2. t = 26
3. c= 16
4. y= 13
5. y= -9
6. s= -4
7. x= -2
8. x= 4
9. x= -2/7
10. y= 28/5
27 divided by 3 = 9
9 times 5 = 45
The circumference of a circle is found using the formula:
,
where R is the radius of the circle. So the circumference of our circle is
(ft).
The ratio of the arc length to the circumference is equal to the measure of the central angle to the complete angle. That is:
.
.
Answer: 11.8 (ft)
If we call the speed of the dog d and the speed of the child c, the dog's speed can be given as a function d(c) of the child's speed by the formula
d(c) = 5.5c
Always, the proportions make it so
