Answer: 471.24
<u>Explanation:</u>
angular speed (w) = 
= 4π radians/hour
linear speed (v) = r * w
= 
= 150π meters/hour
≈ 471.24 meters/hour

I think that this systems have One solution
Answer:
Area = 
Step-by-step explanation:
If both length and width are increase by 2x meters each, then:
New length = 30 + 2x
New Width = 20 + 2x
We know area of rectangle = length * width
Thus the new rectangle will have an area of :
Area = length * width = 
<u>Note:</u> Standard form of a polynomial is writing the terms in order (highest order comes first and so on)
Hello,
Answer: m = 2
Step-by-step explanation:
m - 2 = 2 - m
⇔ m - 2 + m = 2 - m + m
⇔ 2m - 2 = 2
⇔ 2m - 2 + 2 = 2 + 2
⇔ 2m = 4
⇔ 2m/2 = 4/2
⇔ m = 2
