A few ways. you can enter it into a calculator for one, but the easiest way would be to reference a unit circle and look for an ordered pair where sin (the y value), is equal to -1/2
on a unit circle, the sin value is -1/2 at 7pi/6 and 11pi/6
because sin is the y value, it will additionally be in the quadrants III or IV based on the fact that (-1/2) as a sin value IS a negative and would have to be found in a quadrant in which sin is negative (the lower half of a coordinate plane, in this case)
Answer:
answer B is correct
Step-by-step explanation:
Hello,
this is not allowed to divide by 0 so we need to find the zeros of
we need x different from -5 and from 3
answer B is correct
hope this helps
Answer:
4
Step-by-step explanation:
Let p represent the number of pants Karter has, s represent the number of pairs of shoes he has and t the number of T-shirts he has.
Karter has 24 T-shirts.
t=24
Karter has 8 fewer pairs of shoes than pairs of pants.
p=s+8
The number of T-shirts Karter has is double the number of pants he has.
2x p= t
then
p=t/2=24/2=12
s=p-8=12-8=4
Answer
B. 6 feet by 5 feet by 4 feet
C. 7 feet by 6 feet by 4 feet
D. 8 feet by 3 feet by 7 feet
It's an isosceles triangle 45° - 45° - 90°, therefore y = 5.
In that triangle, sides are in proportion 1 : 1 : √2.
Therefore we have x = 5√2.
<h3>Answer: B. x = 5√2, y = 5</h3>
Other method.
You can use the Pythagorean theorem:
x² = 5² + 5²
x² = 25 + 25
x² = 2 · 25
x = √(25 · 2)
x = √25 · √2
x = 5√2
<h3>Answer: B. x = 5√2, y = 5</h3>
