Answer:
0.2 = 1/5
Step-by-step explanation:
Convert 0.2 into a fraction.
You get 2/10.
Now simplify that number by dividing both the numerator and the denominator by 2.
You get 1/5.
Since 1/5 = 1/5, 0.2 and 1/5 are equivalent.
Answer:
.6601
Step-by-step explanation:
to find u, which we assume is an angle of course, we can take arctan of both sides. so arctan(-7.721) = -1.4420. this angle is in quadrant 4, but it is not in the range. In this instance you just go around the circle again, or add 2pi, which gets us 4.8412. You can check and you get the same answer if you take the tangent of either.
So now we have a number in the appropriate range in the appropriate quadrant. That means we have the correct angle. The question asks what is sine of that angle cut in half. so sin(4.8412/2), which gets you your answer. let em know if something didn't make sense.
Answer:
The answer you are looking for is 28.7 circumference can refer to circles like a bicycle
Step-by-step explanation:
First, find the equation of the lines:
y=-2x+2 and y=1/3x+2
We see that the shaded part is below the y=1/3x+2 graph, so it becomes y<1/3x+2 (It's not ≤ since it's a dotted line)
For the y=-2x+2, the shaded part is under the line as well, so it becomes y≤-2x+2 (Here, we include the ≤ since it's a solid line)
So your answer is y<1/3x+2 and y≤-2x+2.
