Answer:
Domain (Basically means the sets of values of x-axis).Hence, the set of values of domain is given by -3<domain<1. Meaning domain lies between values more than -3 and less than 1.
Range (Basically means the sets of values of y-axis). Hence, the set of values of range is given by -1<range<3. Meaning that range lies between values more than -1 and less than 3.
Function basically means the equation of the given circle. We know that equation of circle is given by;
(x-h)^2+ (y-k)^2 = r^2 [where (h, k) is the center of circle and r is the radius of circle]
From the figure,
(h, k)= (-1 ,1) and r= 2.
So, we can conclude that function is given by equation:
(x-(-1))^2 + (y-1)^2 = 2^2
(x+1)^2 + (y-1)^2 = 4.
Answer:
wth is up with your workbook answer is 4 i think
Step-by-step explanation:
Answer:
The initial distance between Wade and Alexandra is 240ft.
They walk towards each other.
Alexandra walks twice as fast as Wade.
Now, because they are walking towards each other, when the distance walked by both of them equals 240 ft, they will meet.
Then:
if Wade walks z ft, Alexandra walks 2*z ft.
So we have the equation:
Distance that Wade walked + Distance that Alexandra walked = 240ft
z + 2*z = 240ft
3*z = 240ft
z = 240ft/3 = 80ft
They will meet when Wade walks 80ft.
