Answer:
AB = 8.0
Step-by-step explanation:
Law of Sines
AB/sin53 = 7/sin44
multiply both sides by sin53
AB = 7/sin44 * sin53
use calculator
AB = 8.047766798861355
Rounded
AB = 8.0
Answer:
X 1 for Y 4
X 5 for Y 8
X 2 for Y 5
Step-by-step explanation:
We can substitute the values of Y in the formula and then subtract three from both sides.
Answer:
![y=-4x^{2} +7x+6\\](https://tex.z-dn.net/?f=y%3D-4x%5E%7B2%7D%20%2B7x%2B6%5C%5C)
Step-by-step explanation:
![y=ax^{2} +bx+c\\](https://tex.z-dn.net/?f=y%3Dax%5E%7B2%7D%20%2Bbx%2Bc%5C%5C)
Points are (1,9), (2,4), and (4,-30).
![\\9=a+b+c\\4=4a+2b+c\\-30=16a+4b+c\\](https://tex.z-dn.net/?f=%5C%5C9%3Da%2Bb%2Bc%5C%5C4%3D4a%2B2b%2Bc%5C%5C-30%3D16a%2B4b%2Bc%5C%5C)
Subtract the first from the second.
-5 = 3a+b
Subtract 4 times the second from the third.
-34=12a+2b
-14=-2b
b=7
a=-4
c=6
Answer: 2
Explanation:
The scale factor is the ratio between the scale drawing measures and the actual measures.
scale drawing length 8 inches
scale factor = ratio = -------------------------------- = --------------- = 2
actual length 4 inches
Also,
scale drawing width 14 inches
scale factor = ratio = ----------------------------- = --------------- = 2
actual width 7 inces
As seen the scale factor is 2.
