Answer with Step-by-step explanation:
We are given that


Compare with the equation of circle

Where center of circle=(h,k)
r=Radius of circle
a.Center of circle=(0,0)
Radius=
units
Center of second circle=(3,3)
Radius of second circle=
units
b.Distance formula:
Using the formula
The distance between the centers of two circle
=
Hence, the distance between the centers of two circle =
units.
c.
Substitute x=-1 and -1


The circle must be tangent because there is just one point (-1,-1) is common in both circles and satisfied the equations of circle.
Answer:x^(4/3)y^(16/3)
Step-by-step explanation:
X^(2×2/3)y^(8×2/3)=x^(4/3)y^(16/3)
The amount of water left = 21.3 gallons.
We have a leaking pond which looses 18 gallons of water in 34 hour.
We have to determine how many gallons of water will be left after 41 hours.
<h3>What do you understand by gallon?</h3>
The gallon is a unit of volume in imperial units and United States customary units.
I gallon = 231 cubic inches = 3.785411784 liters.
According to question, we have -
Amount of water lost by the pond in 34 hours = 18 gallons
Therefore -
Amount of water lost by the pond in 1 hour = 
So, the amount of water loosed by the pond in 41 hours =
= 21.3
Hence, the amount of water left = 21.3 gallons.

Area of decagon is given by:
Area=1/2(nsr)
where:
n=number of sides
s=side length
r=height
thus the area will be given by:
Area=1/2(10*4*6.2)
Area=124 cm^2
