Answer:
cos(x) = square root 2 over 2; tan(x) = 1
Step-by-step explanation:

was, before it was rationalized,

Therefore,

The side opposite the reference angle measures 1, the hypotenuse measures square root 2. That makes the reference angle a 45 degree angle. From there we can determine that the side adjacent to the reference angle also has a measure of 1. Therefore,
and
since tangent is side opposite (1) over side adjacent (1),
tan(x) = 1
Given condition is:
A sloth moves in one hour = 

So, a sloth moves in one hour = 
Hence, in 60 minutes a sloth moves = 400
In 1 minute sloth will move = 
In 90 minutes it will move = 
The answer is 600 units.
Answer:
Step-by-step explanation:
Usimg formula for calculating compound interest.
A = P(1+r/n)^nt
P is the principal =$250
r is the rate = 5%
t is the time = 25years
n = 1/4(compounded quarterly)
Substituting to get the amount A.
A = 250(1+5/25)^25/4
A = 250(1+0.2)^6.25
A = 250(1.2)^6.25
A = 250(3.125)
A = $781.31
Hence the accumulated amount in Jessica's annuity after 25 years is $781.31
