Answer:
centre = (0, 0 ), radius = 5
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 25 ← is in this form
with centre = (0, 0 ) and r = 
= 5
The unit rate is 15 meters per second.
60 / 4 = 15
I hope this helps :)
Answer:
there are 12
Step-by-step explanation:
24/2 = 12 that means that there are 12 cycles per stand
You can solve this by convert mixed number(s) into improper fraction(s) 2. change both fractions to the equivalent fractions with the same denominator 3. omit denominators and write numerators as a ratio 4. simplify the ratio by dividing both numbers by the highest common factor.
The answer is 2/25, this should be hepful!
