Answer:

Step-by-step explanation:
we are given a expression
we are said to solve it using L'Hôpital's Rule
recall, L'Hôpital's Rule:

it is to say the ' means derivative
our given expression:

let's apply L'Hôpital's Rule

some formulas of derivative




use sum derivative formula to simplify:

simplify using exponents using exponent derivative formula:

use variable derivative formula to simplify variable:

use constant derivative formula to simplify derivative:

simplify addition:

since we are approaching x to 2
we can substitute 2 for x

simplify multiplication:

simplify addition:

hence,

<span>x - 2y
= -3 - 2(-6)
= - 3 + 12
= 9</span>
The answer is 3x+2 over (x+2) (x-2)
Answer:
a) 122.5 m ; b) 10 s
Step-by-step explanation:
Just use the given equation and plug in what you know.
a)
d = 4.9t^2
d = 4.9(5^2)
d = 4.9 * 25
d = 122.5 m
b)
d = 4.9t^2
490 = 4.9t^2
100 = t^2
t = 10 s
