Given:
Sharon uses 6.3 pints of blue paint and white paint to paint her bedroom walls.
of this amount is blue paint and the rest is white paint.
To find:
The pints of white paint did she use to paint her bedroom walls.
Solution:
We have,
Total paint used = 6.3 pints
Blue paint = of total paint used
=
=
White paint = Total paint used - Blue paint
=
=
Therefore, Sharon uses 1.26 pints of white paint to paint her bedroom walls.
Answer:
1. Translation: g(x) = f(x-a)+b.
2. Reflection around y-axis: h(x) = f(-x)
3. Reflection around x-axis: k(x) = -f(x)
4. Rotation of 90° :
5. Rotation of 180° : .
6. Rotation of 270° : .
Step-by-step explanation:
Let us assume that the transformations namely translation, reflection are applied to a function f(x) and the rotation is applied to the point ( x,y ).
So, according to the options:
We know that 'translation moves the image in horizontal and vertical direction'.
1. As we have to translate the function f(x) 'a' units to the right and 'b' units up. So, the new form of the function becomes g(x) = f(x-a)+b.
Further, we know that 'reflection means to flip the image around a line'.
2. As, we have to reflect the function f(x) around y-axis. The new form of the function is h(x) = f(-x).
3. As, we have to reflect the function f(x) around x-axis. The new form of the function is k(x) = -f(x).
Since, 'rotation turns the image around a point to a certain degree'.
4. As, we have to rotate ( x,y ) counter-clockwise to 90° about the origin, the new form of the function is .
5. As, we have to rotate ( x,y ) counter-clockwise to 180° about the origin, the new form of the function is .
6. As, we have to rotate ( x,y ) counter-clockwise to 270° about the origin, the new form of the function is .
