Answer:
20 seconds
Step-by-step explanation:
I assume you mean 
for your function.
As the given function is in the form of 
(some textbooks may write this formula differently), the period is equal to 
. Hence, the period of the given function is 
, or 20 seconds.
Answer:
y=6,95x+35
y=6,95*5+35=69,75 for 5 hours
for 6 hours y=76,7
for 7 hours y=83.65
for 8 hours y=90,6
Step-by-step explanation:
Answer:
y = 5
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis.
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (2, 5) with y- coordinate 5, thus
y = 5 ← equation of line

Answer:
1. (a) -√5
2. 3/5
Step-by-step explanation:
1. sec²(θ) = tan²(θ) +1
sec²(θ) = (-2)² + 1 = 5
sec(θ) = ±√5
In the second quadrant, secant is negative, so ...
sec(θ) = -√5
__
2. cos(θ) = 1/sec(θ)
cos(θ) = 1/(5/3)
cos(θ) = 3/5
