Answer:
x = 1 degree
Step-by-step explanation:
Using the Pythagorean theorem, 
we can find the unknown side then use SOHCAHTOA to find the unknown angle
First step:
Take the square root of both sides
Now to find the angle use SOHCAHTOA
Cosine = 
(The side we found is adjacent)(Hypotenuse is the longest side)
= 
= 0.999
Approximately 1 degree.
Answer:
55 YRS
Step-by-step explanation:
T=INTEREST X 100%/PRINCIPAL X RATE
T=4400X100%=440000%/4000 X 2%
T=440000%/8000%
T=55 YRS
The answer to the question is A.
The equation of the graph is given by y = cos(0.4x) and has an amplitude of 1
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Since the curve crosses the y-axis at y = 1, hence it is a cosine graph. It has a maximum of 1 and a minimum of negative 1, therefore the amplitude is 1
Also, the angular frequency = 2π * 1/5π = 0.4
The equation of the graph is given by y = cos(0.4x) and has an amplitude of 1
