Step-by-step explanation:
area of ∆ ACB = 1/2× AB×CP
= 1/2× 16× 21 m²
=8×21m²
= 168m²
optionC
The domain of the provide function where the function is defined is x less than the number three.
<h3>What is the domain of the function?</h3>
Domain of a function is the set of all the possible input values which are valid for that function.
The function given in the problem is,

The above function is the function of logarithm. For the logarithmic function, it is defined for all the real numbers except 0.
Thus, the function should be greater than zero as,

Change the sign of both side, by changing the inequality,

Thus, the domain of the provide function where the function is defined is x less than the number three.

Answer:
An irrational number is any number than cannot be written in the form p/q, where q is 0 Ex. pi, non-perfect squares
Step-by-step explanation:
In this case D. isn't rational but is irrational
Answer:
Domain = {All real values of x EXCEPT x = -5 and x = 7}
Step-by-step explanation:
This is a rational function given as y=\frac{6+9x}{6-|x-1|}y=
6−∣x−1∣
6+9x
The domain is the set of all real value of x for which the function is defined.
For rational functions, we need to find which value of x makes the denominator equal to 0. We need to exclude those values from the domain.
Now
6 - |x-1| = 0
|x-1| = 6
x- 1 = 6
or
-(x-1) = 6
x = 6+1 = 7
and
-x+1=6
x = 1-6 = -5
So, the x values of -5 and 7 makes this function undefined. So the domain is the set of all real numbers except x = -5 and x = 7
Answer:
2/3
Step-by-step explanation:
Everytime the line moves over 3 it goes up 2, so the run is 3 and rise is 2. It is written in rise over run.
