Circle O has a diameter of length 16. A point C is located outside of the circle such that it lies 12 units from the circle's center. What would the length of a segment drawn from C tangent to circle O be? Express your answer in simplest radical form.

The Length of a segment drawn from C tangent to circle O is

AC = x = 9 units

Step-by-step explanation:

Given data

From the Δ OAC

Radius of circle OA = 8 units

OC = 12 units

AC = Length of a segment drawn from C tangent to circle O = x

We know that in  Δ OAC

x = 8.9 units ≈ 9 units

Therefore Length of a segment drawn from C tangent to circle O is

AC = x = 9 units

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

a² + b²= c²

24² + 7² = c²

c= 25
