Answer:
(x-9)^2 +(y-12)^2 = 225
Step-by-step explanation:
First find the length of the radius
If is the distance from the center to the point
d = sqrt( (x2-x1)^2 + (y2-y1)^2 )
= sqrt( (0-9)^2 + (0-12)^2)
= sqrt ( 81+144)
= sqrt(225)
= 15
The equation for a circle is
( x-h) ^2+ (y-k)^2 = r^2
(x-9)^2 +(y-12)^2 = 15^2
(x-9)^2 +(y-12)^2 = 225
10th b.day=300
11th=300+200=500
12th=500+200=700
13th=700+200=900
14th=900+200=1100
15th=1100+200=1300
16th=1300+200=1500
17th=1500+200=1700
18th=1700+200=1900
So,the daughter will receive an amount of 1900..
Thanks!
Answer:
radius is 9 m and diameter is 2 x9 = 18
Answer: 99, 100, 101. 102, 103
Step-by-step explanation:
Divide 505÷5 to get the middle integer, 101.
From that, subtract 2 to get the lowest integer, 99.
Add 101 + 2 for the greatest integer, 103. Fill in the other two integers and put them in consecutive order.
5y = 2x.....y = (2/5)x
y = (2/5)x
10y = 4x.....y = 4/10x....y = (2/5)x
5xy = 2....y = 2/(5x) <==== this does not belong because it is not a linear equation like the rest of them are.
