Independent variable is 5 means x = 5
solve for f(x) when x = 5
f(5) = -2(5) +1
f(5) = -10 + 1
f(5) = -9
Solution (5,-9)
Answer
B. (5,-9)
First find a parameterization for the curve of intersection.
Given the equation of a cylinder, a natural choice for a parameterization would be one utilizing cylindrical coordinates. Here,
which suggests we could use
with 
, and we get 
from the equation of the plane,
Now use the arc length formula:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 15
In a number line its shows u were the spt of the numbers are soo. Lets say the number line goes by 2s. Its starts in 8 soo its 8, 10, 12. Go closer and its 10 , 11 , 12 . closer. 11, 11.1 , 11. 2. Untilit keeps going and u can see that 11.6 is farther to the right so that means that it is greater
9 15 *The denominator must be the same. 9 4 36
--- + ---- = --- × --- = ----
10 40 10 4 40
36 15 51 *Then simplify.
--- + --- = ----
40 40 40
51 11 * This the answer
--- = 1 ---
40 40
