Find the value of x, rounded to the nearest tenth.

Answer:
The answer is C. 6.2
Step-by-step explanation:
In order to determine the "x" value, we have to know about right triangles.
A right triangle is triangle with an angle of 90 degrees (pi/2 radians). The sides a, b, and c of such a triangle satisfy the Pythagorean theorem .
where the largest side is conventionally denoted c and is called the hypotenuse. The other two sides of lengths a and b are called legs, or sometimes catheti.
Also, there are some relations called "trigonometric relations". These formulas relation the angles and sides of a right triangle.
I have attached an image that shows the trigonometric relations in a right triangle.
According to the image,
Angle=20 degrees
Opposite side= X
Hypotenuse= 18
We use the "sine" trigonometric relation:
The rounded result to the nearest tenth is 6.2, so the answer is C.

Answer:
c. quarterly
Step-by-step explanation:
To start with 1 year is equal to twelve months
3months out of 12 months will be;
3/12= 1/4
Here it is compounded quarterly and n=4 where n is the number of compoundings a year.
Lets study the compound interest formula;
where;
A=The ending amount
P=Starting amount
r=rate of interest expressed as a decimal
n=number of compoundings a year
t=total number of years
The number of compoundings in any one year can be an interest compounded yearly where n=1, semi-annually with n=2, quarterly where n=4, monthly where n=12, weekly and n=52 and finaly daily with n=365.
