Hello :
an equation is : (x+2)² +(y-7)² = 4
x² +4x+4 +y² -14y +49 = 4
x² +4x+y² -14y +49 = 0 ....( answer : 3)
Answer:
P = 8.6 m
Step-by-step explanation:
Given that,
The length of a rectangle = 2.5 m
The width of a rectangle = 1.8 m
We need to find the perimeter of the rug. The perimeter of a rectangle is given by :
P=2(l+b)
= 2(2.5+1.8)
= 8.6 m
So, the perimeter of the rug is 8.6 m.
We are given equation c=50p.
c is the total cost and p is the number of people.
Let us take number of people by groups of 10, 20, 30,40 people.
Note: We can take any positive integer for number of people in a group.
Now, we need to plug p=10, 20, 30,40 one by one in given function c=50p to find the costs c.
Plugging p=10, we get
c= 50*10 = 500.
Plugging p=20, we get
c= 50*20 = 1000.
Plugging p=30, we get
c= 50*30 = 1500.
Plugging p=40, we get
c= 50*40 = 2000.
So, we can create a table as.
Number of people (p) Total cost (c)
--------------------------------------------------------------------
10 500
20 1000
30 1500
40 2000
