Have a great time studying.
No, it does not always have to be a decimal although it is more common to have one.
Answer: you want to make a math problem up???
Step-by-step explanation:
Answer:
C.
Step-by-step explanation:
Multiplying identical variables together is identical to adding the exponents of each.
In this case, you have three
s. You can multiply these to create
.
Now, you have
.
Negative exponents mean that the base (b in this scenario) is on the opposite side of the fraction line.

Answer: see graph
<u>Step-by-step explanation:</u>
Look at the Unit Circle to see the coordinates of the quadrangles.
Build a sine table for one period (0° - 360°).
<u> x </u> <u> y = sin(x) </u> <u> y² = (sin(x))² </u> <u> (x, y²) </u>
0° sin(0°) = 0 (0)² = 0 (0°, 0)
90° sin(90°) = 1 (1)² = 1 (90°, 1)
180° sin(180°) = 0 (0)² = 0 (180°, 0)
270° sin(270°) = -1 (-1)² = 1 (270°, 1)
360° sin(360°) = 0 (0)² = 0 (360°, 0)
Now plot the (x, y²) coordinates on your graph.
