<h3>Answers are:
sine, tangent, cosecant, cotangent</h3>
Explanation:
On the unit circle we have some point (x,y) such that x = cos(theta) and y = sin(theta). The sine corresponds to the y coordinate of the point on the circle. Quadrant IV is below the x axis which explains why sine is negative here, since y < 0 here.
Since sine is negative, so is cosecant as this is the reciprocal of sine
csc = 1/sin
In quadrant IV, cosine is positive as x > 0 here. So the ratio tan = sin/cos is going to be negative. We have a negative over a positive when we divide.
Because tangent is negative, so is cotangent.
The only positive functions in Q4 are cosine and secant, which is because sec = 1/cos.
Answer:
true
Step-by-step explanation:
i go to k12 i did this test
Mark points (0,0), (-1,-1), (1,-1), (-2,-4), (2,-4)
The horizontal change is called the run and the vertical is rise. so for example if one point to the other rises by 4 and runs by 5, the slope is 4/5. slope is
rise / run
Answer:
5
Step-by-step explanation:
number of chocolate chip cookies = 36 × ¼ = 9
number of oatmeal cookies = 36 × ⅓ = 12
36 - 9 - 12 = 15
Alex made 15 peanut butter cookies.
