How do you do this question?

daser333 [38]

Answer:

B. 1/2

Step-by-step explanation:

$\lim_{z \to 0} \frac{g(z)e^{-z}-3}{z^{2}-2z}$

If we plug in 0 for z, we get 0/0. Apply l'Hopital's rule.

$\lim_{z \to 0} \frac{-g(z)e^{-z}+g'(z)e^{-z}}{2z-2}$

Now when we plug in 0 for z, we get:

$\frac{-g(0)e^{0}+g'(0)e^{0}}{2(0)-2}\\\frac{-g(0)+g'(0)}{-2}\\\frac{-3+2}{-2}\\\frac{1}{2}$

If line segment AB represents 25%, what is the length of a line segment that is 100%?

kicyunya [14]

If I am correctly understanding the question, I think the length of the line segment would be 4AB

Step-by-step explanation:

25% = 1/4

AB = 1/4

100% = 4/4

AB*4 = 4AB

Multiply AB by 4 to find the value that 100% would equal, resulting in 4AB.
