Answer:
Step-by-step explanation:
y = tan(48 + 19/60 + 23/3600)
y = tan(48.323055555...)
y = 1.1232851096924531815531574029372...

Answer:
a. Decay
b. 0.5
c. 4
Explanation:
If we have a function of the form

then
a = intital amount
b = growth / decay rate factor
x = time interval
If b > 1; then the equation is modelling growth. If b < 0, then the equation is modelling decay.
Now in our case, we have

Here we see that
inital amount = a = 4
b = 1/ 2 < 0, meaning the function is modeling decay
decay factor = b = 1/2
Therefore, the answers are
a. Decay
b. 0.5
c. 4
Answer:
C
Step-by-step explanation:
y < 1/3x -4
The y intercept is -4
The slope is 1/3
y is less than so the line is dotted
y is less than so we colour below the line
