Answer:
D.) Not enough information
Step-by-step explanation:
The marks are the same, but they aren't placed in the same position in the triangles.
Answer: vertical line.
Step-by-step explanation:
Ok we can define a function f(x) as "something" that maps a given input (we usually call the input "x") into a given output (we usually call the output "y")
We have one rule for functions, each input can be mapped into only one output.
So if for example, for a given value x = A.
f(A) = B
and
f(A) = C
This is mapping the input A into two different outputs, then this is not a function.
Now to the question.
If we have a vertical line (parallel to the y-axis)
This line will have only one value of x associated with it, but all the values of y.
This means that this maps one value of the input into infinite outputs, then this can not be a function.
Answer:
x = log 7
Step-by-step explanation:
10^x=7
Take the log base 10 on each side
log10 (10^x)=log10 (7)
We dont need to write the 10, it is implied
log(10^x)=log (7)
The exponent goes out front since log a^b = b log a
x log 10 = log 7
log 10 = 1 since the base is 10 log10(10) =1
x = log 7
Although I'm going to answer this question, I have to point out that this problem is NOT stated clearly. The problem being we don't know if angle AMV is a right angle.
But I'm assuming it is and thus we need to use the Pythagorean theorem.
AV=
AV=13
Therefore answer is C. :D
