We effectively rewrite the equation as

In order for the LHS to be defined, we need to restrict
, or
. Now, the LHS will vanish when the numerator is 0, which happens for

This value is indeed smaller than 4, so the solution is
.
Answer:
C
Step-by-step explanation:
47.1
you do 3.14 times 15.
The answer x = 11 is correct for problem 4. Nice work.
Use this x value to find the answer in problem 5. From problem 4, we're told that Romeo runs at a speed of 5 m/s. If he runs for x = 11 seconds,then he runs a total distance of:
5*x =(5 m/s)*(x meters) = (5 m/s)*(11 seconds) = 5*11 = 55 meters
The answer to problem five is 55 meters
Answer:

Step-by-step explanation:
Find the function by taking the intergral of the derivative.
-b - 3b = -16 -2b
Put -b and -3b together
-4b = -16 -2b
Add 2b to both sides
-2b=-16
Divide by -2
b=8
