Answer:
3/2
Step-by-step explanation:
Solve 4 (x - 9) = -30.
4x - 36 = -30
4x = 6
x = 6/4 = 3/2
Answer:
the distance is: ![\sqrt{80}](https://tex.z-dn.net/?f=%5Csqrt%7B80%7D)
Step-by-step explanation:
We use he distance formula:
distance = ![\sqrt{(-9 + 1)^2+(3+1)^2}=\sqrt{64+16} =\sqrt{80}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-9%20%2B%201%29%5E2%2B%283%2B1%29%5E2%7D%3D%5Csqrt%7B64%2B16%7D%20%20%3D%5Csqrt%7B80%7D)
Answer:
<u>Frequency = 1/period =
</u>
Step-by-step explanation:
The frequency of the sinusoidal function = 1/period
Frequency is how many the function repeats itself per unit if time i.e: per "1"
For the given graph :
, Where: B = 2π/period
period = 2π/B , B = 1/4 = 0.25
∴ Period = 2π/0.25 = 8π
∴ Frequency = 1/period = ![\frac{1}{8\pi }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%5Cpi%20%7D)
Answer:
I think your answer would be 12x - 2
If this is wrong then im sorry
Answer:
x = 30
Step-by-step explanation:
The interior angles of a triangle must always add up to 180.
2x + 2x + 3x - 30 = 180
Add 30 to both sides to seperate variables.
2x + 2x + 3x = 210
Combine like terms.
7x = 210
Divide by 7 to isolate x.
x = 30
