Answer:
Step-by-step explanation:
Lin drew a triangle and a dilated triangle with a scale factor of .
That means image of the original triangle is smaller than the preimage.
1). Center of dilation will be point A.
Since, triangle ACB has been reduced to form triangle ADE by a scale factor of
Scale factor = =
AD =
So the center of dilation is point A.
2). Since triangle ADE is half of the triangle ACB, triangle ACB is preimage (original) and triangle ADE is an image after dilation.

Have a Nice Day!
Answer:
1059 ft
Step-by-step explanation:
For problems like these, we assume the acceleration due to gravity is -32 ft/s², so the velocity will decrease to zero in time t, where ...
0 = 256 -32t
32t = 256
t = (256 ft/s)/(32 ft/s² ) = 8 s
Since velocity is linearly decreasing from 256 ft/s to 0, its average value of 128 ft/s will serve to tell us the height attained.
Height attained is ...
35 ft + (128 ft/s)(8 s) = 35 ft + 1024 ft = 1059 ft
The maximum height attained by the projectile is 1059 feet.
Answer: 20
Step-by-step explanation:
Assuming g(x) = -4x + 1,
( -4 (-4) + 1) - (-4 + 1)
= (16 + 1) - (-3)
= 17 + 3
= 20
