Answer:
280
Step-by-step explanation:
50% is half, so to get the total, multiply 140*2 which is 280.
Solution:
As given Square L M NO is dilated by a scale factor of two about the center of the square to create square L'M'N'O'.
Original line of Dilation = Along P Q
New Dilated line = P'Q'
As scale factor > 1
1. Image Size > Pre image size
2. The two images will be similar.
3. Length of Dilated Line P' Q' = 2 × Length of PQ
As you can see from the diagram drawn below, Dilated line P'Q' will contain the point P and Q.
All four points P,Q,Q',P' are collinear , lie in the same line.
Option (2) dilated line P'Q' will contain the points P and Q is true.
Answer: y = (x - 6)^2
work:
y = x^2 - 12x + 36
y = (x - 6) (x - 6)
y = (x - 6)^2
Answer:
all sides are 16 ft
Step-by-step explanation:
If the side length is x, the area is x²=256, hence x = √256 = 16
Answer:12.59
Step-by-step explanation:

From the diagram you can see that we have constructed a right triangle, with height A and base 15.
Length of shadow = 15 feet.
Height of flagpole = A.
We know the angle of elevation is
40
∘
. Using this angle and the tangent ratio, we can find A.
