r equals start fraction cap a minus one over t end fraction
r = A − p − pt
Answer:
The answer is B, r = "A - p / pt."
Step-by-step explanation:
I just took the test and got a 100% with this answer. I hope this helps!
B)write an equation of the line tangent to the graph of f at the point where x=1
C) find the x coordinate of each point at which the line tangent to the graph of f is parallel to the line y=-2x+4
A convenient way to find the zeros of is by factoring.
a) The equation,
can be rewritten as,
We can think of this equation as a quadratic equation in , with .
Observe that .
We find two factors of 2 that adds up to . These are, .
Now let us split the middle term. to obtain;
We can factor to get,
We factor further to obtain;
Hence the zeroes of are;
b) To find the line tangent, we must first, find the slope using differentiation. That is,
At ,
Also, we need to determine the value at . That is;
Now we can use the slope and the point to write ythe equation of the line tangent.
c)
If the line tangent is parallel to the line , then
Since parallel lines have the same slope.
Hence the x-coordinates are,
