The standard equation of the circle is:
(x-h)^2+(y-k)^2=r^2 where (h,k) it the center of the circle and r is the radius...
so
30.
(x-2)^2+(y-7)^2=16
31.
We need to find the radius...(I'll just use the Pythagorean Theorem)
r^2=6^2+8^2
r^2=36+64
r^2=100 (so the radius is 10) and its center is (-6,-8) so
(x+6)^2+(y+8)^2=100
Answer:
id take it but don know how
Step-by-step explanation:
Answer:
Total Distance : 1*60 +60=120
Total time taken = 1+ 60/30= 1+2=3
Hence average speed for the trip = 120/3= 40 kmph
Hence Answer is 40
Step-by-step explanation:
Answer:
it will be a positive number that is even
Step-by-step explanation:
this is because two negative numbers multiplied make a positive and two odd number multiplied make an even.
please leave a thanks if im correct
Answer:
≈ 38.64 units
Step-by-step explanation:
The length of arc s is calculated as
circumference of circle × fraction of circle
The central angle subtended by arc s is 360° - 114° = 246° then
arc s = 2πr × 
= 2π × 9 × 
= 18π ×
≈ 38.64 ( to 2 dec. places )
