A circle has a center at A (4,5), Determine the radius of the circle given two end points of the circle are B (9,5) and C (-1,5)
Anna71 [15]

ANSWER :

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.

In the diagram, GB = 2x + 3..
zaharov [31]

<u>Answer-</u>

\boxed{\boxed{GB=15\ units}}

<u>Solution-</u>

From the attachment,

AD = AE, so FA is a median.

BD = BF, so BE is a median.

CF = CE, so DC is a median.

And G is the centroid.

From the properties of centroid, we know that

The centroid divides each median in a ratio of 2:1

So,

\Rightarrow FG:AG=2:1

\Rightarrow \dfrac{FG}{AG}=\dfrac{2}{1}

\Rightarrow FG=2\times AG

\Rightarrow 5x=2\times (x+9)

\Rightarrow 5x=2x+18

\Rightarrow 3x=18

\Rightarrow x=6

So, GB will be 2(6)+3=15 units

Express 7 square as the sum of two consecutive positive numbers.
Alborosie

Answer:

24 and 25

Step-by-step explanation:

From given, we have,

7 square = 49

Let the first positive number be = x

And the second consecutive positive number is = x+1

x + (x + 1) = 49

2x + 1 = 49

2x = 49 - 1

2x = 48

x = 24

the first number x = 24

the second consecutive number x+1  = 24 + 1 = 25

Thus, 7 square = 24 + 25 (the sum of two consecutive positive numbers.)
