Center at (h,k) and radius r is
(x-h)²+(y-k)²=r²
so given
center at (9,-8)
(x-9)²+(y-(-8))²=r²
(x-9)²+(y+8)²=r²
input the point (19,22) to find r²
x=19 and y=22
(19-9)²+(22+8)²=r²
10²+30²=r²
100+900=r²
1000=r²
10√10=r
well, the equation is
(x-9)²+(y+8)²=1000
Answer:
16 seconds
Step-by-step explanation:
So, we know that distance equals 100.
We also know that Dita covers 6.25 meters of this distance every second.
Since this is 6.25 PER second, we can write this as 6.25s, where s is seconds.
To find the seconds it takes to cover 100 meters in distance, we can write the following equation:
6.25s = 100
This makes sense, since the 100 meters in distance is equal to the rate of change in meters, times the seconds.
Now we just need to solve for s.
To do this, we must get s alone. We can do this by dividing 6.5 from both sides:
=
s = 16
So this means the seconds it takes to go 100 meters is 16 seconds, your first answer option
