The basic rigid motions are A) Translation, reflections and rotations
In other words, we can shift an object, mirror it over a line, or turn it, to keep the same basic size and shape of the object. The object keeps the same area and perimeter, as well as the angles and sides staying the same as well.
A transformation that isn't a rigid motion would be a dilation. A dilation enlarges or shrinks a figure, so it doesn't keep the same size (though it keeps the same shape to make the before and after figures similar).
-------------------------
A turn is also called A) rotation
A rotation needs to have information about what center point you're turning around. Often this is the origin. You'll also need the amount of rotation applied, as well as if you're going counterclockwise or clockwise.
7 / (1/2)...when dividing with fractions, flip what u r dividing by, then multiply
7 * 2/1 = 14/1 or just 14
Mary added 3/4 cups milk + 3 cups flour + 2/8 cups butter while baking. Her total batter = 3 cups.
3/4+3+2/8
3/4+12/4+1/4=16/4 = 3
Answer:
f(x) = 16 * ( 3/4) ^x
Step-by-step explanation:
y = a ( b) ^x
where a is the initial value and b is the growth rate
We know when x =0 y = 16
and when x = 1 y = 12
16 = a * b^0
16 = a * 1
a = 16
So the initial value is 16
12 = 16 * b^ 1
Divide each side by 16
12/16 = b^1
3/4 = b
y = 16 * ( 3/4) ^x
