Answer:
C(0,6)
Step-by-step explanation:
1) find the length of the base of the triangle
AB = 7-3 = 4
2) find the the height of the triangle
A = (base x height)/2
A x 2 = base x height
height = (A x 2)/base
height = (12 x 2)/4 = 6
3) find the equation of the line that passes threw the points AB
the two points have the same y so the equation of the line is
y = 0
4) use the formula of the distance between a point and a line to find C
|ax+by+c|/√a^2 + b^2 = distance
x = 0
y = 6
C (0,6)
Answer:
r = 6.4/(1+sin(θ))
Step-by-step explanation:
As the attachment shows, for the given directrix and eccentricity, the equation is ...
![r=\dfrac{ed}{1+e\sin{\theta}}\\\\r=\dfrac{1.6\cdot 4}{1+1.6\sin{\theta}}\\\\\boxed{r=\dfrac{6.4}{1+\sin{\theta}}}\qquad\text{matches the 2$^{\text{nd}}$ choice}](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7Bed%7D%7B1%2Be%5Csin%7B%5Ctheta%7D%7D%5C%5C%5C%5Cr%3D%5Cdfrac%7B1.6%5Ccdot%204%7D%7B1%2B1.6%5Csin%7B%5Ctheta%7D%7D%5C%5C%5C%5C%5Cboxed%7Br%3D%5Cdfrac%7B6.4%7D%7B1%2B%5Csin%7B%5Ctheta%7D%7D%7D%5Cqquad%5Ctext%7Bmatches%20the%202%24%5E%7B%5Ctext%7Bnd%7D%7D%24%20choice%7D)
In my opinion i think it’s D.parallelogram
Answer:
c. The mean is the same as the average. The average is (6 * 5 + 7 * 4 + 8 * 7 + 9 * 10 + 10 * 4) / (5 + 4 + 7 + 10 + 4) = 244 / 30 = 8.133.
