16 square inches. when u do multiply you just get it so yeah
Answer:
When a figure or shape is dilated , the size of the figure either enlarges or shrank without changing its actual shape.
Shape or figure after dilation is similar to original figure.
If the scale or factor of dilation is greater than 1 the shape enlarges.
If the scale factor lies between 0<scale factor<1, then the figure shrinks i.e size reduces.
So out of all the options given →It has the same shape as the original and is smaller than the original figure.
Answer:
12
Step-by-step explanation:
(2x-8+2x+10)/2 = 25
(4x+2) = 2×25
4x+2 = 50
4x = 50-2
4x = 48
x = 48/4
x = 12
Answer:
Let the coordinate of focus be ![(\pm c , 0)](https://tex.z-dn.net/?f=%28%5Cpm%20c%20%2C%200%29)
As per the statement: The base of an auditorium is in the form of an eclipse 200 feet long and 100 feet wide.
⇒Length of Major axis=base of an auditorium = 200 feet and Length of a minor axis=wide of a auditorium = 100 ft
Semi-major axis (a) = 100 ft and
semi-minor axis(b) = 50 ft
Then, by an equation:
![c^2 = a^2-b^2](https://tex.z-dn.net/?f=c%5E2%20%3D%20a%5E2-b%5E2)
Solve for c:
Substitute the given values we have;
![c^2=(100)^2-(50)^2](https://tex.z-dn.net/?f=c%5E2%3D%28100%29%5E2-%2850%29%5E2)
Simplify:
![c^2 = 7500](https://tex.z-dn.net/?f=c%5E2%20%3D%207500)
or
ft
Distance between the foci is, ![2c = 2 \cdot 86.6025404 = 173.205081](https://tex.z-dn.net/?f=2c%20%3D%202%20%5Ccdot%2086.6025404%20%3D%20173.205081)
Therefore, the distance between the foci to the nearest 10th of a foot is, 173.2 ft
