Answer:
how do you have to answer it so i can give you the answer
Step-by-step explanation:
Answer:
it's B
Step-by-step explanation:
the set of numbers for which a function is defined is called a domain of a function
if a number is not in the domain of a function, then the function is undefined for that number
denominator must not be zero
if we plug -3 then the y
=(-3+1)/(9+-3-6)
=(-2)/9-9
=-2/0
which is undefined for x=-3
now
if we plug 2 we have
(2+1)/(4+2-6)
=3/0
the function is undefined for x=2
so
x≠3, x≠2
Answer:
Point T is on the circle
Step-by-step explanation:
To check where the point lies, we need to find its distance to the center of the circle.
The distance between two points (x1, y1) and (x2, y2) is given by:
![distance = \sqrt[2]{(x2 - x1)^{2} + (y2 - y1)^{2}}](https://tex.z-dn.net/?f=distance%20%3D%20%5Csqrt%5B2%5D%7B%28x2%20-%20x1%29%5E%7B2%7D%20%2B%20%28y2%20-%20y1%29%5E%7B2%7D%7D)
If the first point is O(0,0) and the second is T(5, -2), we have:
![distance = \sqrt[2]{(5 - 0)^{2} + (-2 - 0)^{2}}](https://tex.z-dn.net/?f=distance%20%3D%20%5Csqrt%5B2%5D%7B%285%20-%200%29%5E%7B2%7D%20%2B%20%28-2%20-%200%29%5E%7B2%7D%7D)
The distance between the points is equal the radius of the circle, that means the point T is on the circle.
Expression A = (18500)(0.96)^3t, implying that at t = 1/3 years = 4 months, the exponent will be 1, meaning that the value will be multiplied by 0.96 (which is a decrease of 4%). This fits the third choice.
Expression B has a factor of (1.18)^t/3, implying that at t = 3 years, the exponent will be 1, meaning that the value is multiplied by 1.18, which is a growth of 18%. This also fits the third choice.
