The circle given by x^2+y^2-6y-12=0 can be written in standard form like this: x^2+(y-k)^2=21 What is the value of k in this equ

sweet [91]

Answer:

The value of k =3

Step-by-step explanation:

$x^2+y^2-6y-12=0$ We need to solve this equation to become in standard form to find the value of k.

$x^2+y^2-6y-12=0\\x^2+y^2-6y = 12\\(x)^2 +(y^2-2(y)(3)+(3)^2) = 12 +(3)^2\\(x)^2+(y-3)^2 = 12+9\\(x)^2 +(y-3)^2 = 21$

The given standard form is:

$x^2+(y-k)^2=21$

Comparing it with $(x)^2 +(y-3)^2 = 21$

The value of k =3

Please help by solving with method. Thanks

Answer:

(a) AD=6 cm

(b) 66 cm²

Step-by-step explanation:

(a) To get the length of AD, we can use pythagoras on the triangle part. Let's say the dotted line intersects DC at E. Then since AB and DC are parallel, AD is equal to BE. EC = 8 cm simply by subtracting AB from DC (15-7=8).

Then pythagoras says that 8²+BC²=10². So BC = √(100-64) = 6. And since BC=AD, AD is also 6.

(b) Area of the rectangle DEBA is 7*6 = 42. Area of triangle ECB is base times half height: 8*3 = 24. Sum is 42+24 = 66 cm²
