Answer:
CD = 4
Step-by-step explanation:
I believe you know the geometric mean for altitudes?
CD = √AD * DB = √8 * 2 = √16 = 4
If you are not aware of this theorem, then use the similarity of triangles.
ADC ~ CDB
AD/DC = CD/DB (cross-multiply)
CD^2 = AD*DB,
1= 23
2= 104
3= 90
1
Since, line is intersecting y axis at (0, 1).
Therefore, y-intercept of the graph is 1.
y= -2x + 7
Hi,
You just have to change z^25 to z^24 or z^27.
