Answer:
option 4 is right
Step-by-step explanation:
Consider the trignometric function y =cotx
Since cot x has sin x in denominator, cot x is undefined whenever sinx =0
OR whenever x =n π, for any integer n, cot x is undefined
Hence domain =(-∞,∞) ,x≠nπ
Range = -∞<y<∞
since cotx can take any real values
The graph y=cotx will be a periodic function discontinuous at all integral multiples of pi and undefined for integral multiples of pi.
It is not defined for x=0 also
It passes through (pi/4,1) (npi/2,0)
i.e. x intercepts are odd multiples of pi/2
and it takes value 1 for pi/4, 5pi/4, .....

Answer:
t=4 seconds to reach the cannon floor
Step-by-step explanation:
ax^2+bx+c=0
0=-16t^2+255
-255=-16t^2
t^2=15.9375
t= 3.99
round it up...
t=4 seconds to reach the cannon floor
hope this helps!!! :)
Answer:
Step-by-step explanation:
We can use the exponential growth formula:
y = a(1 + r)ˣ
where
y = amount after x time
a = initial amount
r = growth rate as a decimal fraction
x = years since 2013
Data:
y = 2300
r = 0.12
x = 2022 - 2013 = 9
Calculations:
x = 2022 - 2013 = 9
