I Believe It’s 2x^5-5x^4-6x^3
23, 879 to the nearest thousand.
The thousand digit is the 3, and we look at the digit after 3, which is 8, since 8 is more than 5, we round up the 3 to 4.
Therefore 23, 879 to the nearest thousand ≈ 24, 000
I hope this explains it.
C=2πr
We have 3/4 of circumference
(3π/2)*2π=3/4.
and it is equal 5π/2.
(3/4)*C=(3/4)*2πr
5π/2 = 6πr/4
5/2=6r/4
r=(5/2)*(4/6)=(5*4)/(2*6)=5/3
r=5/3
For one you have to find the circumference of the which is 3.14 times diameter then divide 5280 which is a mile by the circumference that would be the answer
for two you have to take 1920 which is the 80 times 24, then take the circumference of the earth and divide it by 1920
