To answer this let’s express it as an infinite series:
Sum from n=0 to infinity of .8(1/10)^n = .8/(1-1/10) = (8/10)/(9/10) = 8/9
I recommend learning the mnemonic SOHCAHTOA (it's very fun to say!)
Here is what SOHCAHTOA represents.
Sin - Opposite / Hypotenuse (SOH)
Cos - Adjacent / Hypotenuse (CAH)
Tan - Opposite / Adjacent (TOA)
The sine of an angle is the length of the side opposite of the angle divided by the length of the hypotenuse.
Thus, the length of the side opposite of the angle divided by the sine will give us the length of the hypotenuse.
The angle is 46 degrees. The length of the side opposite of the angle is 14. The hypotenuse is c.
The tangent of an angle is the length of the side opposite of the angle divided by the length of the side adjacent to the angle.
Thus, the length of the side opposite to the angle divided by the tangent of the angle will give us the length of the other leg.
The length of the side opposite to the angle is 14. The angle is 46. The unknown length of the side adjacent to the angle is b.
This should be what you are looking for. Enjoy!
Answer: A Person's age is usually considered a discrete variable.
Step-by-step explanation: lets say a person was born in November 2000 and the date is currently September 2020 if asked their age the person would say 19 because they have not turned 20 yet. therefore no matter what date anytime between their 19th birthday up until their 20th birthday they would say they are 19 making age a discrete variable.
