A sinusoid is cyclical and has a period or frequency.
y = sin x is a sinusoid, with a period of 2π.
y = √x is not a sinusoid.
y = cos x is a sinusoid with a period of 2π.
Answer: y = √x is not a sinusoid.
Step-by-step explanation:
marlena steps should look like this:
2x + 5 = -10 - x
(minus 5 from both sides)
2x = -15 - x
(add x to both sides)
3x = -15
(divide by 3)
x = -5
Rise over run is y over x. 9/5 is 1.8 you have x=20 i plugged in all numbers and when i plugged in 36 i got 1.8 so im sure the answer is D)36
Answer:
D
Step-by-step explanation:
The correct answer is D, try graphing them on desmos.
