In division, exponents with the same base are subtracted.
example:
Answer:
4/5 is ur answer
Step-by-step explanation:
ok just like the last one but this one is COS
ok so we know that COS is A/H
A= adjacent and ofc H= hypotenuse
so lets see its the COS of a which means it will be A/H
A= 4 and the H=5
First I need to know is the price of each potato.. Once I know the price it will be simple to find the answer.
Answer:
Step-by-step explanation:
Consider the figure as the difference of a trapezoid and a rectangle.
<u>Area of the trapezoid:</u>
- a = 3 - (-2) = 5 units
- b = 9 - (-6) = 15 units
- h = 5 - (-5) = 10 units
- A = (a + b)h/2 = (5 + 15)(10)/2 = 100 square units
<u>Area of the rectangle:</u>
- l = 5 - (-2) = 7 units
- w = -1 - (-5) = 4 units
- A = lw = 4*7 = 28 square units
<u>Area of the figure:</u>
- 100 - 28 = 72 square units
It is fine that you did not include the measure of angle XYZ in your posting.
This question is testing your knowledge of the four types of transformations.
1) Translations - an item is "slid" to a new location.
2) Reflections - an item is "flipped" (usually over the x-axis or y-axis)
3) Rotations - an item is rotated, usually around the origin (the point (0,0) is the center of most rotations, especially in high school math).
4) Dilations - an item is enlarged or reduced by a certain ratio.
It the first three, the image after the transformation is congruent to the pre-image. It has the same size and shape. It is simply flipped, rotated, slid...
But... in the fourth, dilation, the image now has a different size. It is still, however the same shape.
In geometry terms, after the first three transformations, the image is still "congruent" to the pre-image. After dilation, the image is "similar" but not "congruent."
So... all that to say that when you rotate an angle around the origin, the measure of the angle doesn't change.
So the first choice is correct. The measure of the image of the angle is the same as the measure of the angle.
