What is the domain of the function f (x) x-5/x^2-9
Answers
remember we can't divide by zero
domain is x^2-9
set to zero to find values we can't use
x^2-9=0
x^2=9
x=+/-3
domain=all real numbers except -3 and 3

Step-by-step explanation:
From the given right angle triangle,
The unknown side represents the hypotenuse of the right angle triangle.
With m∠x as the reference angle,
the adjacent side of the right angle triangle is 7.8
the opposite side of the right angle triangle is 8
To determine m∠x, we would apply
the Tangent trigonometric ratio.
Tan θ, = opposite side/adjacent side. Therefore,
Tan x = 8/7.8 = 1.026
x = Tan^-1(1.026)
x = 45.7° to the nearest tenth
In the given right triangle the measure of angle x is 45.7°. The correct option is C 45.7°
Trigonometry
From the question, we are to determine the measure which is closest to the value of x
In the diagram,
Opposite = 8
and
Adjacent = 7.8
Using SOH CAH TOA
We can write that
x = 45.7°
Hence, in the given right triangle the measure of angle x is 45.7°. The correct option is C 45.7°
Here is the Correct question:
A right triangle is shown.
Which angle measure is closest to the value of x ?
A 43.9°
B 44.3°
C 45.7°
D 46.2°

1. create two ordered pairs based on the data so (1, 90) and (3, 70)
2. plug into the slope formula so (70 - 90)/(3 - 1)
then it's -20/2, which is -10
