The circle below is centered at the point (2,-1) and has a radius of length 3. what is iis equation?

Step-by-step explanation:

The equation of a circle having center (h,k) and radius r is given by :-

Given: Vertex of circle= (2,-1)

Radius of circle= 3 units

Then the equation of a circle will be :

Hence, the equation of circle =

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
