are (6, 3) and (2, 1), what is the standard form equation of the circle?
Anastasy [175]
If the endpoints of a diameter are (6,3) and (2,1) the midpoint is the center of the circle so:

(x,y)=((6+2)/2, (3+1)/2)=(4,2)

Now we need to find the radius....the diameter is:

d^2=(6-2)^2+(3-1)^2

d^2=16+4

d^2=20  since d=2r, r=d/2, and r^2=d^2/4 so

r^2=5

The standard form of the circle is (x-h)^2+(y-k)^2=r^2 and we know:
 
(h,k)=(4,2) from earlier so:

(x-4)^2+(y-2)^2=5

Help stuck on methods question ​
andreev551 [17]

Answer:

x=3

Explanation:

Let's write an equation for the area of this figure.

This figure can be divided into 2 rectangles, a vertical and horizontal rectangle.

Area of rectangle= length× breadth

Area of vertical rectangle= 6x

Length of horizontal rectangle= (7 -x) cm

Area of horizontal rectangle= x(7-x)

Since total area= 30 cm^2,

6x+ x(7-x)= 30

6x +7x -x^2= 30 (expand)

-x^2 +13x-30= 0 (bring all terms to one side)

x^2 -13x +30= 0 (divide by -1)

(x -10)(x -3)= 0 (factorise)

x -10= 0 or x -3= 0

x= 10 or x= 3

(reject)

We reject x=10 since from the diagram, x cm is less than 6cm.
