Answer:
Step-by-step explanation:
Let's just see what happens if we do
(-32)^(1/5)
That means what number do you start with that when multiplied 5 times gives you - 32?
The answer is - 2
-2 * - 2 * -2 * -2 * -2 = -32
Now when you have a root sign that goes to the 1/5 power, you can take out 1 of the factors and throw the other 4 away.
take one - 2 from under the root sign and throw the other 4 away
That's not the answer. We have one more step.
What is -2 to the 3rd power.
(-2)^3 = - 8
So the answer is -8

Step-by-step explanation:
The missing figure is attached.
Notice in the first picture that Alberta has a complex shape.
You can calculate the area of a complex shape by decomposing it into polygons whose areas can be calculated easily.
Observe the second picture. Notice that it can be descompose into two polygons: A trapezoid and a rectangle.
The area of the trapezoid can be calcualted with the formula:
Where "h" is the height, "B" is the long base and "b" is short base.
And the area of the rectangle can be found with the formula:
Wkere "l" is the lenght and "w" is the width.
Then, the apprximate area of Alberta is:
Substituting vallues, you get:
Therefore, the area of of Alberta is about .
