Answer: Jane incorrectly evaluated (-2)² in step 2.
Step-by-step explanation:
, not -4.
1. If the numbers are the same, 10n +n, or 11n
.. If the numbers are different, 10a +b
2. 5(a -b)
3. 5n = 15
Answer:
Angles of rotation that produce symmetry are the angles that we can rotate the image, and the end result will be the starting image. (the angles are always measured from the x-axis)
Here we can clearly see that in each quadrant we have a petal of the flower.
Then the angles that change one quadrant into other quadrant will produce symmetry.
Those angles are:
90°, 180°, 270°, 360°, etc.
We can define the set of those angles as:
A {n*90° I n ∈ Z}
1. Find the slope using the slope formula.

2. Plug that slope and either point into an equation in slope-intercept form and solve for b.

3. Now write your answer as a slope-intercept form equation
Answer:
C≈47.25
Step-by-step explanation:
Use the formula C= πd, where C is circumference, π is pi, and d is diameter.
Input the numbers and we'll shorten π to 3.15
C=3.15(15)
C≈47.25
