Hi there!

Since ST is a tangent to the circle, we can use the relationship: tangent squared = external secant segment x entire secant segment.

WORK:
(I will be using x in place of ST)
x^2 = 7(23 + 7)
x^2 = 7(30)
x^2 = 210
x = squareroot(210) or approximately 14.5 inches

Hope this helps!! :)

The area of a circular rose garden is 44 square meters. What is the radius of the garden?
Tasya [4]
The area of a circle is:

a=πr^2  dividing both sides by π

r^2=a/π  taking the square root of both sides

r=√(a/π), in this case a=44 m^2 so:

r=√(44/π) m^2

r≈14.01 m^2  (to the nearest hundredth of a square meter)

Find the domain and range of the function
SVEN [57.7K]

Answer:

domain: (-∞ , ∞)

range: (-∞, 2]

Step-by-step explanation:

the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2

range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.
