Answer:
x^2 + y^2 = 12
Step-by-step explanation:
For a circle with the center at the origin [(h,k) is (0,0)]
use the formula:
x^2 + y^2 = r^2
In this case r is 2sqroot3.
(2sqroot3)^2 is 12.
2•2•sqrt3•sqrt3
= 4•3
= 12
So we get,
x^2 + y^2 = 12
Answer:
14 : 21
Step-by-step explanation:
---> 2:3 ----> 2+3=5
---> Stick's length = 35 inches
<u />
<u>For the first portion</u>
2/5 x 35
2/1 x 7
= 14 inches
<u>For the second portion</u>
3/5 x 35
3/1 x 7
= 21 inches
To confirm: 14 + 21 = 35 inches
14 : 21
Divide both by 7
2 : 3
Answer:
Perimeter of the dog park = 15.4 yards
Step-by-step explanation:
Coordinates of the vertices of the given triangle are,
P(1, 2), Q(1, 6), R(-4, 2)
Since distance between the two points 
and 
is,
d = 
Length of PQ = 
PQ = 4
Length of PR = 
PR = 5
Length of QR = 
QR = 
= 
= 6.4 yards
Therefore, perimeter of the given triangle = PQ + QR + PR
= 4 + 6.4 + 5
= 15.4 yards
Answer:
3rd one or infinite
Step-by-step explanation:
To get the answer we can use proportion
40$ ------------- 100%
2$ ---------------- x
crossmultiply now
40x=2*100 /:40
x=200:40
x=5% - its the answer
