The terminal side of 0 is in quadrant II and cos 0 = -5/13. What is sin 0?
2 answers:
Answer:
Step-by-step explanation:
We are given that:
Recall that cosine is the ratio of the adjacent side to the hypotenuse. Using the Pythagorean Theorem, solve for the opposite side (we can ignore the negative for now):
And since θ is in QII, sine is positive, and cosine and tangent are both negative.
Sine is the ratio of the opposite side to the hypotenuse. Therefore:

The graph is missing, so i have attached it.
Answer:
From 0 hours to 2 hours.
Step-by-step explanation:
From the attached graph, we can see that on the y-axis, denotes the level of ibuprofen in the patient’s bloodstream while the x-axis denotes the amount of hours after the ibuprofen was taken.
Now, looking at the graph, we can see that the curve goes up from a time of 0 hours which corresponds to 0 mg of ibuprofen to a time of 2 hours which corresponds to 400 mg of ibuprofen.
After that point, the curve begins to to go down. Since we are concerned with increase, we will make do with the first statement.
Thus, we can say the period at which the level of ibuprofen increased was from 0 hours to 2 hours.
The solution of the absolute inequality |y + 8| ≤ 2 is -10 ≤ y ≤ -6
<h3>What is an equation?</h3>An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Given the equation:
|y + 8| ≤ 2
Hence:
y + 8 ≤ 2; and -(y + 8) ≤ 2
y ≤ -6 and y ≥ -10
The solution of the absolute inequality |y + 8| ≤ 2 is -10 ≤ y ≤ -6
