Answer:
b y= 0.6x + 6
Step-by-step explanation:
When put on a calculator, you can see it passes through the points.
The equation of a circle with center (a,b) and radius r is:
(x - a)^2 + ( y -b)^2 = r^2
The center of the circle graphed is (3,4).
And the radius may be calculated using the distance formula and the points (0,0) and (3,4)
r^2 = (3 - 0)^2 + (4 - 0)^2 = 9 + 16 = 25
=> (x - 3)^2 + (y - 4)^2 = 25
Which is likely the option D, but you made a mistake when wrote the numbers.
Answer: (x - 3)^2 + (y - 4)^2 = 25

Answer:
$163,002
Step-by-step explanation:
If you're working problems of this sort, you have been shown formulas and examples. Use the appropriate formula with the numbers of this problem.
For the formula below, you have d=3000, r=0.045, k=4, N=11
P = (3000)(1 -(1 +0.045/4)^(-11·4))/(0.045/4) ≈ 163,002
The account needs to hold about $163,002 to make this possible.
Answer:
8.4
Step-by-step explanation:
d=√(x2-x1)+(y2-y1)
d-√ (-1-(-7))^2+(-1-(-7))^2
d=√ (-1+7)^2+(-1+7)^2
d=√ (6)^2+6^2
d=√ 36+36
d=√ 72
d=6√ 2=8.4852
d=8.4
