The answer is B. Would you like an explanation why?
B. 5 you subtract -4-1 divided by 1-2 and so the negatives cancel out and the answer is 5/1 or 5
Answer:
Step-by-step explanation:
scale factor:
1/2
the coordinates of the new vertices are
A (-4/2, -8/2)
A:(-2, -4)
B (-2/2, 34/2)
B: (-1, 17)
C (6/2, 12/2)
C:(3, 6)
D (10/2, -30/2)
D:(5, -15)
I guess the dilation is 2 times bigger?
Answer:
Option D is correct.
Step-by-step explanation:
We have been given a function:
![0=-16t^2+22t-8](https://tex.z-dn.net/?f=0%3D-16t%5E2%2B22t-8)
We will find at h=0 to find the time it will take until it lands outside the hole, having gone up and come back down.
In the given function we will put h=0.
![-16t^2+22t-8=0](https://tex.z-dn.net/?f=-16t%5E2%2B22t-8%3D0)
On solving the above equation we will get t
![t=\frac{1}{16}(11-i\sqrt{7})\text{and}{\frac{1}{16}(11+i\sqrt{7})](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B1%7D%7B16%7D%2811-i%5Csqrt%7B7%7D%29%5Ctext%7Band%7D%7B%5Cfrac%7B1%7D%7B16%7D%2811%2Bi%5Csqrt%7B7%7D%29)
So, it will never happen we are getting time as imaginary value.
Hence, it will not make it outside the hole.
Therefore, option D is correct.
