P = 60 meters
l = 4 meters
60 / 4 = 20 <-- Because retangles have 4 sides.
If l=4 then subtract 4 from 20
So w=16
Answer:
The speed of the cheetah is 108 kilometer per hour.
Step-by-step explanation: i found this by taking 1 hour or 60 divided by the 5 for minutes. That was 12 then since the cheetah ran 9 km in 5 minutes i multiplied 9 by twelve to get kph.
This is the answer. Let me know if i'm correct.
Answer:
(x+4)² + (y-6)² = 81
Step-by-step explanation:
<u>General equation of a circle :</u> (x-h)² + (y-k)² = r²
where (h,k) is at center and r = radius
Here we are given that the circle has a center at (-4,6) and a radius of 9
So we have (h,k) = (-4,6) so h = -4 and k = 6 and radius = 9 so r = 9
<u>Plugging in values into general equation</u>
Recall that the general equation of a circle is (x-h)² + (y-k)² = r²
we have h = -4 , k = 6 and r = 9
==> plug in values
doing so we acquire (x-(-4))² + (y-6)² = 9²
==> apply double negative sign rule
(x+4)² + (y-6)² = 9²
==> evaluate exponent
(x+4)² + (y-6)² = 81
And we are done!
