Answer: 31 degrees</h3>
This is because rotations preserve angles. The angle measures won't change. That's why angle BCD is the same as angle B'C'D'. This applies to any rotation (regardless how much you rotate), any translation, any reflection, and any dilation.
Note: dilations will change the side lengths
(40 - x) ÷ 2
this is because we first deduct the difference
Answer:
Step-by-step explanation:
Complex numbers:
The following relation is important for complex numbers:
Zeros of a function:
Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.
Has zeros −19 and −i
If -i is a zero, its conjugate i is also a zero. So
Output of 40 when x=1
This means that when . We use this to find the leading coefficient a. So
The polynomial is:
Answer:
6/5
Step-by-step explanation:
A rectangle has four sides and the width and length are the same as the other width and length so 11 times 2 is 22 and 38-22 is 16 so the perimeter of the width added together is 16 so then divide them by 2 and the width of the rectangle is 8.
