Rewriting in polar form makes this trivial.
We have
(not to be confused with the standard inverse tangent function . Here is the inverse tangent function that takes into account position in the coordinate plane; look up "atan2" for more information)
So we have
Then
so that and .
Answer:
4-13 is -9 and -9 to the 4th power is 6561 -6 is 6555
Then you do 25/5 which is 5 so 6555 over 5 is 1311
1311 minus the absolute value of -2 which is 2 so 1311 minus 2 is 1309
Step-by-step explanation:
1309
Step-by-step explanation:
The area of a parallelogram is base times height. You are given the base and the height of each parallelogram, so you can find their areas.
Red parallelogram:
area = base * height = 12 yd * 7 yd = 84 sq yd
Blue parallelogram:
area = base * height = 24 yd * 3 yd = 72 sq yd
Each parallelogram is made up of 6 parts whose areas are equal. To find the area of each piece of the red parallelogram, we divide 84 sq yd by 6.
Red parallelogram piece:
area = 84 sq yd/6 = 14 sq yd
Blue parallelogram piece:
area = 72 sq yd/6 = 12 sq yd
Now we know that each small red polygon has area 14 sq yd, and each blue polygon has area 12 sq yd.
Part A: 52 sq yd
52 = 14 + 14 + 12 + 12
Use 2 small red polygons and 2 small blue polygons.
Part B: 70 sq yd
70 = 5 * 14
Use 5 small red polygons.
Part C: 36 sq yd
36 = 3 * 12
Use 3 small blue polygons.
A triangle equals 180° so set up the equation as
58+73+12x+1=180
132+12x=180 (I got 132 by adding 58,73,1)
Subtract 132 from both sides
You should get 12x=48
Divide both sides by 12
X=4
Answer:
11
Step-by-step explanation:
Work backwards and reverse the operations to find the original number.
Reverse the operations for add four: 8 - 4 = 4
Reverse the operations for take the square root: 4² = 16
Reverse the operations for subtract six: 16 + 6 = 22
Reverse the operations for double the number: 22 ÷ 2 = 11
