Answer:
<u>{2, 4, 6, 8}</u>
Step-by-step explanation:
The domain refers to all the possible x values of a function.
Our ordered pairs :
As they are in the form (x, y), the domain is :
⇒ <u>{2, 4, 6, 8}</u>
30 inches @ 500 rpm = 15,000 inches per minute
15,000 inches per minute = 900,000 inches per hour (multiply by 60)
1 mile = 5,280 feet (google-able fact you shouldn't have to memorize)
1 foot = 12 inches (you probably already know this)
900,000 inches = 75,000 feet (divide by 12)
75,000 feet = 14.20454545454545. . . miles (divide by 5280)
Linear velocity in miles per hour is 14.20454545454545. . . miles per hour.
2 I think
because 180 times 2 is 360. And then it would be a full angle.
Answer:
b² - 121
Step-by-step explanation:
(b +11)(b - 11)
b² - 11b + 11b - 121
