A. 8 * 3 = 24
b. -7 * 5 = -35
c. -6 * -9 = 54
d. 8 / -2 = -4
e. -24 / -3 = 8
f. -36 / 6 = -6
Question 2
Note: Let t = theta since I there is no theta symbol on my keyboard.
(0, -1) = (cos t, sin t)
cos t = 0
sin t = -1
I read the answer from the given point.
On the unit circle, the point (0, -1) lies at 3pi/2. So, angle theta is 3pi/2.
tan t = sin t/cos t
tan t = cos t ÷ sin t
Therefore, tan t = what?

Answer:
x = 19.5 ( to the nearest tenth )
Step-by-step explanation:
Since the triangle is right, we can use the cosine ratio to find x
cos46° = =
multiply both sides by 28
x = 28 × cos46° = 19.450 ≈ 19.5
Answer:
The slope is 3/7 or ~0.43
Step-by-step explanation:
The equation for slope is y2-y1/x2-x1
7-4=3
10-3=7
3/7=0.428
