Answer:
AB = b - a
Step-by-step explanation:
AB = -OA + OB
AB = -a + b we usually write the positive vector first
AB = b - a
We know that P divides AB in the ratio 3:1 so PB = 1/4 AB
AB is negative as we are going in the opposite direction
OP = OB - 1/4 AB
OP = b - 1/4 (b - a)
multiplying inside the brackets:
OP = b - 1/4b + 1/4a
OP = 3/4b + 1/4a

The complete question is
"On a piece of paper, graph f(x) = 4. (0.5)^x Then determine which answer choice matches the graph you drew."
The given function is an exponential function. The graph of option C is the correct answer.
<h3>What are exponential functions?</h3>
When the expression of function is such that it involves the input to be present as an exponent (power) of some constant, then such function is called exponential function.
There usual form is specified below. They are written in several such equivalent forms.
For example,
, where a is a constant is an exponential function.
The function is given as
f(x) = 4. (0.5)^x
AS we can see that the given function is an exponential function.
Thus, the graph of option C is the correct answer.

Answer:
The statement is false
Step-by-step explanation:
The lines mean the absolute value of whatever is inside of them. Therefore you can never get a negative number equal to it.
