On the number line, move 4 units to the right. End at -2. The dolphin was 2 feet below sea level.
<h3>What is number line?</h3>
A number lines are the horizontal straight lines in which the integers are placed in equal intervals.
A dolphin was swimming 6 feet below sea level. It then swam up 4 feet.
So, -6+4= -2 feet
As, from the information
On the number line, move 4 units to the right. End at -2. The dolphin was 2 feet below sea level.
This is because the dolphin 6 feet below sea level and swam up 4 feet.

Answer:
12,600
Step-by-step explanation:
1/3 = 4/12
1/4 = 3/12
Together they equal 7/12
The different is 5/12
5/12 = .416666 =.42
.42 x 30,000 = 12,600
Answer:
Step-by-step explanation:
Given that there is a function of x,
Let us find first and second derivative for f(x)
When f'(x) =0 we have tanx = 1 and hence
a) f'(x) >0 for I and III quadrant
Hence increasing in 
and decreasing in 
Hence f has a maxima at x = pi/4 and minima at x = 3pi/4
b) Maximum value = 
Minimum value = 
c)
f"(x) =0 gives tanx =-1
are points of inflection.
concave up in (3pi/4,7pi/4)
and concave down in (0,3pi/4)U(7pi/4,2pi)
