Step-by-step explanation:
Just did the quiz!
to get the equation of any straight line, we simply need two points off of it, well, let's use the provided values hmmm
Answer:
x² + (y+3)² = 4²
Step-by-step explanation:
A close look at the diagram reveals that the center of this circle is (0, -3) and that the radius is 4 units.
Starting from the general equation of a circle, (x - h)² + (y - k)² = r²
and substituting the givens (h = 0, k = -3, r = 4), we get:
x² + (y+3)² = 4². This is Answer B.
15/28 is greater than 1/2 because if it were less than 1/2 than it would be 13/28 or lower.
Answer:
B
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° = 
, then
cos30° = 
= 
= ( cross- multiply )
2x = 20
( divide both sides by 2 )
x = 10 → B
