If the center is in point P(a,b) and has a radius r then circle equation is:
(x-a)²+(y-b)²=r².
In your task we've got P(0,0) so the circle equation is x²+y²=r².
We have to find r. Radius start at (0,0) and end at (-4,-6) therefore
r=√((-4)²+(-6)²) and
r²=(-4)²+(-6)²=16+36=52.
So answer is x²+y²=52.
Answer:
The slope is 0
Step-by-step explanation:
m= (y2-y1)(x2-x1)
y2 is -3, y1 is -3
x2 is 1 and x1 is -9
m= -3-(-3)/1- (-9)
m=0/10
m= 0
Answer: D
Step-by-step explanation: If you do 4/4.45 you get a number approximate to 89 cents. Answers A and B you can cross of because coconuts are 5 cents more than pineapples
Check the formula of future value of annuity ordinary (through Google)
FVOA=100[((1+0.13/12)^(12)-1/(0.13/12)]
FVOA=1274.15
Answer:
The answer would be A
Step-by-step explanation:
1^2=1×1= 1
2^2 =2×2=4
3^2=3×3=9
4^2=4×4=16
Therefore,
√11 lies between 3 and 4
