I will answer if u post the ?s in a coment
Find the length of the hypotenuse by using either "sine" or "cosine".
Sine= Length of opposite side/ Hypotenuse
Cosine= Length of adjacent side/ Hypotenuse
In order to use one of these, it depends on which angle they give you other than 90 degrees.
Hope this helps!
Answer:
Not C, Not A, most likely B
Step-by-step explanation:
Its less than 90 because its and acute, meaning its smaller, so you can already knock off C.
Answer:
Step-by-step explanation:
The picture is below of how to separate this into 2 different regions, which you have to because it's not continuous over the whole function. It "breaks" at x = 2. So the way to separate this is to take the integral from x = 0 to x = 2 and then add it to the integral for x = 2 to x = 3. In order to integrate each one of those "parts" of that absolute value function we have to determine the equation for each line that makes up that part.
For the integral from [0, 2], the equation of the line is -3x + 6;
For the integral from [2, 3], the equation of the line is 3x - 6.
We integrate then:
and
sorry for the odd representation; that's as good as it gets here!
Using the First Fundamental Theorem of Calculus, we get:
(6 - 0) + (-4.5 - (-6)) = 6 + 1.5 = 7.5
No, Rays go one way only since a point block te other way. Otherwise it wont be a ray :)
