Answer:
Step-by-step explanation:
+ we have
[sin(x)]^2 + [cos(x)]^2 = 1
so [cos(x)]= 1- [sin(x)]^2 = 1- (1/2)^2 = 1- 1/4 = 3/4
Then cos(x) can take one of two values;
+ cos(x) =
then tan(x)= sin(x)/cos(x) = (1/2)/ () =
+ cos(x) = -
then tan(x)= sin(x)/cos(x) = (1/2)/ (- ) = -
Have a good day
Answer:
How would we find out in real life how much each shirt cost? We'd subtract 7.99 from 71.83 and divide the difference by 3, right??
Let's work that backward. Let's say a shirt cost $6. Three would cost $3(6), or $18. Since each shirt costs $s, our price for 3 shirts is $3s. We have to add shipping to get a total, which we are given. When writing an equation, we leave out labels like $ or meters or books or whatever.
3s + 7.99 = 71.83

The lake whose flood level represents an outlier is Ozark.
<h3>What is an outlier?</h3>
An outlier is a number that is way smaller or way larger than that of other numbers in a data set. The flood level of Ozark is way greater than the other flood levels.
