5) cos (t) = 1
Where on the Unit Circle does cos = 1?
Answer: at 0π (0°) and all rotations of 2π (360°)
In radians: t = 0π + 2πn
In degrees: t = 0° + 360n

Answer:
a +d = a2
Step-by-step explanation:
-2 - (-9) =
-2+9=7
a + d = a2
Answer:
298 cm^2.
Step-by-step explanation:
There are 3 pairs of faces of equal area.
Area of top = 7 * 11. So it's 2 * 7 * 11 = 154.
Area of a smaller side = 7 * 4 so we have 2*28 = 56 .
Area of larger side = 4*11 so it's 2*44 = 88.
Total surface area = 154 + 56 + 88
= 298.
You have to use this equation the a=5, h=4 and b=9 and you should get the answer of 28
So an equation of any line is y=mx+b.
We know that the m, or slope, equals 3.
y=3x+b
Now we find the b, or the y-intercept, by substituting the x and y values into their places.
4=3*1+b
4=3+b
b=1
Now that we have the y-intercept, we just substitute the m and b into the equation and receive our final answer:
y=3x+1
