After two days and driving 100 miles, the rental car would cost $122
Hello.
Let's first make a basic concept to solve for our answer: Divide the numerator (the number on top of the fraction) by the denominator (the number on the bottom of the fraction). This turns our fraction into a decimal.
For example;
1/2; 0.5
A terminating decimal is a number that has infinite numbers at after the decimal.
Let's apply this to our answer choices.
1/9; 0.11~ (terminating; this may be an answer choice, but let's keep going to ensure that)
3/7; 0.428571429 - this is not terminating as the decimal does not infinitely repeat.
3/4; 0.75 - this is the same as above
5/11; 0.454545455 - this is not terminating as the end decimal is not "45", but rather "55".
Your answer is "A.) 1/9"
I hope this helps!
Answer:
I think the answer is 1/2 but dont take my word
You can first use the fundamental trigonometric identity:
sin(x) ^2 + cos(x) ^2 = 1
=> cos(x) ^2 = 1 - sin(x) ^2
=> cos(x) ^2 = 1 - (-4/5)^2 = 1 - 16/25 = (25 - 16) / 25 = 9 /25
=> cos (x) = +/ - √ (9/25) = +/- 3/5
Now, analyze the sign.
In the fhird quadrant the cosine is negative, so the answer is cos(x) = - 3/5.
Answer: option C. - 3/5
