Answer:
Using the concept of speed-distance-time, we find that the diameter of the circular path is 12 inches.
Step-by-step explanation:
Given that the object completes one revolution in 8 seconds. So, the circular speed of the object is 2πr/8 = πr/4 inches per seconds, where r is the radius of the circular path. The speed can be written as:
πr/4 inches per seconds = 60πr/4 inches per minute = 15πr inches per minute.
But, it is given that the circular speed of the object is 90π inches per minute. So,
90π = 15πr
r = 6 inches
Since, diameter is the double of radius, d = 2r = 12 inches.

Ik its messy but i hope this helps:]
Step-by-step explanation:
The formula to find the circumference is
C=d×(3.14)
Therefore you must work backwards to find the radius.
If the circumference is x then divide both sides of the equation by pie to get the diameter. Then once you have the diameter you divide that number by two to get the radius.
Answer: Jason's baseball card is going up in value
Step-by-step explanation:
25(1.02) = 25.5
when we add in the amount of year it will always increase
25(1.02) 2 = 51
So it has to increase in value, no matter what.
Simplify this quadratic function given in vertex form into standard form by simplifying the exponents and adding like terms.
