The correct answer is Choice A.
You can see from the graph that the y-intercept is 50 because it cross on the left at 50.
To find the slope, we can use the following two points (0, 50) and (20, 110). This will give a slope of 3.
Put the 50 and 3 together and you will have the equation:
y = 3x + 50
Answer:
Step-by-step explanation:
Use the cosine rule and see if the numbers hold true. a^2 = b^2 + c^2 - (2bc (cos x))
By substituting in our values I get that cos x = 0.838... which is possible. If cos x would equal 1.5, the there is no solution and the triangle would not be possible.
Answer:
12.6
Step-by-step explanation:
To find the area of a circle, you need to use the formula ![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
We have
, so we need to plug it into the formula.
![A=\pi (2)^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20%282%29%5E%7B2%7D)
![A=\pi (4)](https://tex.z-dn.net/?f=A%3D%5Cpi%20%284%29)
![A=12.5663706...](https://tex.z-dn.net/?f=A%3D12.5663706...)
Since we need to round to the nearest tenth, your final answer should be ![12.6](https://tex.z-dn.net/?f=12.6)
Circumference equals pi times the diameter, or 50 pi in this case.
Here are a few 4/1 , 8/2 , 12/3
