Answer:
8 ft
Step-by-step explanation:
Consider the attached diagram.
The rule for secants and tangents tells us ...
(AC)(AB) = (AT)²
AC = AT²/AB = 15²/9 = 25
Then the diameter is ...
BC = AB - AC = 25 -9 = 16
The pond has a diameter of 16 ft, so a radius of 8 feet.

<em>Additional comment</em>
Since point C is the nearest point on the edge of the pond to point A, it must lie on line AO. Hence BC must be a diameter.
No, simplified: 12x^2-15x=12x-5
Your answer should be true
Answer:
x^2y^2 3y^2
Step-by-step explanation:
its a or the first choice
Equation given:
15x - 6y = 48
First, turn 15x into -15x and plug it into 48.
15x - 6y = 48
-15x -15x
The equation should look like this:
-6y = -15x + 48
Divide -6y to 48 and -15x.
y = - 8
