The range is the high and low points.
So (5, 2]
Answer:
Step-by-step explanation:
Given
The given equation is a differential equation
By separating variable
⇒
Now by taking integration both side
⇒
Where C is the constant
from above equation we can say that
When t will increases in positive direction then 
will decreases it means that 
will increases, so y will decreases. Similarly in the case of negative t.
No. Área of a circle is determined by this formula A=πr^2. Answer is 153.94
Short Answer B
Remark
You need not do any calculations to get the answer. You are required just to read the graph. Doing the calculations would be beneficial but unnecessary.
Step One
Find the x value.
1. If you have a ruler or a straight edge of some kind, put it on the cross point of the two graphs.
2. Make the ruler go straight up and down. You will find out it goes 1 point back of the 5.
3. Count the number of squares from 0,0 or when y = 0.
4. You will find you have to count 4 squares along the x axis.
The x value is 4.
Step Two
1. Put the ruler on the cross point again. This time make it go straight across.
2. Count up from (0,0)
You should get 8.
The y value is 8
Answer: (4,8)
