Answer:
D is the right one
Step-by-step explanation:
π radian = 180 degree
-> 135 degree = π radian
-> 135 degree = 0.75 * π radians = 3π/4 radian

Answer:
160 lbs = 72.57kg
Step-by-step explanation:
This can be solved as a rule of three problem.
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.
Unit conversion problems, like this one, is an example of a direct relationship between measures.
Each lb has 0.45kg. How many kg are there in 160lbs. So:
1lb - 0.45kg
160 lbs - xkg
kg
160 lbs = 72.57kg
To solve this completion exercise you must apply the proccedure shown below:
1. You have the first function:
y=-0.2x²
When you give different values to "x" and plot it as it is shown in the graph attached, you obtain a parabola.
2. Now, you have the second function:
y=x²
When you give different values to "x" and plot it as it is shown in the graph attached, you obtain a parabola.
3. When you see the two graphs attached, you can conclude the the answer is the option D):
