Equation of a circle:
(x - h)^2 + (y - k)^2 = r^2
In this case:
<span>center (2,7) and radius 4 so h = 2, k = 7 and r = 4
</span>Equation:
(x - 2)^2 + (y - 7)^2 = 4^2
(x - 2)^2 + (y - 7)^2 = 16
Hope it helps.
Answer: 49/9
Step-by-step explanation:
9x5=45
45+4=49
2y is 2y, so it is equal to 17383.
IF you were looking for just y, than the answer is 17383/2 = y = 8691.5
Answer:
$780
Step-by-step explanation:
15x60 = 900 900 - 120 = $780
I dont really feel like graphing it out but i can explain it. so lets say that you had some graph points and when you drew them together it was the shape of a circle so make a line down that circle and the rule is if that circle passes through that line you drew more than 2 times it is not a function, and if it only passes through that line once then it is a function.
